Abstract

The embodiment of the invention provides a tooth image processing method and device based on color clustering and electronic equipment. The method comprises the following steps: carrying out clustering analysis on a tooth image to be analyzed by adopting a color clustering algorithm; aiming at each obtained clustering region, calculating an average distance between the positions of all pixel points in the clustering region and the central position of the tooth image to be analyzed; then determining an enamel region, a dentin region and an alveolar bone region based on a preset distance relationship, and determining the first coordinate of the normal alveolar ridge crest position based on the enamel region, the dentin region and the preset distance; determining the second coordinate of the actual alveolar ridge crest position and the third coordinate of the tooth root apex based on the dentin region and the alveolar bone region; and finally, based on the first coordinate, the second coordinate and the third coordinate, determining a tooth bone loss proportion corresponding to the to-be-analyzed tooth image. Therefore, a more accurate bone loss proportion can be obtained by accurately analyzing the tooth image.

Description

technical field

[0001] The invention relates to the technical field of image processing, in particular to a method, device and electronic equipment for processing tooth images based on color clustering. Background technique

[0002] At present, image processing technology has been widely used in the field of medical technology to provide diagnosis basis for medical treatment. For example, a dentist can determine the proportion of bone loss in the tooth image by observing the tooth image, and then classify and stage the periodontal disease.

[0003] However, the inventors have found that the current way in which doctors observe dental images based on experience and obtain the bone loss ratio of dental images depends entirely on the doctor's experience. Therefore, the bone loss ratio obtained in this way is not very accurate, which will affect the accuracy of periodontitis grading and staging. Contents of the invention
