Description

TECHNICAL FIELD

[0001] The application relates to the technical field of oral cavity instruments, in particular to a novel oral cavity scanning device capable of stretching and bending and high-definition rapid capturing. BACKGROUND

[0002] With the popularization of digital oral diagnosis and treatment technology, oral cavity scanning devices have become the core tools for dental diagnosis, restoration body design and orthodontic treatment. Traditional impression methods are gradually being replaced by digital scanning due to complex operation, poor patient experience and easy human interference. However, the existing oral cavity scanning devices still have many technical bottlenecks, such as low scanning efficiency, insufficient adaptability and the like, which affect their widespread promotion and use efficiency in clinical application.

[0003] Firstly, the mechanical structure of the existing oral scanning device is rigid: the existing device mostly adopts a fixed form scanning head, and the flexibility is poor. Especially in the posterior tooth area, deep groove and complex dentition area, the scanning head is difficult to effectively fit the tooth surface, resulting in difficulty in data acquisition in some areas. The doctor needs to frequently adjust the device angle or the patient's body position to cover the complete scanning range as much as possible, which not only increases the operation difficulty, but also prolongs the scanning time, affecting the diagnosis and treatment efficiency.

[0004] Secondly, the existing oral scanning device has poor environmental adaptability: the internal environment of the oral cavity is complex and changeable, and factors such as the humidity, illumination condition and temperature of the oral cavity of different patients will affect the scanning imaging quality. The traditional device cannot adapt to the dynamic changes of the humidity, temperature and illumination in the patient's oral cavity due to the use of fixed light source and exposure parameters, resulting in frequent problems such as blurred imaging and data loss. Especially in uneven light or high humidity environment, repeated scanning is needed to make up for the defects of image quality, which further restricts the practicability of the device.

[0005] Thirdly, the existing oral scanning device has low efficient path planning: most of the current oral scanning devices rely on fixed scanning paths or manual adjustment of scanning tracks by doctors. This way often fails to ensure the completeness of data acquisition when facing complex dentition or limited oral cavity space. Fixed path is easy to cause repeated scanning in some areas, while manual adjustment of path by doctors depends on personal experience, which is low in efficiency and easy to miss key parts. For scenes requiring fine three-dimensional modeling, such as implant guide plate design and invisible orthodontic scheme formulation, this unstable scanning method cannot guarantee high-quality digital data acquisition.

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see the appendix Figure 1 -Appendix Figure 2 This invention provides a novel high-definition, rapid-capture oral scanning device with a telescopic and bendable design, comprising a housing 1, one end of which is connected to a cavity area housing 2, and the other end of the cavity area housing 2 is fixed to a telescopic cavity housing 3. A movable rod 6 is slidably disposed inside the telescopic cavity housing 3. One end of the movable rod 6 is fixed to a push plate 8, and the other end is connected to a drive assembly. Through the coordinated control of the dual motors of the drive assembly, the telescopic and multi-angle bending adjustment of the oral scanning head 11 is realized. A spring 7 is connected to the outer wall of the push plate 8. The spring 7 is internally sleeved on the outside of the moving rod 6. The outside of the push plate 8 is set inside the telescopic cavity shell 3. The telescopic cavity shell 3 and the cavity area shell 2 are internally connected. The outer wall of the push plate 8 is attached to the inner wall of the telescopic cavity shell 3. The shell 1 and the cavity area shell 2 are not connected. The output end of the drive component is connected to the oral scanning head 11. An output component is set inside the shell 1, which is used to control the movement of the push plate 8 inside the telescopic cavity shell 3 and to control the telescopic adjustment of the oral scanning head 11. A handle 17 is set on the outer wall of the shell 1. A control switch component is set on the shell 1 and the handle 17. A connecting line 20 is set on the handle 17, which is used to connect an external display device. A main unit is set inside the shell 1 and the handle 17. The main unit is connected to the connecting line 20. The processor in the main unit is equipped with an intelligent oral scanning AI system. A detection component is set at the end of the oral scanning head 11.

[0051] Specifically, upon startup, the main unit inside housing 1 enters working mode, and the intelligent oral scanning AI system is immediately loaded. The doctor holds the handle 17, lightly presses the control switch, and the connection cable 20 simultaneously activates the external device, establishing a data link and illuminating the display interface.

