Abstract :
This paper presents a approach that uses 3D point clouds from laser sensor to perform the classification of typical obstacles in urban environments. The presented method consists of Velodyne Lidar point clouds segmentation, feature extraction and use of a MLP Neural Nets to classify vehicles, people, tree trunks, light poles and buildings. Experimental results demonstrated that is possible to recognize different classes of 3D structures with a very good precision. At the end, the performances of two neural networks are compared.
