Description

Technical Field

[0001] The present application relates to the technical field of oral detection devices, and particularly to a photographing device and an oral detection device. Background Art

[0002] With the increasing attention of people to oral health, various oral detection devices have emerged accordingly. Oral detection devices usually capture the state inside the oral cavity through a camera and display it in real time on a monitor for the convenience of doctors' clinical examinations and people's daily oral health monitoring.

[0003] However, in the related art, when using an oral detection device to detect teeth, the photographing device in the oral detection device usually cannot capture different positions of the oral cavity simultaneously. In this way, if different positions of the oral cavity need to be captured, it is necessary to adjust the photographing angle for multiple shootings, which takes a long time. Summary of the Utility Model

[0004] In view of the above deficiencies in the related art, the present application provides a photographing device and an oral detection device to solve the problem in the related art that different positions of the oral cavity cannot be captured simultaneously.

[0005] To solve the above technical problems, in a first aspect, the present application provides a photographing device, which includes:

[0006] A main body component, the main body component includes a mounting bracket;

[0007] At least two cameras, at least two cameras are arranged on the mounting bracket, and the image acquisition directions of the first camera and the second camera among at least two cameras are arranged at an angle, so that the first camera and the second camera respectively capture different positions of the oral cavity; and,

[0008] A power supply component, the power supply component is arranged on the main body component, and the power supply component is electrically connected to the camera to supply power to the camera.

[0009] In the present application, since the image acquisition directions of the first camera and the second camera are arranged at an angle, the first camera and the second camera have different image acquisition directions. In this way, when using the photographing device in the present application to capture the oral cavity, the first camera and the second camera can capture the oral cavity from different directions respectively. That is, the first camera and the second camera can capture different positions of the oral cavity, and then the photographing device can capture different positions of the oral cavity simultaneously. Compared with the related art, it is no longer necessary to adjust the photographing angle for multiple shootings, which is beneficial to reducing the time consumption and improving the working efficiency of photographing.

[0010] In a possible implementation of the first aspect, the main body component further includes a handle. The mounting bracket is connected to the handle, and the power supply component is disposed in the handle. The length extension direction of the handle is the first direction, and the direction perpendicular to the first direction is the second direction.

[0011] The first camera and the second camera are spaced along the first direction, and / or the first camera and the second camera are spaced along the second direction.

[0012] First, when the first camera and the second camera are spaced along the first direction, since the first direction is the length extension direction of the handle, in this way, on the one hand, the arrangement along the first direction makes the spatial layout of the two cameras have certain regularity and directionality. In the assembly process, the staff can install the cameras in sequence according to the preset first direction. The clear installation order and direction reduce the complexity of the assembly and facilitate the assembly. On the other hand, the arrangement of the cameras along the first direction provides a clear path planning for wiring. In this way, the wires can be arranged along the length direction of the handle, avoiding the chaos and crossing of the lines and facilitating the wiring. On the third hand, since it is convenient to move the photographing device along the length direction of the handle, the cameras arranged at intervals along the first direction are also convenient for aligning with the teeth.

[0013] Secondly, when the first camera and the second camera are spaced along the second direction, since the second direction is perpendicular to the length direction of the handle, and in use the second direction is perpendicular to the arrangement direction of the teeth to a certain extent. Therefore, when photographing the teeth deep in the oral cavity, on the premise of ensuring that the second direction is perpendicular to the arrangement direction of the teeth, the length direction of the handle is the same as the oral cavity depth direction to a certain extent. In this way, the interference between the handle and the oral cavity can be reduced, and it is convenient to align the camera with the teeth deep in the oral cavity to clearly photograph the teeth deep in the oral cavity. At the same time, it can also make the camera conveniently align with the teeth at the lip.

[0014] Finally, when the first camera and the second camera are spaced along the first direction and the second direction, since the cameras are spaced in two different directions at the same time, it is beneficial to comprehensively cover the object to be photographed and more likely to include the object to be photographed in the photographing field of view.

