At present, the types of vehicle tolls for overtaking lanes in high-speed entrances and exits can also be distinguished by the number of wheels. Trucks, 3-axle cars, 4-axle cars, 5-axle cars and 6-axle cars; however, most of them are manually confirmed, or ground-inductive methods are used, that is, induction equipment is laid on the ground to sense the number of wheels, or simply The vehicle type identification method is used to distinguish
[0003] However, the disadvantages of the manual method: the manual identification method has high accuracy, but for a long time, people will feel tired, errors will occur, and the efficiency is low; the way of sensing equipment: the method of laying sensing equipment has high accuracy, but the sensing equipment is due to Long-term crushed by trucks loaded with goods, it is easy to damage, and the replacement of equipment needs to close the road, the construction is complicated and extremely inconvenient

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the drawings.
[0026] figure 1 It shows a schematic diagram of the installation of a device for acquiring front image information and side image information of a vehicle according to an embodiment of the present disclosure. Such as figure 1 As shown, the image information used to obtain the front image information of vehicles passing by at high-speed entrances and exits is mainly to capture pictures of the front of the vehicle, which can be realized by using image capture equipment such as high-definition vehicle capture machine 2. At a high point, take pictures of oncoming vehicles, the number of which is preferably set at each toll gate of a toll station 1; it is used to obtain the side image information of vehicles passing by the high-speed entrance and exit, mainly to capture the picture of the side of the vehicle Or continue to record the side of the vehicle, which can be achieved by ...

The invention, which belongs to the technical field of intelligent traffic management, relates to a vehicle charging type discrimination method and device based on vehicle type identification and axledetection thereby solving technical problems of low intelligent degree and low identification rate in a current highway charging system. The method comprises the following steps: acquiring front image information and side image information of a vehicle; determining a license plate color and a vehicle type based on the acquired front image information of the vehicle; determining the number of wheels based on the acquired side image information of the vehicle; determining and outputting a charging type according to the obtained license plate color, vehicle type and wheel number. The charging types comprise a two-axle passenger car, a two-axle truck and an N-axle truck, wherein N is greater than 2. According to the invention, license plate and vehicle type identification and axle detection modes are combined, the comprehensive strategy of the license plate, vehicle type and wheel number information is fused to output the final charging type; the intelligent degree is high, the identification rate is high, and the application is stable.
Description
Technical field [0001] The present invention relates to the technical field of intelligent traffic management, in particular to a method and device for discriminating vehicle charging types based on vehicle type recognition and wheel axle detection. Background technique [0002] At present, expressway tolls collect the toll of the vehicle by adopting the weight-based tolling model. That is, the actual axle type of the vehicle is used to obtain the load limit, and the vehicle that exceeds the load limit is used to increase the charge. By adopting this method, it not only protects the highway pavement, bridges and other infrastructures, but also effectively curbs the overloading of vehicles, forcing transporters to reduce the weight of the loaded goods, thereby effectively reducing the excessive damage to the highway pavement by overloaded transport vehicles. Occurs, but also improves the safety of the vehicle. As more and more vehicles pass on the expressway, there are often som...
