Abstract
Disclosed is a method for detecting movement speed uniformity of a scanned target in a line scanning imaging process. The method comprises a first step of acquiring a scan image of a rectangular correction plate ABCD, a second step of performing data processing on a scan image A′B′C′D′ and a third step of calculating a uniformity representation value S of the movement speed of the scanned target. The uniformity of the movement speed of the scanned target can be calculated quantitatively, and the method can be used for precisely correcting a line scanning imaging system, so that high-precision image information about the scanned target is obtained, and the method can be applied to high-precision computer vision detection of the scanned target.
