Set-Membership Extrinsic Calibration of a 3D LiDAR and a Camera

To fuse information from a 3D Light Detection and Ranging (LiDAR) sensor and a camera, the extrinsic transformation between the sensor coordinate systems needs to be known. Therefore, an extrinsic calibration must be performed, which is usually based …

Timestamp Offset Calibration for an IMU-Camera System Under Interval Uncertainty

To properly fuse IMU and camera information for robotics applications, the relative timestamp offset between both sensors' data streams has to be considered. However, finding the exact timestamp offset is often impossible. Thus, it is necessary to …

Timestamp Offset Determination Between an Actuated Laser Scanner and its Corresponding Motor

Motor actuated 2D laser scanners are key sensors for many robotics applications that need wide ranging but low cost 3D data. There exist many approaches on how to build a 3D laser scanner using this technique, but they often lack proper …
