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