Paper Abstract

Optical position measuring methods can provide an effective tool for non-contact measurement of shape, deformation, movement and so forth. Many of them are based on the trianguration in the wide sense. In order to remove the correspondence problem in the triangulation, light beam projecting method has been used widely. In the light beam projecting method, surface of an object to be measured is swept by a bright spot and image positions of the bright spot are detected by the several mark position detecting apparatuses. Then the 3-D position of a bright spot is determined based on the principle of triangulation. In this method, the measuring accuracy of 3-D position is influenced considerably by the detecting accuracy of image position on the observation plane.
