Research on the Shearer Positioning Method Based on SINS and LiDAR with Velocity and Absolute Position Constraints

open access: yesRemote Sensing, 2021
Accurate positioning of the shearer with a strapdown inertial navigation system (SINS) is the key technology to realize the automation of the longwall face. Unfortunately, the existing positioning methods have a strong dependence on the attitude accuracy
