Environmental perception is widely recognized as the crucial part of intelligent transportation systems, in which point cloud semantic segmentation is an important task. High-performance semantic segmentation can help the system better understand the 3D world. This paper proposes a strategy of stacking base networks to construct high-performance segmentation networks. To reduce the model size and computational resource consumption, a novel lightweight method is proposed for compressing high-performance stacked point cloud segmentation networks. The proposed framework, called Stacked and Distillation Network Framework (SDNF), involves transferring the dark knowledge of the teacher network to the student network through the point cloud's structural information, attention information, and predicted labels. Finally, experiments with S3DIS dataset show that the proposed SDNF significantly improves the segmentation performance of both CNN/MLP-based and Transformer-based networks while keeping the model size minimal.
