Abstract
The present disclosure provides a scanned image correction apparatus, method and a mobile scanning device. The apparatus includes an image collector, an arm swing detector, and an image processor. The image collector is configured to collect a scanned image of an object under inspection during a scanning process of scanning the object under inspection by the mobile scanning device, and determine an image parameter of the scanned image. The arm swing detector is disposed at a monitor point on a detector arm of the mobile scanning device, and configured to detect a displacement offset of the detector arm in a specified direction and build an arm swing model of the detector arm. The image processor is configured to determine a change relationship between the image parameter of the scanned image and the displacement offset of the detector arm, and correct the scanned image based on the change relationship.
