Abstract
An optical camera three-dimensional coordinate measuring system for use with objects to be measured is described. The system may include a compact, easily moveable, and rotatable, target of known dimensions comprising a spherical surface to be placed in contact with the object to be measured at different points along the object to be measured thereby eliminating the necessity of using a larger extended probe contact tip extending from the target to the object to be measured. At least one or more light emitting source may be located in a known position in the target such as the center of the spherical surface for example. At least two cameras located at different and known coordinate locations for receiving light from the light emitting source from different optical perspectives may be included. The position in three dimensional coordinates of the object to be measured is computed from the images taken by the cameras.
