[0024] Figure 1 1 is a schematic diagram of the structure of a subgingival image information acquisition system provided according to an embodiment of the present invention. The system comprises: an infrared lighting module 10, an image acquisition module 11, a signal processing module 12 connected to the image acquisition module 11, and a signal transmission module 13 connected to the signal processing module 12; the infrared lighting module 10 comprises an infrared lighting component 101.

[0025] The infrared lighting component 101 is used to start the infrared lighting work when the environment is an information collection environment;

[0026] The image acquisition module 11 is configured to acquire subgingival image information in an oral cavity environment based on the received information acquisition instruction, and send the subgingival image information to the signal processing module 12;

[0027] The signal processing module 12 is configured to receive the subgingival image information sent by the image acquisition module 11, and send the subgingival image information to the signal transmission module 13 when the subgingival image information meets the preset information conditions;

[0028] The signal transmission module 13 is configured to receive the subgingival image information sent by the signal processing module 12 and send the subgingival image information to a display device.

[0029] Wherein, the infrared illumination component includes an infrared lamp. The image acquisition module includes at least one macro camera.

[0030] Before introducing the technical solution, an exemplary description of the application scenario can be given first. The subgingival image information acquisition system disclosed in this embodiment can be deployed on a guiding component with a cylindrical wedge-shaped structure. The guiding component is used to separate the gums and teeth in the oral cavity environment, so as to expose the surface part of the tooth under the gums. A schematic diagram of the guiding component is as Figure 2 shown. Exemplarily, the tip of the guiding component is a passivated spherical surface structure with a diameter of 0.3 mm, which can avoid the situation of injuring the user to be observed during the operation due to the too sharp head. Therefore, when acquiring the subgingival image information, this structure is used to probe down along the part where the gum and the tooth are in contact, so as to avoid discomfort of the user to be observed. In this embodiment, the subgingival image information acquisition system can be deployed at the tip of the guiding component, and the tip is the Figure 2 position corresponding to the dashed box in

[0031] In this embodiment, the infrared illumination component 101 can detect whether the current environment is an information acquisition environment. Exemplarily, the environment is the environment where the infrared illumination component 101 is currently located, and the information acquisition environment may include an oral cavity environment. Specifically, since the light in the oral cavity environment is relatively dim, the brightness value of the environment where the infrared illumination component 101 is located can be detected by a sensor and sent to the signal processing module 12. The signal processing module 12 determines whether the brightness value is lower than a preset brightness threshold. If it is lower than the preset brightness threshold, it can be determined that the infrared illumination component 101 is in the oral cavity environment, establish a connection with the infrared illumination component 101, generate a first working instruction and send the first working instruction to the infrared illumination component 101. After receiving the first working instruction, the infrared illumination component 101 can determine that the environment it belongs to is an information acquisition environment, and then start the infrared illumination work. Alternatively, when the information processing module 12 detects that the infrared control button is triggered, it can generate a second working instruction and send the second working instruction to the infrared illumination component 101. After receiving the second working instruction, the infrared illumination component 101 can determine that the environment it belongs to is an information acquisition environment, and then start the infrared illumination work. By providing a light source for the image acquisition module through the infrared illumination component 101, it helps to improve the quality of the collected image information.

[0032] In a specific implementation, the signal processing module 12 can be connected to an external control. When it detects that the external control is triggered, it can generate an information acquisition instruction for acquiring image information in the oral cavity environment and send it to the image acquisition module 11. After receiving the information acquisition instruction, the image acquisition module 11 starts the information acquisition work and acquires subgingival image information in the oral cavity environment. Exemplarily, the information acquisition instruction includes a video acquisition instruction and a picture acquisition instruction. When the information acquisition instruction is a video acquisition instruction, the subgingival video is acquired through the image acquisition module 11; when the information acquisition instruction is a picture acquisition instruction, the subgingival picture is acquired through the image acquisition module 11.

[0033] Exemplarily, the external control can be a mechanical button, installed on the guiding component, and the start and stop of the image acquisition module 11 and the infrared illumination component 101 are realized by controlling the mechanical button. Exemplarily, when it is detected that the mechanical button is pressed for a first unit time duration, the image acquisition module 11 can be started to take a photo; when it is detected that the mechanical button is pressed for a second unit time duration, the image acquisition module 11 can be started to shoot a video, and when it is detected that the mechanical button is double-clicked, the duration of the video shooting is increased. It should be noted that the second unit time duration is greater than the first unit time duration, and those skilled in the art can set the first unit time duration and the second unit time duration according to the actual application situation, and this embodiment does not make any limitations in this regard.

[0034] In this embodiment, the image acquisition includes a camera group including a macro camera, which can simultaneously acquire subgingival image information of the oral cavity environment at multiple different angles to improve the comprehensiveness and integrity of the acquired information.

