Extrinsic calibration of heterogeneous cameras by line images [PDF]

open access: yesMachine Vision and Applications, 2014
The extrinsic calibration refers to determining the relative pose of cameras. Most of the approaches for cameras with non-overlapping fields of view (FOV) are based on mirror reflection, object tracking or rigidity constraint of stereo systems whereas cameras with overlapping FOV can be calibrated using structure from motion solutions.

An Extrinsic Calibration Tool for Radar, Camera and Lidar

open access: yes2019 International Conference on Robotics and Automation (ICRA), 2019
We present a novel open-source tool for extrinsic calibration of radar, camera and lidar. Unlike currently available offerings, our tool facilitates joint extrinsic calibration of all three sensing modalities on multiple measurements. Furthermore, our calibration target design extends existing work to obtain simultaneous measurements for all these ...
