浅析太阳影长定位

Analysis of the Solar Shadow Length Positioning

本文建立了影子长度基于太阳高度角变化的数学模型,即为影长变化模型,在此基础上进行太阳影长的定位.将查阅得到的数据用MATLAB进行处理从而确定物体所在地的经度,再根据物体原长不变的原理,进一步确定了物体所在地的纬度,进而通过太阳影长确定了物体所在的地理位置.

It is established in this paper that the shadow length based on the mathematical model of the solar altitude angle, namely the shadow length change model, based on sun shadow long positioning. We consult the obtained data using MATLAB to determine the longitude of the location of the object, according to the principle of original object lengths are fixed, and further to identify the latitude of the location of the object, and through the sun shadow length to determine the objects in their geographical location.
