Embodiment 1

[0050] As shown in Figure 9, the present invention discloses a tire load acquisition method based on image recognition, including the following steps:

[0051] Obtain a tire image of the tire to be tested; detect the contact area and tire pressure between the tire and the ground from the tire image; input the contact area and the corresponding tire pressure into a load model to calculate the load of the tire.

[0052] In this embodiment, a vehicle weighing method based on image recognition is also disclosed, comprising the following steps:

[0053] Obtain the load of each tire of the vehicle to be tested through the above-mentioned image recognition-based tire load acquisition method;

[0054] Calculate the total weight of the vehicle to be tested according to the load of each tire of the vehicle to be tested.

[0055] In this embodiment, a computer system is also disclosed, including a memory, a processor, and a computer program stored in the memory and operable on the proce...

Embodiment 2

[0058] The second embodiment is an extended embodiment of the embodiment, and its difference from the first embodiment is that the specific steps of the vehicle weighing method based on image recognition are refined, and the specific steps of the vehicle weighing system based on image recognition The structure is refined:

[0059] In this embodiment, a vehicle weighing system based on image recognition is disclosed, the system includes a collection component and a data processing component, the collection component is used to collect tire images of each tire of the vehicle to be tested, and The tire image is sent to the data processing component, and the data processing component is used to detect the contact area and tire pressure of each tire and the ground from the tire image of each tire; input the contact area and corresponding tire pressure of each tire In the load model, the load of each tire is calculated, and finally the total weight of the vehicle to be tested is cal...

Abstract

The invention discloses a tire load obtaining method based on image recognition and a vehicle weighing method and a system. The method comprises the steps that tire images of all tires of a vehicle tobe detected are obtained and sent to a data processing assembly, and the data processing assembly is used for detecting the contact area and the tire pressure of all the tires and the ground from thetire images of all the tires; inputting of the contact area of each tire and the corresponding tire pressure into a load model is carried out, and calculating of the load of each tire is carried out;compared with the prior art, the tire load obtaining method, the vehicle weighing method and the system have the advantages that the measurement range is wide, no extra sensing equipment is needed, traffic is not required to be closed, long-term stable work is realized, and information integration is facilitated.

Description

technical field [0001] The invention relates to the field of image recognition weighing, in particular to an image recognition-based tire load acquisition method, a vehicle weighing method and a system. Background technique [0002] With the rapid development of the transportation industry, fast, long-distance, and heavy loads have become an important part and development trend of road freight, which also leads to increasingly serious overloading and overrunning. Overloaded and overrun vehicles will cause irreversible damage to roads, bridges and other infrastructure, not only causing huge economic losses, but also seriously threatening the lives of the people. [0003] With the in-depth integration of artificial intelligence and transportation industry, intelligent transportation system was born. The intelligent transportation system is a new type of information-based, automated, intelligent and socialized transportation system formed by transforming the traditional transp...
