摘要

讨论一种基于RS和GIS的有别于一般和传统方法的地物BRDF构建原理。其核心是卫片像元坡面方向反射几何参数的逐点计算和地物不同坡面方向反射因子的反演计算。它开拓了一种在自然状况下能适应各种分辩率遥感卫星的不受地面测试仪器性能限制的快速、实时、自动地同时构建多种地物BRDF的新途径。

Abstract

A BRDF structure based on RS and GIS principle is discussed

and this principle differs from the traditional way. The kernel of the principle is inversion calculation of the reflectivity of the objects in different slope directions and one by one calculation of the reflection geometry parameters of the pixel slope directions. This principle extends a new approach with quick

real time and automatic way in natural environment for constructing a few objects' BRDF at the same time

which can be applied to remote sensing satellites of different resolutions without being restricted by the performance of analysis devices on the ground.
