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.
