Intelligent security check method based on suspected dangerous goods evaluation

Abstract

The invention relates to an intelligent security check method based on suspected dangerous goods evaluation, and belongs to the technical field of security check, and the method comprises the following steps: obtaining the volume data of a packaged object through security check CT equipment, carrying out the feature value extraction of a segmented independent object, and obtaining a dangerous goods similarity rate vector of the object; and acquiring a dangerous goods classification identification probability vector of the goods by using a dangerous goods identification module, further performing dangerous goods comprehensive evaluation on the goods, and judging whether to give an alarm based on an evaluation result. According to the method, suspected dangerous objects are comprehensively recognized, missing detection events can be reduced, the security check efficiency can be greatly improved while the security check quality is ensured, and an effective guarantee is provided for application scenes needing high-precision security check.

Description

technical field [0001] The invention belongs to the technical field of security inspection, and in particular relates to an intelligent security inspection method based on evaluation of suspected dangerous goods. Background technique [0002] In daily security inspection, X-ray item security inspection machine is currently the most widely used main security inspection equipment. It is widely used in public security, transportation, government, large-scale event sites and other occasions. It is mainly aimed at knives, guns, liquid containers, etc., which have typical shape characteristics. Check for dangerous goods. In recent years, domestic and foreign manufacturers and scientific research institutions have explored and developed the intelligent identification function of dangerous goods based on deep learning technology, and established mature intelligent risk assessment methods and systems for inspected objects. [0003] In civil aviation, customs and other security inspe...
