Abstract

Three key techniques in registration of CBERS-02B image are introduced in this paper. Including an improved image matching strategy aided by a voting algorithm, the voting algorithm directly estimates the transformation parameters of image instead of finding the one to one corresponding, making the image matching much more efficient and reliable. Beside that, the method of handling the interior deformation problem caused by the incorrect splicing of three sub CCD arrays is introduced. At last, a virtual combination of satellite image technique is introduced, the adjacent satellite images in the same orbit are virtually combined to form a large image which is taken as the orientation unit, purposed on accelerating the orientation process speed and decreasing the probability of orientation failure. With the techniques mentioned above, the two main problems about CBERS-02B image: the inaccurate ephemeris parameters and the poor internal accuracy caused by the incorrect splicing of three sub CCD arrays are solved successfully, the absolute positioning accuracy reaches 1:10000 mapping accuracy and the internal accuracy reaches sub-pixel after the orientation process. It indicates that extensive usage of Chinese high resolution satellite imagery may become possible and practical.
