ABSTRACT:
A camera is mountable near the target for generating a composite video signal including the target and a region extending along a predetermined direction from the target. A video signal converter is associated with the camera, for separating the video signal into horizontal and vertical digital data points associated with arbitrary horizontal and vertical axes in the camera. The horizontal data points and the vertical data points are spaced apart by a horizontal unit pitch and a vertical unit pitch, respectively. One of the arbitrary axes is aligned with the predetermined direction of target movement, and calibration establishes a quantitative relation between the unit pitch of the video signal data points along one aligned axis and a known distance along the predetermined direction. The number of digital data points are counted between a reference position of the target and a displaced position of the target on the aligned axis, which is commensurate with the displaced position of the target.
