[0025] The LED lamp includes an LED lamp driver 5 and an LED lamp bead 10, wherein the LED lamp driver 5 is connected to the LED lamp bead 10, the LED lamp driver 5 is arranged inside the housing, and the LED lamp bead 10 is arranged on the surface of the housing;

[0026] The network switch 4 and the adapter 7 are respectively arranged inside and outside the shell. The network switch 4 is respectively connected to the adapter 7, the first image sensor 1, the second image sensor 2, the third image sensor 3 and the photoelectric switch 9, and is used to transmit the signals of the first image sensor 1, the second image sensor 2, the third image sensor 3 and the photoelectric switch 9 to the external industrial computer via the adapter 7.

[0027] In this embodiment, an industrial computer provides power to the three-camera area array vehicle underbody security inspection intelligent scanning system. The industrial computer is connected to a 220V power supply and provides 12V and 24V power supplies to the three-camera area array vehicle underbody security inspection intelligent scanning system. The operating voltage of the network switch, the first camera, the second camera, the third camera, and the photoelectric switch is 12V, and the operating voltage of the LED light is 24V. The industrial computer receives various signals from the three-camera area array vehicle underbody security inspection intelligent scanning system via an adapter, including signals sent by the first camera, the second camera, the third camera, and the photoelectric switch. It can also send control signals to the three-camera area array vehicle underbody security inspection intelligent scanning system via a network relay to control the operation of the first camera, the second camera, the third camera, and the LED light. The industrial computer uses a PC to generate images and display the signals sent by the first camera, the second camera, and the third camera, thereby achieving vehicle underbody security inspection.

[0028] In this embodiment, the first lens 12 and the third lens 13 are tilted upwards towards the left and right sides respectively. The tilted upward setting allows the camera to obtain images of both sides of the bottom of the vehicle more accurately and clearly.

[0029] In this embodiment, the shell includes a face cover 18, an upper shell 15 and a lower shell 17. The top edge of the upper shell 15 is provided with a sealing groove 16, and a sealing strip (not shown in the figure) is placed in the sealing groove 16. The face cover 18 and the lower shell 17 are respectively combined with the top surface and the bottom surface of the upper shell 15, and the face cover 18 and the upper shell 15 are sealed by a sealing strip.

[0030] In this embodiment, a stainless steel folding handle 8 is further provided on the outside of the housing.

[0031] In this embodiment, the LED lens 11 is provided above the LED lamp bead 10 .

[0032] In order to achieve multi-angle lighting and thus clearly capture the bottom of the vehicle in all directions, multiple LED lights can be provided, with the LED beads of each LED light being located at different positions on the housing and connected to independent LED lamp drivers 5. In this embodiment, two LED lights are specifically provided, with the LED beads of each LED light being located on both sides of the housing surface.

[0035] In this embodiment, the first image sensor 1 , the second image sensor 2 , and the third image sensor 3 are all area array CCD sensors.

[0036] During operation, when a vehicle passes through the three-camera area array undercarriage security intelligent scanning system, photoelectric switch 9 is triggered to generate a detection signal. This detection signal is transmitted via network switch 4 and adapter 7 to the industrial computer. The industrial computer returns a control signal to activate the LED lights, providing fill light for the vehicle's undercarriage and activating the first, second, and third image sensors 1, 2, and 3. Light is reflected from the vehicle's undercarriage and passes through first lens 12, second lens 14, and third lens 13, respectively, to the photosensitive surfaces of first, second, and third image sensors 1, 2, and 3. These signals are converted into imaging signals and transmitted to network switch 4. From there, they are transmitted via network switch 4 and adapter 7 to the industrial computer, which uses a PC for imaging, display, and analysis. The first, second, and third cameras form the central main-view camera and two side-view cameras. The central main-view camera can capture the entire vehicle undercarriage, while the side-view cameras can capture details on the sides of the vehicle and the inside of the wheels.

[0037] Those skilled in the art can make various corresponding changes and modifications based on the above technical solutions and concepts, and all of these changes and modifications should be included in the scope of protection of the claims of this utility model.
