| Abstract: | The conception of BRDF(bidirectional reflectance distribution function) and some important vegetation indexes, NDVI(normalized difference vegetation index), EVI(enhanced vegetation index) and DVI (difference vegetation index) are introduced. The newly developed construct methods of vegetation BRDF models such as statistical inversion method , MODIS (moderate resolution imaging spectroradiometer) vegetation composition algorithm and EnKF(ensemble Kalman filter) are applied. The methods obtaining the BRDF data of object surface and improved Kernel-driven arithmetic are analyzed. The developing tendency of BRDF models is presented. |
| Keywords: | biological optics BRDF vegetation index NDVI |
