    摘要: 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 (2) 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.

    摘要: A method and an apparatus for cresting surface mounted device such as the IC (31) or the like by the hand (33) of the robot and automatically and accurately loading them onto the contact pattern of the printed board by means of the image processor (7) are disclosed. According to this method, the measurement line (17) is provided onto each image pattern of the pin array of the surface mounted device and the array of the contact pattern of the board, so that it may intersect at right angles with the direction of the pattern, and each position of the pin array and the array of the contact pattern is sought from the variation of the brightness (I,II,...) on that line. In accordance with the result thus obtained, displacement of the position and that of the rotation over the entire surfaced part and the contact pattern are sought and the operation of the robot (1-10) is controlled in accordance with that information.

    摘要: In a partial pattern matching system, a dictionary pattern, a pattern to be recognized and a binary-coding unit for giving a binary-coded image pattern by comparing each pixel with a predetermined voltage (10, 101 to 103) are provided. A polygonal approximation unit (104) gives a coordinate string of vertices of a polygon composed of a plurality of successive straight line segments approximately representing a contour of the binary-coded image pattern. A contour segmentation unit (106) judges a corner point among the vertex coordinates of the polygon based upon a criterion dependent upon the shape of the polygon. the corner point being used for dividing the polygon into a plurality of partial pattern. In a matching unit (107, 109), a correspondence pair is given by subjecting each combination of the partial patterns of the dictionary and recognition-object patterns to matching comparison, and each evaluation of matching degree is given for each of the correspondence pair.
