This dataset is divided into two part:

• Normal_Insulators contains the normal insulators capture by UAVs. The number of the normal insulator images is 600.

• Defective_Insulators contains the insulators with defect. The number of the defective insulator images is 248. Since we don't have too much defective insulators, the data augmentation method is applied. These images are synthesized by following process:

  • Use the algorithm in TVSeg to segment the defective insulator from a small part original images, the segment results are the mask images;
  • Use affine transform to augment the original images and their mask, the augmentation results is a lot of original-mask image pairs;
  • Use these image pairs to train the U-Net;
  • Use the trained U-Net to segment the rest part of images;
  • Attach the insulators in different backgrounds.

Both these two directories contain two subdirectories, one called images contains the image files, the other called labels contains the VOC2007 format annotations.

• The labels of Normal_Insulators contains only the annotations of insulators;
• The labels of Defective_Insulators contains not only the annotations of insulators but also the annotations of defects which on the insulators.

The images is provided by the State Grid Corporation of China, and the dataset is made by WANG Zi-Hao. If you have any question about this dataset, feel free to contact zhwang0721@gmail.com.
