In the first shooting mode and the second shooting mode, the camera module is in different light environments, and the light-emitting module illuminates the shooting object in the first shooting mode and / or the second shooting mode. The method includes:

[0005] In response to a shooting instruction, in the first shooting mode, controlling the camera module to capture a first image of the object;

[0006] The first shooting mode is switched to a second shooting mode, and after a first time period, the camera module is controlled to capture a second image of the object.

[0007] The present application discloses a shooting control device for an oral photography device, wherein the oral photography device includes a camera module and a light-emitting module. The oral photography device supports a first shooting mode and a second shooting mode. In the first shooting mode and the second shooting mode, the camera module is in different light environments, and the light-emitting module illuminates the object in the first shooting mode and / or the second shooting mode. The device includes:

[0008] a shooting control module, configured to control the camera module to capture a first image of a shooting object in response to a shooting instruction in the first shooting mode;

[0009] A mode switching module, configured to switch from the first shooting mode to a second shooting mode;

[0015] In the embodiment of the present application, the automatic shooting of images in two shooting modes can be achieved by obtaining a shooting instruction at one time, which can not only improve the shooting efficiency, but also automatically switch the shooting mode and automatically control the shooting of the camera module, reducing the user's trigger button operations, shortening the operation time, and improving the stability of the shooting, so that the image consistency of the two shooting modes is better, and the generation of problems such as ghosting caused by unstable shooting is reduced. Moreover, when switching from the first shooting mode to the second shooting mode, the camera module is controlled to capture the second image with a delay, and sufficient time is reserved for the light module to turn on and / or turn off the light source, so that the camera module is in a relatively stable light environment when capturing the second image, which can improve the image quality of the oral image captured by the oral shooting device, thereby further improving the accuracy of oral condition assessment using the oral image.

[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] It should be noted that the terms "including," "having," and any variations thereof in the embodiments and drawings of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to the process, method, product, or apparatus.

[0035] It will be understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from another element. For example, without departing from the scope of this application, the first shooting mode may be referred to as the second shooting mode, and similarly, the second shooting mode may be referred to as the first shooting mode. Both the first shooting mode and the second shooting mode are shooting modes, but they are not the same shooting mode. The term "plurality" used in this application refers to two or more. The term "and / or" used in this application refers to one of the solutions, or any combination of multiple solutions.

[0036] Figure 1 FIG. 1 is an application scenario diagram of a method for controlling the shooting of an oral shooting device in one embodiment. Figure 1 As shown, the shooting control method of the oral shooting device provided in the embodiment of the present application can be applied to the oral shooting device 110.

[0037] The oral imaging device 110 may include, but is not limited to, an oral camera, an oral endoscope, an oral scanner, and other devices. Optionally, the oral imaging device 110 may be portable, offering advantages such as small size, light weight, and ease of operation and maintenance. The portable oral imaging device 110 can meet users' daily needs for oral imaging and analysis, eliminating the inconvenience of requiring users to visit a hospital or other location to use specialized oral testing equipment for these procedures.

[0038] In some embodiments, the oral photography device 110 may include a main body 112 and a support arm 114. The main body 112 may be a housing for a controller, a battery, or other electronic components that control the operation of the oral photography device 100. For example, the main body 112 may be a handle for the user to hold. The support arm 114 may be connected to the main body 112. Furthermore, the support arm 114 is also connected to the photography unit, which may include a light-emitting module 116 and a camera module 118. The light-emitting module 116 is used to illuminate the photographed object (such as teeth in the mouth), and the camera module 118 can be used to capture images of the photographed object.

[0039] By holding the main body 112, the user can insert the camera unit deeper into the user's mouth. The light module 116 illuminates the object (such as teeth) in the user's mouth, and then the camera module 118 captures an image of the object. Furthermore, by adjusting the position and / or angle of the camera unit in the user's mouth, the camera module 118 can capture images of different areas of the mouth.

[0040] For example, Figure 2A FIG. 1 is a schematic diagram of the structure of an oral photography device in one embodiment. Figure 2A As shown, the intraoral photographing device 200 may include a main body 210, a support arm 220 connected to the main body, and a photographing unit 230 connected to the support arm 220. The intraoral photographing device 200 may further include an opener 240 detachably connected to the support arm 220 and the main body 210.

[0041] Furthermore, the mouth-opener 240 includes at least one opening, and the opening of the mouth-opener 240 corresponds to the camera module in the camera unit 230, so that the camera module can capture images through the opening of the mouth-opener 240. When the mouth-opener 240 is connected to the support arm 220 and the main body 210, the user can hold the mouth-opener 240 in their mouth or place one end of the mouth-opener 240 against the teeth. The mouth-opener 240 can open the lips and maintain the position of the user's mouth, so that when the camera module captures images of the tooth surface, the oral photography device 200 is in a stable position and is not blocked by the lips, thereby capturing a more complete image of the teeth and gums.

[0042] like Figure 2B As shown, when the opener 240 is disassembled from the support arm 220 and the main body 210, that is, the user removes the opener 240 from the oral photographing device 200, the user can insert the photographing part 230 connected to the support arm 220 into the user's mouth, so that the camera module in the photographing part 230 can capture images of the inside of the user's mouth.

[0043] For example, Figure 3A FIG. 1 is a structural diagram of an oral imaging device in another embodiment. Figure 3A As shown, the oral photography device 300 includes a main body 310 , a support arm 320 connected to the main body, and a photography unit 330 connected to the support arm 320 .

[0044] In some embodiments, the support arm 320 may include a positioning portion 322, which may be used to stabilize the support arm 320 of the oral photography device 300 so that the camera module can capture images of the user's oral cavity. Figure 3B As shown, when the oral camera device 300 is placed on a dental arch (e.g., the lower dental arch) and the shooting angle of the camera module of the shooting unit 330 is toward another dental arch (e.g., the upper dental arch), the support arm 320 can be stabilized by the positioning portion 322. With this structure, the distance between the camera module of the shooting unit 330 and the shooting object (e.g., the upper dental arch) can be increased, allowing the camera module to capture more oral areas in a single image, such as enabling the camera module to capture a panoramic view of the entire upper dental arch. Compared with traditional oral camera devices, the oral camera device 300 provided in the embodiment of the present application can also reduce the angle at which the user opens the mouth when shooting oral images.

[0045] For example, Figure 4A FIG. 1 is a schematic diagram of the structure of the shooting unit in one embodiment. Figure 4A As shown, the shooting unit may include a light emitting module 116 and a camera module 118 . The light emitting module 116 may include a plurality of lamps. Optionally, the plurality of lamps of the light emitting module 116 may be arranged around the camera module 118 .

[0046] The light emitting module 116 can emit visible light, for example, white light, purple light, blue light, ultraviolet light, red light, etc. Optionally, the light emitting module 116 can also emit invisible light, for example, infrared light, ultraviolet light, laser light, etc.

[0047] In some embodiments, the lamp in the light emitting module 116 can generate light in at least one of the following wavelength bands: 100nm (nanometers) to 400nm, 350nm to 500nm, 380nm to 750nm, 700nm to 2500nm, and 2500nm to 1mm (millimeter). The light emitting module 116 can be used not only for illumination, but also for providing specific wavelengths of light that are helpful for scanning or inspecting corresponding objects. For example, the purple light provided by the light emitting module 116 can be used to stimulate the fluorescence effect of dental plaque, or the infrared light provided by the light emitting module 116 can be used to detect interproximal caries and internal demineralization of teeth.

[0048] In some embodiments, the light emitting module 116 may emit light in a first wavelength band, which may be used for illumination. For example, the light emitting module 116 may emit white light for illumination.

[0049] The light-emitting module 116 can also emit light of a second wavelength band, which can be used to enhance the presentation of undesirable substances or diseased areas in the oral cavity in the image. For example, the light-emitting module 116 emits violet light or blue light to stimulate the fluorescence effect of dental plaque, and / or, the light-emitting module 116 can emit near-infrared light to detect interproximal caries and internal demineralization of teeth, and / or, the light-emitting module 116 can emit far-infrared light to detect local temperature increases caused by gingival inflammation, so that the camera module can capture thermal imaging images, and / or, the light-emitting module 116 can emit mid-infrared light to detect tooth mineral content and evaluate tooth demineralization or remineralization, and / or, the light-emitting module 116 can emit ultraviolet light to stimulate fluorescence differences in dental plaque or caries areas.

[0050] Exemplarily, the first band may include 315 to 400 nm, and the second band may include at least one of 350 to 500 nm, 700 to 2500 nm, 2500 nm to 1 mm, 100 to 400 nm, etc. The light-emitting module 116 can emit light of different bands to meet the lighting requirements of the camera module 118 and improve the image quality of the oral images taken by the oral camera device, and can also meet the needs of enhancing the presentation effect of adverse substances or diseased areas in the oral cavity in the image, enriching the oral detection function of the oral camera device and improving the performance of the oral camera device.

[0051] Optionally, the light emitting module 116 may include at least a first type of lamp and a second type of lamp, wherein the first type of lamp is configured to emit light in a first wavelength band, and the second type of lamp is configured to emit light in a second wavelength band. Furthermore, the second type of lamp may include one or more subtypes. For second wavelength bands of different wavelength ranges, lamps of different subtypes may be configured to emit light in corresponding wavelength ranges. For example, a lamp may be configured to emit light in the range of 350 to 500 nm, a lamp may be configured to emit light in the range of 700 to 2500 nm, a lamp may be configured to emit light in the range of 100 to 400 nm, and the like, without limitation herein.

[0052] It should be noted that a sub-type of lamp can also emit light in a second band of multiple different wavelength ranges. For example, an infrared lamp can be used to emit near-infrared light of 700 to 2500 nm, and can also be used to emit mid-infrared light or far-infrared light of 2500 nm to 1 mm.

[0053] In some embodiments, the oral shooting device supports a first shooting mode and a second shooting mode. In the first shooting mode and the second shooting mode, the camera module 118 is in different light environments, and the light-emitting module 116 illuminates the shooting object in the first shooting mode and / or the second shooting mode. For example, in the first shooting mode, the light-emitting module 116 does not emit light, and in the second shooting mode, the light-emitting module 116 emits light of the second band; or, in the first shooting mode, the light-emitting module 116 emits light of the first band, and in the second shooting mode, the light-emitting module 116 emits light of the second band; or, in the first shooting mode, the light-emitting module 116 emits light of the first band, and in the second shooting mode, the light-emitting module 116 does not emit light, etc., which is not limited here.

[0054] In some embodiments, the camera module 118 may include a wide-angle camera, and the FOV (Field of View) corresponding to the wide-angle camera may be greater than or equal to 140°. For example, the FOV corresponding to the wide-angle camera may be 140°, 145°, 150°, 157°, 160°, 163°, 170°, 180°, etc., but not limited thereto, so that when the oral camera device is inserted deep into the user's oral cavity, the camera module 118 of the oral camera device can capture a panoramic image of the dental arch in a single image. Figure 3B For example, when the oral camera device 300 is placed on a dental arch (such as the lower dental arch) and the shooting angle of the camera module 118 is toward another dental arch (such as the upper dental arch), the wide-angle camera can more easily capture a panoramic image of the entire dental arch or occlusal surface at a normal mouth opening angle.

