Terahertz-based rail surface damage detection method and system and storage medium

The invention discloses a rail surface damage detection method and system based on terahertz and a storage medium, and can be applied to the technical field of workpiece damage detection. The method comprises the following steps: acquiring rail point number characteristic data acquired by a network port camera; performing point cloud segmentation on the rail point feature data to obtain rail dominant point cloud feature data and point cloud feature data needing to be reconstructed; and carrying out rail surface damage detection according to the rail dominant point cloud feature data and the point cloud feature data needing to be reconstructed. According to the method, after the rail point number feature data collected by the network port camera is segmented, rail surface damage detection is performed according to the rail dominant point cloud feature data obtained through segmentation and the point cloud feature data needing to be reconstructed, so that contact-type equipment is not needed to enter and exit i
