It is the primary step of the “digital city” that construct tridimensional digital map[ 1 ]. We consider that construct it by computer vision base on the characteristic of the image microminiature aircraft collected[ 2 ]. But the quantity of the pairs of the characteristic point cannot meet the request to construct Digital Elevation Model. This paper provide a latest correlate matching method base on Epipolar Constrain after introduce the characteristic point extract and matching. the paper adopt a precise Fundamental Matrix estimate algorithm to calculated epipolar equation and increase the matching point’s quantity effectively. It has met the real time’s request by experimental verification.
