After pcl::VoxelGrid downsampling and filtering, the point cloud is explosive

Question introduction: slam builds the map, first reduces the line sampling, then carries on the visualization or the storage. However, after downsampling, the point cloud data is scattered into a mass without error. Show the code and point cloud data as follows, pcl::VoxelGrid<Lidar::PointType> voxel_filter; voxel_filter.setLeafSize ...

PCL: connect fields or data in two point clouds to form a new point cloud

1. Learn how to connect two different point clouds into A point cloud. Before operation, make sure that the fields in two data sets are of the same type and the same dimension. At the same time, learn how to connect the fields of two different point clouds (such as color normals). The mandatory constrai ...

Implementation of PCL_Superbody Clustering

1. Supervolume Clustering: A Segmentation Method from Image A supervoxel is a set whose elements are "bodies". Similar to the volume in voxel filters, they are essentially small squares. Unlike all the previous segmentation methods, the purpose of hypervolume clustering is not to segment a specific object. It implements over segm ...