[0055] Furthermore, when the camera module 118 is used to capture the occlusal surface, the area ratio of the occlusal surface in the oral image captured by the wide-angle camera is greater than the target ratio threshold; this area ratio refers to the ratio of the area of ​​the occlusal surface included in the oral image to the complete occlusal surface of the user's oral cavity. The area ratio of the occlusal surface captured by the wide-angle camera is greater than the target ratio threshold, indicating that the occlusal surface captured by the wide-angle camera is relatively complete. The user can obtain a relatively complete image of the occlusal surface through a single shooting operation without having to adjust the shooting position and / or shooting angle multiple times, thereby improving the ease of use of the oral photography device. The occlusal surface captured by the wide-angle camera is relatively complete, reducing the number of required shots. At the same time, the panoramic image based on the occlusal surface is also conducive to subsequent oral condition analysis.

[0056] Optionally, the camera module 118 may include a fixed-focus camera, which reduces calibration time, enables faster shooting response, and shortens shooting wait time. Furthermore, when the camera is a fixed-focus camera and the FOV is determined, the shooting information corresponding to a specific object can also be relatively certain, making it easier to pre-set shooting parameters, and the entire product hardware architecture and control logic are more simplified and practical.

[0057] Figure 4B FIG. 1 is a structural block diagram of an oral imaging device in one embodiment. Figure 4B As shown, the oral imaging device may further include a controller 120, which may be connected to the light emitting module 116 and the camera module 118. The controller 120 may control the operation of the light emitting module 116 and the camera module 118.

[0058] In the related art, when the oral camera device switches from a first shooting mode to a second shooting mode, the light module 116 needs to turn off the light source that was working in the first shooting mode and / or needs to turn on the light source that was working in the second shooting mode. The entire process of turning off the light source and / or turning on the light source is relatively slow. During the process of turning off the light source and / or turning on the light source, the light environment in which the camera module 118 is located is unstable. If the camera module 118 is immediately controlled to capture images when switching from the first shooting mode to the second shooting mode, it will cause the camera module 118 to capture images in an unstable light environment, affecting the quality of the images captured by the camera module 118 in the second shooting mode.

[0059] In the embodiment of the present application, the controller 120 controls the camera module 118 to capture a first image of the subject in a first capture mode in response to a capture instruction. The controller 120 switches from the first capture mode to a second capture mode and, after a first duration, controls the camera module 118 to capture a second image of the subject. By allowing sufficient time for the light module to turn on and / or off, the camera module is in a relatively stable lighting environment when capturing the second image, thereby improving the quality of the oral images captured by the intraoral camera.

[0060] like Figure 5 As shown, in one embodiment, a shooting control method of an oral shooting device is provided, which can be applied to the above-mentioned oral shooting device. The method may include the following steps:

[0061] Step 510 : In response to a shooting instruction, in a first shooting mode, controlling the camera module to capture a first image of the object.

[0062] The oral shooting device supports a first shooting mode and a second shooting mode. In the first shooting mode and the second shooting mode, the camera module is in different light environments, and the light-emitting module illuminates the shooting object in the first shooting mode and / or the second shooting mode, so that the shooting device can capture different oral images in different light environments, which can better analyze the user's oral health.

[0063] In some embodiments, in the first shooting mode, the light emitting module does not emit light, and in the second shooting mode, the light emitting module emits light; in the first shooting mode, the light emitting module emits light, and in the second shooting mode, the light emitting module does not emit light; or, in the first shooting mode and the second shooting mode, the light emitting module emits light of different bands.

[0064] As an embodiment, in the first shooting mode, the light emitting module does not emit light, the light emitting module does not work, and the camera module can be in a natural light environment; in the second shooting mode, the light emitting module emits light, and the camera module can be in a light environment generated by the light emitted by the light emitting module.

[0065] As an embodiment, in the first shooting mode, the light emitting module emits light, and the camera module can be in a light environment generated by the light emitted by the light emitting module; in the second shooting mode, the light emitting module does not emit light, the light emitting module does not work, and the camera module can be in a natural light environment.

[0066] As an embodiment, in the first shooting mode and the second shooting mode, the light emitting module emits light of different wavelengths, and the light of different wavelengths corresponds to different colors and / or different functions. In the first shooting mode and the second shooting mode, the camera module is respectively in different light environments generated by the light of the different wavelengths emitted by the light emitting module. For example, in the first shooting mode, if the light emitting module emits white light, the camera module is in a white light environment; in the second shooting mode, if the light emitting module emits purple light, the camera module is in a purple light environment, etc., but the present invention is not limited thereto.

[0067] Optionally, the oral photography device can support the user to select any one of the three lighting modes mentioned above. For example, the user can choose a lighting mode in which the light-emitting module does not emit light in the first shooting mode and emits light in the second shooting mode; or, the user can choose a lighting mode in which the light-emitting module emits light in the first shooting mode and does not emit light in the second shooting mode; or, the user can choose a lighting mode in which the light-emitting module emits light of different bands in the first shooting mode and the second shooting mode, respectively.

[0068] For example, users can make selections using buttons on the oral camera, or through a terminal device connected to the oral camera (such as a mobile phone, central control device, etc.). This can meet the different needs of users and improve the flexibility and ease of use of the oral camera.

[0069] In some embodiments, in a first shooting mode, the camera module is in a white light environment or a natural light environment, and in a second shooting mode, the camera module is in a functional light environment; or, in the first shooting mode, the camera module is in a functional light environment, and in the second shooting mode, the camera module is in a white light environment or a natural light environment; wherein, the functional light in the functional light environment is emitted by the light-emitting module, and the functional light is used to enhance the presentation effect of adverse substances or diseased areas in the oral cavity in the image.

[0070] One of the first and second shooting modes may be a mode for capturing color images of a normal oral cavity. The corresponding light environment for this mode may be a white light environment or a natural light environment. In this white light environment or natural light environment, the camera module may capture color images of a normal oral cavity. The other of the first and second shooting modes may be a mode for capturing images used to detect oral problems or oral diseases in the oral cavity. The corresponding light environment for this other mode may be a functional light environment. In this other mode, the light-emitting module emits functional light that can enhance the presentation of undesirable substances or diseased areas in the oral cavity in the image. In this functional light environment, the camera module may capture images used to detect oral problems or oral diseases in the oral cavity.

[0071] By combining the mode of taking color images of ordinary oral cavity with the mode of taking images used to detect oral problems or oral diseases in the oral cavity, the camera module can capture oral images in different modes during a single image capture process, enriching the image types captured by the camera module and helping to improve the accuracy of subsequent oral analysis and detection using images.

[0072] In some embodiments, the first shooting mode may be a mode for shooting a color image of an ordinary oral cavity. In some embodiments, in the first shooting mode, the oral shooting device may shoot a color image of an ordinary oral cavity. In the first shooting mode, the light emitting module may emit light of a first band, and the light of the first band may be used for illumination, so that the camera module can capture a color image of the oral cavity.

[0073] The second shooting mode may be a mode for shooting images for detecting oral problems or oral diseases present in the oral cavity. In the second shooting mode, the oral shooting device may shoot images for detecting oral problems or oral diseases present in the oral cavity. In the second shooting mode, the light-emitting module may emit at least light of a second wavelength band, and the light of the second wavelength band may be used to enhance the presentation of adverse substances or diseased areas in the oral cavity in the image, so that the camera module may capture images of fluorescent display that excites dental plaque, and / or may shoot thermal imaging images (for detecting local temperature increases caused by gingival inflammation), and / or may shoot images obtained using laser speckle imaging (for detecting changes in gingival blood flow), and other images, so as to use these images to better analyze oral problems or oral diseases present in the oral cavity.

[0074] The lighting parameters corresponding to the first and second shooting modes of the lighting module, as well as the shooting parameters corresponding to the first and second shooting modes of the camera module, can be pre-set. The lighting parameters may refer to parameters used to control the light emitted by the lighting module, which affect the intensity of the light emitted by the lighting module. The shooting parameters may refer to parameters used to control the image captured by the camera module, which affect the brightness of the image captured by the camera module.

[0075] Optionally, the lighting parameters corresponding to the light-emitting module include, but are not limited to, at least one of the following parameters: lighting power, lighting brightness, and the number of lighting lamps.

[0076] The luminous power refers to the operating power of the light-emitting module. The higher the power corresponding to the light-emitting module, the greater the intensity of the light emitted by the light-emitting module.

[0077] Luminous brightness refers to the brightness of light emitted by a light-emitting module. The greater the luminous brightness corresponding to the light-emitting module, the greater the intensity of the light emitted by the light-emitting module.

[0078] The number of illuminated lamps refers to the number of lamps that are lit in the light emitting module. The greater the number of illuminated lamps in the light emitting module, the greater the intensity of light emitted by the light emitting module.

[0079] In some embodiments, the shooting parameters corresponding to the camera module include, but are not limited to, one or more of the following parameters: exposure time, exposure gain, exposure compensation, exposure expectation, and sensitivity.

[0080] Exposure duration refers to the time it takes for light to enter the image sensor when the camera module is capturing an image. This is also the interval between the shutter opening and closing. The exposure duration of the camera module affects the brightness of the image. The longer the exposure duration, the more light enters the camera module, resulting in a brighter image.

[0081] Exposure gain refers to the amplification factor of the signal output by the image sensor. Amplifying the signal output by the image sensor can increase the brightness of the image. The greater the exposure gain corresponding to the camera module, the brighter the image.

[0082] Exposure compensation refers to adjusting the image's exposure and brightness by changing the exposure value corresponding to the camera module. When the exposure compensation increases, the image's exposure increases, improving its brightness. When the exposure compensation decreases, the image's exposure decreases, reducing its brightness.

[0083] The exposure expectation defines the brightness level that the camera module expects to achieve. The greater the exposure expectation corresponding to the camera module, the brighter the image.

[0084] Sensitivity is an important parameter to measure the sensitivity of its photosensitive element to light. The higher the sensitivity, the stronger the ability to capture light.

[0085] In some embodiments, the lighting parameters corresponding to the lighting module in the first shooting mode are different from the lighting parameters corresponding to the lighting module in the second shooting mode; and / or the shooting parameters corresponding to the camera module in the first shooting mode are different from the shooting parameters corresponding to the camera module in the second shooting mode. By setting different lighting parameters and / or shooting parameters in the first shooting mode and the second shooting mode, the camera module can capture oral images that meet image quality requirements in both the first shooting mode and the second shooting mode, thereby improving the performance of the oral photography device.

