The Research And Embedded Realization Of Barcode Recognition System In Energy-meter

In today's era of rapid development of science and technology,people continue to pursue intelligent life,image processing and the emergence of machine vision technology to promote the pace of people's pursuit.At present,although some bar code recognition technology has matured,such as the use of image and optoelectronic technology for bar code recognition,but these traditional technology equipment can not meet some large-scale intelligent identification system functional requirements.In these large systems,not only need to identify the bar code,but also the need for symbols,text,graphics and other information to identify.Therefore,in this special environment,the function of the bar code positioning and identification technology has become a hot research topic.In this paper,Shenzhen Friends of Huitong Co.,Ltd.as the need for energy meter as an example,the energy meter bar code recognition system for research and design,the main contents are as follows:1,the energy meter bar code recognition and positioning technology for the algorithm research and implementation.The method of character recognition,gray level projection,feature extraction and connected region extraction is used to study and design the characters.It can realize the segmentation,location and recognition of characters.The recognition rate and intelligence degree of the system are great The improvement.In some bar code pollution is serious and can not identify the case,through the character recognition of bar code information is particularly important.2,the energy meter embedded intelligent bar code recognition system was designed and implemented.Combined with the actual situation,using VS2008 software on the system of intelligent algorithms and application interface for a modular design,and the development of the client software,and the energy meter bar code recognition system integrated debugging.Through the experimental conclusion,it can be concluded that the design scheme of this paper has the correctness and feasibility,and it has been applied well in the embedded intelligent bar code recognition system.In addition,the bar code location recognition algorithm proposed in this paper can be applied in some fields of image recognition technology,which has strong reference value and practical value.