[0015] In a possible implementation of the first aspect, the direction perpendicular to the first direction and the second direction is the third direction, and the first camera and the second camera are also spaced along the third direction.

[0016] The interval setting in combination with the first direction and / or the second direction, plus the interval in the third direction, enables the camera to cover the object to be photographed more comprehensively in three-dimensional space, and can photograph the same object to be photographed from more angles and directions, which helps to obtain richer image details and better understand the lesion condition of the object to be photographed.

[0017] In a possible implementation of the first aspect, the angular range of the angle between the image acquisition directions of the first camera and the second camera is 60° - 150°.

[0018] With such a setting, while ensuring that the first camera and the second camera can clearly photograph the object to be photographed, it can not only avoid the problem of easy emergence of blind areas due to too large an angle, but also avoid the problem of being unfavorable for aligning the object to be photographed due to too small an angle.

[0019] In a possible implementation of the first aspect, the field of view angles of the first camera and the second camera are used to jointly cover the inner side, outer side and occlusal surface of the same tooth. The inner side is the side of the tooth close to the tongue, and the outer side is the side of the tooth away from the tongue.

[0020] With such a setting, it can not only fully ensure that the photographing device can simultaneously photograph the inner side, outer side and occlusal surface of the same tooth, but also enable the doctor to more comprehensively understand the conditions of various parts of the tooth, so as to more accurately discover problems and avoid missed diagnoses.

[0021] In a possible implementation of the first aspect, the camera is a fixed-focus camera.

[0022] With such a setting, on the one hand, since the fixed-focus camera has high optical performance and can provide clear and sharp images, it can ensure the clarity and detail performance of the images and provide reliable image information for the doctor. On the other hand, since the fixed-focus camera can provide more accurate color reproduction, and accurate color reproduction can help the doctor better judge the health condition of the object to be photographed and improve the accuracy of diagnosis.

[0023] In a possible implementation of the first aspect, the photographing device further includes:

[0024] A position limiting structure, the position limiting structure is arranged on the mounting bracket, and the position limiting structure is used to contact the surface of the tooth to limit the distance between the camera and the surface of the tooth.

[0025] With such a setting, on the one hand, the position limiting structure can control the distance between the camera and the tooth surface, ensuring that the camera is always within the optimal shooting distance range, thus obtaining clear and stable images. On the other hand, the position limiting structure can help the doctor quickly and accurately position the camera to the appropriate position without repeatedly adjusting the position of the camera, which is beneficial to improving work efficiency.

[0026] In a possible implementation of the first aspect, the position limiting structure includes a positioning surface for contacting the occlusal surface of the tooth to define the distance between the camera and the surface of the tooth.

[0027] Since the sizes and shapes of teeth vary among different people, but the occlusal surface usually has relatively regular curved surface features, and the positioning surface can better fit the occlusal surfaces of different people's teeth, ensuring that the distance between the camera and the tooth surface remains consistent during each shooting, and also enhancing the stability of the camera.

[0028] In a possible implementation of the first aspect, the position limiting structure is detachably connected to the mounting bracket.

[0029] Since there are various bacteria and dirt in the oral cavity environment, and the position limiting structure is in direct contact with the teeth and is easily contaminated, the position limiting structure is detachably connected to the mounting bracket. In this way, when shooting different patients, a clean position limiting structure can be replaced to avoid cross-contamination.

[0030] In a possible implementation of the first aspect, a card slot is provided on one of the position limiting structure and the mounting bracket, and a buckle is provided on the other, and the buckle is engaged with the card slot to detachably connect the position limiting structure to the mounting bracket.

[0031] With such a setting, on the one hand, after the snap connection is in place, the buckle will tightly engage in the card slot, which can prevent the position limiting structure from accidentally falling off during use and enable the position limiting structure and the mounting bracket to be firmly connected.

[0032] On the other hand, the snap connection method between the buckle and the card slot is simple and fast. When installing the position limiting structure, only need to align the buckle with the card slot and gently push it to achieve a firm connection between the two. Similarly, when disassembling, by simply pressing or pulling the position limiting structure or the mounting bracket, the position limiting structure can be easily separated from the mounting bracket. This fast installation and disassembly method greatly improves work efficiency, especially when the position limiting structure needs to be frequently replaced or equipment maintenance is required.

