Title:
IMAGE BOUNDARY ACQUISITION METHOD AND DEVICE BASED ON POINT CLOUD MAP AND AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2020/103110
Kind Code:
A1
Abstract:
Disclosed are an image boundary acquisition method and device based on point cloud map, an aircraft and a storage medium. The method comprises the following steps: obtaining a point cloud map containing semantics (S201); determining, according to the semantics on the point cloud map, respective image regions of different semantics on the point cloud map (S202). The described method can realize the automatic segmentation of image regions, satisfy the demands for automatic and intelligent classification of image regions, and improve the accuracy of image segmentation.
