A three-dimensional tooth model construction method, device, equipment and medium

Abstract

The present application relates to the technical field of dental digitization, and discloses a three-dimensional tooth model construction method, device, equipment and medium, comprising: acquiring multiple frames of oral stripe images and oral color images, performing stripe enhancement processing on the multiple frames of oral stripe images to obtain multiple frames of stripe enhancement images; extracting stripe center point coordinates and acquiring code values of the stripe enhancement images; performing mask region analysis on the oral color images and the code values by using a segmentation model to obtain a tooth region mask; obtaining target stripe center point coordinates and target code values through data screening; data encapsulating the target stripe center point coordinates, the target code values and the oral scene color images, and sending the oral encapsulated data to a cloud node; performing real-time point cloud reconstruction based on the oral encapsulated data to obtain three-dimensional point cloud data corresponding to the target user's teeth; and performing point cloud optimization on the three-dimensional point cloud data to obtain a three-dimensional tooth model of the target user. The present application can improve the efficiency of three-dimensional tooth model construction.
