Non-contact image measuring system

摘要: The invention discloses a non-contact image measuring system, which comprises worktable, three-dimensionally movable camera, laser displacement sensor and triaxial grating bar data acquisition card, wherein the camera are connected with Z-axis guide rail via connection beam vertically correspond to worktable; servo motor can drive slide block move so as enable up down. acquires images in XY plane for survey, height of each positioning point near measured pixel is Z direction work out average value, distance needing be moved when being focused determined according system simply quickly detect complex workpieces, increases measurement efficiency, expands scope meets requirements on images.
