Abstract

LiDAR is a potential technology in mapping field. Especially, the LiDAR systems applying streak tube have attracted great attention recently due to their special properties about detection sensitivity and distance resolution. The simulation of the stripe principle array LiDAR system with "broom" scanning and the results of the flight experiment were described. Firstly, the establishment of the new LiDAR simulation platform and the typical simulation results were introduced. The simulation platform can guide the design of the new LiDAR, and simulate the setting of the airborne flight experiment parameters. The simulation result which was based on experimental design parameters was that the distance measuring accuracy of the new LiDAR is 0.5 meters. Finally, the airborne flight experiment of the new LiDAR was carried out, then original streak images of the typical area and the cloud points of the images were given. The result of the airborne flight experiment is that the distance measuring accuracy of the new LiDAR is better than 1 m. The accuracy of airborne flight experiment is consistent with the result of simulation analysis. It proves that the correctness of the simulation system is verified. Compared with the images of the passive optical camera, the technical feasibility of the new LiDAR in aerial mapping is verified.
