基于视频的二维条码识别算法研究-信号与信息处理专业论文.docx

万方数据 万方数据 西安理工大学硕士学位论文 This paper，using ordinary smart phone to collect videos and images of the QR code，on the basis of ta1∞g 由e VC6.0 as the development platform ，has conduct algorithm implementation and system development. In the experiment ，my paper made numbers of 20 different version video collected recognition tested ，wruch contain different editions and levels of eηor c心rrection grades. The exper凶lental result shows that eighty percent of the 企ame images could decode all corrected pointing at basis video-企equency band. Combining the voting algorithm，1 can make sure that 由e ent让ety discrimination of video-frequency band reach one hundred percents. It is thus clear that using the method of image discrimination can effective raise discrimination effect ofthe QR code.
