Image internal geometric error correction method and device based on yaw imaging

The invention provides an image internal geometric error correction method and device based on yaw imaging, and the method comprises the steps: obtaining a remote sensing image after a satellite platform carries out 90-degree maneuvering at a yaw angle; detecting straight lines in the image through a straight line detection method, and obtaining pixel coordinates of a starting point and an ending point of each straight line; all straight lines in the yaw image obtained by each detector are detected in the yaw image, coordinates of a starting point and an ending point of each straight line are obtained, and the angle of each straight line is calculated through the coordinates; fitting the angles of all straight lines of each detector to obtain an optimal straight line angle value beta of a yaw image of the detector, and obtaining an angle difference beta'between an actual position and a theoretical position of detector splicing; and according to the angle error of detector splicing, taking one detector as a re