[0052] The push plate 8 awaits command, while the moving rod 6 remains stationary. Pressing the telescopic control button 19 activates the air pump 4, rapidly filling the cavity housing 2 with air. The increased internal pressure causes the push plate 8 to move forward, and the moving rod 6 slides accordingly, slowly compressing the spring 7 within the telescopic cavity housing 3. The scanning head 11 gradually penetrates, entering the working area.

[0053] If angle adjustment is required, the drive component intervenes. A command is issued by the rotation control button 18, motor 10 responds, and the thrust is transmitted to the adapter mechanism, causing the oral sweep head 11 to deflect. For further adjustment, press the switch button 21, motor 23 starts, and the bending angle is precisely controlled to ensure adaptation to complex oral cavity structures.

[0054] During scanning, all detection components operate simultaneously. Camera 12 continuously acquires images, lamp 13 provides illumination, and light sensor 14 detects ambient brightness and automatically adjusts the light source output. Temperature and humidity sensor 15 monitors the oral cavity environment and optimizes imaging parameters in real time. Pressure sensor 16 senses the contact between the oral scanner head 11 and oral tissues to ensure smooth scanning.

[0055] After the scan is completed, release the telescopic control button 19. The air pump 4 stops running, and the air pressure inside the cavity shell 2 drops. The spring 7 releases its compression force, the push plate 8 moves back, and the moving rod 6 retracts to its initial position. The scanning head 11 then resets, and the equipment enters standby mode.

[0056] It should be noted that the part of the oral scanning head 11 that comes into contact with the oral cavity is made of silicone material, which ensures that the oral scanning head 11 will not cause oral damage when it comes into contact with the oral cavity during operation.

[0057] Please see the appendix Figure 4 The drive assembly includes a mounting cavity 9, one end of which is connected to the other end of a moving rod 6. A motor 10 is installed inside the mounting cavity 9. The output end of the motor 10 is connected to a transition cavity 22. The end of the transition cavity 22 is rotatably connected to the other end of the mounting cavity 9. A motor 23 is installed inside the transition cavity 22. The output end of the motor 23 is connected to an oral sweeping head 11. The end of the oral sweeping head 11 is rotatably connected to the other end of the transition cavity 22.

[0058] Specifically, when motor 10 starts, power is transmitted along the output end, and the adapter housing 22 rotates accordingly, while the mounting housing 9 provides stable support. The end of the adapter housing 22 rotates flexibly, maintaining a smooth connection with the mounting housing 9, and the movement trajectory is precise and controllable.

[0059] Motor 23 is activated upon command, and its output shaft pulls the scanning head 11, adjusting its angle and gradually bending it. The end of the scanning head 11 rotates in a controlled manner, closely adhering to the other end of the adapter cavity 22. It responds quickly to angle changes, adapting to scanning at different positions.

[0060] Motor 10 and Motor 23 work together to drive the adapter cavity shell 22 and the oral scanning head 11 to adjust synchronously, rotating and bending alternately to stably adapt to the oral cavity environment.

[0061] Please see the appendix Figure 2 The detection component includes a camera 12, which is located at the center of the end of the mouth scanner 11. Multiple lamps 13 are provided at the end of the mouth scanner 11 and are arranged in a ring outside the camera 12. A light sensor 14, a temperature and humidity sensor 15, and a pressure sensor 16 are arranged sequentially from bottom to top on the outer wall of the mouth scanner 11.

[0062] Specifically, camera 12 is activated, and the end of the scanning head 11 is finely adjusted for positioning, locking the field of view. The lamps 13 are sequentially lit in a ring, with staggered beams projected for dynamic brightness balance. Camera 12 captures the image, and the data flows into the processing unit, where details are clarified frame by frame.

[0063] The light sensor 14 monitors the light intensity in real time and adjusts accordingly, while the lamp tube 13 adapts to the output, ensuring uniform and stable illumination. The temperature and humidity sensor 15 detects subtle changes in the air quality; as parameters fluctuate, the system compensates in real time, precisely optimizing the imaging environment.

[0064] Pressure sensor 16 is attached to the outer wall; a tiny contact force triggers feedback, allowing for real-time sensing and data transmission to prevent excessive pressure and ensure smooth operation of the device. Camera 12, lamp 13, light sensor 14, temperature and humidity sensor 15, and pressure sensor 16 each perform their respective functions, working together to accurately capture details inside the oral cavity.

[0065] Please see the appendix Figure 3 The output component includes an air pump 4, which is externally disposed inside the housing 1. One end of the air pump 4 is connected to an air pipe 5, and the other end of the air pipe 5 passes through the cavity area 2 in the middle of the housing 1.