[0033] In a possible implementation of the first aspect, the mounting bracket includes two mounting parts, and the first camera and the second camera are respectively arranged on the two mounting parts.

[0034] The first camera and the second camera are respectively arranged on two mounting parts, which can reduce the mutual interference between the two cameras, maintain a stable shooting state, and thus is conducive to improving the quality of the images.

[0035] In a possible implementation manner of the first aspect, the photographing device further includes a rotating member, the rotating member is arranged on the main body member, and the rotating member is used to drive the two mounting parts to rotate in different directions, so as to drive the first camera and the second camera to rotate in different directions.

[0036] By rotating the first camera and the second camera in different directions through the rotating member, the shooting range can be expanded. In this way, it is no longer limited to a fixed image acquisition direction, and the image acquisition direction of the camera can be flexibly adjusted according to actual needs to capture more pictures at different positions, which is conducive to enhancing the adaptability of the photographing device for use in the oral cavity.

[0037] In a possible implementation manner of the first aspect, the position limiting structure is a positioning shell, and two accommodating grooves are arranged on the positioning shell. The two accommodating grooves are respectively used for accommodating the two mounting parts, and the shapes of the two accommodating grooves are respectively adapted to the shapes of the two mounting parts.

[0038] With such an arrangement, on the one hand, the tight fit between the accommodating groove and the mounting part can enhance the stability of the positioning shell when mounted on the mounting bracket. In this way, during the shooting process, the shaking of the positioning shell can be effectively prevented, so as to ensure that the camera is always within the optimal shooting distance range, thereby obtaining clear and stable images. On the other hand, it can provide a certain degree of protection for the two mounting parts, so that during use and storage, the risk of damage to the mounting parts and the camera can be reduced, and the service life of the photographing device can be extended.

[0039] In a possible implementation manner of the first aspect, the photographing device further includes a first light source and a second light source. The irradiation direction of the first light source is the same as the image acquisition direction of the first camera, and the irradiation direction of the second light source is the same as the image acquisition direction of the second camera;

[0040] The power supply component is also electrically connected to the first light source and the second light source to supply power to the first light source and the second light source.

[0041] The light source is consistent with the image acquisition direction of the camera, which can provide direct illumination for the shooting area, so that the brightness of the shooting area can be significantly enhanced, and the details of the shooting object can be more clearly visible.

[0042] In a possible implementation of the first aspect, the first light source is in a ring shape and is sleeved outside the lens of the first camera; and / or, the second light source is in a ring shape and is sleeved outside the lens of the second camera.

[0043] The ring-shaped light source can provide omnidirectional illumination around the lens of the camera. In this way, no matter from which angle the camera takes a picture, it can ensure that the object being photographed receives uniform light, and there will be no local shadows or uneven illumination.

[0044] In a possible implementation of the first aspect, the first light source and / or the second light source are used to irradiate the surface of the teeth with light of a specific wavelength, so that different substances on the tooth surface reflect different fluorescence reactions.

[0045] With such a setting, on the one hand, the light of a specific wavelength can stimulate the fluorescence reaction of different substances on the tooth surface. For dental lesions such as dental caries, cracks, and dental plaque, the substances in these lesion sites have different fluorescence reactions from normal tooth tissues at a specific wavelength. By observing the differences in fluorescence reactions, doctors can more easily detect these potential problems and thus carry out timely intervention and treatment.

[0046] On the other hand, the intensity and color of the fluorescence reaction can reflect the degree of the lesion. By analyzing the changes in the fluorescence reaction, doctors can evaluate the severity of the lesion and provide a more specific basis for treatment.

[0047] In a possible implementation of the first aspect, the photographing device further includes a filter, and the filter is used to filter out light other than the fluorescence reaction;

[0048] The filter is provided on the lens of the first camera, and / or the filter is provided on the lens of the second camera.

