RESEARCH ON THE PICTURE COLLECTED BY MICROMINIATURE AIRCRAFT TO CONSTRUCT DIGITAL ELEVATION MODEL

摘要

It is the primary step of the "digital city" that construct tridimensional digital map. We consider that construct it by computer vision base on the characteristic of the image microminiature aircraft collected. 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.
