The Urban Objects Classification Based on LiDAR 3D
The Lidar technology can quickly acquire three-dimensional information of earth surface with high precision.As a new technique of data collection acquisition,it has been gradually applied to many industry. The classification on point cloud is the premise and key step to the feature extraction and the model building of objects. Based on LiDAR 3D and ANN This paper presents a classification method mainly suitable for the urban’s typical objects. It takes the changsha city as the study area,to verify the effectiveness of this method.The result shows that,this classification method successfully classifies the categories of the ground,buildings,trees and bare lands.