[0066] Specifically, air pump 4 starts, airflow surges, internal turbine rotates at high speed, and pressure rises sharply. Air pipe 5 carries the airflow; the channel is narrow and long, and the air pressure increases in layers. The other end of air pipe 5 leads directly to the middle of shell 1, and the airflow penetrates and enters the cavity shell 2.

[0067] The air pressure inside the cavity shell 2 increases, the thrust diffuses, and the force on the inner wall of the cavity is uniform. The air pump 4 operates continuously, with alternating airflow pulses, and the power is released steadily. The air tube 5 vibrates slightly, the flow rate is adjusted, the airflow is precisely delivered, and the internal space of the cavity shell 2 is stably filled.

[0068] When air pump 4 stops, the airflow slowly retreats, the pressure drops, the gas inside the cavity shell 2 is gradually released, and the system returns to its initial equilibrium.

[0069] Please see the appendix Figure 1 and attached Figure 4 The control switch component includes a rotary control button 18, a telescopic control button 19, and a connecting wire 20. The rotary control button 18 and the telescopic control button 19 are both externally mounted on the handle 17, and are used to control the device to start bending rotation and scanning, respectively. The connecting wire 20 is externally mounted on the housing 1, and is used to control the start of the output component.

[0070] Specifically, when the rotation control button 18 is pressed, a signal is transmitted instantaneously, and a current pulse triggers the command. The motor 10 responds, driving the rotation, and the scanning head 11 adjusts accordingly, allowing for flexible and precise angle changes.

[0071] A light touch of the telescopic control button 19 provides rapid feedback, simultaneously activating the mechanical system. The push plate 8 moves forward, the moving rod 6 extends, and the scanning head 11 slowly advances, penetrating deeper into the scanning area. Releasing the button reverses the movement, returning the device to its original position, and the equipment resets to standby.

[0072] Connector 20 rests on the surface of housing 1, through which pulse signals travel, ensuring seamless command transmission. Air pump 4 is activated under control, causing a sudden surge of airflow and a rise in pressure inside the cavity of housing 2. The command from connector 20 terminates, the output components cease operation, the system returns to equilibrium, and awaits the next operation.

[0073] Please see the appendix Figure 5 The intelligent oral cavity scanning AI system includes:

[0074] A high-definition image processing module is used to optimize and enhance scanned images in real time;

[0075] The intelligent path planning module is used to dynamically adjust the scanning path;

[0076] An environment adaptive module is used to adjust scanning parameters according to ambient light, temperature, and humidity conditions.

[0077] The wireless data transmission module is used to transmit scan data to a remote storage system or a doctor's terminal;

[0078] Augmented reality interaction module, used to display scanning progress and feedback in real time.

[0079] Specifically, in this embodiment, the high-definition image processing module is mainly used to optimize the raw image data collected by the oral scanning head 11 to ensure that the final generated three-dimensional oral cavity model has higher resolution and more refined details.

[0080] Specifically, the high-definition image processing module consists of an image denoising unit, an image enhancement unit, and a 3D reconstruction unit, with each unit working together to process image information.

[0081] The image denoising unit first performs noise reduction processing on the image data acquired by the camera 12 to reduce noise caused by light interference or scanning motion. In some embodiments, this unit works in conjunction with the light sensor 14 to dynamically adjust the filtering intensity to adapt to different lighting conditions.

[0082] The image enhancement unit improves image sharpness, brightness, and contrast. During scanning, this unit adjusts imaging parameters based on feedback from the environment adaptation module to ensure the acquired image remains stable under different environmental conditions.

[0083] The 3D reconstruction unit and the intelligent path planning module work together to automatically stitch together the frames after a complete scan by the intraoral scanning head 11, reconstructing a complete 3D oral cavity model. After the data is transmitted to the host computer, the system uploads the 3D model to the doctor's terminal via the wireless data transmission module for further analysis.

[0084] In actual operation, the high-definition image processing module and the environment adaptation module are closely integrated to adjust imaging parameters in real time, ensuring stable and reliable oral scan results.

[0085] In this embodiment, the intelligent path planning module is mainly used to optimize the movement path of the intraoral scanning head 11 inside the oral cavity, so as to reduce redundant scanning and improve the overall scanning efficiency. This module comprehensively considers the oral anatomical structure, obstacles that may occur during the scanning process, ambient lighting conditions, and scanning path optimization strategies to ensure that the device completes high-quality oral 3D data acquisition in the shortest possible time.

