Abstract
PURPOSE: To judge a flaw at a high speed, by picking up only the burr part of an object to be inspected as a shade and extracting a flaw part by the binarization and thinning of the image pickup signal of the burr part.
CONSTITUTION: A diffusion plate 2 allows the light from a lower light source to diffuse to allow the whole of an object 1 to be inspected to appear as a shade. An upper light source 4 illuminates the upper surface of the object 1 to leave the burr 5 at the bottom part of the object in a shade state. The image pickup signal obtained by a camera 6 is binarized by the binarization circuit 8 of an image processor 7 and only the part of the burr 5 is extracted. Continuously, the part of the burr 5 extracted by a thinning circuit 9 is thinned and, at this time, a flaw part exceeding the tolerance range of the burr 5 appears as a part markedly protruding from other part. This signal is sent to a 3×3 flaw detection filter 10 and, when the signal coincides with a flaw mask A (at the time of an end point) or a flaw mask B (a line width is other than 1), the product is determined as defective.
