A Real‐Time and Fast LiDAR–IMU–GNSS SLAM System with Point Cloud Semantic Graph Descriptor Loop‐Closure Detection

Simultaneous Localization and Mapping In article number 2300138, Jieyu Wang and co-workers propose a simultaneous localization and mapping (SLAM) system. This design shows a picture of 'Hunyi', a Chinese ancient sensor, with Tai Chi Pisces, which are coupled and close-loop, and imply the loop closure detection process and the tight-coupled characteristics of the proposed SLAM system.
