Intelligent method for fusing X-ray dual-energy transmission with Compton backscatter images

Abstract

The invention provides an intelligent method for fusing X-ray dual-energy transmission with Compton backscatter images, and relates to an intelligent technique for fusing X-ray dual-energy transmission with Compton backscatter images in the technical field of radiation detection. The method mainly solves the technical problem that the prior detection image display lacks a method of fusing various types of information in one image for simultaneous display. The method mainly takes an image registration technique as a basis, utilizes an information fusion technique to combine X-ray dual-energy transmission images with Compton backscatter images to give full play to respective advantages, and simultaneously expresses information in various aspects from detected luggage on one fusion image so as to form a more simple and practical platform for displaying and analyzing fusion images. The method is suitable for security inspection display equipment needing to quickly and accurately acquire the information of detected luggage, particularly for equipment sensitively detecting high-density substances with small atomic number.

Description

technical field [0001] The invention belongs to the technical field of radiation detection, and in particular relates to a detection method in a dual-technology detection device combining X-ray dual energy transmission and Compton backscattering, namely: intelligent fusion of dual energy transmission and Compton backscattering images method. Background technique [0002] In recent years, various forms of terrorist incidents have occurred frequently around the world, and public safety has become the focus of attention of the international community. With the continuous development of the international anti-terrorism situation, users' demands for new and new security inspection equipment continue to increase, and the detection method combining X-ray dual energy transmission and Compton backscattering has also attracted more and more attention. X-ray dual-energy transmission images can better reflect substances with high atomic numbers (such as metals) that are not easily pene...

Problems solved by technology

[0003] However, in the current foreign or domestic X-ray dual-energy detection equipment combined with Compton backscattering, the transmission image and the backscattering image are displayed separately, and the transmission image and the backscattering image are not fused. Moreover, there is no corresponding relationship established between the two images, and inspectors can only make interpretations by observing the images on the two monitors separately.

Therefore, this kind of equipment has two shortcomings: first, the complementarity between the scattering image and the transmission image is not reflected most intuitively, often relying on the experience of the inspectors to compare the observations, and artificially judge the information obtained. It is easily affected by the subjectivity of personnel; second, when the security inspection site is busy and the packages are passed continuously, the inspectors may reduce the inspection efficiency because they are tired of switching observations between the two monitors of transmission and backscattering, and more importantly, some Important information may be overlooked, resulting in missed or misjudgment
