基于数学模型的太阳影子定位问题研究

Research into the Sun Shadow Location Based on Mathematical Model

针对太阳影子的定位问题,通过分析影响影子长度的各个参数,建立了影子变化的数学模型。同时,根据某固定直杆在水平地面上的太阳影子顶点坐标数据,通过建立数学模型确定了直杆所处的地点以及视频拍摄的时间。该模型在实际生活中有着极为广泛的应用,具有一定的实际意义。

Facing the problem of sun shadow location,the mathematical model of shadow change is established by analyzing the parameters affecting the length of the shadow.At the same time,according to the data of the solar shadow vertex coordinates of a fixed straight bar on the horizontal ground,the mathematical model is established to determine the location and the time of video shot.The model has wide applications in practical life,so it has a certain practical significance.
