太阳影子定位研究

Research on the Sun Shadow Positioning

针对太阳影子定位问题,使用最小二乘法、多项式联立、残差分析等方法,分别构建非线性回归、求解纬度等模型,应用MATLAB软件完成了太阳影子定位经纬度的公式推导与求解,并结合实际数据进行实践。此方法简便直观,实用性较强,可应用于破案侦查等现实案例中。

To solve the problem of suns shadow positioning, using the least square method and polynomial simultaneous, we build nonlinear regression model and the solving latitude model.With the help of MATLAB, we derive the sun＆#39;s shadow latitude and longitude of the formula, obtain the solution, and combine with the actual data in practice.This method is simple and intui-tive, practical, and can be applied to solve crimes in real case investigation , etc.
