A method of point cloud data processing includes determining a 3D region of a point cloud data and a 2D region of a point cloud track patch frame onto which one or more points of the point cloud data are projected; and reconstructing, based on patch frame data of the a point cloud ...

A point cloud is a collection of data points in 3D space, where each point represents the X-, Y-, and Z-coordinates of a location on a real-world object’s surface, and the points collectively map the entire surface. Point clouds are commonly produced bylidar scanners, stereo cameras, a...

Point Cloud Datasets This repository provides ShapeNetCore.v2, ShapeNetPart, ModelNet40 and ModelNet10 datasets in HDF5 format. For each shape in these datasets, we use farthest point sampling algorithm to uniformly sample 2,048 points from shape surface. All points are then centered and scaled....
