绝缘子作为输电线路中用量庞大的部件，其状态对输电线路的稳定运行至关重要。针对现场红外图像中绝缘子的识别问题，设计了一种高斯尺度空间 GHT 方法，基于此，提出了一种基于高斯尺度空间 GHT 的绝缘子红外图像的识别方法。首先利用形态学方法滤除图像中的小块和噪音，基于Canny检测算子提取图像边缘；然后对模板进行高斯尺度空间分解，将分解结果和输入图像进行基于GHT 的模板匹配；最后结合绝缘子的形状特征值识别出绝缘子。实验结果表明该方法可以准确地识别出绝缘子，并为后期绝缘子的故障诊断提供依据。

The status of insulator is important for the stable operation of the transmission line as the number of insulator is large. Aiming at the recognition problem of insulator in the infrared image on site, a method of Gaussian scale-space and GHT was designed, and then a kind of method about insulator's recognition in infrared images based on Gaussian scale-space and GHT was put forward. Firstly, small pieces and noises in images were filtered based on morphological method, and then the edge of image was extracted based on Canny detection operator. Secondly, the Gaussian scale-space of template and the input image were matched based on GHT. Finally insulator was identified according to the characteristic value of the shape of the insulator. The experimental results show that the method can identify the insulator accurately and provide the basis for fault diagnosis of insulator.
