| Abstract: | Starting from a rigorous geometric model of ZY-3 satellite images, a look-angle calibration method for on-orbit geometric calibration of ZY-3 satellite imaging sensors was proposed by analyzing CCD look angles in a star sensor coordinate system. Two sets of ZY-3 satellite images covering Songshan area and Luoyang area were used, respectively. The empirical results have shown that the proposed method is simple and practicable and the calibration parameters have no correlation. The object positioning accuracy of nadir images is better than ±2.7 m and the planimetric and height accuracies of forward-backward stereo pairs are better than ±4.8 m and ±3.2 m respectively, after calibrating satellite sensor according to the proposed method without laboratory calibration parameters and with only five ground control points. Additionally, using CCD look angles obtained by the proposed method for extrapolative object positioning of ZY-3 satellite images, the object positioning accuracy of nadir images is better than ±11 m and the planimetric and height accuracies of object positioning of forward-backward stereo pairs are better than ±19 m and ±4 m respectively. |
