Abstract

In this paper, the model of the solar shadow end plane coordinates and the measurement of the latitude and longitude, and the measuring time are established. The solution of the video shooting location and date is given by the change of the length of the shadow in the video. And the application of genetic algorithm based on BP neural network to the model error test and evaluation. If there were the date and time in the video, then the angle could be obtained, and the declination angle would be found directly by the relationship between the latitude angle and the dates with the known to rod length. Then because the ratio of is equal to the length of the rod and the shadow length, we can find out high noon sun angle and obtain the latitude and longitude after the fitting of the short film, corresponding to the calculated the noon solar altitude angle. When there was no date and time in the video, then according to the data of the solar shadow vertex coordinates of a fixed straight bar on the horizontal ground, the most suitable place and date of the straight rod is determined. This is an optimization problem, combined with global search and simulated annealing, two methods are listed to solve the objective function.