[0086] Each time the oral camera captures an image, the camera module can be controlled to capture a first image of the subject in a first capture mode and a second image of the subject in a second capture mode. The subject refers to a main object within the field of view of the camera module. In an embodiment of the present application, the subject may be tissue or structure in the oral cavity (such as teeth, gums, oral mucosa, etc.). For example, when the oral camera is used to capture an image of the upper occlusal surface of the oral cavity (the occlusal surface refers to the tooth surface where the teeth occlude), the upper occlusal surface of the teeth may be the subject. Through a single image capture process, oral images in two capture modes can be captured, thereby improving the ease of use of the oral camera.

[0087] When the intraoral camera receives a capture instruction, it can respond to the capture instruction and control the camera module to capture a first image of the subject in a first capture mode. The capture instruction may be a command for triggering the intraoral camera to capture. Optionally, upon receiving the capture instruction, the intraoral camera operates in the first capture mode and controls the light-emitting module to emit light corresponding to the first capture mode. Alternatively, the intraoral camera operates in the first capture mode before receiving the capture instruction and, upon receiving the capture instruction, directly controls the camera module to capture the first image corresponding to the first capture mode.

[0088] In some embodiments, the shooting instruction is generated when a triggered shooting operation is detected; and / or the shooting instruction is generated when it is detected that the image captured by the camera module meets a preset condition.

[0089] As an embodiment, a shooting operation for triggering the camera module to capture images can be pre-set. If the oral camera device detects the triggered shooting operation, it can respond to the shooting operation and generate a shooting instruction. According to the shooting instruction, the camera module can be controlled to capture images in the first shooting mode and the second shooting mode respectively.

[0090] The capture operation may include, but is not limited to, one or more of the following: triggering a physical button, a gesture, or a voice command. For example, the intraoral camera device may include a capture button, and the user triggers the capture operation by pressing the capture button. For another example, the capture operation may be triggered when the intraoral camera device is held still for a target time. For another example, the intraoral camera device may capture and recognize a voice command such as "capture" through a sound acquisition device (such as a microphone) to trigger the capture operation.

[0091] With this implementation, the user can trigger the shooting operation according to actual needs, thereby triggering the oral shooting device to shoot images, meeting the user's usage needs and improving the convenience of using the oral shooting device.

[0092] As another embodiment, when the oral shooting device is started, the camera module can be continuously in the on state, and the camera module can continuously collect images. It can detect whether the image collected by the camera module meets the preset conditions. When it is detected that the image collected by the camera module meets the preset conditions, a shooting instruction is generated, and the camera module is controlled to capture images in the first shooting mode and the second shooting mode according to the shooting instruction.

[0093] The preset conditions may refer to the conditions that can trigger the oral imaging device to perform the image capturing process. The preset conditions can be set according to the actual oral imaging requirements. Optionally, the preset conditions may include but are not limited to one or more of the following conditions:

[0094] (1) The image captured by the camera module contains a preset shooting object, for example, teeth are recognized from the image captured by the camera module.

[0095] (2) The offset information of the continuous multiple frames of images captured by the camera module is less than the preset offset value.

[0096] The image offset information can be used to characterize the deviation between two adjacent frames of images. If the offset information of multiple consecutive frames of images captured by the camera module is less than the preset offset value, it means that the camera module is very stable and has not moved, indicating that the camera module has been aligned with the subject, and a shooting instruction can be generated.

[0097] For example, the offset information of the image can be calculated using an optical flow method, a block matching algorithm (Block Matching Algorithm, BMA), a feature point matching algorithm, and the like, which are not limited here.

[0098] (3) According to the image captured by the camera module, it is recognized that the camera module is in an intra-oral state, where the intra-oral state means that the camera module is inside the user's oral cavity.

[0099] With this implementation, the oral photography device actively captures images when it detects that the image captured by the camera module meets preset conditions, thereby improving the intelligence of the oral photography device and increasing the ease of use of the oral photography device without requiring user operation.

[0100] Step 520 , switching from the first shooting mode to the second shooting mode, and controlling the camera module to capture a second image of the subject after a first period of time.

[0101] When the oral shooting device switches from a first shooting mode to a second shooting mode, the light-emitting module needs to turn off the light source working in the first shooting mode and / or needs to turn on the light source working in the second shooting mode. In the process of turning off the light source and / or turning on the light source, the light environment in which the camera module is located is unstable. If the camera module is immediately controlled to capture images when switching from the first shooting mode to the second shooting mode, the camera module will capture images in an unstable light environment, affecting the image quality captured by the camera module in the second shooting mode.

[0102] For example, when the light-emitting module emits light of different wavelengths in the first shooting mode and the second shooting mode, respectively, when the oral shooting device switches from the first shooting mode to the second shooting mode, the light-emitting module needs to turn off the light source working in the first shooting mode and turn on the light source working in the second shooting mode. The light source switching process is slow. Due to light scattering, the light emitted by the light-emitting module in the first shooting mode will still have residual light when switching to the second shooting mode. If the camera module is immediately controlled to capture images when switching from the first shooting mode to the second shooting mode, it will be affected by the residual image and light source interference in the first shooting mode. In particular, for the camera module with a rolling shutter sensor, there is a certain time lag when the rolling shutter sensor scans the image line by line. As a result, when different light sources are switched, some lines in the image may be affected by the previous light source, affecting the image quality captured by the camera module in the second shooting mode.

[0103] For example, when the light-emitting module does not emit light in the first shooting mode but emits light in the second shooting mode, when the oral shooting device switches from the first shooting mode to the second shooting mode, the light-emitting module needs to turn on the light source working in the second shooting mode. Since it takes a process for the light source to light up and stabilize the brightness, if the camera module is immediately controlled to capture images when switching from the first shooting mode to the second shooting mode, it will cause the camera module to capture images in an unstable light environment, affecting the image quality captured by the camera module in the second shooting mode.

[0104] Furthermore, the shooting parameters corresponding to the camera module in the first shooting mode are different from the shooting parameters corresponding to the camera module in the second shooting mode. When the oral camera device switches from the first shooting mode to the second shooting mode, the shooting parameters of the camera module need to be adjusted accordingly. If the camera module is immediately controlled to capture an image upon switching to the second shooting mode, the image quality of the second image captured by the camera module in the second shooting mode will be poor due to the improper adjustment of the shooting parameters of the camera module.

[0105] In an embodiment of the present application, after the oral camera device switches from the first shooting mode to the second shooting mode, the camera module is not immediately controlled to shoot an image, but after waiting for a first time period, the camera module is controlled to capture a second image of the object. By delaying the control of the camera module to capture an image, sufficient time is reserved for the light module to turn on and / or turn off the light source, so that the camera module is in a relatively stable light environment when capturing the second image. When the light module emits light in the first shooting mode, the residual light of the first shooting mode will dissipate within the first time period, thereby preventing the light of the first shooting mode from affecting the second image captured by the camera module, and sufficient time is reserved for the camera module to adjust the shooting parameters, ensuring that the camera module completes the adjustment of the shooting parameters within the first time period, thereby improving the image quality of the second image captured by the camera module.

[0106] In some embodiments, the first duration can be a pre-set fixed duration, such as 2 seconds, 3 seconds, etc. The first duration should not be set too short or too long. If the first duration is too short, the process of turning on and / or turning off the light source by the light-emitting module may not be completed, the light environment may not be stable, or the camera module may not complete the adjustment of the shooting parameters, resulting in the image quality of the second image still being poor. If the first duration is too long, the camera module may not capture the second image for a long time, causing trouble to the user, and the second shooting mode may be running for too long, resulting in unnecessary power consumption loss.

[0107] Optionally, the first duration can be set according to the light-emitting parameters corresponding to the first shooting mode of the light-emitting module. For example, if the light emitted by the light-emitting module according to the light-emitting parameters corresponding to the first shooting mode is brighter, the first duration can be set to a longer time. If the light emitted by the light-emitting module according to the light-emitting parameters corresponding to the first shooting mode is darker, the first duration can be set to a shorter time, thereby ensuring that the light environment can be in a relatively stable state at the end of the first duration. For example, the residual light of the first shooting mode will be completely dissipated within the first duration.

[0108] In an embodiment of the present application, when switching from the first shooting mode to the second shooting mode, the delay control camera module captures the second image, and the residual light of the first shooting mode will dissipate within the first time period, thereby avoiding the influence of the light of the first shooting mode on the second image, and improving the image quality of the oral image captured by the oral shooting equipment, thereby further improving the accuracy of oral condition assessment using the oral image.

[0109] In some embodiments, the working states of the light emitting module are different in the first shooting mode and the second shooting mode (for example, it does not work in one shooting mode and works in another shooting mode, or different light sources are used to emit light, etc.). Therefore, the first shooting mode and the second shooting mode may have different mode characteristics, respectively, and running the first shooting mode and running the second shooting mode have different effects on the oral shooting equipment.

[0110] Optionally, the operating power consumption corresponding to the first shooting mode is less than the operating power consumption corresponding to the second shooting mode; and / or the luminous power of the light-emitting module in the first shooting mode is less than the luminous power of the light-emitting module in the second shooting mode; and / or the operating current of the light-emitting module in the first shooting mode is less than the operating current of the light-emitting module in the second shooting mode; and / or the temperature rise rate of the oral shooting device in the first shooting mode is less than the temperature rise rate of the oral shooting device in the second shooting mode; and / or the device temperature of the oral shooting device in the first shooting mode is less than the device temperature of the oral shooting device in the second shooting mode.

[0111] In some embodiments, the light-emitting module does not emit light in the first shooting mode, but does emit light in the second shooting mode. That is, the light-emitting module does not operate in the first shooting mode, but operates in the second shooting mode. Therefore, the operating power consumption corresponding to the second shooting mode is greater than the operating power consumption corresponding to the first shooting mode; the temperature rise rate of the intraoral camera in the second shooting mode is greater than the temperature rise rate of the intraoral camera in the first shooting mode; and the device temperature of the intraoral camera in the second shooting mode is greater than the device temperature of the intraoral camera in the first shooting mode.

[0112] In some embodiments, in the first shooting mode, the light emitting module emits light in the first wavelength band. Furthermore, in the first shooting mode, the light emitting module does not emit light in the second wavelength band. For example, the light emitting module may include a first type of lamp and a second type of lamp, the first type of lamp being configured to emit light in the first wavelength band and the second type of lamp being configured to emit light in the second wavelength band. In the first shooting mode, the first type of lamp may be in a lit state and the second type of lamp may be in a non-lit state.

[0113] In the second imaging mode, the light-emitting module emits at least light in the second wavelength band. Therefore, the light-emitting module illuminates at least the second type of lamp. The operating current and / or luminous power required to illuminate the second type of lamp is greater than the operating current and / or luminous power required to illuminate the first type of lamp. Therefore, the second imaging mode generates higher operating power consumption, and the second type of lamp generates more heat when illuminated. This causes the temperature of the oral imaging device to rise more rapidly in the second imaging mode, resulting in a higher device temperature.

