CoBigICP is a fast and accurate point cloud registration method, currently implemented in MATLAB.
Reconstruction results of ETH Hauptgebaude generated by CoBigICP and GICP. Both estimated aligned point clouds are colored, with the ground truth being white.
CoBigICP can solve 3D rigid transformation between two point clouds. It adopts correntropy as the noise model and prunes putative nearest neighbor by a bidirectional search step. Also a symmetric objective function is used to gather surface geometric information. For more information, please refer to our paper. (pdf)
Git clone or download the repo and add to your MATLAB workspace.
Run CoBigICP_fun.m to align two scans from ETH Hauptgebaude.
