Data relating to the distances between each of all the feature points of the article to be checked and the other feature points thereof is stored in a memory in advance. The image of the article is picked up by a camera, and the resulting image data is stored in another memory. With use of a computer, data relating to the distances of at least two of the feature points of the article from other feature points thereof is obtained from the image data. The two feature points are identified by checking the data relating to the distances of the two feature points from other feature points with reference to the stored data relating to the distances between each feature point and the other feature points. The orientation of the article is determined based on the direction through the two identified feature points. |
