Hello 算法 (hello-algo.com)

输入点云或低分辨率体素，提取特征后利用GAN网络，生成每个顶点的位置和SDF偏移值，得到优化后顶点的位置和SDF
结合显式与隐式表达的表示方法，利用MT，从隐式SDF中重建出显式mesh

pairwise registration models, only Ubuntu

Issue:
How should I train my dataset? · Issue #4 · WHU-USI3DV/SGHR (github.com)
I think several point clouds of a single statue is not enough for training deep descriptors. I suggest to directly use pairwise registration models such as Geotrainsformer pre-trained on object-level datasets such as ModelNet40 to solve the pairwise registrations.
And adopt SGHR’s transformation synchronization section to solve the global consistent scan poses.
