Problems solved by technology
The appearance of objects in security inspection images will be affected by external factors such as object overlapping and occlusion, and due to differences in imaging principles of X-ray security inspection equipment and limitations of viewing angles, complex and diverse security inspection images will also result. Recognition job increased difficulty
[0004] The complexity of an image is determined by multiple factors, and it is difficult to quickly and accurately analyze the complexity of an image using a simple method

Embodiment Construction
[0025] Aiming at the deficiencies of the prior art, the present invention proposes an intelligent method for analyzing the complexity of the security inspection image, through intelligent analysis of the complexity of the security inspection image, and then according to the complexity of the image, it quickly reminds the security inspection when the object under test passes through the security inspection machine The security inspectors are even alerted to the detected object, and even prompt the security inspector to open the bag for inspection of the detected object. An intelligent method for security image complexity analysis of the present invention comprises the following steps:
[0026] (1) Obtain an X-ray image of the detected object;
[0027] (2) analyzing the size of the detected line bag according to the X-ray image;
[0028] (3) According to the X-ray image, analyze the pixel density distribution of the detected line package in the X-ray image. The pixel density di...

The invention discloses an analysis method for security inspection of image complexity. First, an X-ray image of detected objects is acquired; then, the size of the detected objects, pixel density distribution of the detected objects in the X-ray image, the number of contour lines of each of the detected objects, the length of the contour lines of each of the detected objects, the maximum stacking number of layers of each of the detected objects, energy generated after X rays penetrate through the detected objects, effective atomic numbers of the detected objects and similarity to forbidden items are obtained; next, the complexity of the detected objects is generated and obtained, and a security inspector is reminded to inspect the detected object with the maximum complexity according to the complexity of the detected objects.
Description
technical field [0001] The invention relates to the technical field of application of security inspection images, in particular to an analysis method for the complexity of security inspection images. Background technique [0002] Today, with the increasingly severe security situation, countries have put forward higher requirements for the safety of public places, especially in public places such as airports, stations, docks, and customs, and have taken measures to strictly inspect passenger luggage, cargo containers, etc., among which , The security inspection technology provided by the security inspection system is mostly radiation imaging technology. Subway, airports and stations have a large flow of people, the security inspection equipment runs fast, passengers carry a lot of items and place them in various ways, and the security images formed when passing through the security inspection machine are complex, which has caused great difficulties for the security inspectors...
