Abstract

This invention relates to an apparatus and a method for automatically acquiring optimal stereo images for stereoscopic processing. The invention consists of a beam splitter 1, a mirror 2 mounted on a rotatable stage, shutters 6, 7 and a compensating zoom lens 9. These components are controlled by a processor and enclosed in a light-protective casing with means for attaching to a camera 4 or camera lenses. Stereo images are acquired by a pre-stereoscopic processing algorithm which controls the mirror in executing the correct vergence movement until maximally overlapped stereo images are obtained. Maximally overlapped stereo images are optimal for machine stereoscopic processing. The processor also controls the movement of the compensating zoom lens in conjunction with the vergence movement so that the two stereoscopic images are of the same optical magnification. With the incorporation of this compensating zoom lens, this invention permits the acquisition of stereo images for object to be positioned at a shorter distance than is possible otherwise. <IMAGE>
