Abstract The identification and location of the target with a complicated background is a very hot and difficult issue in the field of pattern recognition. In the complicated background, to identify the insulator string from aerial image used for inspection of grid, a new insulators image identification and location algorithm based on frequency-tuned is proposed. First of all, the inspection image containing the insulators is transformed from RGB color space into HSV color space, threshold segmentation is carried on H, S and V component spaces. Then, by using the low frequency and high frequency information, the significant information of the insulators contained in H, S and V images is computed by the frequency-tuned method. Meanwhile, the primary insulator image is obtained by fusing the saliency information of insulators. Finally, the segmented insulators are obtained by applying Otsu algorithm and opening operation to the significant images, and we locate the insulators by using contour recognition. The experimental results show that the method can accurately identify the insulator string from aerial image with complicated background, which has a high value for engineering application.
