Embodiment 1

[0036] In the prior art, the recognition of vehicle information based on image patterns mainly relies on the acquisition of vehicle license plate images to obtain the digital information of the vehicle. The vehicle license plate is used as the identification of the vehicle identity. It is composed of the license plate number and color. The number is the vehicle registration number, which is unique and is the main source of information for social management of vehicles; based on the radio frequency identification vehicle information is mainly fixed on the front windshield of the vehicle "Taoji passive radio frequency tag" As a technology for vehicle identification. This technology is to store the digital attribute of the vehicle identity in the radio frequency tag in advance, which can be directly read by the computer, so the recognition reliability of this technology is high. An anti-tampering device is installed between the electronic tag and the front windshield of the vehic...

Abstract

The invention discloses a vehicle identity recognition method based on image enhancement, and relates to the field of image processing and recognition. The method comprises the following steps of 1, acquiring a vehicle license plate and a vehicle radio frequency tag to obtain a license plate picture and the radio frequency data; 2, after the image enhancement is carried out on the license plate picture, identifying the vehicle license plate to obtain a license plate identity identification result; 3, identifying the radio frequency data to obtain a radio frequency identification result; and 4, fusing the license plate identity recognition result and the radio frequency identity recognition result, and outputting a final recognition result according to a set confidence coefficient. According to the invention, the collected vehicle identity image is enhanced, the integrity of the acquired image is ensured, the subsequent accurate identification is facilitated, the dual-mode identification is performed based on the image and radio frequency, the data is outputted according to the confidence coefficient, the resource occupation difficulty caused by the combination of the two is overcome, the occupied resources are saved, the identification efficiency is improved and the identification accuracy is improved.

Description

technical field [0001] The invention relates to the field of image processing and recognition, in particular to a vehicle identity recognition method based on image enhancement. Background technique [0002] The main media for human beings to transmit information is language and images. According to statistics, visual information accounts for 80% of the various information received by human beings, so image information is a very important medium and way of information transmission. The image transmission system includes six parts: image acquisition, image compression, image coding, image storage, image communication, and image display. In practical applications, each part may cause image quality to deteriorate, so that the information conveyed by the image cannot be read and recognized normally. For example, in the process of image acquisition, the overall illumination of the image is uneven due to the lighting environment or the reflection of the surface of the object, or...
