Scanned image correction apparatus, method and mobile scanning device

A scanned image correction apparatus for a mobile scanning device, comprising an image collector, an arm swing detector, and an image processor, wherein:

• the image collector is disposed on a detector arm of the mobile scanning device and 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 the 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, wherein the arm swing model is used to fit a functional relationship between the displacement offset of the detector arm and time in the scanning process;
• and
• 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 based on the arm swing model and the image parameter of the scanned image, and correct the scanned image based on the change relationship.
