摘要： This invention relates to a method and apparatus for sensing a three-dimensional (depth and illuminance) image of a scene. It is based on the inverse-square law relating the incident brightness on an area illuminated by a light point source, to its distance from the point source. In the preferred embodiment of the invention the scene is sequentially illuminated by more than one light point source each at a pre calibrated location in the reference coordinate system. The resulting reflections from the field of-view are sensed by a stationary digital camera that maps each scene element into a corresponding image pixel, to provide a 2-dimensional brightness map that contains the photometric values of each image pixel for each specific illumination. Each pixel photometric value depends on the illumination incident on the corresponding scene element which, in itself, is further determined by the element inherent Lambertian reflectance-coefficient at the illumination wavelength, the element orientation relative to the coordinate system, and the element illuminance as determined by the point source brightness and the distance separating the point source and the scene element. Each brightness map is different from its sequel due to the differing point-source locations. By manipulating the brightness maps the spatial location of each scene element relative to the fixed point sources is determined, thus yielding a depth-image as well as a brightness-image.

摘要： Disclosed is a system and a method for compressing digitized color video data by generating codes into a pattern of tables for regions in frames of the video data exhibiting certain patterns. An image frame in a video data stream has a plurality of pixels assigned digitized color and luminance data. The image frame is divided into a plurality of non-overlapping elementary units, with each elementary unit comprising a plurality of pixels. For elementary units exhibiting change from the prior frame in time, elementary units having pixels with differing digitized color and luminance data are selected for pattern matching. Each pixel of an elementary unit selected for pattern matching is mapped to a pattern value. A pattern value is the same for all pixels sharing the same color and luminance data in an elementary unit. The pattern values are then grouped based on relative position in the elementary unit into offsets into associated sets of pattern match tables and error condition tables. The pattern match tables and error condition tables all relate to a single table of patterns. Entries from the offsets into each associated set of pattern match and error condition tables are then accumulated to generate indicia of pattern matches. The indicia are then compared to select a pattern which best matches the elementary unit within a preselected error tolerance. An offset into a table of patterns for the matched pattern is then generated to provide the desired code.
