The invention provides a detection device for track smoothness, and belongs to the technical field of track smoothness detection. The detection device for track smoothness comprises a track car which stretches across a track and can move forward and backward along the extending direction of the track, a measuring target which is arranged on the track car in a bearing mode, a computing device and a laser emitting device which is positioned on the track in front of the measuring target, wherein the measuring target comprises a target surface, and a camera which is positioned at the back of the target surface and is fixed at the opposite position of the target surface; the target surface is made of a semitransparent material, the laser emitting device is used for projecting laser onto the target surface to form a light spot, and the camera is used for capturing a light spot image formed by the light spot on the target surface; the computing device is connected with the camera, and is used for receiving and analyzing the light spot image and obtaining the position of the light spot.
