Abstract
In this paper, the variation characteristics of straight-bar's shadow are determined through analyzing the movement of the straight-bar's shadow.And meanwhile a mathematical model is established according to the coordinates of the length of the straight-bar's shadow in certain place, time, latitude, longitude and the length of the straight-bar to study the sun shadow positioning technology.Providing the location of the straight-bar is unknown, a least square fitting of the shadow length is obtained to determine the latitude and longitude, and the video about the variation of the straight-bar's shadow is used to determine the location of the bar and the filming date.Supposing the date of the straight-bar's length is unknown, the characteristics of the sun and the variation of the shadow length can be transformed into a spatial graphic to find a solution.关键词
