The invention discloses a steel rail crawling detection system and method based on stereoscopic vision, the system comprises a small rail car and an observation pile, and the small rail car carries a laser sensor, a binocular camera and a main control device; the observation pile is mounted at a preset position on the outer side of the steel rail as a reference; a mark point is arranged on the observation pile; wherein the laser sensor detects the end position of the marker line on the steel rail; the binocular camera collects a mark point image on the observation pile and sends the mark point image to the main control device; a stereoscopic vision measurement module is loaded in the main control device, spatial position information of the steel rail relative to the observation piles is obtained through calculation based on a binocular vision measurement method, and steel rail creeping amount information is obtained by measuring the spatial position information of the same observation pile for two adjacent times. The steel rail creeping displacement is automatically measured through the small rail car and the stereoscopic vision technology, movable detection can be carried out, rapid and accurate measurement can be conveniently carried out on whole-road large-range steel rail creeping, errors are reduced, and meanwhile safety risks are reduced.
