随着时代的发展,科学研究、医疗卫生、公共安全和工农业生产等领域对数字图像采集和处理的应用越来越广泛,本文提出了一种基于USB2.0接口图像采集及处理系统的设计方案.该系统的数据采集源为图像传感器,包含数据传输,实时显示和角点提取三个模块.在角点提取过程中,对Harris算子的检测原理、实现方法及性能分析分别进行了说明.最终使用MATLAB编程工具,完成对不同图像的Harris角点检测.根据检测结果可以看出,使用Harris角点检测方法,检测速度快,得到的角点较均匀,算法稳定,对数字图像的处理有着重要的现实意义和应用价值.

With the development of the times,the acquisition and processing of digital image are getting wided used in fields such as scientific research,industrial and agricultural production,medical and health services,public security and so on.The article introduce a schematic of the data acquisition and processing system based on USB2.0.The system takes area of image sensor as data source and consists of data transferring module,real-time displaying module,corner detecting module.In the process of corner detection,the elements,the methods and the capability of Harris operator are analyzed and contrasted,then using MATLAB to complete different images' Harris corner detection.The detection results showed that the speed of Harris corner detection method was fast and this method can get even corners.So this algorithm was stable.Therefore,the research on image detection system is very important and has great value.
