How many ways to quickly detect contraband using a security checker?

In recent years, the performance of security equipment has improved a lot compared to previous years. Now used in express logistics, stations and other fields, Tianyan introduces you to the x-ray security inspection machine to identify prohibited items.
First, image monitoring and identification:
The image monitoring method discriminates the article directly from the x-ray image configuration, and thus, whether the object to be inspected is suspicious depends on the image on the monitor or the renderer. Unusual objects or foreign objects appearing on the display or monitor should be considered suspicious. Items that cannot be accurately identified should also be considered suspicious items, which should be carefully investigated and the image positioned as needed.
Second, color analysis and identification:
The color analysis method is based on the different material data, and the color of the X-ray image appears in a different color, and then the identification of the substance type. The various colors appearing on the monitor reflect the density, mass and quantity of the object, so the quality of the object can be evaluated based on the depth of the image.
Third, the level analysis and identification:
Investigate the overlapping images of objects, which can be overlapped from the margins where the objects are not overlapped. After analyzing the color and shape of the different layers, the original shape of the object is discriminated.
Fourth, the structure judgment and recognition:
A general object has its specific structure. After X-rays, it is found that something that should not be in the structure of the object has been found, or something that should be there is gone. If there is no battery, no magnetic bar or no speaker in the radio, it should cause a high degree of alertness.
V. Proportion judgment and recognition:
The images on the screen have a certain share relationship with the things. The object is placed on the side of the channel close to the x-ray source, the image is larger, placed on the side away from the x-ray source, and the image is smaller. Security personnel should constantly explore the image and the share rules of each model in order to accurately discriminate.
Sixth, comprehensive analysis and identification:
Security personnel should pay attention to the conditioning of the brightness on the monitor. The brightness is not suitable and will affect the viewing effect. The brightness of a typical image is not too deep. If suspicious objects are found, the brightness should be properly adjusted according to its shape and thickness to achieve the most satisfactory effect. The MEX system and the SMEX system are non-images with brightness enhancement, darkening, non-inversion and grayscale scanning. They provide great convenience for identifying objects and should be fully utilized. The images of the security inspection machines produced by various companies will be different. Of course, the rules are still respected. In order to thoroughly grasp these methods, it is necessary for the security inspectors to have a good understanding of the performance of the security inspection machine.
