Design of QR code recognition system based on SoPC
摘要
Abstract
This paper introduces a QR code recognition system based on SoPC , whose purpose is to provide a kind of fast , low-cost , and interfaces-flexibled QR code reading scheme for handheld and embedded devices . The system consists of the image grabbing module , image preprocessing module , QR code decoding and error-correcting module , and peripheral interfaces module . Image grabbing module drives the CMOS camera to get the QR code image , with the image preprocessing module then preprocesses the image to facilitate decode , and the QR code decoding and error-correcting module realizes the code correcting and decoding towards QR code data .关键词
