Tooth segmentation method and device based on CBCT (Cone Beam Computed Tomography) and electronic equipment

The invention provides a tooth segmentation method and device based on CBCT and electronic equipment, and the method comprises the steps: obtaining an oral cavity CBCT image, and determining a tooth region image in the oral cavity CBCT image; inputting the tooth region image to a pre-trained semantic segmentation network, and dividing the tooth region image into an upper tooth image and a lower tooth image; determining tooth surface data corresponding to each tooth in the upper tooth image and the lower tooth image; and inputting the tooth surface data into a pre-trained instance segmentation network, and segmenting a single tooth model corresponding to each tooth in the upper tooth image and the lower tooth image. The accuracy of segmenting the three-dimensional structure information of the single tooth from the CBCT image can be improved, and the segmentation effect is good. 本公开提供了一种基于CBCT的牙齿分割方法、装置及电子设备，通过获取口腔CBCT图像，确定所述口腔CBCT图像中的牙齿区域图像；输入所述牙齿区域图像至预先训练好的语义分割网络，将所述牙齿区域图像划分为上牙图像和下牙图像；确定所述上牙图像和所述下牙图像中，每颗牙齿对应的
