Vehicle weight determination method, device and equipment and computer readable storage medium

Abstract

The invention discloses a vehicle weight determination method, device and equipment and a computer readable storage medium, and the method comprises the steps: obtaining a tire image of a vehicle, andcarrying out the preprocessing of the tire image; performing image segmentation on the preprocessed tire image, and obtaining the vertical deflection and the radial rigidity of the tire according tothe segmented tire image; calculating the load of the tire according to the vertical deflection and the radial rigidity of the tire; and obtaining the weight of the vehicle according to the load of each tire in the vehicle. According to the technical scheme, the tire image is obtained, the vertical deflection and the radial rigidity are obtained from the tire image, the load of the tire is calculated according to the vertical deflection and the radial rigidity, and the weight of the vehicle is obtained according to the load of each tire in the vehicle, so that the weight of the vehicle is determined automatically in a non-contact mode; therefore, vehicle congestion is avoided, the weight of all the vehicles is determined by acquiring the tire images of all the vehicles, and the convenience, stability and accuracy of vehicle weight determination are improved.

Description

Technical field [0001] The present application relates to the field of vehicle weighing technology, and more particularly, to a method for determining the weight of the vehicle, means, apparatus and computer-readable storage medium. Background technique [0002] In recent years, as competition infrastructure construction, industrial production, the rapid growth of trade business logistics, transportation industry become more intense, means of transport overrun excess exhibited uncontrollable increase in the state, which would easily lead to roads, bridges the occurrence of damage, and accidents not only cause heavy losses to public property, and would seriously endanger the lives of the people. [0003] To prevent an overloading overrun occurs, at present, the transport sector approach is to use a portable device weighing a random sample or platform provided for detecting the vehicle weight in a high speed toll station, however, this approach is prone to undetected and easily cau...

Problems solved by technology

[0003] In order to prevent the occurrence of overweight vehicles, currently, a method is that the traffic department uses portable weighing instruments to conduct random spot checks or set up weighbridges at high-speed toll stations for vehicle weight detection. However, this method is prone to missed inspections and is easy to Another approach is to use contact sensors, strain gauges, etc. to achieve vehicle congestion. Specifically, load cells are placed at the bottom of the bridge to collect bridge responses and identify information such as vehicle axle loads, or the sensors are set at On the tires, the dynamic vertical load of the vehicle is detected during the running of the vehicle, but the service life, measurement accuracy and measurement stability of the load cell installed at the bottom of the bridge have great limitations

In addition, the sensors installed on the tires will be adversely affected by the mutual vibration between the tire and the road surface, the frictional heat generated by the tires, etc., making it difficult to detect the weight of the vehicle efficiently and accurately.
