An imaging device and method for vehicle safety inspection

Abstract

The present disclosure relates to an imaging device and method for vehicle safety inspection, which belongs to the field of safety inspection. An imaging device for vehicle safety inspection includes: a radiation source device, including a first ray unit that emits a first ray beam along a first predetermined opening angle so that the first ray beam passes through The first part of the vehicle to be inspected passes through the inspection channel at a preset speed; the detector device includes a first detector unit arranged corresponding to the first ray unit, and the first detector unit is used to receive the first ray beam. Wherein, the radiation source device is at least partially disposed on the road surface of the inspection channel, and the first detector unit is disposed on the first side of the inspection channel. The imaging device and method for vehicle safety inspection according to the present disclosure can realize security inspection of whether illegal items are hidden in specific parts of the vehicle.

Description

technical field [0001] The present disclosure relates to the technical field of safety inspection, and in particular, to an imaging device and a method thereof for vehicle safety inspection. Background technique [0002] With the need to combat smuggling and security, the world is studying how to use more advanced technology to ensure social security and combat smuggling and terrorist crimes. [0003] Using freight or passenger vehicles as a tool to hide smuggled goods, weapons, explosives and other contraband in hidden places such as the interior of the vehicle and tires, so as to avoid inspection, enter government departments, important venues, customs and other areas, and carry out criminal activities, which is concealed Strong characteristics, relying on the traditional manual inspection method, not only low efficiency, slow speed, a lot of manpower and material resources, but also poor accuracy, so there is an urgent need for a method to quickly capture the hidden parts...

Problems solved by technology

[0003] Using freight or passenger vehicles as a tool to hide smuggled goods, weapons, explosives and other contraband in hidden places such as the interior of the vehicle and tires, so as to avoid inspection, enter government departments, important venues, customs and other areas, and carry out criminal activities, which is concealed Strong characteristics, relying on the traditional manual inspection method, not only low efficiency, slow speed, a lot of manpower and material resources, but also poor accuracy, so there is an urgent need for a method to quickly capture the hidden parts of the vehicle during vehicle traffic, so as to find prohibited items The system can be widely used in customs, government agencies, security departments, prisons, venues, competition venues, airports, restaurants, banks, ports, nuclear power plants and other places for security inspections

[0004] At present, the common technical solution for container vehicle inspection is to place the radiation source on the side of the inspected vehicle for imaging. Since the radiation source needs to have a certain installation height, the minimum scanning height of the equipment is not less than 0.5m, and the complete vehicle tires and the lower part of the vehicle cannot be scanned. Toolboxes or suitcases can only be solved by raising the height of the vehicle’s passing ground. Not only does the amount of civil construction work is large, but also for many container vehicle inspection equipment application scenarios, ground construction cannot be carried out. Therefore, the current general inspection technical scheme is There are loopholes in the inspection of vehicle tires, lower toolboxes, and trunks, which bring potential safety hazards

[0005] In addition, the current inspection technology for radiation imaging during vehicle traffic must avoid the cab for scanning in order to ensure the safety of personnel, and there will be people in the back row of the cab of small passenger vehicles, so the existing inspection technology cannot realize the detection of small and medium-sized vehicles. Inspection of hidden parts such as trunks, tires, and toolboxes of passenger vehicles. The current inspection technical scheme has potential safety hazards and risks in the inspection of small passenger vehicles.
