A range-finding system comprising the hardwired video processing of two side-by-side TV stereo images of a scene to provide automatic, rapid, quantitative ranging to noncooperative objects. A single TV camera with appropriate optics to provide stereo inputs or, in a preferred embodiment, two TV cameras, provide the stereo images. Range is determined for any change of contrast in the common TV stereo scene to obtain the parallax displacement of corresponding object features with a three scan line delay of less than 200 microseconds. The video of the synchronized line scan of both cameras is stored as they are scanned, thus range can be determined with relative motion between the stereo camera and objects in the scene. Range is stored in on-board RAM\s for each pixel of the TV scene and is available after three TV lines of delay. Range up-dating is continuous as the TV raster is scanned, or the range of a particular TV frame may be frozen for detailed study. Any part of the electromagnetic spectrum that can provide TV imagery can be used in the ranging system.

A TV system for the automatic quantitative ranging on at least a single remote, non-cooperating, passive object comprising: means for presenting a scene containing said object on a light-sensitive mosaic of a line-scannable image sensing means in the form of a pair of side-by-side split-screen stereo images of said scene; means for scanning said mosaic in a horizontal sequence of scanning lines for successively analyzing the image energy along said scanning lines and deriving output signals proportional to the light energy of features of said stereo object images, each of said scanning lines having a predetermined number of scan points; means for counting the scan points in each image of the stereo image pair in each scanning line to said features of said object in each scene from the left side of each image pair such that the parallax displacement D
