Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044]Embodiments of the present invention provide a vehicle identification method for high-speed toll stations based on vehicle length detection, such as figure 1 As shown, the method is implemented through the following steps:

[0045] Step 101: The computer performs edge detection on the collected lane image when the vehicle is in the lane and the corresponding empty lane image, and then performs difference to obtain a difference image.

[0046] Specifically, the lane image and the corresponding empty lane image when the vehicle is in the lane may be collected by a camera.

[0047] Edge detection is performed on the lane image when the vehicle is in the lane and the corresponding empty lane image to reduce the amount of subsequent calculations, and then the image is enhanced according to the morphological features, and finally the noise i...

Abstract

The invention discloses a vehicle identification method at a high-speed toll station based on vehicle length detection. A computer performs edge detection on the collected lane image when the vehicle is located in the lane and the corresponding empty lane image, and then makes a difference to obtain a differential image. The differential image is processed to separate the lanes to obtain the vehicle image after the lane is removed, and finally the length of the vehicle in the vehicle image is recognized to obtain the actual length of the vehicle; the invention also discloses a vehicle identification device for a high-speed toll station based on vehicle length detection, The actual length of the vehicle can be accurately detected by the invention.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a vehicle identification method and device at a high-speed toll station based on vehicle length detection. Background technique [0002] With the rapid development of social economy, the rapid growth of the automobile industry is driven, and motor vehicles such as automobiles have become one of the indispensable means of transportation in the current society. The problem of toll collection on expressways has become a widely concerned issue. Existing high-speed toll collection methods mainly include the following two methods: [0003] 1. Charge by weight is adopted. A dynamic scale is used, and there will be a deviation of plus or minus 5%, which is likely to cause collection disputes. [0004] 2. License plate recognition system in the driveway. The recognition rate of the license plate is generally not high, which affects the operation speed, especially now th...
