摘要： A method for measuring the contours (30) of a three-dimensional object (4); and a method for calibrating an optical system (2, 8). The object (4) is placed into the field of view of the optical system (2, 8). The optical system (2, 8) is activated to obtain a set of data giving a phase (x.sub.t) at each of a plurality of pixels corresponding to the object (4). The phases (x.sub.t) are unwrapped, e.g., by a method of ordered phase unwrapping. The unwrapped phases are converted into a set of three-dimensional coordinates (x.sub.s, y.sub.s, z.sub.s) of the object (4) for each of the pixels. These coordinates (x.sub.s, y.sub.s, z.sub.s) can be portrayed on a display of a computer (10). The method for calibrating the optical system (2, 8) shares several common steps with the above method. In addition, coordinates of a test calibration fixture (38, 46) are first mechanically measured. Following optical measurement of the calibration fixture (38, 46), an optimization procedure is used to minimize the difference between the mechanically measured coordinates (x.sub.m, y.sub.m, z.sub.m) and the coordinates (x.sub.s, y.sub.s, z.sub.s) calculated from the optical measurements. The optimization procedure in the calibration method fixes the intrinsic and extrinsic parameters of the optical system (2, 8). A blending method can be used to increase the dynamic range of the measured intensity. Phase shifting is performed by either a method of temporal phase shifting or a method of spatial phase shifting.

摘要： An optical system provides for receiving and transferring an image in three dimensions. The system includes at least two non-reflecting first receiving mirrors being disposed in a V-shaped configuration which allows the free pass of an image and this image is captured and directly projected toward a common plane. A mirror for each non-reflecting mirror, which are symmetrically disposed behind each non-reflecting mirror also captures the image and this is reflected with a predetermined incidence angle over the rear part of the non-reflecting mirrors. The image reflected over the rear part of the non-reflecting mirrors is projected toward coincidence with the rays captured by the non-reflecting mirrors producing an image with a three dimensions effect.

摘要： A three-dimensional television camera system based on a spatial depth signal and receiver system therefor is disclosed wherein a video depth signal is generated in spatial synchronization with the raster scan of a TV camera viewing a scene. The video depth signal is generated by taking the ratio of the outputs of a pair of spaced apart sensors receiving a reflected laser beam of a laser projector situated between the sensors. The laser projector, sensors, and TV camera are in close proximity to each other. A portion of the energy receiving photocell of each sensor is blocked by a parallax barrier so that a proportion of the reflected laser beam energy is detected and that receipt of energy is angle dependent. By such construction, the depth difference of two points proximate each other is sensed. A continuous video depth signal is outputted in synchrony with the TV camera video signal to the receiver system. The described receiver system employs two TV cathode ray tubes to be viewed stereoscopically, i.e., one for each eye. On CRT operates as in a convention television receiver receiving the TV camera video signal and the other CRT receives the same video signal except the horizontal sweep component is modified by the video depth signal. By such instrumentality, a scene is viewed in three dimensions much like the sell known stereoscope.

摘要： A method and apparatus for automatically determining pathway boundaries for autonomous robotic navigation. A structured light pattern consisting of a plurality of lines is projected on the pathway and background and the reflected pattern is detected by a stereoscopically located video camera. Since the texture of the pathway and background are different, the captured image may be processed to distinguish one from the other. Image processing includes Hough transformation of the image field, rank filtering and morphological dilation. The end points of the pathway lines identified by such processing as well as the 3-D coordinates of such end points are determined.

摘要： The detector includes a focusing lens for focusing pulsed laser light reflected from an object onto a fiber optic array. The fiber optic array is configured to receive a two-dimensional image from the focusing lens and to convert the two-dimensional image into a line image. A streak camera responsive to light from the fiber optic array provides time resolution for the light from each of the fibers in the array. A two-dimensional detector records the light output from the streak camera and electronics store data and process information to construct three-dimensional images.

摘要： A method and apparatus are disclosed for real-time optical broadband pseudocolor encoding of an image. A light polarization spatial modulator is utilized to density encode an incident beam of plane-polarized light; the beam is dispersed into its primary colors; the polarizations of the dispersed beams are analyzed to produce positive, negative, and bidirectionally modualated images which are each separately encoded with a primary color; and the primary-color encoded beams are combined to produce a pseudocolored image. In a preferred embodiment the pseudocolor encoding apparatus comprises a compact white-light projection system and a liquid-crystal television spatial light polarization modulator. The invention makes possible the large-screen display of broadband pseudocolor images from real-world input scenes from a television camera.
