Observability-Aware Online Multi-Lidar Extrinsic Calibration
Accurate and robust extrinsic calibration is necessary for deploying autonomous systems which need multiple sensors for perception. In this paper, we present a robust system for real-time extrinsic calibration of multiple lidars in vehicle base frame without the need for any fiducial markers or features.

Extrinsic Calibration of a Camera and a 2D LiDAR Using a Dummy Camera With IR Cut Filter Removed
Extrinsic calibration of a camera and a LiDAR is necessary to fuse information from each sensor. The real trajectory of the LiDAR is not visible on an image, therefore the accuracy of the extrinsic calibration is usually checked by evaluating residuals ...
