太阳影子定位研究
Research on the Sun Shadow Positioning
摘要
Abstract
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'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.关键词
