Title: Method for detecting and processing defective
Inventor: ABE HIROKATSU
IPC: G06T7/00
Filed: 1993-06-29
Abstract: PURPOSE:To enhance the efficiency of arithmetic processing and to prevent misjudgment by automatically correcting an average reference value for the range of non- defective products according to variation in real time, and obtaining a correction reference value. CONSTITUTION:An image of a subject for inspection, e.g. a bottle 1, is sampled by a camera 2 and its image signal is immediately subjected to arithmetic processing by an image processing portion 3, and the image undergoes simple binarization for image processing, and a reference value (preferably with the addition as a tolerance of three times a standard deviation alpha calculated from the measured values of (n) non-defective products) A, initialized by a data input setting portion 4, is used to determine whether or not the subject 1 for inspection is defective. The reference value A is within a range G of non-defective products which is given by adding allowable error values C, C to the upper and lower correction limit values B, B of the average reference for measured values of every (n) subjects 1 for inspection. The reference value A within the range G is automatically corrected according to variation even in real time during operation, to obtain a reference correction value A1. Correction allowable values C1, C1, automatically shifted to a reference value derived from the correction value A1, define a range G1 of non-defective products, which is used to determine whether or not the subjects 1 for inspection are defective.
