Aristotle observes partial solar eclipse by seeing image of the sun projected through small spaces between the leaves of a tree. Over the centuries, this optical phenomenon leads to development of the camera.
Machine Vision Industrial Camera Revolution
Machine vision technology has revolutionized manufacturing and industry. Today's industrial cameras and imaging systems allow us to see and record images in ways that the ancient visionaries and early developers of image capturing devices could not have imagined.
Machine vision technology has evolved from discoveries made in optics, chemistry, physics, electronics, television, mechanical design, mathematics, software, artificial intelligence, computers and computer vision, and the internet, just to name a few. As certain milestones were met in these various disciplines, they paved the way for imaging systems to be developed for automatic inspection, measurement, process control, and robot guided applications.
This interactive timeline presents some of the key people and events that made it all possible.
500BC - 1700's
Development of the pin-hole camera obscura, initially used to reproduce images to aid in drawing and painting.
Daguerreotype camera, named after its French inventor Louis Daguerre, is first photographic camera developed for commercial manufacture.
Russian scientist and inventor Boris Rosing develops electronic scanning methods of reproducing images.
Kinescope, invented by Russian scientist Vladimir Zworkin, who worked with Rosing, is first practical electronic system for the transmission and reception of images.
RCA and Albert Rose et. al. introduce Image Orthicon tube, winning production contract from US Navy in 1944; it became common video tube in American Broadcasting from 1946-68.
RCA and P. K. Weimer, S. V. Forgue and R. R. Goodrich introduce Vidicon tube, a video camera tube design in which the target material is a photoconductor. Prior to the late 1970s, NASA used Vidicon cameras on most of their unmanned deep space probes equipped with the remote sensing ability.
To offer more image stability and to compete with RCA, Philips introduces the Plumbicon, Hitachi the Saticon (along with Sony and Thomson), and Sony the Trinicon, which Sony also used in some moderate cost professional cameras in the 1980s, such as the DXC-1800 and BVP-1 models.
Larry Roberts, accepted as the 'father of computer vision,' discusses the possibilities of extracting 3D geometrical information from 2D perspective views of blocks (polyhedra) in his MIT PhD thesis.
T.S. Huang 'Computer Vision: Evolution and Promise', University of Illinois at Urbana-Champaign, Abstract
Frank Wanlass, American electrical engineer patents CMOS (complementary metal-oxide-semiconductor) logic circuits used in digital logic circuits as well as analog circuits like CMOS image sensors.
CCD, or charged-couple device is invented at American Bell Laboratories by William Boyle and George E. Smith, allowing for the transfer of a charge along the surface of a semiconductor from one storage capacitor to the next - a major contribution to digital imaging.
Michael Tompsett, British-born physicist who worked at American Bell Laboratories, designed and built the first ever video camera with a solid-state (CCD) sensor, for which he received a patent in 1972.
William K Pratt and Harry C Andrews found the USC Signal and Image Processing Institute (SIPI), one of first in world dedicated to image processing.
Bryce Bayer, an American scientist working for Kodak, brought vivid color image capture to digital photography with the invention of his Bayer filter.
Smart cameras for industrial applications are introduced, based on optical mouse (first imaging device and embedded processing unit in a compact system) developed by Richard Lyons at Xerox in 1981
