The invention discloses a surface structured light active vision based dynamic automobile body morphology reconstruction system which aims at solving the problem that the automobile morphology active vision measurement on automobiles cannot be achieved through the surface structured light in the stationary state. The surface structured light active vision based dynamic automobile body morphology reconstruction system is mainly formed by a base (1), a lead screw (3), a stepper motor (8), a camera (10), a line projection instrument (15), a right proximity switch (18), a left proximity switch (19), a computer (20), an IO card (21), a switch power supply (22), a stepper motor driver (23), a left relay (24), a right relay (25) and the like. The surface structured light active vision based dynamic automobile body morphology reconstruction system is smooth in scanning, simple in structure, high in detection accuracy, convenient to operate, easy to install, low in cost and reliable in performance.
