Foreign matter detection system, method and device based on x-ray imaging technology

Abstract

The invention provides a foreign matter detection system based on X-Ray imaging technology, comprising a detection control module (5), and the detection control module (5) comprises the following modules: data acquisition module: obtained according to the X-ray imaging system (3) The imaging data generates a point-volume gray-scale array D; data processing module: processes the point-volume gray-scale array D to obtain a boundary area array A; foreign object confirmation module: generates foreign object identification information according to the boundary area array A. Correspondingly, the present invention also provides a foreign matter detection method and device based on X-Ray imaging technology. The X-Ray inspection system used in the present invention is automatically judged by software, which not only realizes the high-speed detection and judgment that is impossible to do manually, but also can achieve the judgment precision and accuracy that cannot be recognized by human eyes.

Description

technical field [0001] The invention relates to the field of detection of food, medicine and fine chemical industry, in particular to a foreign matter detection system, method and device based on X-Ray imaging technology. Background technique [0002] Foreign matter detection: To detect whether there are inedible or malignant foreign matter that may cause harm to the human body or key equipment in raw materials, semi-finished products and products, and is used to ensure the safety of food and medicine. Most of the existing technologies are metal detectors that use the principle of electromagnetic induction or eddy current induction, but these metal detectors have two obvious limitations, one is that they cannot detect non-metallic foreign objects such as stones and glass, and the other is that they are aimed at salt and moisture content. Larger products, due to the material effect brought about by the electrical conductivity and magnetic permeability of the material itself, ...

Problems solved by technology

Most of the existing technologies are metal detectors that use the principle of electromagnetic induction or eddy current induction, but these metal detectors have two obvious limitations, one is that they cannot detect non-metallic foreign objects such as stones and glass, and the other is that they are aimed at salt and moisture content. Larger products, due to the material effect brought about by the electrical conductivity and magnetic permeability of the material itself, will significantly affect its detection effect on metal foreign objects, especially non-magnetic stainless steel and other metals

[0003] The X-Ray inspection system commonly used in airports and stations for baggage security checks is imaged by X-Ray and manually judged whether there are dangerous objects. It cannot realize automatic judgment by software, and thus cannot realize high-speed detection and judgment that cannot be done manually. It cannot achieve the discrimination precision and accuracy that cannot be recognized by the human eye