[0086] Specifically, the intelligent path planning module includes a path optimization unit, an obstacle detection unit, and a dynamic adjustment unit. These units work together to achieve efficient path planning and real-time adjustment.

[0087] The path optimization unit is used to calculate the optimal scanning route to minimize scanning time and improve the continuity and accuracy of data acquisition.

[0088] In this embodiment, the unit employs the A(A-star) algorithm for path search. This algorithm determines the optimal path by comprehensively considering the actual cost of the explored paths and the estimated cost of the remaining paths. Its estimation function is as follows:

[0089] f(n) = g(n) + h(n);

[0090] in,

[0091] f(n) represents the total cost of the current node n;

[0092] g(n) represents the actual cost from the starting point to the current node, which is usually determined by factors such as the length of the scan path, scan time, or energy consumption.

[0093] h(n) represents the estimated shortest remaining path cost from the current node n to the target node, which is usually calculated using Euclidean distance or Manhattan distance:

[0094]

[0095] in,

[0096] (x n ,y n ,z n () represents the coordinates of the current scan point;

[0097] (x t ,y t ,z t ) represents the coordinates of the target scanning point.

[0098] In some embodiments, in order to improve the efficiency of path optimization, a dynamic weight adjustment mechanism can be introduced to adjust g(n) and h(n) based on real-time environmental parameters (such as scanning progress, local complexity of the oral cavity, etc.) to optimize the path search process.

[0099] The obstacle detection unit is used to identify possible obstructions during the scanning process, such as movement of oral soft tissues, saliva, and other interfering factors, and adjust the scanning path accordingly.

[0100] In this embodiment, the unit uses an optical depth sensor combined with real-time point cloud analysis to identify obstacles. The obstacle detection judgment formula is as follows:

[0101]

[0102] in,

[0103] D(x,y) is the Euclidean distance between the scan point and the preset standard point;

[0104] (x t ,y t ,z t ) represents the coordinates of the target scan point, i.e., a point on the ideal scan path;

[0105] (X r ,Y r Z r ) represents the currently detected point cloud coordinates. If D(x,y) exceeds the preset threshold, the point is considered to be occluded.

[0106] Alternatively, the unit can also incorporate deep learning models (such as YOLO or CNN) for obstacle recognition to improve detection accuracy and adaptability. For example, in some embodiments, the device can use images captured by camera 12 for real-time target detection and identify potential obstacles, such as moving tissues like the tongue and gums, using a trained neural network model.

[0107] The dynamic adjustment unit is used to optimize the scanning path in real time according to changes in the scanning environment, ensuring that the movement trajectory of the oral scanning head 11 in the oral cavity always conforms to the optimal strategy.

[0108] In this embodiment, the unit employs reinforcement learning (RL) combined with the Q-learning algorithm for dynamic path adjustment. Specifically, the Q-learning formula is as follows:

[0109] Q(s,a)=Q(s,a)+α[r+γamxq(s′,a′)-Q(s,a)];

[0110] in,

[0111] Q(s,a) is the value of taking action a in state s;

[0112] α is the learning rate, which controls the update step size;

[0113] r is the current reward value. If the scan path is shorter or redundant scans are reduced, the reward value will increase.

[0114] γ is a discount factor that determines the degree of influence on future rewards;

[0115] s ' For the next state, a ′ This is a possible next step.

[0116] In one possible implementation, the unit can train a Q-learning model based on historical scan data, enabling the system to gradually learn the optimal scan path, reduce unnecessary repeated movements, and improve scanning efficiency.

[0117] In some embodiments, the unit can also perform path correction by combining real-time environmental sensor data. For example, when the light sensing unit detects insufficient light in a certain area, the system can adjust the scanning order, first scanning the well-lit area and appropriately increasing the brightness of the lamp 13, and then returning to the poorly lit area to complete the scanning.

[0118] In this embodiment, the environment adaptive module is mainly used to monitor and adjust the scanning environment parameters to ensure that factors such as light, temperature and humidity during the scanning process do not affect the final image quality.

[0119] Specifically, the module includes a light sensing unit, a humidity control unit, and a temperature monitoring unit.

[0120] The light sensing unit works in conjunction with the lamp tube 13 on the oral scanner 11. When the camera 12 is acquiring images, it senses the lighting conditions inside the oral cavity and adjusts the brightness of the lamp tube 13 to ensure that the imaging light source is evenly distributed and to avoid overexposure or insufficient lighting.

