Embodiment Construction
[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0037] Such as figure 1 As shown, the mosaic method of the three-line array image and the multi-spectral image of the No. 3 satellite of the present invention specifically includes the following steps:
[0038] 1) Establish a rigorous imaging geometric model of the real CCD line array;
[0039] ① Use the principal point of the panchromatic or multispectral camera (x 0 ,y 0 ), like the main distance f, the size of the pixel (x, y), and determine the coordinates of the pixel (x, y) in the panchromatic or multispectral camera coordinate system as:
[0040] x - x 0 y - y 0 ...
