选取9个水杉样地进行单木分割精度验证，以无人机影像点云单木分割探测到的

9 plots Metasequoia selected for segmentation of individual tree treetops authentication precision to single point cloud wood UAV image segmentation detected as the center, divided individual tree crown radius length, fitting the individual tree division point cloud images canopy, thereby verifying the accuracy of individual tree segmentation.

Select 9 water fir samples to carry out the single-wood division accuracy verification, with the uavouring image point cloud single-wood split detected tree top as the center of the circle, single-wood split tree crown length as a radius, fitting the image point cloud single-wood division of the tree crown, thus verifying the accuracy of single-wood segmentation.

Nine plots of Metasequoia are selected to verify the accuracy of single wood segmentation. The tree top detected by point cloud single wood segmentation of UAV image is taken as the center, and the length of tree crown segmented by single wood is taken as the radius to fit the tree crown segmented by image point cloud single wood, so as to verify the accuracy of single wood segmentation.<br>
