Description

Technical Field

[0001] The present invention relates to the technical field of dental image processing, and in particular to an automatic processing method for dental intra-oral and extra-oral photos. Background Art

[0002] Dental photography is of great significance in clinical work. Dentists use photography to obtain photos of patients' faces and oral cavity from different angles, which is of great significance for case data recording, diagnosis analysis, program design, doctor-patient communication, and comparison of pre- and post-treatment efficacy. Obtaining accurate and repeatable facial and intraoral photos is the prerequisite for everything.

[0003] Currently, routine oral photography data mainly include facial photographs and intraoral photographs. Routine facial photographs include: frontal resting photo of the patient, frontal smiling photo of the patient, frontal resting photo of the patient facing 45 degrees to the left, frontal smiling photo of the patient facing 45 degrees to the left, frontal resting photo of the patient facing 90 degrees to the left, frontal smiling photo of the patient facing 90 degrees to the left, frontal resting photo of the patient facing 45 degrees to the right, frontal smiling photo of the patient facing 45 degrees to the right, frontal resting photo of the patient facing 90 degrees to the right, and frontal smiling photo of the patient facing 90 degrees to the right, a total of 10 photos; routine intraoral photographs include: frontal occlusal photo when cusps are misaligned, left buccal occlusal photo, right buccal occlusal photo, upper dental arch occlusal photo, lower dental arch occlusal photo, right side 90-degree overbite coverage photo of the anterior teeth area, and frontal upward 45-degree overbite coverage photo of the anterior teeth area, a total of 7 photos.

[0004] Among them, among the above-mentioned conventional intraoral photos, the upper dental arch occlusal photos and the lower dental arch occlusal photos can only be taken with a reflector due to angle restrictions, and the resulting images need to be manually flipped later before they can be used correctly. In addition, since multiple intraoral and extraoral photos of patients taken at various angles / parts often have incorrect shooting angles, different sizes, proportions, and heights of the main body of the photo content, and a large proportion of invalid information, dentists need to perform a large amount of manual rotation and cropping of the photo data of each patient in the later stage, which is not only time-consuming (it takes an average of 8-10 minutes for doctors to process intraoral and extraoral photos of each patient / each visit), but also prone to human errors and mistakes (common examples include the inability to accurately correct facial photos to make the pupil line parallel to the ground, the upper dental arch occlusal photos and the lower dental arch occlusal photos not correctly flipped, and the patient's name and shooting date not recorded), which seriously affects the accuracy of diagnosis and treatment, and even makes it difficult to ensure the uniformity of the angles, sizes, and proportions of intraoral and extraoral photos of patients in the same period or even different periods, which seriously hinders the recording of oral disease case data, diagnosis and analysis, program design, doctor-patient communication, and comparison of pre- and post-treatment efficacy.

[0005] In addition, when the patient's oral and intraoral photos are used for diagnosis, doctors often need to use additional tools to make auxiliary lines and perform measurements, which is time-consuming and laborious, and the accuracy of visual inspection alone is greatly reduced. Finally, the oral and intraoral photos processed by the doctor need to be additionally created, drawn, and arranged into JPG, TIF, DOC, PPT or PDF format files for the production of electronic medical records and teaching presentations, etc. The process is cumbersome and inefficient. If the patient's oral and intraoral photos can be automatically and accurately processed and cropped, and common diagnostic information can be automatically generated, and JPG, TIF, DOC, PPT or PDF format files can be automatically created, it will be of great significance to improve the efficiency and accuracy of dentists' diagnosis and treatment, and indirectly benefit the majority of oral patients.

[0064] The following describes in detail the automatic processing method for dental intra-oral and extra-oral photographs according to an embodiment of the present invention with reference to the accompanying drawings.

[0065] Reference Figures 1 to 16 As shown, the method for automatically processing dental intraoral and extraoral photos provided in an embodiment of the present invention comprises the following steps:

[0066] S1. Take and select multiple facial and oral photos of the patient from different angles according to the oral photography standards;

[0067] Specifically, in this technical solution, step S1 specifically includes:

[0068] S11. Take multiple photos of the patient's face from different angles and the inside of the oral cavity from different angles according to the oral photography standards;

[0069] S12. Based on each shooting angle, select a plurality of facial photos of the patient with different shooting angles and a plurality of intraoral photos with different shooting angles.

[0070] It should be noted here that in the above step S1, multiple facial photos and intraoral photos taken from each shooting angle will be taken, so that the photos taken from each shooting angle with high shooting resolution and obvious facial and / or intraoral features can be selected as the photos that need to be processed. In this process, unnecessary photos that are not selected can be deleted.

[0071] Among them, the selected multiple facial photos with different shooting angles specifically include: a frontal resting photo of the patient (a frontal photo of the patient's face with his mouth naturally closed in a resting state), a frontal resting photo of the patient facing 45 degrees to the left (a photo of the patient's face facing 45 degrees to the left with his mouth naturally closed in a resting state), a frontal resting photo of the patient facing 45 degrees to the right (a photo of the patient's face facing 45 degrees to the right with his mouth naturally closed in a resting state), a frontal resting photo of the patient facing 90 degrees to the left (a photo of the patient's face facing 90 degrees to the left with his mouth naturally closed in a resting state), and a frontal resting photo of the patient facing 90 degrees to the right (a photo of the patient's face facing 90 degrees to the right with his mouth naturally closed in a resting state) , a frontal smiling photo of the patient (a frontal photo of the patient's face with his mouth open and his teeth naturally occluded in a smiling state), a frontal smiling photo of the patient facing 45 degrees to the left (a photo of the patient's face facing 45 degrees to the left with his mouth open and his teeth naturally occluded in a smiling state), a frontal smiling photo of the patient facing 45 degrees to the right (a photo of the patient's face facing 45 degrees to the right with his mouth open and his teeth naturally occluded in a smiling state), a frontal smiling photo of the patient facing 90 degrees to the left (a photo of the patient's face facing 90 degrees to the left with his mouth open and his teeth naturally occluded in a smiling state), and a frontal smiling photo of the patient facing 90 degrees to the right (a photo of the patient's face facing 90 degrees to the right with his mouth open and his teeth naturally occluded in a smiling state).

