  • Method for detecting the position of a symmetrical article

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.