[0035] In a specific implementation, after the image acquisition module 11 acquires the subgingival image information, it can send the subgingival image information to the signal processing module 12 for signal processing operations on the subgingival image information. To ensure the validity of the obtained subgingival image information, it can be determined whether the subgingival image information meets the preset information conditions, and the subgingival image information that meets the preset information conditions is used as valid information, and the valid subgingival image information is sent to the signal transmission module 13.

[0036] Optionally, the signal processing module includes: a first information detection unit, which is used to detect whether the pixels of the subgingival image information are greater than the preset minimum pixel standard. If not, it is determined that the subgingival image information does not meet the preset information conditions.

[0037] In a specific implementation, the preset information conditions can be preset pixel conditions. It can be determined whether the subgingival image information meets the preset pixel conditions through the first information detection unit. Specifically, it can be detected whether the pixels of the subgingival image information are greater than the preset minimum pixel standard. Exemplarily, the preset minimum pixel standard includes 1024×1280 pixels. If the pixels of the subgingival image information are greater than 1024×1280 pixels, it is determined that the subgingival image information meets the preset pixel conditions; if the pixels of the subgingival image information are less than or equal to 1024×1280 pixels, it is determined that the subgingival image information does not meet the preset pixel conditions.

[0038] In this embodiment, through the first information detection unit, it is determined whether the pixels of the subgingival image information are greater than the preset minimum pixel standard, thereby screening out the subgingival image information that meets the preset pixel conditions and ensuring the clarity of the subgingival image information.

[0039] Optionally, the signal processing module includes: a second information detection unit, which is used to detect whether the file space occupancy of the subgingival image information is greater than the preset space occupancy threshold. If not, it is determined that the subgingival image information does not meet the preset information conditions.

[0040] In a specific implementation, the preset information condition may be a preset file space occupancy condition. The second information detection unit is used to determine whether the subgingival image information meets the preset file space occupancy condition. Specifically, it can be detected whether the file space occupancy of the subgingival image information is greater than a preset space occupancy threshold. Exemplarily, the preset space occupancy threshold may be 161 kilobytes. If the file space occupancy of the subgingival image information is greater than 161 kilobytes, it indicates that the file space occupancy of the subgingival image information meets the preset file space occupancy condition; if the file space occupancy of the subgingival image information is less than or equal to 161 kilobytes, it indicates that the file space occupancy of the subgingival image information does not meet the preset file space occupancy condition.

[0041] In this embodiment, through the second information detection unit, it is ensured that the file space occupancy of the selected subgingival image information meets the preset file space occupancy condition, so as to select the subgingival image information with a file size meeting the requirements.

[0042] Furthermore, based on information such as the brightness value and chromaticity value of each pixel point of the subgingival image information, it can also be determined whether there is a ghosting situation in the subgingival image information. If there is no ghosting situation, it is determined that the subgingival image information meets the preset information condition; if there is a ghosting situation, it is determined that the subgingival image information does not meet the preset information condition.

[0043] In this implementation, the signal processing module is further configured to, when the subgingival image information does not meet the preset information condition, delete the subgingival image information and generate a re-acquisition instruction to be sent to the image acquisition module to control the image acquisition module to perform an image acquisition operation again.

[0044] For the subgingival image information that does not meet the preset information condition, an information deletion operation can be performed on the subgingival image information to reduce the occupancy of the storage space, and a re-acquisition instruction is generated and sent to the image acquisition module to control the image acquisition module to re-acquire the subgingival image information in the oral cavity environment, and obtain the re-acquired subgingival image information. Determine whether the subgingival image information meets the preset information condition. For the subgingival image information that does not meet the preset information condition, delete it and perform re-acquisition until the subgingival image information that meets the preset information condition is obtained, and save the subgingival image information that meets the preset information condition for transmission and display of the subgingival image information.

[0045] In this embodiment, through the process of deleting the subgingival image information that does not meet the preset information condition and performing re-acquisition, the optimization of the subgingival image information is realized, and the effective subgingival image information that meets the preset information condition is obtained, which is beneficial to improving the accuracy of obtaining the subgingival image information.

[0046] In the technical solution of the embodiment of the present invention, when the infrared illumination component is in an information collection environment, the infrared illumination work is started, so as to avoid poor image collection effect caused by light influence; the image collection module collects the subgingival image information in the oral cavity environment based on the received information collection instruction, and sends the subgingival image information to the signal processing module; thus, the subgingival condition can be viewed without manual visual inspection, and the signal processing module receives the subgingival image information sent by the image collection module. When the subgingival image information meets the preset information conditions, the subgingival image information is sent to the signal transmission module, and the subgingival image information is sent to the display device through the signal transmission module. It solves the problem of unclear viewing caused by obtaining subgingival image information by manual visual inspection, and realizes the effect of improving the accuracy and effectiveness of the obtained subgingival image information.

