A system for dynamic and multi-object com variety identification was developed based on the technology of computer vision. The hardware device was made up of 3CCD colorful camera, image gathering card, photoelectric switch, conveyer belt and light sources box. TV software was made up of image gathering, image processing, feature extraction, pattern recognition and feature database functional module, which was compiled by Visual C+ + 6.0 and Access 2007. Four representational southwest hybrid com varieties were identified by the system. The results showed that the maximal discriminating rate of the system was 95% and the shortest discriminating time was 5.4s, and the system could realize the dynamic, rapid and multi-object com variety idenlificalion.%研制了一种基于计算机视觉技术的动态多对象玉米品种识别系统,设计选用3CCD彩色摄像头、图像采集卡、光电开关、输送带、照明箱等零部件组成硬件装置 利用Visual C++6.0、Access 2007软件,编制图像采集、图像处理、特征提取、模式识别、特征库等功能模块程序,构成软件部分.系统对4种具有代表性的西南地区杂交玉米进行了品种识别,结果表明,最高识别率可达95％,最短识别时间为5.4s.动态多对象玉米品种快速识别系统可实现多粒玉米种子的动态、快速、准确识别.
