Universal type centering one-dimensional calibration target of automobile-morphology visual detection system

The invention discloses a universal type centering one-dimensional calibration target of an automobile-morphology visual detection system, and aims to solve the problem of centering rotation required by calibration of one-dimensional calibration target of the automobile-morphology visual detection system. The universal type centering one-dimensional calibration target of the automobile-morphology visual detection system is mainly composed of a video camera tripod (1), a video camera (2), characteristic point identifiers (3), a one-dimensional calibration target bar (4), a universal joint (5) and a cross square steel (6); and the one-dimensional calibration target bar (4) can selectively reach any position around the center of the universal joint (5), the system acquires images of the characteristic point identifiers (3) through the video camera, and all parameters of the video camera are calibrated according to the images, acquired by the video camera, of the characteristic point identifiers (3) at the multiple positions. The system provides the universal type centering one-dimensional calibration target, which has the advantages of simple structure, high detection precision, easy and simple operation, easy installation, low cost and reliable performance, of the automobile-morphology visual detection system.
