Abstract  Now point cloud semantic segmentation is widely applied in various fields such as autonomous driving and virtual reality. However, the current point cloud semantic segmentation algorithms cannot extract relatively complete spatial structure information, and the information for each point is difficult to explain. To address this deficiency, a 3D point cloud semantic segmentation network based on coding feature learning is proposed. Firstly, the local feature encoder is designed based on the introduction of angle information and the enhanced features to learn more complete local spatial structures and alleviate the problem of misclassification of similar objects. Secondly, mixed pooling polymerization module is designed to aggregate rough features and fine features while ensuring the sorting invariance of point cloud. Finally, the multi-scale feature fusion is adopted to fully utilize the different scale features in the encoding layer and achieve accurate semantic segmentation. The experiment on two large benchmark datasets, S3DIS and SemanticKITTI, demonstrates the superiority of the proposed network.