[0121] The humidity control unit primarily utilizes feedback information from the temperature and humidity sensor 15 to optimize the exposure time and image processing parameters of the camera 12. If the humidity inside the oral cavity is high, this unit will adjust the scanning rhythm of the oral scanner 11 to prevent moisture from affecting the scanning quality. In some embodiments, this unit can cooperate with the intelligent path planning module to ensure that the scanning path avoids high-humidity areas, thereby improving image quality.

[0122] The temperature monitoring unit primarily detects temperature changes inside the scanning head 11 and housing 1 to prevent overheating during prolonged operation. During extended scanning, this unit sends temperature data back to the host computer, which adjusts the scanning power based on this feedback to prevent unstable imaging or equipment damage due to overheating.

[0123] Throughout the scanning process, the environment adaptation module and the high-definition image processing module work together to ensure that the scanned images maintain high quality under various environmental conditions.

[0124] In this embodiment, the wireless data transmission module is mainly used to transmit the collected scan data to a remote storage system or a doctor's terminal for real-time analysis and diagnosis.

[0125] This module connects to the host computer and communicates with an external display device or wireless network via connection cable 20. After data acquisition, the system compresses and encodes the image information and transmits it via high-speed wireless signals. In some embodiments, to reduce data transmission latency, this module employs edge computing technology to perform preliminary processing of the scanned data within the host computer before transmission.

[0126] The wireless data transmission module works closely with the high-definition image processing module to ensure that high-definition scan data is transmitted in the optimal format. In some embodiments, doctors can view the scan progress in real time through a remote terminal and directly manipulate the data, such as zooming, rotating, and annotating, to improve diagnostic efficiency.

[0127] In addition, this module can also work in conjunction with the environment adaptation module. For example, when the network signal is detected to be unstable, the system will automatically adjust the transmission rate to prevent data loss or transmission interruption.

[0128] In this embodiment, the augmented reality interaction module is mainly used to provide real-time feedback during the scanning process, ensuring that doctors can keep track of the scanning progress at any time and perform necessary interactive operations.

[0129] Specifically, the module includes a real-time display unit, a virtual annotation unit, and a 3D interactive feedback unit.

[0130] The real-time display unit transmits the image data collected by the oral scanning head 11 to an external display device or doctor's terminal in real time, enabling doctors to observe the internal structure of the oral cavity during the scanning process and adjust the scanning strategy at any time.

[0131] The virtual annotation unit allows doctors to annotate scanned images to mark lesions, record abnormal areas, or plan treatment. In some embodiments, this unit can work with a wireless data transmission module to synchronize the annotation information to a telemedicine system for reference by other medical personnel.

[0132] The 3D interactive feedback unit, combined with the scanning path data from the intelligent path planning module, provides three-dimensional visualization feedback, enabling doctors to view the scanning progress from different angles and make real-time adjustments to the movement trajectory of the oral scanning head 11.

[0133] This module works closely with the wireless data transmission module and the high-definition image processing module to ensure that doctors can obtain the most intuitive and real-time scan feedback in an augmented reality environment.

[0134] Throughout the entire operation of the intelligent oral cavity scanning AI system, the various modules collaborate with each other to form a complete working loop.

[0135] First, the intelligent path planning module analyzes the oral cavity structure, calculates the optimal scanning path, and controls the movement of the oral scanning head 11.

[0136] During the scanning process, the high-definition image processing module receives image data acquired by the camera 12 and performs noise reduction, enhancement, and 3D reconstruction. Simultaneously, the environment adaptation module monitors light intensity, temperature, and humidity, and adjusts relevant parameters in real time to optimize the scanning results.

[0137] The wireless data transmission module is responsible for transmitting the collected data to a remote terminal, enabling doctors to view the scanning progress in real time and use the augmented reality interaction module to perform interactive operations on the scanned images, such as zooming, rotating, and annotating.

[0138] Ultimately, after processing and transmission, the high-definition scan data can generate a high-precision three-dimensional oral model, which doctors can use for further diagnosis and treatment planning.

[0139] Throughout the system's operation, the various modules complement each other, ensuring that the oral scanning equipment can maintain a stable and efficient working state under different environmental conditions, and providing doctors with intuitive and accurate three-dimensional images of the oral cavity.

[0141] The image denoising unit is used to remove noise from the scanned image and optimize the image quality.

[0142] Image enhancement unit, used to improve image contrast, brightness and sharpness;

[0143] The 3D reconstruction unit is used to convert scanned data into a complete 3D oral cavity model.

