  • Patent number: 4803735
    Abstract: There are disclosed a method and an apparatus for properly recognizing the position and orientation of a whole object article from its partial shape. The method comprises the steps of first extracting an image of a partial shape from a two-dimensional picture image representing at least one portion of the object article whose position and orientation are to be recognized, then calculating at least one of a center of gravity, an intersection of straight lines and a linear equation with respect to each of the extracted feature shapes, thereby obtaining at least one feature parameter, and calculating the position and orientation of the whole object article by arbitrarily combining such feature parameters.

  • Patent number: 4748675
    Abstract: A method for controlling an image processing device wherein the contour of a certain segment of an image, or pattern is polygonal-approximated so that it is represented by a row of vertex data and the row of vertex data is processed to recognize the shape of the segment. This method comprises the steps of describing an image processing procedure as a program by a programming language incorporating a group of image processing instructions, and executing this program by the image processing whereby several different image procedures can be performed for image processing according to different uses. This method also controls the image processing procedure using a program written by a programming language incorporating variables representing the structure inherent in the image data.
