Abstract: The present disclosure discloses a vehicle-mounted type back scattering inspection system. The vehicle-mounted type back scattering inspection system includes a carriage and a back scattering imaging device, the scanning range of the back scattering imaging device is variable. As the scanning range of the back scattering imaging device of the present disclosure is variably set, the inspection range of the back scattering imaging device can be expanded.

Abstract: The present disclosure discloses a vehicle-mounted type back scattering inspection system. The back scattering imaging device has a vehicle-mounted working state and a ground working state, and in the vehicle-mounted working state, the back scattering imaging device performs inspection work in a carriage; in the ground working state, the back scattering imaging device performs the inspection work on the ground at the outside of the carriage; and the back scattering imaging device is separately arranged relative to the carriage and is movable between the carriage and the ground to switch between the vehicle-mounted working state and the ground working state.

Abstract: The present disclosure provides a method and device for correcting a scanned image, and an image scanning system, and relates to the field of image scanning. The method includes obtaining a scanned image of a scanned object, detecting one or more reference objects from the scanned image, determining a deformation parameter of each reference object of the one or more reference objects based on preset a standard parameter of the each reference object, and correcting the scanned image based on the deformation parameters of the one or more reference objects.
