Gaussian mixture descriptor improves 3D fragment matching for object reconstruction

Researchers have introduced a new method called the Gaussian Mixture Descriptor (GMD) for matching 3D fragments in object reconstruction tasks. This descriptor utilizes Gaussian Mixture Models to analyze and describe the distribution of points on fractured surfaces, enabling more accurate identification of adjacent fragments. The approach involves segmenting local surface patches, estimating GMM parameters for concave and convex regions, and then merging these regional descriptors. Similarity between GMDs is measured using L2 distance, with fragment alignment facilitated by RANSAC and ICP algorithms. AI

    Gmd: Gaussian mixture descriptor for pair matching of 3D fragments

    In the automatic reassembly of fragments acquired using laser scanners to reconstruct objects, a crucial step is the matching of fractured surfaces. In this paper, we propose a novel local descriptor that uses the Gaussian Mixture Model (GMM) to fit the distribution of points, al…
