Abstract

The invention provides a vehicle axle number determination method and device, and the method comprises the steps: obtaining the infrared video data of a monitoring region, carrying out the image enhancement of a current frame image of the infrared video data, and obtaining an image enhancement image of the current frame image; determining a foreground image of the current frame image according tothe image enhancement image; determining a single vehicle image in the current frame image according to the foreground image and the image enhancement image; and determining the axle number of each vehicle in the current frame image according to the single vehicle image. The problem of low identification precision of a vehicle axle number identification mode in related technologies can be solved,the vehicle axle number identification in a highway free flow scene is performed by adopting an infrared thermal imaging technology, and the vehicle axle number identification precision is improved.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and a device for determining the number of axles of a vehicle. Background technique [0002] At present, the expressway toll has changed from the previous toll by weight to toll by axle type. The prerequisite for toll by axle type is to identify the number of axles of the vehicle. Therefore, it is of great significance to install the vehicle axle number recognition system on the expressway. [0003] Since it is to identify the toll vehicle axle type of the vehicle in a single-lane low-speed environment, to detect the toll vehicle model in a high-speed multi-lane free-flow environment, especially to identify the number of vehicle axles, using current technical methods, such as laser recognition technology, video recognition technology, Weighing recognition technology will inevitably have problems such as difficult recognition or low recognition accuracy, and the...
