摘要
基于光的直线传播特性,提出一种用多面体不同面上的传感器来测量光源空间角度的方法.通过建立等效矢量模型,将光源空间角度的测量变换为空间几何模型中几何角度的计算,降低了测量的复杂度,测量范围包括光源与检测点间的方位角和俯仰角,解决了现有技术测量范围不全的问题,适合在空中或地面对光源空间角度的测量.通过对太阳角度的实测分析,验证了方法的正确性和可行性.
A method of measuring light source angles is presented based on the optical line transmission characteristic.The sensors on the polyhedron flats to measure light source angles are applied.The light source angles measuring is changed into the geometry angles computing in the space geometry by means of constructing equivalent vector model,so that the measurement is simplified.The azimuth and the pitching angle between light source and the measured point are included in the measuring method.At the same time,this method is suitable for light source angles measurement in the sky or on the ground.In this way,the prior art measurement range insufficient is resolved.The results of the measurement for solar angle prove that the method is correct and feasible.
