Image registration plays an important role in terrain-aided navigation system.Normalized cross correlation method(NCC)is a relatively good method with anti-noise ability and precise.It is widely used in the navigation system.Because the computing quantity is huge
it needs to be improved in order to satisfy the fastness of navigation.A method based on NCC and convolution is proposed.It becomes much more fast.Experimental results verify its efficiency and fastness.