[0049] The filter can effectively filter out light of non-specific wavelengths and only allow specific wavelength light related to the fluorescence reaction to pass through. This can reduce the influence of other light, enhance the intensity of the fluorescence signal, make the fluorescence reaction on the tooth surface more obvious, and thus doctors can clearly observe the fluorescence changes and improve the detection and diagnosis accuracy of lesions.

[0050] In a second aspect, the present application further provides an oral detection device, and the oral detection device includes:

[0051] The photographing device according to any one of the first aspect.

[0052] In this application, since the image acquisition directions of the first camera and the second camera in the photographing device are set at an angle, the first camera and the second camera have different image acquisition directions. When using the photographing device in this application to photograph the oral cavity, the first camera and the second camera can respectively photograph the oral cavity from different directions. That is, the first camera and the second camera can photograph different positions of the oral cavity, and then the photographing device can simultaneously photograph different positions of the oral cavity. Compared with the related art, there is no need to adjust the photographing angle for multiple shootings, which is beneficial to reducing the time consumption and improving the work efficiency of photographing.

[0074] As described in the background art of the present application, with the increasing attention of people to oral health, various oral detection devices have emerged accordingly. Oral detection devices usually capture the status inside the oral cavity through a camera and display it in real time on a display for the convenience of doctors' clinical examinations and people's daily oral health monitoring.

[0075] However, in the related art, when using an oral cavity detection device to detect teeth, the imaging device in the oral cavity detection device usually cannot simultaneously capture different positions of the oral cavity. In this case, if different positions of the oral cavity need to be captured, the imaging angle needs to be adjusted for multiple captures, which takes a long time.

[0076] Embodiment 1

[0077] In view of the above problems, the present application provides an imaging device to solve the problem in the related art that different positions of the oral cavity cannot be simultaneously captured.

[0078] The technical solution of the present application will be further described below in conjunction with specific embodiments and the accompanying drawings:

[0079] As Figure 1 , Figure 2 and Figure 3 shown, the imaging device 100 includes a main body component, at least two cameras, and a power supply component. Among them, the main body component includes a mounting bracket 1, at least two cameras are arranged on the mounting bracket 1, and the image acquisition directions of the first camera 2 and the second camera 3 among the at least two cameras are arranged at an angle, so that the first camera 2 and the second camera 3 respectively capture different positions of the oral cavity. The power supply component is arranged on the main body component and is electrically connected to the cameras to supply power to the cameras.

[0080] In the present application, since the image acquisition directions of the first camera 2 and the second camera 3 are arranged at an angle, the first camera 2 and the second camera 3 have different image acquisition directions. When using the imaging device 100 in the present application to capture the oral cavity, the first camera 2 and the second camera 3 can respectively capture different positions of the oral cavity from different directions. That is, the first camera 2 and the second camera 3 can capture different positions of the oral cavity, and then the imaging device 100 can simultaneously capture different positions of the oral cavity. Compared with the related art, there is no need to adjust the imaging angle for multiple captures, which is conducive to reducing the time consumption and improving the work efficiency of imaging.

[0081] Regarding the number of cameras set, in this embodiment, taking the case of setting two cameras as an example for illustration, that is, the two cameras are the first camera 2 and the second camera 3 respectively. In other embodiments, according to actual usage requirements, the number of cameras can also be set to three, four, etc. The number of cameras is set relatively flexibly, and the embodiments of the present application do not make specific limitations on this.

[0082] As Figure 1 and Figure 3 shown, the main body component further includes a handle 4, the mounting bracket 1 is connected to the handle 4, the power supply component is arranged on the handle 4, and the length extension direction of the handle 4 is the first direction (as Figure 3in the Y direction), the direction perpendicular to the first direction is the second direction (such as Figure 3 the X direction in

[0083] For the arrangement of the first camera 2 and the second camera 3, in the first implementation manner, as Figure 3 shown, the first camera 2 and the second camera 3 are arranged at intervals along the second direction.

