The invention relates to an interactive object updating method and device, and a processing system, belonging to the technical field of image processing. The invention aims to solve the problems of local segmentation errors and the like in an existing segmentation method. The method comprises the following steps: retrieving a reference image and a segmented image corresponding to the reference image, wherein the reference image is a CBCT image; extracting unqualified sub-objects from the segmented image, wherein the unqualified sub-objects comprise sub-object slices of the segmented image and correct sub-objects with inconsistent tooth directions in the reference image; carrying out secondary segmentation and / or merging operation on the unqualified sub-objects, and updating the unqualified sub-objects into qualified sub-objects; and integrating the updated qualified sub-objects and the remaining qualified sub-objects in the segmented image into a re-segmented image, and updating the number of each sub-object in the re-segmented image, wherein different teeth in the updated re-segmented image have different numbers. According to the invention, a segmentation speed and segmentation accuracy are greatly improved through local segmentation and / or merging operation.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an interactive object updating method, device and processing system. Background technique [0002] Dental cone beam computed tomography (CBCT) is a diagnostic imaging technique that is widely used in the study of dental diseases and problems. Segmentation of a single tooth in a CBCT image helps dentists visualize slices or volumes of target teeth, enabling more precise diagnostic decisions and treatment planning. In addition, individual tooth segmentation is a necessary step in forming digital tooth arrangements, simulating tooth movement, and establishing tooth settings. However, manually segmenting teeth is tedious, time-consuming and prone to intra- and inter-observer variability. A method for automatically segmenting individual teeth can eliminate subjective errors in tooth boundary delineation and reduce the workload of dentists. [0003] With the develop...
