摘要
太阳影子定位技术是通过分析物体的太阳影子变化,确定影子所在地点和日期的一种方法。通过建立影子长度变化模型,根据杆长与太阳影子长度的变化规律,研究太阳影子与当地经纬度的变化关系,采用MATLAB编程计算对物体进行有效定位。同时,根据时间变量与影子顶点坐标关系,利用太阳方位角的公式,求得直杆所处日期。
Positional calculation technology based on mines object＇ s shadow location and date by analyzing we systematically analyzed the bar length and change the sun shadow is the technology which deter- the changes of object＇ s shadow. In this article, rule of the sun＇s shadow length through the es- tablishment of the shadow length change model, and we studied the relation between the sun＇ s shadow and local latitude and longitude; We carried on the effective positioning to objects by MATLAB pro- gramming calculation. Meanwhile this measure can use the sun azimuth angle formula to obtain the date of rods according to the time variable relation and shadow vertex coordinates.
