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...

Examples

Embodiment Construction

[0051] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0052] refer to Figure 1 to Figure 21 , the dynamic car body shape reconstruction system based on surface structured light active vision includes a base 1, a linear guide rod 2, a screw 3, a slide table 4, a bracket 5, an angle steel 6, a linear guide rod fixing seat 7, and a stepping motor 8. Bearing support plate 9, camera 10, lead screw nut 11, linear bearing 12, bearing cover 13, wire feeder fixing seat 14, wire feeder 15, coupling 16, proximity switch fixed support plate 17, right proximity switch 18. Left proximity switch 19, computer 20, IO card 21, switching power supply 22, stepper motor driver 23, left relay 24 and right relay 25.

[0053] The base 1 is formed by vertical welding of two short rectangular steel plates at the two ends of a slender rectangular steel plate, placed on a flat ground, and a bearing support plate 9 is vertically welded on one side ...
