Abstract

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.

Description

technical field [0001] The invention relates to an inspection device in the field of automobile industry, more specifically, it relates to a dynamic automobile body shape reconstruction system based on surface structured light active vision. Background technique [0002] In order to ensure the safe driving of the car, it is one of the main inspection items in the field of automobile inspection to detect the overload and size modification of the automobile reasonably and quickly, and to measure the shape and size of the automobile body. At present, the measurement of vehicle size is mainly based on manual meter measurement, which has low efficiency, poor accuracy, and high labor intensity for staff. The method of scanning the car body with a laser plane and collecting the car image through the camera to realize the measurement of the shape and size of the whole vehicle is expected to solve the above technical bottlenecks due to its characteristics of fast, accurate and high r...
