Abstract

Disclosed is a system for perceiving the third dimension in scene analysis, using bidimensional images acquired by TV cameras. The system includes a TV camera with a stereo divider mounted on its lens, and a computer, equipped with a frame grabber card. The system allows acquiring and processing single stereo-bipartite images, by which three- dimensional (3-D) data of the objects and their motion in the space can be detected and measured. Many robotic applications can take advantage of such a system. (Image Omitted)

Single Camera Stereoscopic Vision System

       Disclosed is a system for perceiving the third dimension
in scene analysis, using bidimensional images acquired by TV cameras.
The system includes a TV camera with a stereo divider mounted on its
lens, and a computer, equipped with a frame grabber card. The system
allows acquiring and processing single stereo-bipartite images, by
which three- dimensional (3-D) data of the objects and their motion
in the space can be detected and measured. Many robotic applications
can take advantage of such a system.

      3-D vision systems are often used in robotic applications. In
case of robotic arms equipped with "eye-in-hand" devices, the spatial
occupancy of the acquisition arrangement is also crucial. Compactness
is an important requirement since a more free movement is allowed to
the arm, with less collision probability and minimum influence on its
dynamic behavior.

      A considerable problem arises in dynamic scene analysis, where
motion is a major concern, regarding either some objects in the scene
or the vision device itself. In this case, the acquisition of the
stereo pair of images must be contemporaneous.

      The system shown in the figure includes the following
components:
  1. a single camera equipped with a wide-angle lens
  2. an optical stereo-divider [*]
  3. a computer equipped with a frame grabber card
  4. software (SW) fo...
