The invention provides a system and a method for detecting the smoothness of a track and belongs to the technical field of track detection. The system for detecting the smoothness of the track comprises a laser emitter, a target, image pick-up equipment and data processing equipment, wherein the target surface of the target is made from a semi-transparent material; the laser emitter is positioned in front of the target; the image pick-up equipment is positioned behind the target, and the central horizontal line of a camera of the image pick-up equipment directly faces the center of the target surface of the target; the camera of the image pick-up equipment is used for capturing a light spot image, formed on the target surface of the target, of the laser light of the laser emitter; the data processing equipment is connected with the image pick-up equipment and is used for acquiring the light spot image and processing the light spot image to obtain the position of a light spot. According to the system and the method, the technical problems of high detection error of the light spot, injury to the eyes of a person and the like in the prior art are solved.
