Safety check image coloring method, device, storage medium and computer equipment

Abstract

The invention provides a safety check image coloring method, a device, a storage medium and the computer equipment. According to the invention, an original high-low-energy image is input into the image coloring model, the ab coloring channel data corresponding to the original high-low-energy image can be obtained, the L channel data based on the original high-low-energy image and the ab coloring channel data output by the image coloring model can be obtained, and the image coloring efficiency is improved. Lab color space data corresponding to the original high and low energy image can be obtained; according to the invention, the image coloring model is used for coloring the original high-low energy image collected during safety check, so that a mode of performing material classification and coloring after calculating a corresponding atomic number through a high-low energy experimental data derivation formula in the prior art is eliminated; the conditions that atomic number calculation is inaccurate and a many-to-one relationship exists between the proton ordinal number and the color space during atomic number calculation are avoided, so that the image coloring accuracy is effectively improved.

Description

technical field [0001] The invention relates to the technical field of security checks, in particular to a security check image coloring method, device, storage medium and computer equipment. Background technique [0002] Security inspection machine is a common security inspection tool, widely used in transportation, venue security inspection and other fields. When the security inspection machine conducts security inspections on items, it mainly uses X-ray sources to emit high and low energy rays. After the receiving board receives high and low energy rays to obtain high and low energy data, it calculates the corresponding atomic number through the high and low energy data and then performs material classification. And color it. The color of the item is mainly based on the calculated atomic number and high and low energy fusion map data to generate corresponding color data. It is usually defined that organic substances are displayed as orange or yellow series, inorganic su...
