Event Camera Point Cloud Feature Analysis and Shadow Removal for Road Traffic Sensing

Xiao Lu et al.

Summary: Event cameras have wide applications in traffic flow detection due to their accurate identification of moving targets and insensitivity to stationary targets. In this study, an event camera is used in a roadside scenario to collect point cloud data, and a method for traffic target identification and shadow removal based on feature analysis is proposed. Experimental results show significant differences among different traffic targets, with the proposed method achieving a high accuracy of 96.5%.

PCT: Point cloud transformer

Meng-Hao Guo et al.

Summary: This paper introduces a novel framework named Point Cloud Transformer (PCT) for point cloud learning, based on Transformer and enhanced by farthest point sampling and nearest neighbor search for better capturing local context. Extensive experiments demonstrate that the PCT achieves state-of-the-art performance on shape classification, part segmentation, semantic segmentation, and normal estimation tasks.
