Problems solved by technology

Since it is difficult to accurately reconstruct the object section from the projections from a few viewing angles, the detection error of this technology is relatively large
[0006] In addition, prior art documents 1-2 are all safety detection methods for general liquids, and do not involve safety detection methods for certified liquids

Embodiment 1

[0067] For a schematic structural view of the safety detection device of Embodiment 1, see figure 1 . The workflow is as follows:

[0068] 1) Utilize the barcode scanner 1 to scan the barcode on the container 6 containing the liquid to be detected;

[0069] 2) Place the container 7 containing the liquid to be detected on the moving device 3;

[0070] 3) The computer 6 controls the radiation source 2 to turn on the radiation through the controller 5, and simultaneously controls the movement device 3 to move horizontally, and at the same time sends a collection command to the computer 6;

[0071] 4) The computer 6 controls the detector 4 to obtain transmission image information, the detector 4 sends the collected information to the computer 6, and the computer 6 processes the received transmission image information and compares it with the standard data stored in the database, and then judges Liquid safety properties;

[0072] 5) Display the judgment result on the monitor of...

Abstract

The invention discloses a security detection method and device for authenticating liquid; the security detection method comprises the following steps of: a. scanning a bar code on a tested liquid container, and searching transmittance image information to which the bar code corresponds in a database; b. placing the container containing the tested liquid on an X-ray perspective device; c. obtaining the transmittance image information of the tested liquid and the container through the X-ray perspective device; and d. comparing the transmittance image information in the step a and the transmittance image information in the step c. The security detection method has high detection accuracy; and the security detection method is more convenient to operate.

Description

technical field [0001] The invention relates to a safety detection method and a device thereof, in particular to a safety detection method and a device for authenticating liquid. Background technique [0002] At present, security inspection technologies using X-ray fluoroscopy mainly include single-energy fluoroscopy, dual-energy fluoroscopy, and multi-view technology (see prior art documents 1-2). [0003] Single-energy fluoroscopy technology is the earliest X-ray safety detection technology used. It can only obtain the shape information of the object in the package, but not the material information. It has been phased out at present, but it is still used in some occasions with relatively low detection requirements. used. [0004] Dual-energy fluoroscopy technology is currently the most widely used technical means in X-ray fluoroscopy safety detection technology on the market. It obtains the high and low energy projections of objects without object occlusion by means of ma...
