Abstract

The invention discloses a license plate recognition method and device and an inspection vehicle. The method comprises the steps that a first frame image and a second frame image of a vehicle are acquired and recognized respectively, and a first recognition result (including first license plate information and a first credibility value of the first license plate information) and a second recognition result (including second license plate information and a second credibility value of the second license plate information) are obtained; combining the first recognition result and the second recognition result according to the first credibility value and the second credibility value to obtain a first combined result; obtaining a next frame of image of the second frame of image for recognition, and combining the first combination result with an recognition result corresponding to the next frame of image to obtain a second combination result; and until the last frame of image in the video stream of the same vehicle is obtained, determining the license plate information of the vehicle according to the license plate information in the merging result determined by the last frame of image. Theproblem that license plate information recognized in an existing license plate recognition mode is inaccurate is solved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular, to a license plate recognition device and inspection vehicle. Background technique [0002] License plate recognition is required in many situations such as illegal capture or parking charges. The current way of license plate recognition is mainly based on the pictures captured by the camera, and then image analysis is performed on the pictures to identify the license plate information contained in them. However, this This method only analyzes based on a small number of pictures. If each picture is not clear, it will lead to the problem of inaccurate license plate information finally recognized. Contents of the invention [0003] The main purpose of this application is to provide a method and device for license plate recognition and an inspection vehicle to solve the problem of inaccurate license plate information identified by the existing license plate recogni...
