Automatic Multi-Sensor Extrinsic Calibration For Mobile Robots [PDF]
IEEE Robotics and Automation Letters, 2019 In order to fuse measurements from multiple sensors mounted on a mobile robot, it is needed to express them in a common reference system through their relative spatial transformations. In this paper, we present a method to estimate the full 6DoF extrinsic calibration parameters of multiple heterogeneous sensors (Lidars, Depth and RGB cameras) suitable ...
