Abstract
Embodiments of the present disclosure disclose a single-tree segmentation method and apparatus. The method includes: acquiring point cloud data in a region to be segmented, classifying a highest point in the point cloud data into a target tree point cloud, setting an infinite point, and classifying the set point into a non-target tree point cloud; comparing similarity between a current point to be classified and a current target tree point cloud with similarity between the current point to be classified and a current non-target tree point cloud for each point to be classified in the point cloud data, and classifying the current point to be classified into corresponding point cloud according to a comparison result; and segmenting a final target tree point cloud into point cloud data corresponding to a target tree after all points to be classified are completely classified.
