Dental operation equipment positioning method based on image recognition and system and storage medium

Abstract

The invention discloses a dental operation equipment positioning method based on image recognition and a system thereof, and the method comprises the steps: obtaining tooth image information of a target object, and carrying out the preprocessing of the image information based on a gray image; establishing a camera model, performing visual transformation according to the camera model, and projecting three-dimensional space points to a two-dimensional plane; judging whether target teeth are diseased teeth or not according to the tooth image information; establishing a tooth shape model, and determining the pixel coordinate information of the central point of the lesion area by solving the parameter information of the tooth shape model and the tooth image information; determining the coordinate information of the initial position of the dental operation according to the pixel coordinate information of the central point of the lesion area; and sending the position coordinate information to dental operation equipment, and grinding pathological tissues through a dental operation built-in dental drill.

Description

technical field [0001] The present invention relates to a positioning method for dental operation equipment, and more specifically, to an image recognition-based positioning method, system and readable storage medium for dental operation equipment. Background technique [0002] With the improvement of living standards, people have paid more and more attention to oral problems. Among oral diseases, the incidence of dental caries is relatively high. The number of cases of tooth repair, filling, and tooth replacement has increased significantly, resulting in a significant shortage of medical staff. In traditional dental operations, the filling of caries often requires doctors to use dental drills to grind away decayed tooth tissue, and because traditional caries There is no adhesion between the cavity filling material and the tooth tissue. It is necessary to use a dental drill to prepare a cavity of a certain shape according to the design for filling, and a part of the normal t...
