Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0023] refer to Figure 1 to Figure 5 , the vehicle feature point reconstruction system based on monochrome background one-dimensional target and structured light includes camera 1, base 2, connecting pipe 3, one-dimensional laser line projector 4, support rod 5, ring 6, one-dimensional target rod 7 , ball 8 and white cloth 9.

[0024] The base 2 is welded by a rectangular steel plate at the bottom, two vertical steel pipes and two V-shaped steel blocks at the top of the steel pipe. The rectangular steel plate is processed with a set of circular through holes. The camera 1 is placed on the top of the rectangular steel plate of the base 2. The white cloth 9 is Made of square white cloth, the top of the white cloth 9 is processed with a row of round holes, a group of rings 6 pass through the row of round holes at the top of the white cloth 9, the support rod 5 is a circ...

Abstract

The invention discloses an automobile characteristic point reconstruction system based on a single-color background one-dimensional target and structured light. With the system, camera calibration and automobile body characteristic point reconstruction can be realized synchronously by using a one-dimensional target and one-dimensional structured light. The automobile characteristic point reconstruction system is composed of a camera (1), a pedestal (2), a connecting pipe (3), a one-dimensional laser line projector (4), a support rod (5), a circular ring (6), a one-dimensional target rod (7), a ball (8) and a piece of white cloth (9). The white background of the system enables the image processing efficiency in calibration to be improved. The system has advantages of small occupied space, simple structure, high detection precision, simple and convenient operation, easy installation, low cost, and reliable performance.

Description

technical field [0001] The invention relates to a detection device in the field of automobile industry, more specifically, it relates to an automobile feature point reconstruction system based on a monochrome background one-dimensional target and structured light. Background technique [0002] The vehicle shape visual detection needs to extract the feature point position information of the car body, and fit the car shape surface according to the feature point position information. Usually, the background image of the car is relatively complex, which has a great impact on the extraction of body information. One-dimensional structured light can be used to identify the feature points of the car body, one-dimensional target can be used to calibrate the camera and provide a reference for the position of one-dimensional structured light in the world coordinate system, and a one-dimensional target with a monochromatic background is designed The car body feature point reconstructio...