[0047] Optionally, the subgingival image information acquisition system further includes: a power supply module respectively connected to the infrared illumination module, the image acquisition module, the signal processing module, and the signal transmission module; the power supply module includes a rechargeable battery and a charge and discharge optimization unit; the rechargeable battery is used to supply power to the infrared illumination module, the image acquisition module, the signal processing module, and the signal transmission module respectively, so that the infrared illumination module, the image acquisition module, the signal processing module, and the signal transmission module can work; the charge and discharge optimization unit is used to detect the power of the rechargeable battery, and perform a power adjustment operation on the rechargeable battery when the power exceeds the preset power range.

[0048] Among them, the power adjustment operation includes a charging operation or a discharging operation.

[0049] Specifically, the infrared illumination module, the image acquisition module, the signal processing module, and the signal transmission module can be respectively connected to the power supply module, and the power supply module provides power and performs power adjustment for the infrared illumination module, the image acquisition module, the signal processing module, and the signal transmission module.

[0050] In this embodiment, the power supply module includes a rechargeable battery and a charge and discharge optimization unit. Among them, the rechargeable battery is used to provide power for the module that starts to work when at least one of the infrared illumination module, the image acquisition module, the signal processing module, and the signal transmission module starts to work, so that the module can work normally. During the operation of at least one of the infrared illumination module, the image acquisition module, the signal processing module, and the signal transmission module, the power of the rechargeable battery can be detected by the charge and discharge optimization unit. Specifically, the detection method can be periodic detection, such as detecting once every 5 seconds. When it is detected that the power of the rechargeable battery exceeds the preset power range, it means that the current power of the rechargeable battery cannot meet the module work requirements, and a power adjustment operation can be performed on the rechargeable battery.

[0051] Specifically, the minimum value of the preset power range is the minimum power threshold, and the maximum value of the preset power range is the maximum power threshold. The power supply module further includes a backup battery. When the power of the rechargeable battery is less than the minimum power threshold of the preset power range, the backup battery can be controlled to charge the rechargeable battery to adjust the power of the rechargeable battery within the preset power range. Exemplarily, the minimum value of the preset power range includes 3.9 volts. When the power of the rechargeable battery is greater than the maximum power threshold of the preset power range, the rechargeable battery can be controlled to perform a discharging operation to adjust the power of the rechargeable battery within the preset power range.

[0052] In this embodiment, the power supply module is used to supply power to each module and adjust the power, so that the power of the rechargeable battery is within the preset power range, ensuring the stability and uniformity of the signal emitted when the infrared illumination component is illuminating.

[0053] In this embodiment, the charge and discharge optimization unit is further configured to control the rechargeable battery to stop working when the power is less than the minimum power threshold, generate a charging prompt message and send the charging prompt message to the signal transmission module, so that the signal transmission module feeds back the charging prompt message to the user terminal.

[0054] Specifically, when the power is less than the minimum power threshold, in order to timely prompt the power information for the management of the power of the rechargeable battery, the rechargeable battery can be controlled to stop working when the power of the rechargeable battery is less than the minimum power threshold, avoiding providing unstable voltage for modules such as the infrared illumination module and the image acquisition module; and generating a charging prompt message, sending the charging prompt message to the signal transmission module, and feeding back the charging prompt message to the user terminal through the signal transmission module to prompt the user that the current power of the rechargeable battery is insufficient and charging can be performed, so as to charge the rechargeable battery in a timely and efficient manner and facilitate the user to timely understand the power of the rechargeable battery.

[0055] In this embodiment, the infrared illumination module includes: a collection film component for collecting infrared absorption and reflection data after the infrared light source irradiates the tooth surface and sending the infrared absorption and reflection data to the signal processing module; the signal processing module is further configured to determine the surface information of the tooth surface based on the received infrared absorption and reflection data and send the surface information to the signal transmission module, so that the signal transmission module sends the surface information to the display device.

[0056] Specifically, after the infrared illumination component starts the infrared illumination work, the infrared light irradiates into the oral cavity environment. After being reflected by the tooth surface, infrared absorption and reflection data corresponding to the infrared light are generated. In order to better analyze and understand the tooth conditions in the oral cavity environment, the surface information corresponding to the tooth surface can be determined based on the infrared absorption and reflection data, and the surface information is sent to the signal transmission module, so as to send the surface information to the display device through the signal transmission module, facilitating the user to understand the surface information of the tooth surface in the oral cavity environment through the surface information displayed on the display device.

[0057] In this embodiment, the surface information of the tooth surface is reflected by the infrared absorption and reflection data. By sending the determined surface information of the tooth surface to the display device, the user can view the surface information of the tooth surface through the display device.

[0058] Optionally, the signal transmission module includes a wireless communication module. The wireless communication module includes a Bluetooth module and / or a WiFi module. In a specific implementation, the Bluetooth module and / or the WiFi module can be integrated on the signal transmission control small board, and the subgingival image information is transmitted through a preset communication protocol. In this embodiment, the subgingival image information is transmitted through the wireless communication module, improving the operation convenience during actual image information acquisition.
