HiPFuse: Real-Time LiDAR Semantic Segmentation for Robotic Perception on Edge Devices
Overview
This paper introduces HiPFuse, a point-BEV fusion framework designed for real-time LiDAR semantic segmentation on edge devices. The method exchanges point and height-partitioned BEV features across horizontal scales while preserving separate vertical aggregation groups through fixed height assignments. Evaluated on SemanticKITTI and MCD datasets, HiPFuse achieves 63.7% and 62.5% mIoU at 14.2 and 22.4 FPS respectively on Jetson AGX Orin, exceeding the 10 Hz scan rate. When integrated into fixed robotic systems, it reduces odometry absolute trajectory error RMSE by 10.6% on average across two outdoor sequences and increases accepted-loop recall by 8.7 percentage points on SemanticKITTI. The code is available at https://github.com/haiyang2022/HiPFuse.

“ining and evaluation show indoor applicability. Replacing only the baseline semantic front end with HiPFuse in fixed robotic systems reduces odometry absolute trajectory error RMSE by 10.6% on average across two outdoor sequences and increases accepted-loop recall by 8.7 percentage points on SemanticKITTI. Qualitative semantic maps show more continuous road labeling. Our code is available at https://github.com/haiyan”
