Embodiment Construction

[0020] The identification information of different magnetic hard disks will be different to a certain extent, but generally include serial number (SN), model number (MODEL), etc., as shown in Figure 1 below, the identification information of three brands of magnetic hard disks: Seagate, Western Digital, and Maxtor Infographics.

[0021] The serial number (SN code) is the factory serial number set for each magnetic hard disk, and it is the "ID card number" of the magnetic hard disk. Regardless of whether it is a magnetic hard disk of different brands or a magnetic hard disk of the same brand but with different capacities, the serial number (hereinafter collectively referred to as the SN code) is unique. As shown in Figure 2, (a) and (b) are both Seagate hard drives, with the same model number (MODEL code) and different SN codes. The SN code of the magnetic hard disk is composed of Arabic numerals and English letters, and they are all regular printed characters, so the identifi...

Abstract

The invention discloses a magnetic hard disk sequence code recognition method based on machine vision. The method comprises the steps that step 1, preprocessing a magnetic hard disk sequence code picture; step 2, carrying out character segmentation of a sequence code, and carrying out HOG feature extraction on segmented characters; and 3, constructing an identification model by adopting a supportvector machine (SVM) algorithm, and identifying the magnetic hard disk sequence code picture.

Description

technical field [0001] The invention belongs to the technical field of magnetic hard disks, and in particular relates to a machine vision-based recognition method for serial codes of magnetic hard disks. Background technique [0002] Magnetic hard disk is an important information storage medium for computers. The brands mainly include Western Digital (WD), Seagate (ST), Maxtor (Maxtor), etc., and the capacity has developed from the initial GB level to the current T level. Magnetic hard disk recording and transmission of information has the characteristics of high efficiency, stability and convenience, which also causes users to face security issues such as illegal theft, copying, and use of private information in the hard disk. For this reason, degaussing treatment is often used to destroy information on waste magnetic hard disks. At present, commercial degaussing equipment has been put into use in the market, such as Xinanbao XBC series degaussing machine, FD series degaus...
