The Image-assisted Extraction of Geo-spatial Features from LiDAR Point Clouds
摘要
Abstract
Accurately capturing geo-spatial features from LiDAR Point clouds is a key work in the process of LiDAR data processing. In view of the deficiency of LiDAR point cloud data classification in filtering and accurate capturing geo-spatial features,this paper presents a method for image-assisted capturing of geo-spatial features from LiDAR point clouds. First,according to the elevation value of LiDAR point clouds, resample and generate the elevation projection image,and automatically segment it. In the meanwhile,capture the features from the high resolution DOM. Then,conduct integrated analysis of the images of the features and segmented images,and process the wrong,leakage,precise classification of the LiDAR point clouds using the result of image extraction. The feasibility and effectiveness of the method are verified with experiments.关键词
