Description

Technical Field

[0001] The invention relates to a passenger car security inspection method, device and system. Background Art

[0002] Usually, vehicles need to undergo security inspections when entering and exiting, at ports, at highway checkpoints, and in urban security situations, and a decision on whether to release the vehicle is made based on the inspection results. Common inspection methods include: manual inspection, small handheld detection equipment, and informant reports; in the use of common inspection methods, there are obvious defects: 1. Manual inspection requires security personnel to check every suspicious area of ​​every vehicle, but supervisors have limited work energy and it is difficult for them to concentrate their attention for a long time and efficiently check every area of ​​every vehicle to be inspected, and the ability of security personnel varies due to personal emotional factors, personal experience factors, etc.; 2. Handheld detection equipment must be equipped by each supervisor, and this type of equipment has a single detection function and is difficult to cover the requirements of various scenarios. In addition, the equipment hardware is updated quickly, and the elimination and failure rates are high; 3. Informant reports are more accidental, and training informants requires a lot of human and material resources;

[0003] The above common inspection methods will greatly increase the inspection cost. During the peak period of vehicle in and out, more supervisors and equipment need to be arranged to ensure the normal vehicle traffic speed and inspection effect, which requires a lot of manpower and material resources.

[0004] Moreover, there may be cases of missed inspection or evasion of inspection. In addition, for vehicles with problematic inspection results, it is difficult to match vehicle information with security inspection information, and it is difficult to trace back later, so the effect of the above method is relatively limited.

[0005] Therefore, there is a need for a security inspection method, device and system that can improve efficiency, reduce costs and reliably screen out items to be reviewed and suspected areas. Summary of the invention

[0046] 1. Without affecting the existing security inspection efficiency, the present invention can obtain the video of the passenger driving to the inspection location, the generated license plate image, the vehicle appearance image and the vehicle X-ray image. When there are contraband or abnormal items in the vehicle, the license plate image and vehicle appearance image of the suspected vehicle can be quickly located, solving the problem of the difficulty in quickly locating the problem vehicle due to the busyness of the inspectors in the traditional security inspection process, resulting in missed inspection, escape from inspection and difficulty in later tracing;

[0047] 2. The present invention can flexibly adjust the scope of identified commodities in real time according to different inspection requirements on site, has excellent recognition rate and can perform customized key detection on contraband that is prone to appear in different scenes, which is more intelligent and targeted;

[0048] 3. The present invention scans the vehicle X-ray image in real time. At the same time, the system determines and displays whether there are any contraband or suspicious items in the vehicle to be inspected within seconds. Vehicles without suspicion can be released directly, and suspicious vehicles are manually checked according to the suspected areas displayed by the system, which greatly improves the speed of normal vehicles and the inspection efficiency of suspicious vehicles, saving a lot of manpower and material resources;

[0049] 4. When suspected contraband or abnormal items are found during security checks, the system page will automatically alarm. The alarm will not stop until the security personnel handle the situation and register the results. Registering the processing results requires security personnel to have a stronger sense of responsibility and a more rigorous work attitude, which plays a supervisory role. On the one hand, it can prevent security personnel from missing suspicious vehicles. On the other hand, the recorded processing results can also be used as a basis for later analysis and tracing, which is convenient for formulating more targeted security inspection processes.
