The sun's shadow positioning technology is a method of determining the video filming location, through the analysis of object's shadow change in the video. After consulting relevant literature, we get the mathematical model for positioning by using the shadow of object, and predict the location in the example. Firstly, we establish the function of shadow's length and the relevant variable. We get the mathematical model about the parameters by the formula derivation. Secondly, by dealing with the data, we get the sun's shadow length of straight rod (once every 3 min test).Using the shadow length data after processing, we preliminarily determine the location of the longitude. Finally, using the shadow length change model, through the loop iteration method, using the condition of fixed length, we calculate the variance of rod long to identify the probable place of measuring the length.
