Multi-energy spectrum x-ray imaging systems and methods for recognizing article using multi-energy spectrum x-ray imaging system

A multi-energy spectrum X-ray imaging system for recognizing an article, comprising:

• an X-ray source configured to generate X-rays under the control of a scanning controller;
• the scanning controller configured to control the X-ray source according to a selected parameter mode;
• a detector configured to receive X-rays which are emitted from the X-ray source and are transmitted or scattered through the article and convert them into an output signal;
• a processor configured to:
• recognize an application scenario and/or priori information of the article, select a parameter mode suitable for the article from a plurality of parameter modes stored in the multi-energy spectrum X-ray imaging system based on the recognized application scenario and/or priori information, wherein the plurality of parameter modes comprise a common parameter mode and a high performance parameter mode, and a high performance parameter mode, and receive an output signal from the detector and recognize the article using the output signal;
• and
• a memory configured to store the plurality of parameter modes,
• wherein the plurality of parameter modes are obtained by optimizing system parameters of the multi-energy spectrum X-ray imaging system under a specific condition using a training sample library for various articles.

A non-transitory computer-readable medium comprising instructions that, when executed by a processor, perform operations of:

• recognizing an application scenario and/or priori information of the article;
• selecting a parameter mode suitable for the article from a plurality of parameter modes stored in the multi-energy spectrum X-ray imaging system based on the recognized application scenario and/or priori information, wherein the plurality of parameter modes comprise a common parameter mode and a high performance parameter mode;
• and
• recognizing the article using the selected parameter mode,
• wherein the plurality of parameter modes are obtained by optimizing system parameters of the multi-energy spectrum X-ray imaging system under a specific condition using a training sample library for various articles.
