摘　　要：电力系统的"遥视"功能可以监视变电站的设备运行情况,并将采集到的图像传输到终端。在对设备图像进行分析的过程中,正确提取出分析目标可以大大提高图像处理速度。分别提出了基于灰度特征和颜色特征对绝缘子图像进行目标提取的方法。前者步骤复杂,但受运行时间限制小;后者简单易行,但因涉及颜色特征,仅对运行时间短的绝缘子提取效果明显。Equipments in substation can be monitored by remote Video system, and the images are transferred to the terminal at the same time. Extract the correct analysis of target can greatly improve the image processing speed, during the process of image analysis equipment. In this paper, extract target in insulator-images methods are separately proposed based on gray-character and color-character. The former has complex step but the influence made by running time is little. The latter is feasible while it is only effective to the short-running time insulator because of the color character.
