This invention provides a method and apparatus for 3D tooth reconstruction based on multi-view geometric priors and specular Gaussian representation. The method first acquires multi-view image data containing teeth and gingiva. A multi-view geometric estimation module predicts and globally aligns dense 3D point maps to obtain an initial point cloud, camera intrinsic and extrinsic parameters, and a depth map. Based on this, a Gaussian primitive set is initialized and input into a specular Gaussian reconstruction module, where relevant parameters are combined to optimize the reconstruction. This module introduces depth and normal losses based on the color target, supervises and reduces the weight of highlight regions within the region of interest, and finally outputs the 3D reconstruction result. This invention can improve the stability and geometric accuracy of tooth reconstruction under high reflectivity and weak texture, enhance specular reflection and highlight expression capabilities, and balance the detailed reconstruction of tooth hard tissue with the geometric and appearance effects of gingival soft tissue, thereby improving the integrity of oral scene reconstruction and its clinical application value.
