A tooth three-dimensional reconstruction method and device based on multi-view geometric prior and mirror Gaussian representation
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.

Slow-moving small target trajectory detection method based on multi-frame coloring in reverberation background
This invention proposes a slow, small target trajectory detection method based on multi-frame coloring in a reverberant background. It employs the GMM or RPCA method, and obtains a spliced tensor through direct or selective splicing. The spliced tensor is then colorized to obtain a colored trajectory detection result. This invention utilizes the inter-frame positional migration continuity of slow, small targets, the inter-frame positional randomness of dynamic reverberation, and the inter-frame positional invariance of static reverberation to detect continuous target trajectories. In the detection results, static and dynamic reverberation are colored with a single color, and the continuous target trajectory is represented by color gradient stripes. The basic principles and implementation scheme of this invention have been verified through synthetic data processing results. The results show that, compared with traditional methods, the proposed colored trajectory detection method fully utilizes the frame-domain differences between slow, small target trajectories and dynamic and static reverberation, resulting in better continuous trajectory detection performance.
