Abstract

The present invention provides a method and device for detecting vehicles with license plates. The method includes: extracting the first sub-image corresponding to the vehicle to be queried in the image to be queried, wherein the first sub-image includes a recognizable license plate number; license plate number, determine the model information of the vehicle to be detected; according to the model information, obtain all sample images in the model database corresponding to the model information from the pre-established database; judge the first sub-image and all sample images in the model database Whether it matches; if it does not match, it is determined that the vehicle to be inquired is a deck car; wherein, the database includes: a variety of vehicle models databases, and each vehicle model database includes: a collection of multiple sample images of the vehicle model; Sample images include: vehicle images under different lighting conditions, vehicle images from different shooting angles, and vehicle images in different scenes. The above method can more accurately and simply determine whether the vehicle to be queried is a licensed vehicle.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and device for detecting vehicles with license plates. Background technique [0002] With the rapid development of my country's economy, the continuous expansion of urban scale, and the substantial increase in the number of vehicles, my country's transportation system is gradually becoming intelligent. In order to achieve a certain purpose, some vehicles change or forge license plates, or use other license plates (decks). Vehicle detection technology is facing an urgent need. In the prior art, generally, the license plate number of the inquired vehicle is firstly identified, and then the vehicle model information is read from the database through the license plate number, and then compared with the detected vehicle model to determine whether it is a licensed vehicle. Among them, the methods of detecting vehicle models are generally divided into two t...
