Problems solved by technology

[0004] Aiming at the current situation that it is impossible to verify the measurement results of objects in general positions and attitudes in space by machine vision measurement systems, the present invention provides a method that uses three-way linear guide rails and two-direction arc guide rails to make reference targets reach the space. Any position and angle, simple structure, high verification accuracy, small cumulative error, complete functions, easy operation, high verification efficiency, easy installation, strong versatility, and reliable performance can meet the requirements of national metrology and quality supervision departments and machine vision system manufacturers. General position and attitude measurement benchmarks in space required for machine vision measurement system verification

Embodiment Construction

[0066] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0067] refer to Figure 1 to Figure 18 , the general position and attitude measurement datum of the machine vision measurement system space is composed of the position adjustment part A and the attitude adjustment part B. The position adjustment part A completes the adjustment of the spatial position, and the posture adjustment part B completes the adjustment of the spatial angle.

[0068] The position adjustment part A includes a bottom plate 1, a longitudinal guide rail 2, a slider 3, a transverse connecting plate 4, a transverse guide rail 5, a cable mounting plate 6, a sensor 7, a sensor mounting frame 8, a sleeve 9, and a vertical base 10 , connecting plate 11, leading screw 12, guide post 13, end cover 14, hand wheel 15, backguy mount 18, L-shaped plate 35, upper bearing 44 and lower bearing 45.

[0069] The bottom plate 1 is a rectangular steel plate, and the ...

Abstract

The invention discloses a space general position and orientation measurement standard of a machine vision measurement system, and aims to solve the problem that verification on measuring results of objects in general positions and orientations in space of the machine vision measurement system cannot be realized. A three-way linear guide rail and a two-way curved guide rail are utilized to enable a standard target to reach optional position angles in the space. The system has the advantages of simple structure, high accuracy in measurement, small accumulative errors, completeness in functions, convenience in operating and the like. The system comprises a position adjusting part (A) and an orientation adjusting part (B). By the aid of the space general position and orientation measurement standard, the verification on space general position and orientation measuring results of the machine vision measurement system is realized.

Description

technical field [0001] The invention relates to an inspection device of a measuring instrument in the field of machine vision measurement, more specifically, it relates to a general position and attitude measurement standard in the space of a machine vision measurement system. Background technique [0002] Machine vision inspection is one of the important research contents of the instrument discipline. Its research significance is to seek a non-contact, automatic, high-precision rapid measurement method for the measurement of mechanical parts, automobiles, aerospace, ships and other application fields. The research provides sufficient advanced technology guarantee and theoretical support to achieve the purpose of non-contact automatic measurement. [0003] The accuracy of the measurement results of the machine vision measurement system is the core factor that determines the effectiveness of the measurement. Whether the measurement results can truly reflect the real size of t...
