摘　　要：绝缘子是输电线路上的重要设备,其运行状况直接影响到电网的安全运行,对绝缘子表面状态的监测是十分重要且必要的。本文提出一种基于航拍可见光图像的绝缘子表面状态检测方法,通过建立模糊综合评判数学模型,确定绝缘子的污秽程度和表面是否有裂纹,将来可以应用于对航拍图像的分析。Insulators are important equipments on transmission line.The operation condition of insulator has direct effect on the safe running of the power network, so it＇s very important and necessary to inspect its surface state.ln this paper, a method baced on aerial images to detect the surface state of insulators is put forward. By establishing a mathematics model based on fuzzy comprehensive judgment, the method can be used to estimate the dirty state of insulator and whether there is a crack on the surface. The images screened on the helicopter can be analyzed by this way in the future.
