Abstract:
Semantic segmentation methods based on three-dimensional (3D) point clouds are mostly limited to input point clouds that have been divided into blocks for training. This is mainly attributed to the requirement of constant trade-offs between computational resources and accuracy for directly processing large-scale point clouds. Specifically, the block dividing strategy will add the data preprocessing time to some extent and may disturb the complete geometry of the object. Therefore, this paper proposes a large-scale point cloud semantic segmentation network without block dividing operation, referred to as ResDLPS-Net. This network can take the complete point cloud of the whole large scene as input and process up to nearly a million points on one single GPU. In particular, a novel feature extraction module is designed to efficiently extract neighbor, geometric, and semantic features. The learned features are then aggregated through the attention mechanism to form local feature descriptors. In addition, the proposed ResDLPS-Net is jointly trained by residual connections and dense convolutional connections to optimize the feature aggregation operation. As a result, the ResDLPS-Net performs brilliantly on multiple objects, such as windows, road markings, fences, etc.
