Abstract

The invention relates to a method and system for regularly detecting an X-ray machine image resolution testing body, and belongs to the technical field of image resolution. The method includes the following steps of S1, image testing, S2, zone locating, S3, TEST1 detecting algorithm testing, S4, TEST2 detecting algorithm testing, S5, TEST3 detecting algorithm testing, and S6, TEST4 detecting algorithm testing. The method and system for regularly detecting the X-ray machine image resolution testing body intends to integrate leading edge theories of compute vision and mode recognition and develops an automatic regular checking technology of an X-ray security checking machine based on intelligent image analyzing, and through automatic analyzing of imaging of a standard testing box, whether the performances of the line resolving power, penetrating resolving power, space resolving power, penetrating power and the like of the X-ray security checking machine are up to standard or not are accurately and objectively diagnosed in real time to give expert-level opinions on whether security devices can be normally used or not.

Description

technical field

[0001] The invention belongs to the technical field of image analysis, and relates to a method and system for X-ray machine image resolution test body regular inspection. Background technique

[0002] The X-ray security inspection machine is mainly used to perform perspective scanning on luggage and items other than the human body, and obtain different images of different items, so as to find dangerous items hidden inside. The equipment sends the luggage to be inspected into the X-ray inspection channel by means of the conveyor belt, and triggers the X-ray source to emit X-ray beams. The X-ray beam passes through the object to be inspected, and part of it is absorbed and bombards the semiconductor detector installed in the channel. The detector converts X-rays into signals, and finally converts them into X-ray images, and the security inspectors identify whether there are dangerous items (knives, firearms, drugs, flammable, explosives, etc.).
