Problems solved by technology

However, the problem with these detection methods is that individual vehicle-mounted goods may have thinner parts such as steel pipes, steel bars, brackets, etc. protruding out of the vehicle. These small objects may not be detected by the detection sensor, resulting in wrong measurement results.

Embodiment 1

[0035] Embodiment 1: see figure 1 and figure 2 , a vehicle ultra-wide and ultra-high detection device, including a detection door frame 10, a distance sensor, the distance sensor can use laser, radar, infrared and other types, an image acquisition module 20, the image acquisition module can use a video camera, a camera, a camera, image processing Module 30, server 50 and display module 60;

[0036] The beam 11 of the detection portal 10 is provided with at least one first distance sensor 41, and the two vertical beams 12 of the detection portal 10 are respectively provided with at least one second distance sensor 42 and at least one third distance sensor 43; The quantity of the first distance sensor 41 arranged on the beam 11 and the quantity of the second distance sensor 42 and the third distance sensor 43 arranged on the two vertical beams 12 can be properly adjusted according to the actual accuracy, and the typical quantity can be the first There are 2 distance sensors, ...

Embodiment 2

[0039] Embodiment 2: A method for detecting the ultra-width and ultra-height of a vehicle, using the ultra-width and ultra-height detection device for vehicles described in Embodiment 1, the specific steps are as follows:

[0040] S1: preset in the server 50 the height H and width W of the detection gantry 10, that is, the straight-line distance between the two vertical beams 12, the measurement error tolerance E and the size information of various existing license plates;

[0041] S2: The vehicle to be tested slowly passes through the detection portal 10 along the direction of the detection portal 10. The vehicle to be tested preferably passes through the vehicle positioning range 70, which is more beneficial to the distance sensor and improves the accuracy of the measurement results. All distance sensors transmit their readings to the server 50, and the image acquisition module 20 transmits the image of the vehicle to be measured collected to the image processing module 30 fo...

Abstract

The invention relates to a vehicle over-width over-height detecting apparatus and a detection method. The apparatus comprises a detection door frame, distance sensors, an image acquiring module, an image processing module, a server and a display module. The crossbeam and the two vertical beams of the detection door frame are respectively provided with at least one distance sensor. The detection ends of all distance sensors are directed towards the inner side of the detection door frame. The data output ends of all distance sensors are respectively connected with a first signal input end of the server. The image acquiring module is used for acquiring images of vehicles passing through the detection door frame. The signal output end of the image acquiring module is connected with the signal input end of the image processing module. The signal output end of the image processing module is connected with a second signal input end of the server. The signal output end of the server is connected with the signal input end of the display module. The apparatus which effectively prevents errors and realizes insignificant measuring errors not only makes the working efficiency improved but also alleviates the working intensity of workers.

Description

technical field [0001] The invention relates to the field of intelligent detection, in particular to a device and a detection method for detecting the super-width and super-height of a vehicle by using a distance sensor and image processing at the same time. Background technique [0002] Highway is an important infrastructure of the national economy. However, the overrun of vehicles is extremely destructive to the road surface, causing early damage to the highway, bridge collapse, environmental pollution, safety accidents, etc. [0003] Overrun mainly refers to the overweight, overlength, overheight and overwidth of the vehicle. In expressway traffic law enforcement, overweight detection scales are commonly used to detect whether the vehicle is overweight. To identify over-limit behaviors such as over-height, over-width, over-length, etc., law enforcement personnel generally rely on manual measurement by law enforcement personnel with a tape measure. The technology is backwa...