[0114] For example, the light emitting module includes a white light and a purple light. In the second shooting mode, the purple light emits purple light. The working current of the purple light is about 300mA (milliamperes), and the temperature rises quickly (such as causing the oral environment temperature to rise by 3°C per second).

[0115] Therefore, the operating power consumption corresponding to the second shooting mode is greater than the operating power consumption corresponding to the first shooting mode; the temperature increase rate of the oral shooting equipment in the second shooting mode is greater than the temperature increase rate of the oral shooting equipment in the first shooting mode; the device temperature of the oral shooting equipment in the second shooting mode is greater than the device temperature of the oral shooting equipment in the first shooting mode.

[0116] The temperature rise rate of the intraoral camera device can refer to the temperature rise rate of the intraoral camera device itself, or the temperature rise rate of the environment in which the intraoral camera device is located due to the heat generated by the intraoral camera device. The device temperature can refer to the housing temperature of the intraoral camera device and / or the temperature of components within the intraoral camera device.

[0117] In an embodiment of the present application, the oral camera device first runs the first shooting mode, and after the camera module successfully captures the first image, it switches from the first shooting mode to the second shooting mode. This can prevent the oral camera device from being in the second shooting mode for a long time, which may lead to problems such as excessive power consumption, rapid temperature increase, and severe heat generation. It reduces the power consumption of the oral camera device, improves the battery life of the oral camera device, and maintains the device temperature of the oral camera device within a safe temperature value (for example, 50°C, 54°C, 60°C, etc.), thereby ensuring the service life of various components inside the oral camera device and avoiding the main body temperature being too high, causing discomfort to the user.

[0118] Furthermore, when the camera module is in the second shooting mode and captures the second image of the subject, the oral shooting device can switch back to the first shooting mode from the second shooting mode, further avoiding the oral shooting device being in the second shooting mode for a long time, resulting in problems such as excessive power consumption, rapid temperature increase, and severe heat generation.

[0119] In some embodiments, the oral photography device operates in the first photography mode when receiving the photography instruction. Figure 6 As shown, a method for controlling an oral photography device is provided, which may include the following steps:

[0120] Step 602 : In response to the shooting instruction, control the oral shooting device to a first shooting mode, and after a second time period, control the camera module to capture a first image of the object.

[0121] When the intraoral camera receives a capture instruction, it operates in a first capture mode and can control the light module to emit light corresponding to the first capture mode, for example, the light module can be controlled to emit light in a first wavelength band. Since the light module activates the light source corresponding to the first wavelength band, it needs to wait a certain period of time for the light source to stabilize. To ensure that the camera module captures images in a stable lighting environment, the camera module can be controlled to capture the first image of the subject after waiting for a second period of time. This ensures that the camera module captures the first image in a stable lighting environment, thereby improving the image quality of the first image.

[0122] In some embodiments, the second duration can be a pre-set fixed duration, such as 1 second, 2 seconds, etc. The second duration should not be set too short or too long. If the second duration is too short, the camera module may shoot when the light source is not stable, resulting in poor image quality of the first image. If the second duration is too long, the overall image capture process may be too long and cause unnecessary power consumption loss.

[0123] Step 604 , switching from the first shooting mode to the second shooting mode, and controlling the camera module to capture a second image of the subject after a first period of time.

[0124] The description of step 604 can refer to the relevant descriptions in the above embodiments, and will not be repeated here.

[0125] In an embodiment of the present application, the oral camera device starts to run the first shooting mode only when it obtains the shooting instruction, which can reduce the power consumption of the oral camera device. After the oral camera device runs the first shooting mode for a second period of time, the camera module is controlled to capture the first image of the shooting object, and sufficient time is reserved for the light-emitting module to turn on the light source corresponding to the first shooting mode, thereby ensuring that the camera module captures the first image in a stable light environment, thereby improving the image quality of the first image. Moreover, after switching from the first shooting mode to the second shooting mode, after waiting for the first period of time, the camera module is controlled to capture the second image of the shooting object, and sufficient time is reserved for the light-emitting module to turn off the light source corresponding to the first shooting mode and turn on the light source corresponding to the second shooting mode, thereby ensuring that the camera module captures the second image in a stable light environment, thereby improving the image quality of the second image.

[0126] In some embodiments, the oral photography device first runs the first photography mode before obtaining the photography instruction, and directly controls the camera module to capture the first image corresponding to the first photography mode when the photography instruction is obtained. Figure 7 As shown, a method for controlling an oral photography device is provided, which may include the following steps:

[0127] Step 702: When the oral cavity photographing device is started, control the oral cavity photographing device to be in a first photographing mode.

[0128] When the oral camera device is started, the oral camera device can be set to run in the first shooting mode by default. Since the operating power consumption corresponding to the first shooting mode is less than the operating power consumption corresponding to the second shooting mode, the power consumption loss of the oral camera device can be saved.

[0129] In some embodiments, when the oral shooting device is started, the entrance state corresponding to the camera module can be detected. The entrance state corresponding to the camera module can be used to indicate whether the camera module is outside the oral cavity or inside the oral cavity. The entrance state may include an extraoral state or an intraoral state, wherein the extraoral state refers to the state in which the camera module is located outside the oral cavity, and the intraoral state refers to the state in which the camera module is located inside the oral cavity.

[0130] In one embodiment, the entrance state corresponding to the camera module can be identified and detected based on images captured by the camera module. The oral camera device can recognize the image content of the image captured by the camera module and determine whether the camera module is in the intraoral state or the extraoral state based on the recognized image content, thereby obtaining the entrance state corresponding to the camera module.

[0131] As another embodiment, the oral photography device may include an entrance sensor, and the entrance state corresponding to the camera module may be determined based on information obtained by the entrance sensor.

[0132] For example, the inlet sensor may include, but is not limited to, a pressure sensor. For example, if the inlet sensor is a pressure sensor, the oral imaging device may obtain a pressure value collected by the pressure sensor. This pressure value is used to represent the magnitude of the force acting on the imaging unit. If the pressure value is greater than or equal to a pressure threshold, it can be determined that the camera module is in the intraoral state. If the pressure value is less than the pressure threshold, it can be determined that the camera module is in the extraoral state.

[0133] For example, an oral imaging device is used as Figure 2A In the product structure shown, the entrance sensor may include a sensor that can be used to detect the connection status of the opener 240 and the main body 210. For example, the entrance sensor may include a Hall sensor, which can be set at the connection position corresponding to the opener 240 and the main body 210 (such as set at one end of the opener 240 connected to the main body 210, or set at the position of the main body 210 for connecting the opener 240). The Hall sensor can be used to detect the connection status of the opener 240 and the main body 210.

[0134] When the oral camera device is activated, if it is detected that the camera module is in the intraoral state, the oral camera device can be controlled to operate in a first shooting mode. When the camera module is in the intraoral state, it is likely that the oral camera device will need to take oral pictures, and the oral camera device can be controlled to operate in the first shooting mode, controlling the light emitting module to emit light in the first wavelength band.

[0135] Optionally, when the oral camera device is started, if it is detected that the camera module is in the extraoral state, the oral camera device can be controlled not to run the first shooting mode or the second shooting mode first, that is, the light-emitting module can be controlled not to illuminate first, further reducing power consumption waste.

[0136] Step 704 : In response to the shooting instruction, in a first shooting mode, control the camera module to capture a first image of the object.

[0137] Upon receiving the capture instruction, the intraoral camera controls the camera module to capture a first image of the subject in the first capture mode. Because the intraoral camera was already operating in the first capture mode before receiving the capture instruction, the camera module is already in a stable lighting environment corresponding to the first capture mode when the capture instruction is received. Therefore, the camera module can be directly controlled to capture the first image of the subject, reducing the waiting time for the light source to stabilize and thereby shortening the duration of the entire image capture process.

[0138] Step 706 , switching from the first shooting mode to the second shooting mode, and controlling the camera module to capture a second image of the subject after a first period of time.

[0139] The description of step 706 can refer to the relevant descriptions in the above embodiments, and will not be repeated here.

[0140] Step 708: Switch from the second shooting mode back to the first shooting mode.

[0141] In some embodiments, the second shooting mode may be switched back to the first shooting mode when a target switching condition is satisfied. The target switching condition refers to a condition that triggers switching back to the first shooting mode from the second shooting mode.

[0142] Optionally, the target switching condition may include but is not limited to one or more of the following conditions:

[0143] (1) The running time of the second shooting mode reaches the time threshold.

[0144] The oral photography device can record the running time in the second shooting mode and determine whether the running time in the second shooting mode reaches the time threshold. If the running time in the second shooting mode reaches the time threshold, it means that the second shooting mode has been in place for a long time, and the second shooting mode can be switched back to the first shooting mode.

[0145] (2) According to the second image captured by the camera module in the second shooting mode, the harmful substance or diseased area in the oral cavity is identified.

[0146] In the second shooting mode, the light emitting module can emit light of a second wavelength band for enhancing the presentation of undesirable substances or diseased areas in the oral cavity in the image. The oral shooting device can obtain the second image captured by the camera module in the second shooting mode and recognize the second image. If undesirable substances or diseased areas in the oral cavity are recognized in the second image, it means that a relatively valuable second image has been captured (which can be used to analyze the health of the user's oral cavity), and the second shooting mode can be switched back to the first shooting mode.

[0147] (3) A triggered mode switching operation is detected.

[0148] The user can perform a mode switching operation according to actual needs, thereby triggering the oral camera to switch from the second shooting mode back to the first shooting mode. If the oral camera detects the triggered mode switching operation, it can respond to the mode switching operation and switch from the second shooting mode back to the first shooting mode.

[0149] Mode switching operations may include, but are not limited to, one or more of the following: triggering a physical button, a gesture, or a voice command. For example, the intraoral camera may include a mode switch button, and the user triggers the mode switch operation by pressing the mode switch button. For another example, the intraoral camera may be configured to trigger the mode switch operation by shaking the intraoral camera twice. For another example, the intraoral camera may trigger the mode switch operation by capturing and recognizing a voice command such as "switch mode" through a sound collection device (e.g., a microphone).

[0150] (4) The number of second images captured by the camera module in the second shooting mode is greater than or equal to the number threshold.

[0151] The oral imaging device may count the number of second images captured by the camera module in the second imaging mode and determine whether the number of images is greater than or equal to a threshold value. If the number of second images captured by the camera module in the second imaging mode is greater than or equal to the threshold value, it indicates that the camera module has captured sufficient second images in the second imaging mode for oral analysis and testing, and the second imaging mode may be switched back to the first imaging mode.

[0152] The quantity threshold can be set according to actual needs. For example, the quantity threshold can be 1, 3, 6, etc., but is not limited thereto.

[0153] (5) The remaining power of the oral imaging device is lower than the power threshold.

