The invention provides an automatic trajectory-tracking method based on round scanning laser, which comprises the following steps of: firstly projecting the round scanning laser onto the surface of an object to be measured, wherein the round scanning laser and a trajectory to be tracked have two or more than two intersection points, and one intersection point is superposed with the starting pointof the trajectory to be tracked; marking the starting point of the trajectory to be tracked as P0, and marking the last intersection point of the round scanning laser and the trajectory to be trackedas P1; then, enabling i=2; moving the circle center of the round scanning laser along the direction of straight line Pi-2Pi-1 for the distance of si, and marking the last intersection point of the round scanning laser and the trajectory to be tracked as Pi, wherein si is 1/Ni of the length of a line segment P0P1, and N belongs to [2,50]; and progressively increasing i one by one to realize automatic tracking.
