Abstract

A method for calculating the ground position of a CCD image is applied in the technical field of remote sensing image processing, comprising: taking the sub-satellite point of the satellite used to shoot the CCD image as the origin, the meridian direction as the X axis, and the normal direction perpendicular to the earth's surface as Z axis, establish the three-dimensional rectangular coordinate system of the station center, calculate the coordinates of the ground point corresponding to the pixel point of the CCD image in the three-dimensional rectangular coordinate system of the station center, and convert the coordinates of the ground point in the three-dimensional rectangular coordinate system of the station center to the ground-fixed three-dimensional coordinate system at the center of the earth Coordinates in the coordinate system. The disclosure also provides a device for calculating the ground position of the CCD image, electronic equipment and a storage medium. The disclosure can solve the problem that the prior art cannot directly and explicitly solve the ground coordinates for the satellite-borne linear array CCD remote sensing image.

Description

technical field [0001] The present disclosure relates to the technical field of remote sensing image processing, and in particular to a method, device, electronic equipment and storage medium for calculating the ground position of a charge coupled device (CCD, Charge Coupled Device) image. Background technique [0002] The linear array CCD satellite remote sensing image is a two-dimensional image on the ground obtained by a push-broom method through the linear array CCD loaded on the satellite, which has the advantage of high resolution. In practical applications, especially in some special cases, it is necessary to obtain the ground position information of the target point of interest on the linear array CCD satellite remote sensing image in real time, which requires the satellite to have on-orbit real-time calculation of the ground position of the linear array CCD satellite remote sensing image Ability. [0003] The ground positioning model of linear array CCD satellite r...
