Abstract

The invention discloses a detection method of X-ray, comprising the following steps that: (1) the transmission image and the backscatter image of the subject detected are sampled in synchronous; (2) coordinate correction and matching of the transmission image and the backscatter image are performed to form the composite image showing the transmission information and the backscatter information of the subject detected; (3) the area and the area characteristics of the dangerous subject of the backscatter image are extracted; (4) the area of the corresponding dangerous subject in the transmission image is matched; and (5) the corresponding matched area in the composite image is marked and displayed. The method can realize the integration of the transmission image and the backscatter image, further enrich the image information of security check, and enhance the observation and identification efficiency of the security checker.

Description

technical field [0001] The invention relates to an X-ray detection method, in particular to a multi-detection detection method with X-ray fluoroscopy technology and backscattering technology, and belongs to the technical field of safety detection. Background technique [0002] At present, with the development of X-ray safety detection technology, it has become more and more common to have multiple detection technologies or multiple detection angles on one security inspection machine, so that multiple detection methods or multiple detections can be provided for the detected object. perspective, so as to provide security inspectors with richer and more comprehensive detection information, and improve the detection efficiency and accuracy of security inspectors. [0003] However, with the application of multi-detection technology and multi-detection angle of view, security inspectors need to observe the images of multiple displays at the same time for comparison, which undoubte...
