摘要
考虑了实际物体表面BRDF的影响, 利用方向半球反射率、方向半球透射率、法向反射率和法向透射率等光谱数据, 同时反演了一维平板内介质和表面的辐射特性参数。将该方法用于吸收散射、强散射和强吸收三种介质的辐射特性参数反演, 反演结果与给定初值较吻合。
Abstract
The effect of the physical object BRDF surface is considered, and the radiative characteristic parameters of the internal medium and surface for a one-dimensional slab are inversed simultaneously by utilizing the spectral data such as directional hemisphere reflectivity, directional hemisphere transmissivity, normal reflectivity and normal transmissivity. The method can be applied to the inversion of radiative characteristic parameters of these three kinds of medium, such as the absorbing and scattering medium, the highly absorbing medium and the highly scattering medium, and the inversion result coincides well with its given initial value.
