Description

Technical Field

[0001] The present invention relates to the technical field of vehicle security inspection, and in particular to a vehicle chassis imaging inspection device and a use method thereof. Background Art

[0002] According to safety management requirements, motor vehicles entering the security control area need to be inspected to ensure that the inspected vehicles do not carry any prohibited items. Among them, the chassis inspection of the vehicle is difficult to perform and is prone to omissions due to the low chassis position, complex chassis structure and many hidden corners.

[0003] In order to improve the efficiency of vehicle chassis inspection, the staff usually use chassis safety detection devices to inspect the vehicle chassis. The chassis safety detection device uses the camera to generate images and then sends them to the computer to generate vehicle chassis pictures. The inspectors can view the vehicle chassis pictures to conduct a detailed inspection of the vehicle chassis to prevent the vehicle chassis from carrying prohibited items.

[0004] However, the underbody imaging devices currently available on the market mainly image the vehicle chassis by placing it on the ground with the camera facing the vehicle chassis for shooting. In this method, since the camera is relatively close to the vehicle chassis, the captured picture has a perspective relationship due to the imaging principle, that is, the picture will be larger when it is near and smaller when it is far away, resulting in different degrees of distortion in the picture. The different distortions result in poor quality of the imaged vehicle chassis photos, unclear structure, and differences from the actual chassis, which makes it easy for staff to misjudge when inspecting the vehicle chassis; especially for vehicles with a low chassis height from the ground, the camera must ensure imaging quality when selected, and therefore has a certain size, which makes it inconvenient to set it on the vehicle chassis for imaging. Even if it is set on the vehicle chassis for imaging, the distortion problem of the image will be aggravated, affecting the vehicle's security inspection work. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a vehicle chassis imaging inspection device and a use method. The device is configured to have a flat structure so that the device can be conveniently arranged at the lower part of the vehicle chassis, and the camera is arranged inside the device to avoid damage. At the same time, the shooting direction of the camera is parallel to the vehicle chassis. The shooting path of the camera is extended by adding a reflector, the optical path and the lateral area of ​​the shooting are increased, and a radial shielding structure is arranged around the camera with the camera as the base point to avoid imaging interference, so that the device can achieve distortion-free imaging of the vehicle chassis, reduce the perspective situation of the obtained image where objects are larger near and smaller far away, obtain the real vehicle chassis structure, and ensure that the vehicle security inspection operation is completed efficiently and with quality.

[0031] In a typical embodiment of the present invention, a vehicle chassis imaging inspection device is proposed, including a device shell, a light assembly 1 is provided at one end inside the device shell, and a transparent cover 5 is provided on the top of the device shell corresponding to the light assembly 1; a camera assembly 3 is provided inside the end of the device shell away from the light assembly 1, and an inclined reflector 7 is provided on the side of the light assembly 1 close to the camera assembly 3, and the camera assembly 3 is arranged at a certain distance from the reflector 7; the shooting direction of the camera assembly 3 is arranged toward the inclined surface of the reflector 7.

[0032] With such a configuration, the shooting direction of the camera can be set to be parallel to the ground, rather than the traditional device camera directly facing the vehicle chassis, and the reflector 7 is added to extend the camera shooting path, increase the optical path and the horizontal area of ​​the shooting, and set a fan-shaped shielding structure around the camera to avoid imaging interference, so that the device can achieve distortion-free imaging of the vehicle chassis, reduce the perspective situation of the obtained image being larger near and smaller far away, obtain the real vehicle chassis structure, and ensure the efficient and quality completion of the vehicle security inspection operation. Especially for the vehicle chassis with low ground clearance, the imaging effect of the device provided by this embodiment is better.

[0033] Furthermore, the device housing includes a housing cover 14 and a lower housing 15. A transparent cover plate 5 is provided at a position on the housing cover 14 corresponding to the light assembly 1, and a sealing strip 10 is provided at the connection between the housing cover 14 and the lower housing 15.

In addition, in other embodiments of the present invention, the inclination angle of the reflector 7 can be set according to actual conditions, mainly to achieve clear and complete shooting of the vehicle chassis with the camera.

[0042] Furthermore, a shielding structure is provided in the device housing along the shooting path from the camera to the reflector 7 , and the shielding structure is configured as a channel structure that is radially oriented toward the reflector 7 with the camera as a base point.

[0043] In this embodiment, the shielding structure is configured as a channel structure that is radially directed toward the reflector 7 from the camera as a base point, such as Figure 1 As shown, the channel structure is connected to the upper shell cover 14 and the lower shell 15, so as to shield the camera's shooting angle and avoid interference with the camera's imaging.
