Zusammenfassung:The invention discloses a parameter correction method for electronic anti-shake of a gyroscope, which is characterized in that a weight matrix K is obtained by combining rotation angles and translation amounts of X, Y and Z axes of a camera image sensor acquired by the gyroscope and rotation angles, transverse translation amounts and longitudinal translation amounts of a calibration image obtained by calculation; the electronic anti-shake parameter correction of the gyroscope is completed; and obtaining an affine matrix P on the basis of the weight matrix K, and performing inverse affine transformation on the original image of the jittering video through the affine transformation matrix P to obtain an anti-jittering image. According to the correction method, the influence of different camera internal parameters on the anti-shake effect is eliminated, the accuracy of the affine transformation matrix P is effectively improved, and the electronic anti-shake effect of the gyroscope is improved; the video jitter o
