CT detection method of CT detection device, and detection device

Abstract

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; controlling the conveyor belt to move through the moving instruction; acquiring a second image of the detected object; and splicing the first image and the second image to obtain a complete image of the detected object. According to the technical scheme provided by the invention, the security check efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of CT detection, in particular to a CT detection method and a detection device of a CT detection device. Background technique [0002] X-ray computed tomography imaging technology (abbreviated as "CT technology") is highly valued and widely used in the field of security inspection due to its own unique advantages. [0003] Most of the current security inspection CT equipment cannot be stopped during the package detection process. Once the belt is stopped, the security inspector needs to move the detection objects that have entered the detection area to outside the monitoring area and perform security inspection again, thereby reducing the efficiency of security inspection. Contents of the invention [0004] In view of the above analysis, the present invention aims to propose a CT detection method and a detection device of a CT detection device, so as to improve security inspection efficiency. [0005] The...
