摘　　要：太阳照射下物体的影子长度和角度的变化规律包含着物体所处位置和时间的信息,本文运用日晷原理,建立影长与太阳赤纬、地理纬度的表达式,进而构造基于物体影长的定位模型。最后进行了数值模拟,根据影长数据准确定位了物体所处的经纬度。The information of the position and time of the object can be inferred by the variation of its length and angle. In this paper, the principle of sundial is used to establish the expression of the geographical lati- tude of the shadow length and the declination of the sun. Furthermore, the location model based on the object length is constructed. Finally, the numerical simulation is carried out, and the longitude and latitude of the object are accurately located according to the shadow length data.