[0154] After the camera module successfully captures the second image corresponding to the second shooting mode, if the remaining power of the oral shooting device is lower than the power threshold, it means that the battery life of the oral shooting device is insufficient. Since the operating power consumption of the second shooting mode is relatively high, the oral shooting device can switch from the second shooting mode back to the first shooting mode with lower operating power consumption, thereby reducing power consumption and improving the battery life of the oral shooting device.

[0155] (6) The device temperature of the oral imaging device is greater than the temperature threshold.

[0156] After the camera module successfully captures the second image corresponding to the second shooting mode, if the device temperature of the oral shooting device is greater than the temperature threshold, it means that the device temperature of the oral shooting device is high. Since the temperature rises faster in the second shooting mode and the heat is obvious, the oral shooting device can be switched from the second shooting mode back to the first shooting mode with a lower temperature rise rate, thereby reducing the device temperature of the oral shooting device, ensuring the service life of various components inside the oral shooting device, and avoiding the main body temperature being too high, causing discomfort to the user.

[0157] Optionally, the device temperature of the oral photography device can be acquired through a temperature sensor or the like.

[0158] In the above-mentioned embodiment, when the target switching conditions are met, switching back from the second shooting mode to the first shooting mode can improve the flexibility of mode switching and avoid the oral shooting equipment being in the second shooting mode for a long time, resulting in problems such as excessive power consumption, rapid temperature increase and severe heat generation.

[0159] In an embodiment of the present application, when the oral camera device is activated, the oral camera device defaults to operating in the first shooting mode. This allows the camera module to be in a stable light environment corresponding to the first shooting mode when a shooting instruction is received, thereby reducing the time it takes for the light source to stabilize and thus shortening the duration of the entire image capture process. Furthermore, since the operating power consumption of the first shooting mode is lower and the motion power consumption of the second shooting mode is higher, the camera module switches to the second shooting mode only after successfully capturing the first image corresponding to the first shooting mode, and then switches back to the first shooting mode after successfully capturing the second image corresponding to the second shooting mode. This can reduce the duration the oral camera device operates in the second shooting mode, thereby reducing the power consumption of the oral camera device and preventing the oral camera device from overheating.

[0160] In some embodiments, in the second shooting mode, the light emitting module may emit light in the first wavelength band and light in the second wavelength band; or, in the second shooting mode, the light emitting module only emits light in the second wavelength band.

[0161] As an embodiment, in the second shooting mode, the light-emitting module can simultaneously emit light in the first and second wavelength bands. Since the light-emitting module emits light in the second wavelength band in the second shooting mode, if the light in the second wavelength band is visible light such as purple or blue light, the color of the image captured by the camera module will be relatively strange. Therefore, in the second shooting mode, the light-emitting module can also emit light in the first wavelength band. The emitted light in the first wavelength band provides fill light, thereby improving the white balance of the second image captured by the camera module and enhancing the color rendering of the image captured by the camera module.

[0162] Furthermore, in the second shooting mode, the luminous parameters corresponding to the light of the first wavelength band are smaller than the luminous parameters corresponding to the light of the first wavelength band in the first shooting mode; and / or, in the second shooting mode, the luminous parameters corresponding to the light of the first wavelength band are smaller than the luminous parameters corresponding to the light of the second wavelength band. In the second shooting mode, the luminous parameters corresponding to the light of the first wavelength band can be set to be smaller, which can reduce the situation where the light of the first wavelength band has an adverse effect on the light of the second wavelength band, thereby reducing the image quality of the second image, thereby further ensuring the image quality of the second image captured by the camera module in the second shooting mode.

[0163] As another embodiment, in the second shooting mode, the light emitting module may only emit light of the second band, while ensuring that the camera module can capture the second image for detecting harmful substances or diseased areas in the oral cavity, reducing the operating power consumption of the second shooting mode, and avoiding the situation where light sources of different bands work together to cause severe heat.

[0164] In some embodiments, in the second shooting mode, the light emitting module can be controlled to intermittently emit light in the second wavelength band according to a preset time interval.

[0165] In the second shooting mode, the light-emitting module can intermittently emit light of the second band according to a preset time interval. Each time the light-emitting module emits light of the second band, it can last for the target emission duration. Between two adjacent emissions of light of the second band, the light-emitting module can pause for a preset time interval and not emit light of the second band.

[0166] The preset time interval and target emission duration can be set according to actual needs. For example, in the second shooting mode, the light-emitting module emits light of the second band at intervals of 1 second, and each emission of the second band light can last for 2 seconds. That is, after the light-emitting module emits light of the second band for 2 seconds, it pauses for 1 second, and then emits light of the second band for 2 seconds, pauses for 1 second, and then emits light of the second band for 2 seconds, and so on.

[0167] In an embodiment of the present application, in the second shooting mode, the light-emitting module intermittently emits light of the second band, which can avoid the continuous emission of light of the second band in the second shooting mode, resulting in excessive power consumption and severe heat generation. The operating power consumption of the oral shooting device can be reduced, the endurance of the oral shooting device can be improved, and the device temperature of the oral shooting device can be maintained below the safe value, thereby ensuring the service life of various components in the oral shooting device, and avoiding the main body temperature being too high, resulting in user discomfort, thereby improving the user experience.

[0168] In some embodiments, in order to ensure that the camera module can capture high-quality oral images in a relatively stable state, the oral camera device can also detect movement information and control the image capture of the camera module based on the movement information. Figure 8 As shown, the above method may further include the following steps:

[0169] Step 802: In response to the shooting instruction, detecting movement information of the oral shooting device within a third time period.

[0170] Step 804: If it is determined based on the movement information that the movement amplitude is greater than the amplitude threshold, a prompt message is output, where the prompt message is used to prompt that the photographed object has changed and / or that the captured image does not meet the requirements.

[0171] When the intraoral camera receives a capture instruction, movement information of the intraoral camera can be detected within a third time period. This movement information can be used to describe the movement of the intraoral camera, and further, the movement information can be used to describe the movement of the camera module. Optionally, the movement information may include, but is not limited to, movement amplitude and / or movement speed. The movement amplitude may refer to the cumulative distance moved, and the movement speed may refer to the distance moved per unit time.

[0172] The third duration may refer to the duration during which the intraoral camera detects movement information. During image capture, after switching from the first capture mode to the second capture mode, the camera module waits for the first duration before capturing the second image. This results in a relatively long capture time, making the camera module susceptible to movement. Therefore, the third duration may be greater than or equal to the first duration and less than or equal to the fourth duration, which is the duration from responding to the capture command to capturing the second image. This ensures that the intraoral camera detects movement information during both the capture of the first image corresponding to the first capture mode and the capture of the second image corresponding to the second capture mode by the camera module.

[0173] In some embodiments, the movement information is determined based on images acquired by an intraoral photography device; and / or, the intraoral photography device includes a sensor, and the movement information is determined based on information acquired by the sensor.

[0174] In one embodiment, the oral imaging device can obtain two adjacent frames of images captured by the camera module and calculate the offset information between the two adjacent frames using algorithms such as optical flow, block matching, and feature point matching. This offset information can be pixel coordinate offset values ​​and / or image coordinate offset values ​​in the image coordinate system. This offset information can be converted to the world coordinate system to obtain the movement information of the camera module.

[0175] As another embodiment, the oral photography device may be provided with a speed sensor and / or a posture sensor, etc., and the movement information of the camera module may be determined based on the sensor data collected by the speed sensor and / or the posture sensor, etc.

[0176] Furthermore, the motion information determined based on the image and the motion information determined based on the sensor data may be fused to obtain the final motion information of the camera module, thereby improving the accuracy of detecting the motion information.

[0177] The oral imaging device can determine whether the movement amplitude is greater than an amplitude threshold based on the movement information. The amplitude threshold can be set according to actual needs. Optionally, the amplitude threshold can be set based on the anti-shake capability of the camera module. The amplitude threshold can accommodate the jitter generated by the camera module when capturing images and ensure that the images captured by the camera module in the first shooting mode and the second shooting mode correspond to substantially the same subject.

[0178] If the movement amplitude exceeds the amplitude threshold, it indicates that the camera module has moved significantly in a short period of time. This may cause the first image captured by the camera module in the first shooting mode to correspond to a different subject than the second image captured in the second shooting mode, and / or cause the image captured by the camera module to contain large areas of residual image, resulting in image blur. Therefore, if the movement amplitude exceeds the amplitude threshold, a prompt message may be output to indicate that the subject has changed and / or that the captured image does not meet the requirements.

[0179] Optionally, the method of outputting prompt information may include but is not limited to one or more of displaying text and / or pictures corresponding to the prompt information through a display screen, playing audio data corresponding to the prompt information through an audio playback module, controlling the light module to flash, and controlling the vibration module to vibrate, etc., wherein the light module can be distinguished from the light-emitting module. For example, the light module can be set in the main body of the oral shooting device, or can be set in the area of ​​the support arm close to the main body, etc.

[0180] By outputting prompt information, it can be prompted that the shooting objects of the first shooting mode and the second shooting mode have changed and / or the collected images do not meet the requirements. The user can stabilize the oral shooting device according to the prompt information and then re-trigger the shooting operation to make the camera module stable in the same position for shooting, thereby ensuring the image quality of the first image and the second image collected by the camera module, and improving the accuracy of subsequent oral analysis and detection based on the first image and the second image.

[0181] If the movement amplitude is not greater than the amplitude threshold, it means that the camera module has not moved significantly, and the images captured by the camera module in the first shooting mode and the second shooting mode correspond to basically the same shooting objects. For example, the same tooth area is captured in the first shooting mode and the second shooting mode. For example, the camera module captures the same occlusal surface panoramic image in the first shooting mode and the second shooting mode. The oral shooting device can switch back to the first shooting mode from the second shooting mode after the camera module successfully captures the first image and the second image, and wait for the next image capturing process.

[0182] In an embodiment of the present application, during the process of image capture by the oral camera device, movement information can be detected, and when it is determined based on the movement information that the movement amplitude is greater than the amplitude threshold, a prompt message is output, thereby prompting that the shooting objects of the first shooting mode and the second shooting mode have changed and / or the captured images do not meet the requirements, so that the user can stabilize the oral camera device according to the prompt information and then re-trigger the shooting operation to stabilize the camera module at the same position for shooting, thereby ensuring the image quality of the first image and the second image captured by the camera module, and improving the accuracy of subsequent oral analysis and detection based on the first image and the second image.

[0183] In related technologies, when a user uses an oral camera to shoot an object in the user's mouth (such as teeth, etc.), the user is affected by various factors, such as the use position, use posture, shape of the teeth, etc. of the oral camera. The distance between the camera module on the oral camera and the object is different, resulting in different amounts of light entering the camera module when the light-emitting module is used to illuminate the object, causing the image captured by the camera module to be overexposed or too dark, affecting the image quality of the image captured by the camera module.

