1. A method for processing intraoral scanning, comprising:
obtaining a positioning mode of a scan post in response to a request for scanning an oral cavity comprising scan posts;
scanning the oral cavity to obtain target scanning data; and
performing processing based on the positioning mode of the scan post and the target scanning data to determine positioning information of the scan posts;
wherein the performing processing based on the positioning mode of the scan post and the target scanning data to determine positioning information of the scan posts comprises: extracting auxiliary feature point information of texture images in the positioning mode of the scan post; performing three-dimensional reconstruction based on the auxiliary feature point information to obtain three-dimensional data of auxiliary feature points; and determining a scan post three-dimensional model based on the three-dimensional data of the auxiliary feature points, and determining the positioning information of the scan posts based on the scan post three-dimensional model.
