Security inspection image-based dangerous article image injection method

Abstract

The invention provides a security inspection image-based dangerous article image injection method, and relates to the technical field of security check image processing. The method includes: carryingout image preprocessing on a pre-injected dangerous article image; obtaining a to-be-processed package X-ray image matrix through security inspection equipment; determining whether a package is present, and obtaining the position of the package contour in the matrix; judging whether a dangerous article image can be injected or not according to the sizes of vacancies in the package image, fusing the dangerous article image and the package image if the dangerous article image and the package image can be injected, normalizing the dangerous article image and the package image, generating a picture, and outputting the picture; and normalizing an original package image matrix if the dangerous article image and the package image cannot be injected, and outputting the picture. The method providedby the invention is a method for automatically detecting the injectable position and fusing the image of the dangerous article image in security inspection, and can perform dangerous article image injection on the real-time security check image in a short time, thereby improving the injection accuracy and efficiency, and having better usability and robustness.

Description

technical field [0001] The invention relates to the technical field of security inspection image processing, in particular to a method for injecting dangerous goods images based on security inspection images. Background technique [0002] As the most widely used security inspection equipment, X-ray security inspection machines are widely used in various important safe public places. However, it is far from enough to rely on security inspection machines to detect dangerous goods. The ability of security staff to identify dangerous goods is also an important part of improving the efficiency of security inspection equipment. [0003] However, there are very few images of packages that actually carry dangerous goods in the conventional security check process, and the recognition ability of security check staff needs a lot of image recognition training to be improved, so the dangerous goods image injection technology came into being. Dangerous Goods Image Injection (TIP) is a fu...

Problems solved by technology

The circumscribing rectangle used for the package in the traditional method cannot well replace the outer frame of the irregular shape package, and the direct binarization of the entire image is relatively time-consuming
