通过大量实验数据处理分析，给出了不同灰阶参考板的双向反射比因子随角度变化的特性，并阐明了参考板在野外太阳入射角不断变化条件下使用，双向反射比的校正显得非常必要。
Through a large number of experimental data processing and analysis, the bi-directional reflectance factors of different grayscale reference boards with angle variation are given, and the correction of the bi-directional reflectance is very necessary when the reference board is used under the condition of the changing solar incident angle in the field .
