Offline Extrinsic-Calibration-Free Cone-Based ROI Filtering for Lightweight Distributed Multi-Sensor Fusion on Edge Systems
We propose a lightweight cone-based Region of Interest (ROI) filtering method for camera–LiDAR fusion on distributed edge systems. Multiple Neural Processing Unit (NPU) nodes perform camera inference, and a central edge board combines their detections with LiDAR point clouds. The relative rotation is obtained from IMU...
