Abstract
With the continuous development of 3D data acquisition technology in recent years, it is more and more convenient to obtain the point cloud data of large scenes, which contains a variety of rich information. How to effectively and accurately classify and segment point cloud data of large scenes has become a research hot-spot in the field of computer vision. In this paper, we study the method based on clustering, make full use of the spatial location and context information, and propose a new network framework, FeatureB2SENet. In the 2D and 3D projection feature calculation, we generate a \(32\times 32\times 1\) feature image for each point and input it into the convolution neural network to process the feature image. Finally, a comprehensive verification analysis is carried out on GML\(\_\)A, GML\(\_\)B and Vaihingen data sets, which proves that the classification effect is better.
