Method and system for identifying automobile tire number

Abstract

The invention discloses a method and a system for identifying an automobile tire number. The method comprises: a step of capturing a true-color image of the tire number; a step of converting the true-color image of the tire number into a digital bitmap; and a step of processing the digital bitmap and identifying the tire number. The step of processing the digital bitmap and identifying the tire number comprises: a step of performing grey processing and grey enhancement on the bitmap of the tire number; a step of positioning a tire number area; a step of binarizing an image of the tire number area; a step of eliminating the interference of an upper border and a lower border; a step of cutting a tire number character; and a step of performing normalization processing. The system comprises an image acquisition device, an image acquisition card and a computer, wherein the image acquisition device comprises a charge coupled device (CCD) camera, an auxiliary light source and a lens controller. The tire number on the lateral surface of an automobile tire can be intelligently, accurately and quickly identified, and the problem of the conventional technical scheme is solved.

Description

technical field [0001] The invention relates to the technical field of automatic identification, in particular to an identification method of an automobile tire number and an identification system for realizing the method. Background technique [0002] Since automobiles are high-speed traffic equipment, their safety is directly related to the personal and property safety of traffic participants. As an important part of automobiles, tires need better management and traceability of use and flow direction during production, storage, sales, use, and vehicle sales, so as to facilitate management and future after-sales service. At present, there are several schemes for the management of automobile tires: [0003] 1. Adopt barcode management: Barcode has many fragile physical characteristics. For example, with the long-term use of the car, the barcode will be damaged or fall off, or the barcode may be artificially replaced, etc., which will bring great harm to the after-sales serv...

Problems solved by technology

In warehouse management, manual checking of documents is required for inbound and outbound operations, which is labor-intensive

Moreover, because the data is very long and the number of products is large, it is easy for human eyes to misread or miss information when transcribing, to make mistakes when typing on the keyboard, or to complete manual transcription and manual keyboard input by different staff, which are prone to errors and cause input errors. Wrong tire number information, resulting in wrong tire number information management

Moreover, it is impossible to enter the information of millions of tires and related information into the database accurately every year by manual input, so each tire manufacturer does not have a database for each tire, which is not conducive to tire information query and scientific management.
