Ruan 0cf0a5e9d4 Merge pull request #21095 from No-Plane-Cannot-Be-Detected:next_SIMD ... Accelerated 3D point cloud Farthest Point Sampling calculation using SIMD. * Add several 3D point cloud sampling functions: Random, VoxelGrid, FarthestPoint. * Made some code detail changes and exposed the random number generator parameters at the interface. * Add simple tests for sampling. * Modify interface output parameters. * Modify interface return value. * The sampling test is modified for the new changes of function interface. * Improved test of VoxelGridFilterSampling * Improved test of VoxelGridFilterSampling and FPS. * Add test for the dist_lower_limit arguments of FPS function. * Optimization function _getMatFromInputArray. * Optimize the code style and some details according to the suggestions. * Clear prefix cv: in the source code. * Change the initialization of Mat in the sampling test. * 1. Unified code style 2. Optimize randomSampling method * 1. Optimize code comments. 2. Remove unused local variables. * Rebuild the structure of the test, make the test case more reliable, and change the code style. * Update test_sampling.cpp Fix a warning. * Use SIMD to optimize the farthest point sampling. * Optimize the farthest point sampling SIMD code. * 1. remove `\n` from the ptcloud.hpp comment. 2. updated the default value of the argument arrangement_of_points in the _getMatFromInputArray function in ptcloud_utils.hpp from 0 to 1, since the latter is more commonly used (such arrangement is easier for SIMD acceleration). 3. removed two functions in ptcloud_utils.hpp that were not used. * Remove the <br> in the comment. * Fix whitespace issues.		2021-11-30 12:33:44 +00:00
