Segmentation of building facade point clouds using RANSAC

LI Na①②,MA Yi-wei③,YANG Yang④,GAO Sheng-li③(①Institute of Remote Sensing Applications,Chinese Academy of Sciences,Beijing 100101,China;②Troops 96633,Beijing 100096,China;③Troops 61512,Beijing 100088,China;④Institute of Surveying and Mapping,Information Engineering University,Zhengzhou 450052,China)  
Segmentation of building facade point clouds is the foundation of feature extraction and modeling from Vehicle-Borne LiDAR.In the paper,Random Sampling Consensus was introduced into the segmentation of LiDAR and r-radius point density was put forward to the estimation criterion,which aims to remove the discrete point outside the feature plane.Then two constraints of angle and distance were erected to unite the segmented planes which optimized the results.
