摘要：

In the process of applying the theoretic results of BRDF model study to remote sensing image data, an important step is to extract BRDF features from multi-angular images. Because of the limitations of registration, pixel alignment and the intrinsic scale of scene, it is necessary to perform spatial average to the georeferenced multi-angular images before extracting BRDF feature. Otherwise the feature will not be representative to the surface property. Based on analysis of geometrical limitations, this paper discussed how the apparent BRDF feature changes from random to order after the spatial average.
