Abstract A set of surface defect inspection system for hot heavy rail was designed, and the character of radiation in high temperature for hot heavy rail was analyzed. As for hardware of the system, six linear CCDs have been adopted to shoot the heavy rail from multi-angle, so that the various surface images could be attained, and multi-channel of images were transmitted to image processing workstation in real time. On this basis, frequent defect for hot heavy rail was presented, the key technique for hot heavy rail was studied, and distinguishing and locating the defect was realized.
