【摘要】 在应用中，与在线产品标识自动识别系统相类似的实例很多，对该系统的设计与开发的研究，具有较好的参考价值。本文针对在线产品标识自动识别系统的特点，对设计该系统中遇到的关键问题进行了实验研究和理论探讨，并根据研究结果解决实际应用中的相关问题。 首先，根据该系统运动成像的特点，对运动模糊复原的原理和方法进行了探讨，并进行实验和分析。 其次，本文对如何利用图像特征的分析来实现复杂大背景下小目标定位和提取进行了详细的探讨，分析了各种定位方法的适用性。 然后，本文对标识图像的几何校正和增强、标识中信息的提取、信息的特征抽取以及判决识别进行了介绍。 最后，针对具体应用对系统处理流程和结构进行设计，并对该系统的特点和适用性进行了分析。 在本课题中，作者所完成的工作有： 1．根据图像特征分析的原理，针对应用设计了结合图像纹理和形状特征分析的定位算法，实现了对在线产品标识自动识别系统中标识区域的定位和提取。 2．根据具体的要求，设计处理流程和系统结构，实现了在线产品标识自动识别系统，并结合实验结果分析了该系统的适用性和特点。更多还原

【Abstract】 This thesis focuses on the design of automatic identification system for the online products. Inspired by the theory and practice of automatic identification of plate license and classification letters, the author tries to explore the theory about identifying online products and carries out some specific researches.First of all, the author gives a general introduction to the image processing technique which is applied in this system, and analyses the features of it. Therefore, the author establishes the research focus of this thesis, and analyses the locating and selecting methods of small target in complex background.Then, the author explores the processing flow, and gives the practical algorithm to solve the designing difficulties in this system. The analysis of the experiment result is also carried out in this part to approve its stability and feasibility. The selection of marked information adjustment of marked images and identification of information features are also concerned here.Finally, the author offers a prospect of this field on the basis of the latest development in the world.Generally speaking, in this project, the task the author has completed including:1st. Based upon the theory of image features analysis, the author puts forward two kinds of target locating algorithm, and realizes the location of automatic identification system in the marked area.2nd. According to the specific requirements, the author provides the processing flow and concrete framework of the system, and has proved its feasibility and stability by the experiment results.更多还原