[0072] It can be seen that the multiple facial photos of patients taking dental visits according to the oral photography specifications specifically include the 10 facial photos mentioned above. Figure 6 shown.

[0073] In addition, the selected multiple intraoral photographs with different shooting angles specifically include: frontal occlusal photograph when the cusp is in an interdigitated position (a frontal photograph of the mouth when the mouth is open and the upper and lower teeth are naturally interdigitated and fully exposed), left buccal occlusal photograph when the cusp is in an interdigitated position (a frontal photograph of the mouth facing 45 degrees to the left when the mouth is open and the upper and lower teeth are naturally interdigitated and fully exposed), right buccal occlusal photograph when the cusp is in an interdigitated position (a frontal photograph of the mouth facing 45 degrees to the right when the mouth is open and the upper and lower teeth are naturally interdigitated and fully exposed), upper dental arch occlusal photograph (a frontal photograph of the mouth when the mouth is open and the upper and lower teeth are naturally interdigitated and fully exposed). A 45-degree frontal upward shot of the mouth with the upper teeth fully exposed), a 45-degree frontal downward shot of the lower dental arch (a shot of the mouth facing downward at 45 degrees with the mouth open and the upper and lower teeth naturally open to fully expose the lower teeth facing downward), a 90-degree overbite and coverage shot of the right side of the anterior teeth (a shot of the mouth facing right at 90 degrees with the mouth open and the upper and lower teeth naturally staggered to occlude to fully expose the left sides of the upper and lower teeth), and a 45-degree frontal upward upward shot of the anterior teeth (a shot of the mouth facing upward at 45 degrees with the mouth open and the upper and lower teeth naturally staggered to occlude to fully expose the upper and lower teeth).

[0074] It can be seen that the multiple intraoral photos taken according to the oral photography specifications of the patient's dental treatment specifically include the 7 intraoral photos mentioned above. Figure 6 shown.

[0075] S2. Opening a software interface having a patient information input column and a photo classification placement column, inputting patient information in the patient information input column, and dragging the selected multiple photo classifications into different photo classification placement columns;

[0076] Furthermore, in the present technical solution, the patient information in step S2 at least includes the patient's name, the time when the patient's corresponding photo was taken, and the diagnosis remarks.

[0077] From the above, it can be clearly seen that the patient-related information is associated with the multiple facial photos and the multiple intraoral photos so as to avoid mistakes.

[0078] And in the present technical solution, the photo classification placement column in step S2 includes a facial photo placement column and an intraoral photo placement column;

[0079] Based on this, in this embodiment, multiple facial photos of patients visiting the dentistry taken according to the oral photography specifications are dragged into the facial photo placement column for archiving; multiple intraoral photos of patients visiting the dentistry taken according to the oral photography specifications are dragged into the intraoral photo placement column for archiving. For details, refer to Figure 7 shown.

[0124] From the above, it can be concluded that the automatic processing method for dental intraoral and extraoral photos provided by the present application, during specific implementation, the dentist enters the patient information in the software interface, including the patient's name, the time when the patient's corresponding photos were taken, and the diagnosis notes, and manually drags the multiple facial and intraoral photos of the patient taken and selected according to the oral photography specifications into the corresponding photo classification placement column. Then, the software program can be used to automatically rotate the multiple facial and intraoral photos of the patient selected from different angles so that they are all rotated to the correct direction, and then they are all cropped into intraoral and extraoral photos of different parts of the mouth that are proportional in size to the content of the photos in accordance with the oral photography specifications, and finally through The software program automatically generates commonly used dental diagnostic auxiliary lines according to facial and / or oral landmarks and rotation reference lines, and calculates commonly used diagnostic values. The software program also creates an electronic review document named after the patient information, and stores the generated multiple target photos A and target photos B in the electronic review document according to arrangement requirements. The related operations are quick and time-saving, which can greatly shorten the time for dentists to organize relevant information of patients' oral and extraoral photos. All photos are processed in a unified format, which can facilitate comparison of information of the same patient or even different patients in the future, and common export formats can be selected for computer display or printing, so as to facilitate post-production of patient electronic medical records or sharing.

[0125] Furthermore, the present application is indeed highly practical and has good effects. It can effectively solve the problems of time-consuming and labor-intensive processing of oral doctors in organizing relevant information of patients' oral and intraoral photos, which makes the present application have good market promotion value. The present application will be very popular and will surely be widely popularized in the oral departments of major hospitals and major oral medical clinics on the market.

[0126] It should be further added that, in specific implementation, for individual patients, when there are requirements for taking photos inside and outside the mouth from other shooting angles, rotation and cropping, this application can be further upgraded and optimized to meet higher usage requirements.
