Abstract: Disclosed is a method of detecting the position of a symmetric article by converting image signals of the article to binary information and detecting the position of the article based on said binary information. A first median point is determined from binary information corresponding to two points of intersection between a first straight line intersecting said article and the sides of said article, and a second median point is determined from binary information corresponding to two points of intersection between a second straight line passing through said first median point and crossing said first straight line at right angles and the sides of said article. Sequentially, 3rd to (n-1)th median points are similarly determined from binary information, and finally, an n'th median point is determined from binary information corresponding to two points of intersection between an n'th straight line passing through the preceding (n-1)th median point and crossing the preceding (n-1)th straight line at right angles and the sides of said article. The position of the symmetric article is detected by using said n'th median point as the central point of the article.
