This paper presents a photogrammetric analysis of the solar aureole for the purpose of making photographic sky radiance measurements for determining aerosol physical characteristics. A photograph is essentially a projection of a 3-D object space onto a 2-D image space. Photogrammetry deals with relations that exist between the object and the image spaces. The main problem of photogrammetry is the reconstruction of configurations in the object space by means of the image space data. It is shown that the almucantar projects onto the photographic plane as a conic section and the sun vertical as a straight line.
本文介绍了一种对日晕进行摄影测量分析的方法，目的是通过拍摄天空辐射来测定气溶胶的物理特性。照片本质上是三维物体空间到二维图像空间的投影。摄影测量学研究的是物体空间和图像空间之间存在的关系。摄影测量学的主要问题是借助图像空间数据重建物体空间中的构型。结果表明，等高圈在摄影平面上投影为圆锥曲线，太阳天顶线投影为直线。
