Abstract

The invention relates to a security check and identification system and a control method thereof. According to the security check and identification system based on integration of a reinforcement learning algorithm and an attention area generation network comprises an object feature extraction module, a hazardous article region segmentation module, a preliminary classification module, a preliminary classification result determination module, and a fine graining identification module. According to the invention, with optimization of the hazardous article region segmentation module and setting of the fine graining identification module, the security checking accuracy and security checking efficiency are improved substantially; the security checking time is shortened; the congestion situationis alleviated; the manpower resources are saved; and the work pressure of the security checking staff is reduced.

Description

technical field [0001] The invention relates to a security inspection identification system and a control method thereof, belonging to the technical field of object identification. Background technique [0002] With the continuous enhancement of safety awareness, security inspection equipment has been installed in important areas such as subway stations, railway stations, and airports. At present, the identification of dangerous goods is mainly based on manual identification. Such an identification method requires training for the staff, and the accuracy cannot be guaranteed, and it is prone to missed and wrong judgments. In addition, areas such as subway stations are crowded with people, and relying on manual identification will lead to low efficiency of security checks. Therefore, we urgently need an efficient automatic security check identification system. Contents of the invention [0003] The object of the present invention is to provide a security inspection ident...
