Abstract

The present disclosure relates to a scanning image reconstruction method, inspection equipment and a computer-readable storage medium. The scanning image reconstruction method includes: causing the radiation source to send out beams of rays with various radiation energies to the inspected object moving relative to the radiation source according to the sub-sampling frequency, and the sub-sampling frequency is lower than the normal time to keep the obtained original scanning image continuous. Sampling frequency; obtain the undersampled image corresponding to each radiation energy, and perform image fusion on the undersampled image corresponding to various radiation energies to obtain the fused undersampled image; input the fused undersampled image to the In the deep learning model corresponding to at least one of the multiple radiation energies, a reconstructed image corresponding to at least one of the multiple radiation energies is obtained. The embodiment of the present disclosure can obtain a better image reconstruction effect.

Description

technical field [0001] The present disclosure relates to the field of radiation inspection, and in particular to a scanning image reconstruction method, inspection equipment and a computer-readable storage medium. Background technique [0002] In the field of container cargo / vehicle security inspection, X-ray perspective imaging technology is the most widely used method. This method utilizes that when X-rays pass through different objects, they are absorbed to different degrees, and different amounts of radiation can be collected on the detector. In order to further improve the quality of scanned images and realize the identification of different types of substances, on the basis of traditional X-ray scanning technology, related technologies have gradually developed dual-energy X-ray scanning systems and multi-energy X-ray scanning systems. [0003] Taking the dual-energy X-ray container inspection system as an example, this inspection system alternately generates two kinds...
