摘要
主要研究通过物体影子长度随时间的变化确定物体所处的地点和日期。通过Matlab编程运用穷举法穷举最优经纬度等信息,进而查找相应的地点和日期。首先,建立影子长度关于杆长、经度、纬度、日期和时间的函数模型,并分析各参数变化引起影子长度改变的规律。其次,建立由影子顶点坐标数据和时间确定物体的地点及日期的模型。最后,建立由物体影子随时间变化的视频确定拍摄地点和日期的模型。
In this paper, it mainly studies through the object shadow length changes over time to determine the location and data. Through MATLAB programming with exhaustive method, exhaustively the optimal information such as latitude and longitude is enumerated, and then the appropriate location and data are found. Firstly, it establishes the shadow length function model of bar length, the longitude, latitude, date and time, and analyses the shadow length changing laws as the various parameters changing. Secondly, by the shadow vertex coordinate data and time it sets up the model to determine the location of the object and the date. Finally, by video object shadow changes over time it establishes the model to determine the location and date.