[0084] Since the second direction is perpendicular to the length direction of the handle 4, and during use, the second direction is perpendicular to the tooth arrangement direction to a certain extent. Therefore, when photographing the teeth deep in the oral cavity, while ensuring that the second direction is perpendicular to the tooth arrangement direction, the length direction of the handle 4 is the same as the oral cavity depth direction to a certain extent, so as to reduce the interference between the handle 4 and the oral cavity and facilitate aligning the camera with the teeth deep in the oral cavity for clearly photographing the teeth deep in the oral cavity.

[0085] In the second implementation manner, the first camera 2 and the second camera 3 are arranged at intervals along the first direction (not shown).

[0086] Since the first direction is the length extension direction of the handle 4, thus arranged, on the one hand, arranging at intervals along the first direction makes the spatial layout of the two cameras have certain regularity and directionality. In this way, during the assembly process, the staff can install the cameras in sequence according to the preset first direction, and the clear installation order and direction reduce the complexity of the assembly and facilitate the assembly. On the other hand, arranging the cameras at intervals along the first direction provides a clear path planning for wiring, so that the wires can be arranged along the length direction of the handle 4, avoiding the chaos and crossing of the lines and facilitating the wiring. On the third hand, since it is convenient to move the photographing device 100 along the length direction of the handle 4, the cameras arranged at intervals along the first direction are also convenient for aligning with the teeth.

[0087] In the second implementation manner, the first camera 2 and the second camera 3 are arranged at intervals along the second direction, and the first camera 2 and the second camera 3 are also arranged at intervals along the first direction (not shown).

[0088] Since the cameras are arranged at intervals in two different directions simultaneously, it is beneficial to comprehensively cover the object to be photographed and has a greater probability of including the object to be photographed in the photographing field of view.

[0089] Based on any of the above arrangements of the first camera 2 and the second camera 3, further, the direction perpendicular to the first direction (such as Figure 3 the Y direction in Figure 3 and the second direction (such as

[0090] Combined with the interval settings in the first direction and / or the second direction, plus the interval in the third direction, the camera can cover the object to be photographed more comprehensively in three-dimensional space, and can photograph the same object to be photographed from more angles and directions, which helps to obtain richer image details and better understand the lesion condition of the object to be photographed.

[0091] Regarding the included angle of the field of view, further, the included angle range between the image acquisition directions of the first camera 2 and the second camera 3 is 60° - 150°.

[0092] With such a setting, while ensuring that the first camera 2 and the second camera 3 can clearly photograph the object to be photographed, it can not only avoid the problem of easy emergence of blind areas due to too large an included angle, but also avoid the problem of being unfavorable for aligning the object to be photographed due to too small an included angle.

[0093] In the embodiment of the present application, the included angle between the image acquisition directions of the first camera 2 and the second camera 3 can be 60°, 150° or any value within the range of 60° - 150°. Specifically, it can be determined according to the actual shooting requirements, and the embodiment of the present application does not make specific limitations on this.

[0094] Regarding the first camera 2 and the second camera 3, further, the field of view angles of the first camera 2 and the second camera 3 are used to jointly cover the inner side, outer side and occlusal surface of the same tooth, where the inner side is the side of the tooth close to the tongue, and the outer side is the side of the tooth away from the tongue.

[0095] With such a setting, it can not only fully ensure that the photographing device 100 can simultaneously photograph the inner side, outer side and occlusal surface of the same tooth, but also enable the doctor to more comprehensively understand the conditions of each part of the tooth, so as to more accurately discover problems and avoid missed diagnoses.

[0096] Regarding the camera, further, the camera is a fixed-focus camera.

[0097] With such a setting, on the one hand, because the fixed-focus camera has high optical performance and can provide clear and sharp images, it can ensure the clarity and detail performance of the images and provide reliable image information for the doctor. On the other hand, because the fixed-focus camera can provide more accurate color reproduction, and accurate color reproduction can help the doctor better judge the health condition of the object to be photographed and improve the accuracy of diagnosis.

