Abstract
Abstract Signals having indications useful in defining the location of an object surface point in space are generated from a twodimensional record encoded in accordance with an object surface irradiating succession to provide information additional to record-contained x, y positional coordinate data for the surface point. In a preferred practice, adjacent portions of an object are successively irradiated and a corresponding series of photographic records is made. For each object surface point of interest in the records, a signal is generated having x, y positional coordinate data for such point and having further content indicating the order in the record succession of those records including such point.
