  • Patent number: 5173945
    Abstract: A process and apparatus are provided for estimating the movement of a moving object relative to a reference object. A symbol is formed on the moving object, the symbol having a rectilinear contour with at least two parallel straight lines. The symbol is observed from the reference object and the movement is determined by means of successive projections along two axes having a relative rotary movement with respect to the recorded image of the symbol. The rotary motion is preferably at such a rate that it does not interfere with obtaining images of the straight lines.
