One target to align them all: LiDAR, RGB and event cameras extrinsic calibration for Autonomous Driving
A novel multi-modal extrinsic calibration framework is presented that simultaneously aligns event cameras, LiDARs, and RGB cameras using a custom 3D calibration target. This single process estimates relative poses between all three sensors by detecting unique features on the target across different sensing modalities. The method achieves high accuracy, especially for event camera and LiDAR alignment.
