ABSTRACT:
A method and apparatus for measuring the cross-sectional or three-dimensional form of an object using video cameras. The object or the camera means is moved to provide a partial overlap on the measurement object, and local form segments of the object are measured and the segments are connected to synthesize a stereo image of the form of the object, unaffected by fluctuations in the motion of the measurement system.
