A New Pseudorigorous Lidar System Calibration Strategy with Minimal Requirements and Higher Capability

Most times, rigorous airborne Light Detection and Ranging (LiDAR) system calibration is not possible because the raw measurements are unavailable, and pseudorigorous approaches that synthesize the raw measurements from the point cloud (and in some cases the trajectory) are used. The Quasi-Rigorous/Quasi-Simplified is a new pseudorigorous approach proposed here which is more useful when compared to the existing pseudorigorous approaches (Simplified and Quasi-Rigorous) because it has the same minimal data requirements as the Simplified but provides the higher capabilities of the Quasi-Rigorous. The experimental results compare the Quasi-Rigorous/Quasi-Simplified approach to the existing pseudorigorous (Simplified and Quasi-Rigorous) and rigorous approaches. When compared to the existing approach with minimal requirements (the Simplified), the results show that the Quasi-Rigorous/Quasi-Simplified approach is equally successful in significantly reducing the impact of systematic errors and offers additional capabilities in that it can be used on any type of terrain, can use nonparallel flight lines, and can incorporate control.
