In order to improve the fidelity of laser imaging simulation,the ray tracing method is used to construct a laser radar system which can get the synthetic laser radar images of 3D scenes.By using the laser scattering law,the illumination model widely used in computer graphic is modeled into a laser radar imaging model for high-fidelity simulation.The improvements of the model are follows: 1adding the direct reflection term, 2changing the multiple light source model in luminance into the multiple reflection m...
