Abstract

The invention discloses a shaft end grounding binocular reconstruction system and method for concentric quadratic curve epipolar geometry, and aims to solve the problem of shaft end grounding binocular detection for concentric quadratic curve epipolar geometry. The concentric quadratic curve epipolar geometry shaft end grounding binocular reconstruction system is mainly composed of a base (1), a supporting rod (2), a laser connecting rod (3), a left camera (4), a laser (5), a right camera (6), a camera connecting block (7), a target plate (8), a linear sliding table (9), a connecting rod (11),a supporting rod fixing block (12), a connecting rod fixing block (13) and a laser fixing block (14). The target plate (8) is a flat plate of which the surface is pasted with a concentric quadratic curve; the supporting rod fixing block (12) is a cuboid iron block, two circular through holes with the axes perpendicular to each other are machined in a surface of the supporting rod fixing block (12), and threaded holes are machined in two ends of the supporting rod fixing block (12) respectively. The concentric quadratic curve epipolar geometry shaft end grounding binocular reconstruction system and method are simple in structure and reliable in performance.

Description

technical field [0001] The invention relates to a measuring device and a measuring method in the field of rail vehicles, and more specifically, it is a system and method for grounding a shaft-end binocular reconstruction of a concentric quadratic epipolar geometry. Background technique [0002] As the speed of high-speed EMUs continues to increase, the performance requirements for each component of high-speed EMUs are also getting higher and higher. The increase of vehicle speed increases the friction between the contact plate of the grounding device of the axle end of the bogie axle and the carbon brush, which poses a very serious threat to the operation safety of the rail vehicle. Commonly used contact disk measurement systems are mainly contact measurement systems. However, the contact measurement system is easy to scratch the measured object because the measuring instrument needs to be in contact with the surface of the measured object, and the measurement speed is very...
