Abstract

A new geometry for the acquisition of three-dimensional coordinates of points on the surfaces of objects is described. It is based on the use of a pattern projected onto the scene and a mask in the aperture of an objective lens. A compact charge-coupled-device camera is used to make the three-dimensional measurements. Experimental results are presented.
