摘要
边缘检测是图像边缘识别中的研究热点和难点,迄今已有许多边缘检测方法。文章研究了2种边缘检测算子——Sobel和Canny,并对实际的高压输电线图像进行了边缘检测。选取了2种不同天气条件下的图像进行了边缘检测,并比较分析了单一边缘检测处理的图像与经过中值滤波后的边缘检测处理的图片,以期得出质量较好的图像,为输电线路的准确识别和监测奠定良好的基础。
Although there are many edge detection methods,the edge detection has always been a research focus in practical application.By studing on two edge detection operators,Sobel and Canny,this paper discusses the edge detection on high voltage transmission line by choosing two images of different weather conditions.It compares the image processed only by edge detection with the one processed with median filter to get the better quality of image.The study lays a foundation for more accurate recognition and monitoring on transmission lines.
