Problems solved by technology

[0004] In the above tooth CBCT image segmentation method, the inventor found that the semi-automatic tooth CBCT image segmentation method can only segment a single tooth at a time, and requires manual operation, and the segmentation time is closely related to the proficiency of the operator. Tooth data takes at least 2-3 hours, and the segmentation speed is relatively slow. In summary, it can be seen that the existing tooth CBCT image segmentation method is inefficient

Abstract

The invention discloses an image segmentation method and device, relates to the technical field of computers, and is invented to solve the problem of low efficiency of the existing tooth CBCT image segmentation method. The method of the present invention comprises: obtaining tooth crown grid data and tooth CBCT image data, and tooth crown grid data and tooth CBCT image data are two different types of three-dimensional data of the same dentition; The CBCT image data is registered to determine the crown area corresponding to each tooth in the tooth CBCT image data; the tooth CBCT image data is segmented according to the crown area to obtain the preliminary three-dimensional area of ​​each tooth; according to the support vector machine SVM algorithm The preliminary three-dimensional region corresponding to each tooth is segmented to obtain the final three-dimensional shape of each tooth. The present invention is suitable for application in the process of orthodontics.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an image segmentation method and device. Background technique [0002] In the field of orthodontics, the anatomical information of the three-dimensional personalized crown and root can be obtained by segmenting the three-dimensional image of the tooth, which can help determine a personalized orthodontic plan. Therefore, 3D image segmentation is very important. [0003] In recent years, with the rapid development of digital technology and computer technology, cone beam computed tomography (CBCT) has been introduced into the field of orthodontics, because CBCT has higher spatial resolution and clearer images , The artifacts are smaller, so it has been widely used in the field of orthodontics, so image segmentation is usually based on CBCT image segmentation. At present, the commonly used tooth-based CBCT image segmentation application software mainly includes: Amira fro...
