摘　　要：介绍了一种基于计算机视觉烟叶自动分级系统的硬件组成,该系统由输送装置、称重系统、视觉系统、均匀照明室4部分组成。输送装置可将烟叶打散摊平,使烟叶保持一定的厚度呈现给CCD摄像头;称重系统采用电子皮带秤完成烟叶的在线实时称重,并将数据发送至计算机内存;视觉系统同时监视、采集烟叶图像信息送至计算机内存进行处理;照明系统为CCD摄像头均匀、恒定的光源,保证图像的清晰。实验证明了系统的可行性,其辅助机构与烟叶实时分级决策算法尚待进一步的研究。A tobacco automatic-graduation experimental system hardware composition based on computer vision is introduced. The system for tobacco image acquisition and processing includes a single-lane conveyer, weighing system, vision system and an illumination chamber. The conveyer is used for handling and breaking up the tobacco leaves to the CCD cameras. The weighing system is used for weighting the tobacco, and sending the data to computer memory. The vision system is used for monitoring and collecting images of tobacco,and processing it in computer memory. The illumination chamber is used for providing uniformity and invariable illumination, and ensuring the image in focus. The preparatory examination results validate the feasibility of system, the assistant system and tobacco real time grading and decision-making algorithm will be developed in the subsequent research.
