Abstract

PURPOSE:To automatically inspect shape and dimensions of parts complicated in the shape with ease by a method wherein shapes to be inspected as drawn by unit working lines are subdivided into simple shapes and rectangular areas are determined corresponding to positions of the shapes thus subdivided to analyze the shape and dimensions of figures therewithin. CONSTITUTION:A light is irradiated on an article 1 to be inspected on a sample base 10 with a lighting device 11 and converted into electrical signals with a scanning type photoelectric converter 12 from the top thereof. Then, it is sampled with a digitalization circuit 13 at intervals of fixed time. Object parts of a part brightly lighted are converted into ''1'' and other parts thereof into ''0'', signals depending on the brightness at sampling points which are introduced to an AND circuit 14 to take ''AND'' with an area signal from an area signal generation circuit 15. Only graphic signals from specific areas within a picture are introduced into an edge data preparation circuit 16, from data are sent to an edge data extraction circuit 17 to calculate data of edge shape and dimensions.
