Abstract

The present application discloses a point cloud sampling method, device, equipment and computer-readable storage medium for obtaining point cloud data to be sampled, sampling the point cloud data to be sampled, and obtaining initial sampling data; based on the point cloud data to be sampled The cloud data adds sampling points to the initial sampling data to obtain target sampling data. Compared with the sampling algorithm with high algorithm complexity and huge amount of calculation in the prior art, this application obtains the initial sampling data by first sampling the point cloud data to be sampled, and then performs sampling point supplementation on the initial sampling data to obtain the target Sampling data can effectively reduce the computational complexity and the amount of calculation required for sampling, thereby improving the efficiency of point cloud sampling.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a point cloud sampling method, device, equipment and computer-readable storage medium. Background technique [0002] When performing point cloud sampling, due to the massive and disordered nature of point clouds, the processing method of direct sampling requires high computational cost when searching the neighborhood. A commonly used solution is to downsample the point cloud, and convert the operation of the entire point cloud to the points obtained by downsampling, thereby reducing the amount of calculation. The commonly used down-sampling method is the farthest point down-sampling method, and the farthest point sampling is a relatively simple uniform sampling method. The specific method is: the input point cloud is recorded as P, and the sampling point set is recorded as Q. Before sampling, the sampling point set Q is empty. In the first step, randomly c...
