The invention discloses a detection system for extracting a steel rail contour curve through infrared laser irradiation. The detection system comprises a hardware module and a software module. The hardware module comprises a PC and a laser contour sensor composed of a CCD camera, 650nm infrared laser and an embedded mainboard of an ARM-v7 chip. The PC is connected with the laser contour sensor. The software module comprises a USB communication module driver, a command sending module, a data receiving and storing module and a data reading and model establishing module; the invention further discloses a detection method for extracting the steel rail contour curve through infrared laser irradiation. The hardware module scans a steel rail contour to obtain initial contour data; the software module processes and visualizes the contour data obtained by the PC; the system has the advantages that the system is low in cost, simple in structure and high in universality, the system can be directly used for detection and can also be used as vehicle-mounted detection systems and handheld detection systems, and the system is easy to maintain and can be developed again.
