摘要：

How to determine the location of the video is the important aspect of video data analysis and date taken, the sun's shadow positioning technology is based on analysising the sun's shadow change to determine the video shooting place and the date of video shooting. Firs, through the literature to get the expression of the length of the shadow, we find the longitude, latitude and date/time impact Angle of the sun, and then affect the length of the shadow. When we analysis the length of the shadow change rules of each parameter, we adopt the control variable method, and find that the length of the shadow basically don't change a lot with the growth of the year, with the increase of month and longitude, the length of the shadow gets shorter first, then gets longer, but with the increase of latitude the length of the shadow just gets longer. According to the expression of the length of the shadow We can get the curve of the impact of different parameters on the length of the shadow.
