1. 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 .DELTA. of corresponding object features in the two stereo images can be determined; and means for processing said parallax displacements and producing an output indication of the range characterized by said parallax displacements.
