摘要
针对太阳影子的定位,综合分析直杆影子长度及坐标与所处地理位置、太阳直射点、时间的理化关系,建立了影子变化的动态模型和非线性方程拟合模型,运用MATLAB、MATHEMATICA软件求解,得出了直杆的太阳影子长度变化曲线图、直杆所处地理位置和监控视频的拍摄日期等结果。
The aim of the study on positioning of sun＇s shadow, we analyses the quantitative relationship between straight rod lengths, coordinate, geographical location, sunlit point of the sun and time comprehensively. And we set up the dynamic model of shadow changes and fitting model of nonlinear equation. By using MATLAB, MATHEMATICA software to solve, we draw the graph of the variation of sun shadow length, geographical location of the straight rod and the shooting data of the surveillance video.
