【摘要】：在如今科技高速发展的时代,人们不断追求智能化生活,图像处理和机器视觉技术的出现推动着人们追求的步伐。目前,虽然有些条码识别技术已经成熟,如采用图像和光电技术进行条码识别,但是这些传统技术不能满足一些大型智能化识别系统的功能需求。在这些大型系统中,不仅仅只需要对条码进行识别,还需要进行符号、文字、图形等信息识别。因此,在这种特殊环境下,功能复杂的条码定位及识别技术成为炙手可热的研究课题。本文以深圳友汇通有限公司所需求的电能表作为实例,对电能表条码识别系统进行研究与设计,主要内容如下:1、对电能表的条码识别及定位技术进行了算法研究与实现。采用模板匹配法、灰度水平投影、特征提取法和连通区域提取等方法对字符识别进行了研究与设计,能够实现字符的分割、定位和识别,对系统的识别率和智能化程度有很大的提高。在某些条形码污染严重而无法识别的情况下,通过字符识别得到条码信息就显得尤为重要。2、对电能表嵌入式智能条码识别系统进行了设计与实现。结合实际情况,采用VS2008软件对系统中智能算法和应用界面进行了模块化的程序设计,并开发了客户端软件,并进行了电能表条码识别系统的综合调试。。通过实验结论可以得出,本文的设计方案具有正确性与可行性,在电能表嵌入式智能条码识别系统中得到了很好的应用。此外,本文所提出的特殊环境中条码定位识别算法可以应用在某些图像识别技术研究领域,,具有较强的参考价值和实用价值。
[Abstract]:In the era of rapid development of science and technology, people continue to pursue intelligent life, image processing and machine vision technology promote the pace of people's pursuit. At present, although some bar code recognition technologies have been mature, such as image and photoelectric technology for bar code recognition, but these traditional technologies can not meet the functional requirements of some large intelligent recognition systems. In these large systems, not only bar code recognition, but also symbol, text, graphics and other information recognition are needed. Therefore, in this special environment, the complex bar code location and recognition technology has become a hot research topic. Taking the watt-hour meter required by Shenzhen Youhuitong Co., Ltd as an example, this paper studies and designs the bar code identification system of watt-hour meter. The main contents are as follows: 1. The algorithm research and implementation of the barcode identification and location technology of watt-hour meter is carried out. The method of template matching, gray level projection, feature extraction and connected region extraction are used to study and design the character recognition, which can realize character segmentation, location and recognition. The recognition rate and intelligent degree of the system are greatly improved. It is very important to get barcode information by character recognition when some bar codes are polluted and can not be recognized. 2. The embedded intelligent bar code recognition system for watt-hour meter is designed and implemented. Combined with the actual situation, the intelligent algorithm and application interface in the system are modularized by using VS2008 software, the client software is developed, and the comprehensive debugging of the bar code recognition system of watt-hour meter is carried out. The experimental results show that the design of this paper is correct and feasible and has been well applied in the embedded intelligent bar code recognition system of watt-hour meter. In addition, the bar code location recognition algorithm proposed in this paper can be applied to some research fields of image recognition technology, which has strong reference value and practical value.
