Problems solved by technology

[0004] However, due to the defects of X-ray scanning, the scanned images often have problems such as blurring and incomplete display. Moreover, due to the complexity and diversity of contraband targets, the detection results of contraband targets only rely on contour features. High missed detection rate and false detection rate

Abstract

Embodiments of the present invention provide a contraband target detection method, device, and computer equipment. The method includes: performing enhancement processing on specified features in an X-ray image to be detected through a variety of preset image enhancement methods to obtain a plurality of enhanced images; Use the preset target detection method to detect each enhanced image, determine whether there is a target of contraband to be determined in each enhanced image, and determine the location information of the area where the target of contraband to be determined is located; If the number of enhanced images reaches a preset threshold, extract the region of interest image corresponding to the position information from the X-ray image to be detected; obtain and determine the substance category of the target of contraband to be determined according to the attribute characteristics of the region of interest image; If the substance category conforms to the preset substance category, the detected target of contraband to be determined is determined as the determined target of contraband. Through this scheme, the missed detection rate and false detection rate of contraband target detection can be reduced.

Description

technical field [0001] The invention relates to the technical field of security inspection, in particular to a contraband target detection method, device and computer equipment. Background technique [0002] With the rapid development of the logistics industry, the phenomenon of transporting contraband by means of express delivery and logistics entrainment emerges in an endless stream. This method of entrainment transportation is highly concealed, difficult to investigate, and endangers public security. Traditionally, X-ray security inspection machines are used to detect contraband in luggage and packages. By imaging X-ray transmission luggage and packages, the purpose of item inspection without unpacking can be achieved. It has been used in airports, customs, railway stations, subway stations and other places. widely used. However, the method of using X-ray security inspection machines to detect contraband requires staff to participate in image discrimination, and the degr...
