Abstract

Abstract:

A laser scattering scene model capable of the real-time rendering of the laser radar imaging is proposed. It is based on the basic theory of laser radar imaging, combining true performance of the surface characteristics. Using the framework and taking advantage of powerful parallel computing ability of the GPU(Graphic Processing Unit), the radiance distribution under different laser incident angles, viewing angles and locations is implemented. A simulated calculation of a laser scattering scene image under a typical 3D scene is conducted. A comparison of the calculated results with the real lidar image is made, which shows that the laser scattering scene image obtained by the laser scattering scene model is similar to the one received by the lidar system. Quantitative analysis shows that there also exists difference, with the reasons analyzed.

Key words: laser imaging radar, real-time rendering, bidirectional reflectance distribution function, high performance computing
