摘要
本文主要研究太阳影子定位技术,以太阳高度角为切入点,借助天文三角形知识,探究太阳高度角、太阳方位角、太阳时角、太阳赤纬与经纬度、日期、地方时的关系,结合曲线拟合、联立方程式的方法,建立太阳影子定位的优化模型,运用MATLAB、EXCEL软件研究出太阳影子的变化规律、基于影子顶点坐标条件下物体的定时、定位,并将研究结果推广到视频数据分析领域对视频进行定位、定时.
The thesis majors in the positioning of sun＇s shadow,in our study,solar height angle is breakthrough,by means of the knowledge of the astronomical triangle,we analysed the quantitative relationship between sun elevation angle,solar azimuth,solar hour,solar declination angle and longitude,latitude,date,local time.Combining with the method of curve fitting and simultaneous equations,we set up the sun＇s shadow positioning optimizing model.By using MATLAB and EXCEL software,we worked out the laws for the change of sun＇s shadow,and ascertained the location and date.Finally we promoted our research result to the field of video data analysis.