[0144] Please see the appendix Figure 7 The intelligent path planning module includes:

[0145] The path optimization unit is used to calculate the optimal scan route and reduce scan time.

[0146] An obstacle detection unit is used to identify any obstructions that may occur during the scanning process;

[0147] The dynamic adjustment unit is used to optimize the path in real time according to changes in the scanning environment.

[0148] Please see the appendix Figure 8 The environment adaptive module includes:

[0149] A light-sensing unit is used to detect ambient light during scanning and adjust the light source.

[0150] A humidity control unit is used to optimize imaging parameters based on changes in oral cavity humidity.

[0151] The temperature monitoring unit is used to monitor the operating temperature of the equipment to prevent overheating from affecting the scanning quality.

[0152] Please see the appendix Figure 9 The augmented reality interaction module includes:

[0153] A real-time display unit is used to display intraoral imaging results in real time during the scanning process, improving the visibility of the operation;

[0154] Virtual annotation units are used to annotate key areas on scanned images to assist doctors in diagnosis;

[0155] The 3D interactive feedback unit provides real-time three-dimensional visualization feedback, enabling doctors to adjust their scanning strategies in an augmented reality environment.

[0156] The intelligent navigation unit provides scanning guidance based on AI analysis, optimizes the scanning path, and reduces operational errors.

[0157] Working principle: After startup, the main unit is powered on, and all sensors enter standby mode. An external display device can be connected via cable 20 for easy viewing of data and images. When the doctor presses the control switch, the oral scanner 11 starts immediately.

[0158] When the user inserts the oral scanning head 11 into the patient's oral cavity, in order to facilitate the scanning and viewing of the oral cavity contents, the user can hold the handle 17 and press the rotation control button 18 or the telescopic control button 19 to control the adjustment of the oral scanning head 11 in the oral cavity.

[0159] During the scanning process, the intelligent path planning module begins analysis. The device assesses the oral cavity structure and calculates the optimal scanning route. When the intraoral scanning head 11 needs to be extended or retracted, the extension control button 19 can be pressed to start the air pump 4, which inputs gas into the cavity housing 2 through the air tube 5, thereby pushing the push plate 8 to move within the extension cavity housing 3. At the same time, the push plate 8 compresses the spring 7, and the moving rod 6, pushed by the push plate 8, moves the intraoral scanning head 11. If retraction is required, simply stop pressing the extension control button 19. As the gas in the cavity housing 2 decreases, the synchronous spring 7 rebounds, causing the push plate 8 to move back, thereby moving the moving rod 6 to move the intraoral scanning head 11 back.

[0160] When the oral scanning head 11 needs to rotate, simply press the rotation control button 18 to start the motor 10, which in turn drives the adapter housing 22 to rotate, thereby controlling the oral scanning head 11 to scan different positions of the oral cavity. If the oral scanning head 11 needs to be bent, press the switch button 21 to start the motor 23, which drives the oral scanning head 11 to continue rotating, thereby completing the bending angle adjustment of the oral scanning head 11. With the cooperation of the motor 10 and the motor 23, the position adjustment of the oral scanning head 11 in the oral cavity can be more flexibly controlled to adapt to the oral environment.

[0161] During the scanning process, the high-definition camera 12 operates synchronously with the structured light projection. The camera 12 continuously captures images, while the lamp 13 emits light beams in real time, recording changes in reflection. Point cloud data is rapidly generated, and AI algorithms optimize in real time, removing noise and improving clarity. The light sensing unit continuously monitors the ambient brightness and adjusts the light source to ensure optimal imaging results.

[0162] The humidity and temperature sensor 15 provides real-time feedback. If excessive oral humidity is detected, the system adjusts optical parameters to prevent blurred imaging. The pressure sensor 16 senses the contact force between the oral scanning head 11 and the tissue; if it is too high, the device automatically reduces pressure to minimize patient discomfort.

[0163] The augmented reality interaction module provides visual feedback at any time. Doctors can view 3D models on the screen and annotate key areas in real time. If the scanning path deviates, the intelligent navigation unit quickly corrects it, suggesting the optimal direction of movement, reducing repeated scans and improving efficiency.

[0164] After data acquisition, AI algorithms process the scan results. The 3D reconstruction units stitch the images together to generate a complete oral cavity model. The wireless data transmission module then activates, automatically uploading the data to the cloud or the doctor's terminal for further analysis. The entire process is precise and efficient, ensuring that every detail is captured accurately.
