Embodiment Construction
[0048] The present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.
[0049] The present invention proposes a sensor correction method for steady-state re-imaging of high-resolution optical satellites, which uses a virtual single-line array CCD without distortion to replace the original distorted sliced CCD image, and converts the original non-steady state (integral jump, sliced difference, etc.) Speed, attitude jitter) push-broom imaging conditions into a stable, uniform (integral constant, slice at the same speed, attitude smooth) push-broom imaging conditions, re-imaging under steady-state conditions, so as to obtain a complete scene without distortion images, while obtaining high-precision RPCs for steady-state imaging.
[0050] During specific implementation, the technical scheme of the present invention can be realized by those skilled in the art using computer software technology to automatically run ...
