We use industrial cameras to take images of steel wire ropes under different conditions. We put the images of steel wire ropes in five folders, named as：Camera position step up_1; Camera position step up_2; From dark to light; Rotate(360 degrees); Rotate(360 degrees). Images in different folders come from different sources, explained below: Camera position step up_1：Move the camera from bottom to top to obtain images of different positions of the wire rope.
