- Abstract
Shadows of the sun position techniques can determine the place and date of the video. First, use Matlab to extract video files, extract n pictures at such intervals, after reading the picture get n sets of the shadow length l changes with time t. Known date from capture date calculate solar declination, using least-squares optimization model, each parameter the mathematical relationship was established, the longitude and latitude as an unknown parameter nonlinear fitting, fitting location for Inner Mongolia Erdos (110.52 ° East longitude, latitude 39.89 °); Unknown date, the question will be transformed into longitude and latitude, declination angle of nonlinear equations three unknowns, using genetic algorithms to find possible locations for Inner Mongolia Erdos (longitude 109.36, 40.16 ° North latitude), capture date is June 22.
