The invention relates to a CT detection method of a CT detection device, and the detection device, and relates to the technical field of CT detection. The problem that once a belt is stopped, a security inspector needs to move a detected object entering a detection area out of a monitoring area to carry out security inspection again is solved. The detection method comprises the following steps: acquiring a first image and movement data of a conveyor belt, wherein the movement data comprises the movement speed and the movement time of the conveyor belt; determining that the conveyor belt stops moving according to an externally input stop instruction; detecting whether the first image is the same as a pre-stored background image or not, wherein the background image is an image corresponding to the conveyor belt when no detection object exists; when the first image is different from the background image, generating a moving instruction according to the first image, the moving data and the rewinding time; control
