Abstract: An improved dynamic template matching algorithm is proposed, which uses affine invariant moment as the invariable characteristic, when it recognizes goal. It uses one kind of improved canny algorithm to carry on edge detection to the goal, and removes false edge, and replaces the square shape template by using the rectangular template. This algorithm can improve real time. Experimental results indicate that, compared with traditional dynamic template matching algorithm, this algorithm has higher recognition rate and can down the computing quantity.

Key words: dynamic template, affine invariant moment, invariable characteristic, edge detection
