基于影子长度变化模型的视频定位研究

Research on Video Location Based on Shadow Length Change Model

针对确定视频的拍摄地点,综合分析太阳高度角、太阳赤纬角、影子长度等因素之间的相关关系,使用最小二乘法、多元统计分析等方法,分别构建了影子长度变化模型,经纬度确定模型等,运用EXCEL、MATLAB等软件编程求解,研究得出视频拍摄的可能地点是辽宁沈阳。

Aiming at the problem of determining the video location, we make a comprehensive analysis of the correlation between the solar elevation angle, solar declination angle, shadow length and other factors, using the least square method, multivariate statistical analysis and so on, then we construct the shadow length variation model, the latitude and longitude determination model by using EXCEL, MATLAB and other software programming solution. At last, we conclude the likely video location is in Shenyang, Liaoning.