[0098] Further, as Figure 1 shown, the photographing device 100 further includes a position limiting structure 5. The position limiting structure 5 is arranged on the mounting bracket 1, and the position limiting structure 5 is used to contact the surface of the tooth to limit the distance between the camera and the surface of the tooth.

[0099] With such a setting, on the one hand, the position-limiting structure 5 can control the distance between the camera and the tooth surface, ensuring that the camera is always within the optimal shooting distance range, thereby obtaining clear and stable images. On the other hand, the position-limiting structure 5 can help the doctor quickly and accurately position the camera to the appropriate position without repeatedly adjusting the position of the camera, which is beneficial to improving work efficiency.

[0100] Furthermore, as Figure 4 shown, the position-limiting structure 5 includes a positioning surface 51, and the positioning surface 51 is used to contact the occlusal surface of the tooth to limit the distance between the camera and the tooth surface.

[0101] Since there are differences in the size and shape of teeth among different people, but the occlusal surface usually has relatively regular curved surface characteristics, and the positioning surface 51 can better fit the occlusal surfaces of different people's teeth, ensuring that the distance between the camera and the tooth surface remains consistent during each shooting, and at the same time enhancing the stability of the camera.

[0102] For the position-limiting structure 5, furthermore, the position-limiting structure 5 is detachably connected to the mounting bracket 1.

[0103] Since there are various bacteria and dirt in the oral cavity environment, and the position-limiting structure 5 is in direct contact with the teeth and is easily contaminated, the position-limiting structure 5 is detachably connected to the mounting bracket 1. In this way, when shooting different patients, a clean position-limiting structure 5 can be replaced to avoid cross-contamination.

[0104] Furthermore, as Figure 3 and Figure 4 shown, a card slot 52 is provided on one of the position-limiting structure 5 and the mounting bracket 1, and a buckle 11 is provided on the other. The buckle 11 is engaged with the card slot 52 to detachably connect the position-limiting structure 5 to the mounting bracket 1.

[0105] With such a setting, on the one hand, after the snap connection is in place, the buckle 11 will tightly fit in the card slot 52, which can prevent the position-limiting structure 5 from accidentally falling off during use and enable the position-limiting structure 5 and the mounting bracket 1 to be firmly connected.

[0106] On the other hand, the snap connection method between the buckle 11 and the card slot 52 is simple and fast. When it is necessary to install the position-limiting structure 5, just align the buckle 11 with the card slot 52 and gently push it to achieve a firm connection between the two. Similarly, when disassembling, by simply pressing or pulling the position-limiting structure 5 or the mounting bracket 1, the position-limiting structure 5 can be easily separated from the mounting bracket 1. This fast installation and disassembly method greatly improves work efficiency, especially when it is necessary to frequently replace the position-limiting structure 5 or perform equipment maintenance.

[0107] In other embodiments, the position limiting structure 5 and the mounting bracket 1 can also be detachably connected by means of magnetic attraction or threaded connection. The detachable connection method between the position limiting structure 5 and the mounting bracket 1 is relatively flexible. Specifically, it can be selected according to specific usage requirements.

[0108] Regarding the structure of the mounting bracket 1, further, as Figure 3 shown, the mounting bracket 1 includes two mounting parts 12, and the first camera 2 and the second camera 3 are respectively arranged on the two mounting parts 12.

[0109] By respectively arranging the first camera 2 and the second camera 3 on the two mounting parts 12, the mutual interference between the two cameras can be reduced, a stable shooting state can be maintained, and thus the quality of the image is conducive to improvement.

[0110] Further, as Figure 3 shown, the two mounting parts 12 can be arranged in a V shape, or, as Figure 5 shown, the two mounting parts 12 can also be arranged in parallel at intervals.

[0111] With such an arrangement, on the one hand, the space between the two mounting parts 12 arranged in a V shape or in parallel at intervals can effectively avoid the teeth, and thus it can be ensured that the two cameras can shoot the teeth from different angles. On the other hand, the space between the two mounting parts 12 arranged in a V shape or in parallel at intervals can also form a weight reduction structure, which is beneficial to reducing the weight of the photographing device 100, and thus is beneficial to facilitating the use of the photographing device 100.

