Web24 de abr. de 2015 · Limitations: This approach works well if your data comes from a volumetric dataset or if you have a cloud of points that can easily be converted into a volumetric data set (voxel-like). This can be done relatively easily with a dense set of points using, for example, a spatial indexer like the scipy cKDTree , but you might end up … Web19 de fev. de 2024 · I have a point cloud with PCL. I want to split the point cloud into many small surfaces each containing, let's say, 120 points. It's not about just making chunks of points from the cloud.

"WebThe PCL Registration API. The problem of consistently aligning various 3D point cloud data views into a complete model is known as registration. Its goal is to find the relative positions and orientations of the separately acquired views in a global coordinate framework, such that the intersecting areas between them overlap perfectly.
