Metallic Surface Defect Datasets

Casting Billet: This dataset comprises 1,060 images with resolutions ranging from 96\u00d7106 to 3,228\u00d7492, depicting high-temperature continuous casting billets. The images were acquired using an advanced optical inspection system comprising two 4096-pixel line-scan CCD cameras equipped with blue laser line illumination, achieving a spatial resolution of 0.18 mm\/pixel. Among these, 780 images contain surface defects, categorized into six types: scratch (Sc), weld slag (WS), cutting opening (CO), water slag mark (WSM), slag skin (SS), and longitudinal crack (LC).Steel Pipe: This dataset consists of 1,227 images of steel pipe surfaces with a fixed resolution of 728\u00d7544. Image acquisition was performed using a DALSA surface array monochrome camera, which achieves a spatial resolution of 0.2 mm\/pixel and a maximum frame rate of 308 fps. Among these images, 554 contain defects, which are divided into four types: warp, external fold, wrinkle, and scratch.
