Abstract
An article under inspection is rotated at pre-set angular increments which total more than 360.degree., to divide the figure inscribed on the curved surface of the article into plural fractions. Selected picture fractions which discard redundant overlapping picture data, is synthesized into picture information indicative of one full-format picture based on which the figure inscribed on the curved surface of the article. Acceptability is determined automatically and quantitatively as compared to the conventional functional inspection and is performed without regard to the difference in skill from one operator to another. Recognizing the characters or symbols inscribed on the curved surface of the article under inspection one by one based on the information of the synthesized full-format picture, allows a comparison of the character string consisting of the recognized characters or symbols to a pre-set control character string.
