Abstract

The position and orientation of a geometric figure are detected by sequentially producing the coordinates with respect to an orthogonal coordinate system of pixels which make up an image of the geometric figure, by singling out from these sequentially produced coordinates of these pixels the coordinates of certain characteristic pixels of these pixels which make up an image of the geometric figure, and by comparing these coordinates of these certain characteristic pixels with stored information. Preferably, the certain characteristic pixels are: that pixel, of those which have the least value of one coordinate, which has the least value of the other coordinate; that pixel, of those which have the greatest value of the one coordinate, which has the least value of the other coordinate; that pixel, of those which have the least value of the other coordinate, which has the least value of the one coordinate; and that pixel, of those which have the greatest value of the other coordinate, which has the least value of the one coordinate. A device is also disclosed for performing this method.