[0112] Further, the photographing device 100 further includes a rotating member, the rotating member is arranged on the main body member, and the rotating member is used to drive the two mounting parts 12 to rotate in different directions, so as to drive the first camera 2 and the second camera 3 to rotate in different directions.

[0113] By rotating the first camera 2 and the second camera 3 in different directions through the rotating member, the shooting range can be expanded. In this way, it is no longer limited to a fixed image acquisition direction, and the image acquisition direction of the camera can be flexibly adjusted according to actual needs to capture more pictures at different positions, which is beneficial to enhancing the adaptability of the photographing device 100 when used in the oral cavity.

[0114] Regarding the rotating member, in this embodiment, the rotating member may include two driving members, the two driving members respectively drive the two mounting parts 12 to rotate in different directions, and the two driving members may be electric cylinders, air cylinders or hydraulic cylinders. This embodiment does not make specific limitations on this. With such an arrangement, to a certain extent, the composition of the rotating member can be simplified, which is beneficial to facilitating the manufacture of the rotating member and its installation on the main body member.

[0115] For the structure of the position-limiting structure 5, in the first implementation, as Figure 4 shown, the position-limiting structure 5 is a positioning shell, and two receiving grooves 53 are provided on the positioning shell. The two receiving grooves 53 respectively accommodate the two mounting portions 12, and the shapes of the two receiving grooves 53 respectively match the shapes of the two mounting portions 12.

[0116] With such a setting, on the one hand, the tight fit between the receiving groove 53 and the mounting portion 12 can enhance the stability of the positioning shell when installed on the mounting bracket 1. In this way, during the shooting process, the shaking of the positioning shell can be effectively prevented, so as to ensure that the camera is always within the optimal shooting distance range, thereby obtaining clear and stable images. On the other hand, it can provide certain protection for the two mounting portions 12, so that during use and storage, the risk of damage to the mounting portions 12 and the camera can be reduced, and the service life of the shooting device 100 can be extended.

[0117] For the structure of the position-limiting structure 5, in the second implementation, as Figure 5 shown, the position-limiting structure 5 is a positioning block, and the positioning block is connected between the two mounting portions 12.

[0118] With such a setting, firstly, by contacting the occlusal surface of the teeth through the positioning surface 51 on the positioning block, not only can the distance between the two cameras and the tooth surface be controlled to ensure that the two cameras are always within the optimal shooting distance range.

[0119] Secondly, since the positioning block is fixedly connected between the two mounting portions 12, the stability of the mounting bracket 1 can be enhanced through the positioning block, which is beneficial to reducing the possible deformation or shaking of the mounting portions 12 during use, so as to ensure that the camera always maintains the correct position and clear images can be taken.

[0120] Thirdly, the positioning block is fixed between the two mounting portions 12, and the distance between the two cameras can be fixed, which is beneficial to ensuring that the field of view angles of the two cameras can effectively cover the target area and avoid mutual interference at the same time.

[0121] For the shooting device 100, further, as Figure 2 shown, the shooting device 100 further includes a first light source 6 and a second light source 7. The irradiation direction of the first light source 6 is the same as the image acquisition direction of the first camera 2, and the irradiation direction of the second light source 7 is the same as the image acquisition direction of the second camera 3. The power supply component is also electrically connected to the first light source 6 and the second light source 7 to supply power to the first light source 6 and the second light source 7.

[0122] The light source is in the same direction as the image acquisition direction of the camera and can provide direct illumination for the shooting area, which can significantly enhance the brightness of the shooting area and make the details of the shooting object more clearly visible.

[0123] Further, as Figure 2 shown, the first light source 6 is annular and sleeved outside the lens of the first camera 2; and / or, the second light source 7 is annular and sleeved outside the lens of the second camera 3.

[0124] The annular light source can provide omnidirectional illumination around the lens of the camera. In this way, no matter from which angle the camera shoots, it can ensure that the shooting object receives uniform light, and there will be no local shadows or uneven illumination.

