摘　　要：文章提出了一种由彩色线扫描自动相机、高速图像获取卡、计算机和喷气头等组成的机器视觉系统。它可以在线自动识别和去除羊毛中的污物。文章对其中的3个关键技术——图像采集系统、图像处理算法和机械电子反馈控制系统进行了较详细的描述。在实验的基础上分析了这种机器视觉系统的性能和识别精度,并提出了下一步的研究计划。A machine vision system, consisting of a colour line-scan CCD camera, frame grabber, host computer and air-jets, is presented in this paper, which can be used to identify and remove the contaminants in scoured wool. As the key techniques, the image acquisition system, the algorithm based on the features of the contaminant colour and shape, which can detect contaminants with white and light colour in white background wool, and the mechatronic sorting system are described in detail. Finallythe performance of the machine vision system is.tested and further research work is discussed.
