Paper Abstract

In order to meet the progressively demand of measuring large size part in industrial applications, a precise and rather fast 3-D measuring system is developed by utilizing coded grid points. The LCD projection projects two groups of fringe sequences perpendicular to each other controlled by computer and form target points with the only code, these coded points as the target points on object surface. After matching process in the computer, the coded points' coordinates could be worked out according to stereo vision principle. In this paper, a kind of grid cross point's division, coding and matching method has been proposed, and at the same time, the centric of the coded points has been calculated. The above steps support the necessary condition for the coded points' coordinates calculation.