[0125] In a preferred embodiment, as Figure 2 shown, the first light source 6 is annular and the second light source 7 is also annular. With such a setting, since the first light source 6 and the second light source 7 can respectively provide omnidirectional illumination, it is beneficial to ensure that the objects photographed by the first camera 2 and the second camera 3 receive uniform light.

[0126] For the first light source 6 and the second light source 7, further, the first light source 6 and / or the second light source 7 is used to irradiate light of a specific wavelength onto the surface of the teeth, so that different substances on the tooth surface reflect different fluorescence reactions.

[0127] With such a setting, on the one hand, the light of a specific wavelength can stimulate the fluorescence reaction of different substances on the tooth surface. For dental lesions such as dental caries, cracks and plaque, the substances in these lesion sites have different fluorescence reactions from normal tooth tissues at a specific wavelength. By observing the differences in fluorescence reactions, doctors can more easily discover these potential problems and thus carry out timely intervention and treatment.

[0128] On the other hand, the intensity and color of the fluorescence reaction can reflect the degree of the lesion. By analyzing the changes in the fluorescence reaction, doctors can evaluate the severity of the lesion and provide more specific basis for treatment.

[0129] In a preferred embodiment, both the first light source 6 and the second light source 7 are used to irradiate light of a specific wavelength onto the surface of the teeth. With such a setting, the range of fluorescence reaction on the tooth surface can be expanded, which is beneficial to more comprehensively discover potential problems existing on the teeth and is beneficial to the comprehensive intervention and treatment of the teeth.

[0130] Further, as Figure 1 and Figure 2 shown, the photographing device 100 further includes a filter 8, and the filter 8 is used to filter out light other than the fluorescence reaction. The filter 8 is provided on the lens of the first camera 2, and / or the filter 8 is provided on the lens of the second camera 3.

[0131] The filter 8 can effectively filter out light of non-specific wavelengths and only allow light of specific wavelengths related to the fluorescence reaction to pass through. This can reduce the influence of other light, enhance the intensity of the fluorescence signal, make the fluorescence reaction on the tooth surface more obvious, and thus doctors can clearly observe the fluorescence change, improving the detection and diagnosis accuracy of lesions.

[0132] In a preferred embodiment, as Figure 1 and Figure 2 shown, filters 8 are provided on the lenses of both the first camera 2 and the second camera 3. With this arrangement, light of non-specific wavelengths can be completely filtered out, avoiding the influence of other light, and thus doctors can observe the fluorescence change more clearly.

[0133] Furthermore, the filter 8 is an infrared filter.

[0134] In oral cavity detection, specific fluorescent substances may produce more obvious fluorescence reactions under infrared light excitation, and the infrared filter can effectively filter out visible light and other non-infrared band light, only allowing specific infrared light to pass through. For some fluorescent substances using infrared excitation, using an infrared filter can greatly enhance the intensity of the fluorescence signal, helping doctors detect tooth lesions more accurately.

[0135] Embodiment 2

[0136] This application also provides an oral cavity detection device, as Figure 6 shown. The oral cavity detection device includes a photographing device 100, which has the same structure as the photographing device 100 in any of the above embodiments and can bring the same or similar beneficial effects. For details, reference can be made to the description in the above embodiments, and this embodiment will not be elaborated here.

[0137] In this application, since the image acquisition directions of the first camera 2 and the second camera 3 are set at an angle, the first camera 2 and the second camera 3 in the photographing device 100 have different image acquisition directions. When using the photographing device 100 in this application to photograph the oral cavity, the first camera 2 and the second camera 3 can respectively photograph different positions of the oral cavity from different directions. That is, the first camera 2 and the second camera 3 can photograph different positions of the oral cavity, and thus the photographing device 100 can simultaneously photograph different positions of the oral cavity. Compared with the related art, there is no need to adjust the photographing angle for multiple shootings, which is beneficial to reducing the time consumption and improving the working efficiency of photographing.
