Context-dependent scan matching for aided navigation By Jyh-Ching Juang, Shang-Lin Yu and Shun-Hung Chen Context-dependent scan matching for aided navigation — finding the rotation and translation that best align two consecutive scans — provides laser-ranging data that can be blended into a GNSS navigation system. A quality index based on analysis of intra-frame point clouds assesses the scan context, accounting for variations... read more
