基于数学建模的太阳影子定位

Sun Shadow Positioning based on Mathematical Modelling

太阳影子定位技术对现代定位技术具有较为重要的参考价值,通过研究太阳下物体影子长度的变化情况与各个参数的关系,描绘动态变化规律曲线图.在此模型基础上,利用最小二乘法、曲线拟合的数学方法,根据物体影子的动态变化规律求出物体高度以及测量点所在地.

Sun shadow positioning technology is considered hugely important to modern positioning technology. By studying the relationship between shadow length’s change of an object under the sun and each parameter, the curve diagram of dynamic change law is drawn. On this basis, the height of the object and the location of the measuring point are found by using mathematical techniques including least square method and curve fitting, and combining the dynamic change law of the object’s shadow.