[0184] Therefore, in some embodiments, in order to avoid the problem of poor quality such as overexposure or darkening of the image of the object captured by the camera module due to the different distances between the camera module and the object, the lighting parameters of the lighting module and / or the shooting parameters of the camera module can be adjusted according to the shooting information, and the shooting information can be related to the distance between the camera module and the object. Figure 9 As shown, the above method may further include the following steps:

[0185] Step 902: Acquire shooting information of the oral shooting device. The shooting information is directly or indirectly related to the distance between the camera module and the shooting object.

[0186] When the intraoral camera is in operation, camera information can be obtained. This camera information is directly or indirectly related to the distance between the camera module and the subject being photographed. The camera information is directly or indirectly related to the distance between the camera module and the subject being photographed. This may mean that when the distance between the camera module and the subject changes, the camera information also changes, or that when the camera information changes, the distance between the camera module and the subject also changes. The camera information is related to the distance between the camera module and the subject being photographed, and the camera information and the distance may affect each other, or the camera information may be affected by the distance, or the distance may be affected by the camera information.

[0187] Therefore, the shooting information can be used as a reference for adjusting the lighting parameters corresponding to the lighting module and / or the shooting parameters corresponding to the camera module, and the lighting parameters corresponding to the lighting module and / or the shooting parameters corresponding to the camera module can be adjusted based on the shooting information of the oral camera device. Furthermore, the first lighting parameters corresponding to the lighting module and / or the first shooting parameters corresponding to the camera module in the first shooting mode can be adjusted based on the shooting information; and the second lighting parameters corresponding to the lighting module and / or the second shooting parameters corresponding to the camera module in the second shooting mode can be adjusted.

[0188] In some embodiments, the shooting information of the oral shooting device may include but is not limited to at least one of the following information: the oral area corresponding to the shooting object; the distance between the camera module and the shooting object; the area of ​​the oral area corresponding to the shooting object; the shooting position of the camera module in the user's mouth; the entrance state corresponding to the camera module, the entrance state including the extraoral state or the intraoral state.

[0189] The oral region corresponding to the photographed object is used to indicate the position region of the photographed object in the oral cavity. The user's oral cavity can be divided into multiple oral regions. For example, the oral cavity can be divided into multiple tooth regions and / or multiple tooth surfaces. Furthermore, the tooth regions can include but are not limited to the upper tooth region, the lower tooth region, the front tooth region, the back tooth region, etc. The tooth surfaces can include but are not limited to the occlusal surface and the tooth side surfaces. The occlusal surface is the surface where the teeth bite. The tooth side surfaces can include the inner side surface and the outer side surface. The outer side surface is the surface of the teeth close to the lips, and the inner side surface is the surface of the teeth close to the tongue, etc.

[0190] When using a camera module to shoot different oral regions, since different oral regions require different shooting distances, the distances between the camera module and different oral regions are at least partially different. For example, the distance between the camera module and the occlusal surface is different from the distance between the camera module and the outer surface. Alternatively, in some usage forms of the oral camera device, the distances between the camera module and different oral regions are different due to the influence of the shape of the dental arch. For example, when using the oral camera device as Figure 2A Taking the product structure shown as an example, when the opener 240 is connected to the main body 210, due to the shape of the dental arch, the degree of fit between different oral areas and the opener 240 is different, resulting in different distances between the camera module and different oral areas.

[0191] The distance between the camera module and the photographed object may refer to a distance value between the camera module and the photographed object, and the distance value is directly used to represent the distance between the camera module and the photographed object.

[0192] The area of ​​the oral region corresponding to the photographed subject may refer to the area of ​​the oral region where the photographed subject is located. Furthermore, the area of ​​the oral region corresponding to the photographed subject may be the area of ​​the oral region where the photographed subject is located that will appear in the image captured by the camera module. When the distance between the camera module and the photographed subject is relatively far, the camera module can capture more of the photographed subject, and therefore, the area of ​​the oral region corresponding to the photographed subject will be relatively large. When the distance between the camera module and the photographed subject is relatively close, the camera module can capture fewer subjects, and the oral region where the photographed subject is located may not be fully displayed in the image captured by the camera module. Therefore, the area of ​​the oral region corresponding to the photographed subject will be relatively small.

[0193] The shooting position of the camera module in the user's mouth, the position of the camera module relative to the user's mouth when shooting. Optionally, the shooting position can be the actual position of the camera module, for example, Figure 3B For example, if the oral camera is placed in the lower dental arch and the camera module is placed on the tongue or near the inner side of the lower teeth, the corresponding shooting position of the camera module can be the tongue or near the inner side of the lower teeth. While the subject remains unchanged, the camera module's shooting position in the user's mouth varies, and the distance from the subject varies.

[0194] Optionally, since the space inside the oral cavity is relatively small, the distance between the camera module and the photographed object is also relatively small, so the shooting position of the camera module in the user's oral cavity can also be represented by the oral cavity area where the photographed object is located. Figure 3B For example, if the camera module captures an image of the upper dental arch, the corresponding shooting position of the camera module may be the upper occlusal surface.

[0195] The entrance state corresponding to the camera module is used to indicate whether the camera module is outside the oral cavity or inside the oral cavity. The entrance state may include an extraoral state or an intraoral state, wherein the extraoral state refers to the camera module being outside the oral cavity, and the intraoral state refers to the camera module being inside the oral cavity. When the camera module is in the extraoral state and the camera module is in the intraoral state, the corresponding photographic object is different, and therefore the distance between the camera module and the photographic object will also change; or, when the camera module is in the extraoral state and the camera module is in the intraoral state, due to the limitations of the internal space of the oral cavity, the distance between the camera module and the photographic object in the extraoral state will be different from the distance between the camera module and the photographic object in the intraoral state; or, when the camera module is in the intraoral state and the extraoral state, the corresponding product form of the oral camera device is different, and therefore, the distance between the camera module and the photographic object in the extraoral state will be different from the distance between the camera module and the photographic object in the intraoral state.

[0196] By acquiring shooting information of multiple different dimensions, the accuracy and flexibility of subsequently determining the lighting parameters corresponding to the lighting module and / or the shooting parameters corresponding to the camera module based on the shooting information can be improved. Moreover, combined with the actual use scenario of the oral camera device, under different shooting information, the oral camera device can more accurately adjust the lighting parameters corresponding to the lighting module and / or the shooting parameters corresponding to the camera module, thereby improving the shooting effect of the camera module. When the oral camera device shoots different tooth surfaces and / or tooth areas, the effect of the image captured is relatively consistent, and the image will not be overexposed or too dark, which helps to improve the accuracy of the subsequent use of the image for oral condition analysis.

[0197] Step 904, determining the first parameter corresponding to the first shooting mode and the second parameter corresponding to the second shooting mode based on the shooting information; wherein the first parameter includes the first light-emitting parameter corresponding to the light-emitting module and / or the first shooting parameter corresponding to the camera module in the first shooting mode; the second parameter includes the second light-emitting parameter corresponding to the light-emitting module and / or the second shooting parameter corresponding to the camera module in the second shooting mode.

[0198] Due to the different distances between the camera module on the shooting device and the subject, when the light-emitting module is used to illuminate the subject, the light intensity emitted by the light-emitting module received by the subject is different, and the light intensity reflected by the subject to the camera module is also different, resulting in different amounts of light entering the camera module, causing the image captured by the camera module to be overexposed or too dark, affecting the image quality of the image captured by the camera module.

[0199] Therefore, in an embodiment of the present application, a first parameter corresponding to the first shooting mode and a second parameter corresponding to the second shooting mode can be determined based on shooting information related to the distance between the camera module and the object being shot. The first parameter includes a first light-emitting parameter corresponding to the light-emitting module and / or a first shooting parameter corresponding to the camera module in the first shooting mode, the first light-emitting parameter being used to control the light-emitting module to illuminate the object in the first shooting mode; the first shooting parameter being used to control the camera module to capture a first image of the object in the first shooting mode. The second parameter includes a second light-emitting parameter corresponding to the light-emitting module and / or a second shooting parameter corresponding to the camera module in the second shooting mode, the second light-emitting parameter being used to control the light-emitting module to illuminate the object in the second shooting mode; the second shooting parameter being used to control the camera module to capture a second image of the object in the second shooting mode.

[0200] The first parameter corresponding to the first shooting mode and the second parameter corresponding to the second shooting mode may have a corresponding relationship with the shooting information. Different shooting information may have corresponding first parameters and second parameters, respectively. At least some of the different shooting information may have different first parameters and / or second parameters corresponding to them. That is, for different shooting information, the corresponding first parameters and / or second parameters may be the same or different, but there are at least two (or two groups) of different shooting information with different first parameters and / or second parameters.

[0201] In some embodiments, the corresponding relationship between the first parameter and / or the second parameter and the shooting information may be a positive correlation relationship. When the shooting information increases, the first parameter and / or the second parameter may increase accordingly.

[0202] In some embodiments, the correspondence between the first parameter and / or the second parameter and the shooting information may be a discrete relationship. When the shooting information changes, the first parameter and / or the second parameter also change accordingly. One (or a group of) shooting information corresponds to one (or a group of) first parameter and / or second parameter, but the changing trend of the first parameter and / or the second parameter does not necessarily conform to a continuously increasing / decreasing trend.

[0203] It should be noted that the correspondence between the first parameter and / or the second parameter and the photographic information may be pre-set and configured based on actual needs. The correspondence may vary for different product forms of oral imaging devices. The correspondence between the first parameter and / or the second parameter and the photographic information may be determined through multiple experimental tests to ensure that the oral imaging device can capture high-quality oral images under different photographic information.

[0204] In an embodiment of the present application, the oral shooting device can dynamically adjust the first parameter corresponding to the first shooting mode and / or the second parameter corresponding to the second shooting mode according to the shooting information. Since the shooting information is directly or indirectly related to the distance between the camera module and the shooting object, the lighting parameters of the lighting module when illuminating the shooting object in the first shooting mode and / or the second shooting mode can be accurately adjusted according to the shooting information, and / or the shooting parameters of the camera module when capturing images in the first shooting mode and / or the second shooting mode can be adjusted. This can avoid the problem of poor quality such as overexposure or too dark images of the shooting object captured by the camera module due to different distances between the camera module and the shooting object, thereby improving the image quality of the oral images captured by the oral shooting device and improving the performance of the oral shooting device.

[0205] In some embodiments, the photographic information may include an oral region corresponding to the photographed subject, and the oral photographic device may determine the first parameter and / or the second parameter based on the oral region corresponding to the photographed subject. The oral region may include a tooth region and / or tooth surface, and at least two oral regions may correspond to different first parameters and / or second parameters.

[0206] Optionally, the oral area may include tooth surfaces, and the user's oral cavity may include inner side, outer side and occlusal surface, wherein the inner side may refer to the surface of the teeth close to the tongue, the outer side may refer to the surface of the teeth close to the lips, and the occlusal surface may refer to the surface of the teeth used for biting.

