遥感与地理信息系统支持下的地物BRDF反演研究

Research of BRDF is a basic and important research in the realm of RS technology. The content and method of this project are as follow. As the sun's ray redistributes on rugged ground, the incidence angle of sun's ray and the reflection angle of satellite's direction are changing. The radialization parameter and reflecting geometrical parameter of pixels of satellite image are calculated using DTM. We can calculate the incidence illuminance and the reflection luminance using DTM，and establish corresponding database. We do the jobs of Statistic of the radicalization parameter and reflecting geometrical parameter which belong to the same class object to establish its BRDF. At last multi-class object's BRDF is established, and the research of BRDF inversion is accomplished. The project is original and advanced in the realm of analyzing digital RS image and establishing multi-class object's BRDF.
