摘要

A television camera (10) is mounted in a measurement machine (5) so as to have complete freedom for positioning of the camera within the measurement volume of the machine, thereby replacing the taking of manual points and definition of the trajectories of the traditional measurement systems utilising feelers with a simple imaging of the surface portion to be measured. The system comprises an image processor (16) which controls the capture of two different images of the surface to locate the lines of strong contrast. A stereo processor (17) then provides for correlation between the points of the two images, calculation of the three-dimensional coordinates of these points and of the equations of the curves and the surfaces passing through these points.