[0207] Optionally, the oral region may include a dental region, and the user's oral cavity may include one or more of a front teeth region and a back teeth region.

[0208] For example, Figure 10A FIG. 1 is a schematic diagram of the oral cavity region in one embodiment. Figure 10A As shown, the outer surface may include the outer surface of the front teeth 1002 and the outer surface of the back teeth. Further, the outer surface of the back teeth includes the right outer surface of the back teeth 1004 (from the user's perspective, the right outer surface of the back teeth 1004 is located on the left side of the mouth) and the left outer surface of the back teeth 1006 (from the user's perspective, the left outer surface of the back teeth 1006 is located on the right side of the mouth).

[0209] For example, Figure 10B FIG. 1 is a schematic diagram of an occlusal surface image captured by a camera module in one embodiment. Figure 10B As shown, the oral region may include an upper occlusal surface and a lower occlusal surface, and the camera module may capture an image of the lower occlusal surface of the oral region, as well as an image of the upper occlusal surface.

[0210] As an embodiment, the first parameter and / or the second parameter corresponding to different oral regions may be the same or different, for example, Figure 10AAs shown, when the oral imaging device is located directly in front of the user's oral cavity, the right posterior tooth outer surface 1004 and the left posterior tooth outer surface 1006 are symmetrical, and the right posterior tooth outer surface 1004 and the left posterior tooth outer surface 1006 can correspond to the same first parameter and second parameter. For another example, the front tooth outer surface 1002 and the right posterior tooth outer surface 1004 or the left posterior tooth outer surface 1006 can correspond to different first parameters and / or second parameters, respectively.

[0211] In some embodiments, the oral area corresponding to the photographed object may include any one of the occlusal surface, the inner surface, and the outer surface, wherein the first luminescence parameter corresponding to the occlusal surface is less than or equal to the first luminescence parameter corresponding to the inner surface, and / or the first luminescence parameter corresponding to the occlusal surface is greater than or equal to the first luminescence parameter corresponding to the outer surface, and / or the second luminescence parameter corresponding to the occlusal surface is less than or equal to the second luminescence parameter corresponding to the inner surface, and / or the second luminescence parameter corresponding to the occlusal surface is greater than or equal to the second luminescence parameter corresponding to the outer surface.

[0212] For example, when using an oral camera to photograph the outer surface, the ambient light is large or the oral camera is not affected by the ambient light. Therefore, the luminous parameters corresponding to the occlusal surface may be greater than or equal to the target luminous parameters corresponding to the outer surface, so that the intensity of light emitted by the light-emitting module when the oral camera is photographing the occlusal surface is greater than or equal to the intensity of light emitted by the light-emitting module when the oral camera is photographing the outer surface.

[0213] In the above-mentioned embodiment, the oral photographing equipment can adjust the light-emitting parameters of the light-emitting module in the first photographing mode and / or the second photographing mode according to whether the inner surface, occlusal surface or outer surface of the tooth is photographed, so that the intensity of the light emitted by the light-emitting module matches the tooth surface corresponding to the photographed object, thereby reducing the adverse effects of ambient light on the photographed image and improving the image quality of the photographed image.

[0214] Furthermore, the tooth surface includes the outer side of the front teeth and the outer side of the back teeth. In some embodiments, the oral photography device can be as follows Figure 2A In the product form shown, when using the oral photography device 200 to photograph the outer surface, the opener 240 is connected to the main body 210. The user can bite the opener 240 or place one end of the opener 240 against the teeth. The opener 240 can open the lips and maintain the user's oral position.

[0215] When the mouth opener 240 is connected to the main body 210, the oral photography device 200 is not affected by ambient light. However, due to the influence of tooth morphology, since the curvature of the anterior teeth is larger and the curvature of the posterior teeth is smaller (flatter), when the oral photography device 200 is used to photograph the outer surface of the anterior teeth, the distance between the outer surface of the anterior teeth and the photographing unit 230 (i.e., the camera module) is smaller than the distance between the outer surface of the posterior teeth and the photographing unit 230 (i.e., the camera module) when the oral photography device 200 is used to photograph the outer surface of the posterior teeth. Therefore, the first parameter corresponding to the outer surface of the anterior teeth may be less than or equal to the first parameter corresponding to the outer surface of the posterior teeth, and / or the second parameter corresponding to the outer surface of the anterior teeth may be less than or equal to the second parameter corresponding to the outer surface of the posterior teeth.

[0216] Optionally, due to the distance between the outer side of the front teeth and the shooting unit 230 (that is, the camera module), and the distance between the outer side of the posterior teeth and the shooting unit 230 (that is, the camera module) is smaller, therefore, the first luminous parameters corresponding to the outer side of the front teeth and the outer side of the posterior teeth respectively may be the same, the second luminous parameters corresponding to the outer side of the front teeth and the outer side of the posterior teeth respectively may be the same, and the first shooting parameters and / or the second shooting parameters corresponding to the outer side of the front teeth and the outer side of the posterior teeth respectively may be different, that is, only the shooting parameters of the camera module are adjusted without adjusting the luminous parameters of the light-emitting module, thereby improving the accuracy of parameter adjustment. It should be noted that the luminous parameters of the light-emitting module and the shooting parameters of the camera module can also be adjusted simultaneously, which is not limited here.

[0217] In the above-mentioned embodiment, when using an oral camera to shoot the outer surface, the mouth opener is connected to the main body, and the corresponding first parameter and / or second parameter can be adjusted according to whether the shooting object is the outer surface of the front teeth or the outer surface of the back teeth. This can avoid the different distances between the outer surface of the front teeth and the outer surface of the back teeth and the camera module due to the tooth shape, which affects the quality of the image shot by the oral camera, thereby improving the equipment performance of the oral camera.

[0218] In some embodiments, the shooting information may include the shooting position of the camera module in the user's oral cavity, and the oral camera device may determine the first parameter and / or the second parameter based on the shooting position of the camera module in the user's oral cavity. The shooting position of the camera module in the user's oral cavity includes the tooth area and / or tooth surface, and there are at least two shooting positions corresponding to different first parameters and / or second parameters.

[0219] Optionally, the shooting position of the camera module in the user's mouth can be represented by the oral area where the subject photographed by the camera module is located. Therefore, the shooting position corresponds to different first parameters and / or second parameters, which may be similar to the first parameters and / or second parameters of the oral area corresponding to the subject introduced in the above embodiments, and will not be repeated here.

[0220] Optionally, the shooting position of the camera module in the user's mouth can be represented by the oral area in the user's mouth closest to the camera module. If the oral area in the user's mouth closest to the camera module is different, it may correspond to the same or different first parameters and / or second parameters.

[0221] Optionally, the shooting position of the camera module in the user's mouth may be the precise position of the camera module relative to the mouth. The shooting position of the camera module in the user's mouth may include the relative distance and relative direction (i.e., relative angle) between the camera module and the shooting object. When the relative distance and relative direction between the camera module and the shooting object are different, they may correspond to the same or different first parameters and / or second parameters.

[0222] In the above-mentioned embodiment, the oral camera device can determine the first parameter and / or the second parameter according to the oral area where the photographed object is located and / or the shooting position of the camera module in the user's mouth, so that the determined first parameter and / or second parameter are adapted to the oral area where the photographed object is located and / or the shooting position of the camera module in the user's mouth, thereby improving the accuracy of the adjustment of the first parameter and / or the second parameter, thereby improving the image quality of the image obtained by the oral camera device shooting different oral areas and / or shooting at different shooting positions.

[0223] As an embodiment, the shooting information may include the distance between the camera module and the shooting object, and the oral shooting device may determine the first parameter and the second parameter according to the distance between the camera module and the shooting object. Furthermore, the first parameter and / or the second parameter are positively correlated with the distance between the camera module and the shooting object. In the case where the distance between the camera module and the shooting object is large, the attenuation of the light emitted by the light-emitting module during the propagation process is large, and therefore, a larger first parameter and / or second parameter may be used to avoid the situation where the captured image is too dark due to the long distance between the camera module and the shooting object. In the case where the distance between the camera module and the shooting object is small, the attenuation of the light emitted by the light-emitting module during the propagation process is small, and therefore, a smaller first parameter and / or second parameter may be used to avoid the situation where the captured image is overexposed due to the short distance between the camera module and the shooting object.

[0224] As an embodiment, the shooting information may include the area of ​​the oral region corresponding to the shooting object, and the oral shooting device may determine the first parameter and the second parameter according to the area of ​​the oral region corresponding to the shooting object. Furthermore, the first parameter and / or the second parameter are positively correlated with the area of ​​the oral region corresponding to the shooting object. In the case where the area of ​​the oral region corresponding to the shooting object is small, it means that the distance between the camera module and the shooting object is large, and the attenuation of the light emitted by the light-emitting module during the propagation process is large. Therefore, a larger first parameter and / or second parameter may be used to avoid the situation where the captured image is too dark due to the long distance between the camera module and the shooting object. In the case where the area of ​​the oral region corresponding to the shooting object is large, it means that the distance between the camera module and the shooting object is small, and the attenuation of the light emitted by the light-emitting module during the propagation process is small. Therefore, a smaller first parameter and / or second parameter may be used to avoid the situation where the captured image is overexposed due to the short distance between the camera module and the shooting object.

[0225] In the above-mentioned embodiment, the oral photographing equipment can adjust the first parameter and / or the second parameter according to the corresponding relationship between the first parameter and / or the second parameter and the shooting information, and according to the shooting information obtained in real time. As the distance between the camera module and the shooting object increases, the first parameter and / or the second parameter is increased. This can avoid problems such as overexposure or too dark images of the shooting object captured by the camera module due to different distances between the camera module and the shooting object, thereby improving the image quality of the oral images captured by the oral photographing equipment.

[0226] In some embodiments, the photographic information may include an entry state corresponding to the camera module, where the entry state may include an extraoral state or an intraoral state. The oral photographic device may determine the first parameter and / or the second parameter based on the entry state corresponding to the camera module. The extraoral state and the intraoral state may correspond to different first parameters and / or second parameters, respectively.

[0227] Optionally, when the camera module is in the intraoral state or the extraoral state, the oral camera device can correspond to different product forms respectively. For example, Figure 2A and 2B As shown, when the camera module is in the extraoral state, the mouth-opener 240 is connected to the main body 210, and when the camera module is in the intraoral state, the mouth-opener 240 is detached from the main body 210. Since the oral camera device corresponds to different product forms when the camera module is in the intraoral state or the extraoral state, the captured image is affected differently. Therefore, the camera module in the intraoral state or the extraoral state can correspond to different first parameters and / or second parameters.

[0228] Optionally, when the camera module is in the intraoral state or the extraoral state, the distance between the camera module and the photographed object may be different. Therefore, the camera module in the intraoral state or the extraoral state may correspond to different first parameters and / or second parameters, respectively.

