description The invention discloses an automatic registration method for panchromatic images and multispectral images of a Gaofen-7 satellite, which comprises the following steps of: S1, acquiring geometric imaging model parameters of the panchromatic images and the multispectral images in various wave bands, and constructing geometric imaging models of the panchromatic images and the multispectral images in various wave bands; S2, constructing a unified virtual CCD geometric imaging model of the panchromatic image and the multispectral image of each wave band by using geometric imaging model parameters of the panchromatic image and the multispectral image of each wave band; and S3, generating a strictly registered panchromatic image and a strictly registered multispectral image based on a unified virtual CCD geometric imaging model of the panchromatic image and the multispectral image of each wave band. The method has the advantages that the registration problem of the panchromatic image and the multispectral image of t
