本文给出物体在太阳底下影子长度及影子方位角的动态变化规律,据此建立确定物体所处位置和日期的非线性最小二乘模型,讨论相应的求解方法。在此基础上,利用针孔成像原理,根据视频中物体影子的变化规律来确定视频的拍摄日期和地点。
Abstract：In this paper,dynamic variation principles of the shadow length and azimuth are presented.Thus,a nonlinear least squares model that determines the place and date of an object is established,and numerical methods are discussed.Finally,applying the pinhole imaging principle,a mathematical model for determining the date and place according to the video is given。
