Description

Technical Field

[0001] This utility model belongs to the field of vehicle safety inspection technology, specifically relating to a vehicle chassis imaging inspection device. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] According to safety management requirements, motor vehicles entering the safety control area need to be inspected to ensure that the inspected vehicles are not carrying prohibited items. Among them, the chassis inspection of vehicles is difficult to operate and is prone to oversights due to the low position of the chassis, the complex structure of the chassis and the many hidden corners.

[0004] To improve the efficiency of vehicle chassis inspections, staff typically use chassis safety inspection devices. These devices capture images via camera and transmit them to a computer to generate images of the vehicle chassis. Inspectors then review these images to conduct a thorough inspection of the chassis, preventing the presence of prohibited items.

[0005] However, current vehicle undercarriage imaging devices on the market primarily image the vehicle chassis by placing the device on the ground with the camera facing the chassis. Because the camera is relatively close to the chassis, the imaging principle causes perspective distortion in the images, resulting in images where objects appear larger than distant objects. This distortion leads to poor image quality, unclear structure, and discrepancies with the actual chassis, making it easy for inspectors to misjudge the vehicle's undercarriage. This is especially problematic for vehicles with low chassis clearance, where the camera must be chosen to ensure image quality, thus requiring a certain size and making it inconvenient to place it under the chassis. Even when placed under the chassis, the distortion problem is exacerbated, further hindering vehicle safety inspections. Utility Model Content
