ACCURACY AND ERROR ASSESSMENT OF TERRESTRIAL, MOBILE AND AIRBORNE LIDAR

摘要

The purpose of this paper is to demonstrate the advantages of using multiple sensor platforms to improve the absolute accuracy of Airborne Laser System (ALS) and Mobile Laser System (MLS) data sets. Terrestrial Laser Scanners (TLS) are capable of superior point positioning accuracies compared to ALS or MLS Systems. In this research we utilized high precision - high resolution geo-referenced TLS scans as a platform to analyze and improve the positioning of geo-referenced ALS scan data. Our research demonstrated an improvement in both registration and statistical analysis of ALS data.
