Embodiment Construction
[0043] A remote sensing satellite multispectral image registration method, the specific steps are as follows figure 1 As shown, the method is implemented by the following steps:
[0044] 1. According to the distance between the blue, green, red, and near-infrared spectral detectors of the multispectral camera, the obtained four spectral images are respectively cropped to obtain a coarsely registered multispectral image.
[0045] For the multispectral camera, the spectroscopic prism is used to obtain multispectral images. There is no offset between the four spectral segments, and there is no need to crop the input four spectral segment images. The obtained four spectral segment images are coarsely registered. Multi-spectral image; for multi-spectral cameras, multi-color CCD detectors are integrated on one device to obtain multi-spectral images, such as Figure 2a As shown, the distances from the blue-band detector on the focal plane to the green, red and near-infrared detector...
