Interactive Visual Simulation of Satellite-borne Lidar Echo Scenes

Satellite-borne Lidar is widely used for both atmospheric observation and terrestrial scene observation. However, in the existing Satellite-borne Lidar simulation system, it is hard for the users to simulate the Satellite-borne Lidar over different photorealistic scene interactively. In this paper, we implement a simulation system of Satellite-borne Lidar echo with realistic scenes: First, a theoretical model is constructed based on the principle of Satellite-borne Lidar. Then, a set of realistic urban scenes as well as a serial of field scenes are built and the waveform simulation of Satellite-borne Lidar over the photorealistic scene is implemented. Thirdly the relevant parameters of the forestall scene together with the urban scene is inverted from the waveform acquired from the Satellite-borne Lidar. Also, a photorealistic scene of a specific area is built and the comparison between our simulation result and the echo of Satellite-borne Lidar in such area is taken. The experiment confirms the accuracy of our system on simulation of Satellite-borne Lidar echo scenes. Our system provides an efficient and convenient approach to the design and the application of Satellite-borne Lidar.
