Wanli Zhong b06544bd54 Merge pull request #21918 from No-Plane-Cannot-Be-Detected:5.x-region_growing_3d ... Add normal estimation and region growing algorithm for point cloud * Add normal estimation and region growing algorithm for point cloud * 1.Modified documentation for normal estimation;2.Converted curvature in region growing to absolute values;3.Changed the data type of threshold from float to double;4.Fixed some bugs; * Finished documentation * Add tests for normal estimation. Test the normal and curvature of each point in the plane and sphere of the point cloud. * Fix some warnings caused by to small numbers in test * Change the test to calculate the average difference instead of comparing each normal and curvature * Fixed the bugs found by testing * Redesigned the interface and fixed problems: 1. Make the interface compatible with radius search. 2. Make region growing optionally sortable on results. 3. Modified the region growing interface. 4. Format reference. 5. Removed sphere test. * Fix warnings * Remove flann dependency * Move the flann dependency to the corresponding test		2022-05-23 14:47:57 +00:00
