Automatic epipolar image generation with ZY-3 TLS imagery

The methods of generating the epipolar image with ZY-3 TLS (Three Line Scanner) imagery are introduced in this paper. The proposed algorithms are employed by the ZY-3 Satellite Ground Data Handling System (GDHS) in China Centre for Resources Satellite Data and Application (CRESDA). The characteristic of ZY-3 TLS imagery and the principle of epipolar image generation with linear array CCD image are firstly introduced and the specific work flow aimed at ZY-3 TLS image is presented, then the practical applications of this epipolar image generation method in ZY-3 satellite GDHS are discussed. The satisfying experimental results with the developed system verify the efficiency and reliability of the proposed algorithms
