description The invention discloses an in-orbit geometric calibration method for a linear array sweep-type optical remote sensing satellite, and the method comprises the following steps: 1, obtaining a ground control point on a linear array sweep-type optical remote sensing satellite image from high-precision reference data through an image matching or manual measurement mode; 2, according to the imaging geometrical relationship of the linear array swing-scanning optical satellite, constructing an in-orbit geometric calibration model of the linear array swing-scanning optical satellite; and step 3, solving imaging geometric parameters of the linear array sweep optical satellite by using ground control points and adopting a step-by-step solving strategy. According to the method, accurate solving of the linear array swing-scanning type optical satellite imaging geometric parameters can be realized, so that support is provided for high-precision geometric processing of linear array swing-scanning type optical satellite imag
