Thanks so much for the reply. Surfaces of R3 are ubiquitous in science estimating the local differential properties of a surface discretized as a point cloud estimation consists of resorting to polynomial fitting, either interpolation or approximation, but this route. Something similar to pcregrigid would be ideal but that is a non-rigid transformation. I want to use MATLAB to convert point cloud into intensity image. Users must manually bring point cloud. My aim is to apply Point Cloud Library to the KITTI dataset to register the point cloud captured by Velodyne (that is make a 3d map using the collected KITTI Velodyne data). Computer Vision Toolbox provides algorithms, functions, and apps for designing and testing computer vision, 3D vision, and video processing systems. Wolfram Cloud Central infrastructure for Wolfram's cloud products & services. I have two sets of cloud points that I am trying to wrangle with, both of which have the shape of a part of an elliptic parabolid. For the comparison between the two point clouds the result of the ICP registration method was used. View Nishita Tanwar’s profile on LinkedIn, the world's largest professional community.
