Research on indoor position algorithm based on image sequence

People's demand for location information increase sharply, and people begin the research on the technology of vision location. In order to achieve of the result of exact and quick positioning, describe indoor position algorithm on block match of image sequence. First,initialize the image sequence, and then define search area, compute the MAD, return the coordinates of image, transform the coordinates, at last, get the change of two images. Experimental results show that the mobile track by algorithm can represent the actual path approximately.
