4D-CS: Exploiting Cluster Prior for 4D Spatio-Temporal LiDAR Semantic
Segmentation
Semantic segmentation of LiDAR points has significant value for autonomous driving and mobile robot systems. Most approaches explore spatio-temporal information of multi-scan to identify the semantic classes and motion states for each point. However, these methods often overlook the segmentation consistency in space and time, which may result in point …
