1. A CT (Computerized Tomography) device based on motion compensation, comprising: a CT scanning device adapted to perform CT scanning on a scanned object; a stereo vision measurement system adapted to measure a motion parameter of the scanned object in synchronization with the scanning of the CT scanning device; and an imaging device adapted to compensate for the motion of the scanned object during the CT scanning by performing a transformation on a reconstructed image matrix based on the motion parameter.
