Abstract
Disclosed is a system for determining the contour of a plane form in which system the plane form is exposed to an industrial television camera; the video signal from the camera is converted into a train of binary signals '1' or '0', depending on whether a sampling point is bright or dark on the photo-electric converting plane of the camera; and the contour of the plane form is determined from the incremental length of the camera movement relative to the plane form or from the amount of the phase-shift of the sampling pulse required for causing the inversion of binary signals at the sampling points close to the contour of the plane form.