[0229] Optionally, when the camera module is in the intraoral state or the extraoral state, the camera module is affected differently by the ambient light. Therefore, the camera module in the intraoral state or the extraoral state may correspond to different first parameters and / or second parameters, respectively.

[0230] Furthermore, the first luminous parameter corresponding to the intraoral state is greater than or equal to the first luminous parameter corresponding to the extraoral state, and / or the second luminous parameter corresponding to the intraoral state is greater than or equal to the second luminous parameter corresponding to the extraoral state. When the camera module is in the intraoral state, the ambient light of the camera module is relatively small due to the relatively small oral space, while when the camera module is in the extraoral state, the ambient light is relatively large or the oral camera device is not affected by the ambient light. Therefore, the first luminous parameter and / or the second luminous parameter corresponding to the intraoral state may be greater than or equal to the first luminous parameter and / or the second luminous parameter corresponding to the extraoral state, so that when the camera module is in the intraoral state, the intensity of the light emitted by the luminous module is greater than or equal to the intensity of the light emitted by the luminous module when the camera module is in the extraoral state.

[0231] In the above-mentioned embodiment, the oral shooting equipment can adjust the light-emitting parameters of the light-emitting module in the first shooting mode and / or the second shooting mode according to whether the camera module is in the intraoral state or the extraoral state, so that the intensity of the light emitted by the light-emitting module matches the entrance state of the camera module, thereby reducing the adverse effects of ambient light on the captured image and improving the image quality of the captured image.

[0232] In some embodiments, the above-mentioned shooting information can be determined based on images obtained by an oral shooting device.

[0233] The oral imaging device can capture images through a camera module and identify the images captured by the camera module to obtain imaging information. For example, if the imaging information includes an oral region corresponding to the photographed subject, the oral imaging device can identify the oral region contained in the image and determine the oral region corresponding to the photographed subject.

[0234] For example, taking the case where the shooting information includes the area of ​​the oral region corresponding to the shooting object, the oral shooting equipment can detect the edge corresponding to the oral region contained in the image, and determine the image area corresponding to the oral region based on the edge corresponding to the oral region, and determine the area of ​​the oral region corresponding to the shooting object based on the area of ​​the image area corresponding to the oral region.

[0235] For example, taking the case where the shooting information includes the entrance state corresponding to the camera module, the oral shooting device can recognize the image content of the image, and determine whether the camera module is in the intraoral state or the extraoral state based on the recognized image content, and obtain the entrance state corresponding to the camera module.

[0236] In some embodiments, the shooting information determined according to the acquired image includes a tooth surface corresponding to the shooting object, and the tooth surface includes at least one of an occlusal surface, a medial surface, and a lateral surface.

[0237] In some embodiments, the oral imaging device may be Figure 2A The product structure shown in FIG. 1 may include information about the opening device, including information about the opening device 240 connected to the main body 210 or detached from the main body 210, according to the shooting information determined based on the acquired image. When the opening device 240 is connected to the main body 210, the image captured by the camera module may include edge features (such as a circle or a circle) that match the opening shape of the opening device 240. If an edge feature that matches the opening shape of the mouth opener 240 is identified in the acquired image, the mouth opener information can be determined to be that the mouth opener 240 is connected to the main body 210. Further, it can be determined that the camera module is in the extraoral state. When the mouth opener 240 is disassembled from the main body 210, the image captured by the camera module does not contain an edge feature that matches the opening shape of the mouth opener 240. Therefore, if an edge feature that matches the opening shape of the mouth opener 240 is not identified in the acquired image, the mouth opener information can be determined to be that the mouth opener 240 is disassembled from the main body 210.

[0238] As an optional embodiment, the oral imaging device may store one or more neural networks, and use these one or more neural networks to recognize images captured by the oral imaging device to obtain imaging information. One neural network may correspond to one type of imaging information, or a neural network may correspond to multiple types of imaging information.

[0239] In an embodiment of the present application, the oral photographing device can determine the shooting information based on the acquired image, thereby improving the accuracy of the determined shooting information, thereby improving the accuracy of the target parameter adjustment, and does not rely on external sensors, reducing the number of sensors set in the oral photographing device, making the structure of the oral photographing device simpler, and reducing costs.

[0240] In some embodiments, the oral photography device may include a sensor, and the above-mentioned photography information may be determined by information acquired by the sensor.

[0241] Optionally, the sensor may include but is not limited to at least one of a distance sensor, a position sensor, and an entrance sensor.

[0242] The distance sensor can be used to detect the distance between the camera module and the subject. For example, the distance sensor may include, but is not limited to, an optical distance sensor (such as a laser distance sensor, an infrared distance sensor, etc.), an ultrasonic distance sensor, etc. For example, taking an optical distance sensor as an example, the distance sensor can emit a light pulse and measure the time from the light pulse being emitted to the light pulse being reflected back from the subject, and calculate the distance between the camera module and the subject based on this time.

[0243] The position sensor can be used to detect the shooting position of the camera module in the user's mouth. For example, the position sensor may include, but is not limited to, one or more of a gyroscope, an accelerometer, and an IMU (Inertial Measurement Unit). The oral camera device can determine the shooting position of the camera module in the user's mouth based on the information collected by the position sensor. Alternatively, the oral camera device can determine the shooting position of the camera module in the user's mouth based on the information collected by the position sensor and the image collected by the camera module.

[0244] In the embodiment of the present application, the oral photography device can determine the photography information based on the information collected by the sensor, thereby improving the accuracy and flexibility of the determined photography information.

[0245] As an optional embodiment, the aforementioned photographic information may be determined jointly by images captured by the intraoral camera and information collected by the sensor. For example, some photographic information may be determined by images captured by the intraoral camera, while others may be determined by information collected by the sensor. Alternatively, a particular photographic type may be determined jointly by images captured by the intraoral camera and information collected by the sensor, without limitation.

[0246] In some embodiments, the oral photography device can determine the first photography parameters corresponding to the camera module in the first photography mode, and determine the second lighting parameters corresponding to the lighting module and the second photography parameters corresponding to the camera module in the second photography mode based on the photography information.

[0247] When the intraoral camera is in a first shooting mode, first shooting parameters are determined based on the shooting information. In this first shooting mode, the first lighting parameters corresponding to the light-emitting module may be preset lighting parameters. When the intraoral camera is in the first shooting mode, the light-emitting module may only emit light in the first wavelength band. The light emitted by the light-emitting module serves as illumination. Compared to adjusting the lighting parameters of the light-emitting module, adjusting the shooting parameters of the camera module can significantly improve image quality. Therefore, when the intraoral camera is in the first shooting mode, the lighting parameters corresponding to the light-emitting module may be preset lighting parameters. That is, the lighting parameters corresponding to the light-emitting module remain unchanged. The intraoral camera only adjusts the shooting parameters of the camera module based on the shooting information, thereby improving the efficiency of parameter adjustment.

[0248] For example, the light-emitting module of the intraoral camera may include two white lights (for emitting light in a first wavelength band) and four purple lights (for emitting light in a second wavelength band). When the intraoral camera is in the first shooting mode, the four purple lights may be off, and the two white lights may be on. The lighting parameters of the light-emitting module and the shooting parameters of the camera module may be as shown in Table 1.

[0249] Table 1

[0250] oral area Purple light brightness White light 1 brightness White light 2 brightness Auto Exposure Expected Mean Upper occlusal surface 0％ 100％ 10％ 1000 Lower occlusal surface 0％ 100％ 10％ 788 Outer surface of anterior teeth 0％ 100％ 10％ 960 Outer surface of posterior teeth 0％ 100％ 10％ 1500 inner side 0％ 100％ 10％ 2500

[0251] When the intraoral camera is in the second shooting mode, the light module emits at least a second wavelength of light to enhance the presentation of undesirable substances or diseased areas in the oral cavity in the image. Light in the second wavelength is susceptible to the distance between the camera module and the subject being photographed. Therefore, when the intraoral camera is in the second shooting mode, the intraoral camera can jointly adjust the light emission parameters of the light module and the shooting parameters of the camera module based on the shooting information. Therefore, the second light emission parameters of the light module and the second shooting parameters of the camera module corresponding to the second shooting mode can be determined based on the shooting information.

[0252] In some embodiments, in the second shooting mode, the light emitting module emits light of the first band and light of the second band. Since the light of the first band and the light of the second band are affected differently by the ambient light, when the shooting information sent changes, the parameter adjustment value corresponding to the light of the first band is different from the parameter adjustment value corresponding to the light of the second band.

[0253] The parameter adjustment value may refer to the difference between the luminous parameters corresponding to the shooting information before the change and the luminous parameters corresponding to the shooting information after the change. The parameter adjustment value corresponding to the light of the first wavelength band may refer to the parameter adjustment value of the first type of lamp, and the parameter adjustment value corresponding to the light of the second wavelength band may refer to the parameter adjustment value of the second type of lamp.

[0254] Furthermore, since there is usually more white light in the ambient light, the ambient light has a greater impact on the light of the first band and a smaller impact on the light of the second band. Therefore, when the shooting information changes, in the second shooting mode, the parameter adjustment value corresponding to the light of the first band is greater than the parameter adjustment value corresponding to the light of the second band.

[0255] Exemplarily, the parameter adjustment values ​​corresponding to the first wavelength band of light and the occlusal surface and the outer surface of the oral cavity are greater than the parameter adjustment values ​​corresponding to the second wavelength band of light and the occlusal surface and the outer surface of the oral cavity.

[0256] In the second shooting mode, corresponding light-emitting parameters are adjusted for light of different wavelength bands, thereby improving the accuracy of adjusting the light-emitting parameters of the light-emitting module and further improving the image quality of the image captured by the camera module.

[0257] For example, the light-emitting module of the intraoral camera may include two white lights (for emitting light in the first wavelength band) and four purple lights (for emitting light in the second wavelength band). When the intraoral camera is in the second shooting mode, the four purple lights may be illuminated, one white light may be illuminated, and the other white light may be unlit. The lighting parameters of the light-emitting module and the shooting parameters of the camera module may be as shown in Table 2.

[0258] Table 2

[0259] oral area Purple light brightness White light 1 brightness White light 2 brightness Auto Exposure Expected Mean Upper occlusal surface 100％ 50％ 0％ 1000 Lower occlusal surface 100％ 50％ 0％ 960 Outer surface of anterior teeth 70％ 10％ 0％ 1500 Outer surface of posterior teeth 80％ 10％ 0％ 1500 inner side 100％ 50％ 0％ 1500

[0260] In an embodiment of the present application, when the oral photographing device is in the second shooting mode, the oral photographing device can jointly adjust the second light-emitting parameters of the light-emitting module and the second shooting parameters of the camera module according to the shooting information, thereby improving the image quality of the image taken in the second shooting mode and helping to conduct a more accurate analysis of the oral condition later.
