    摘要: A method for determining an orientation of a line segment in a contour in a local area of a binary contour image. The number of pixels having a predetermined value and located in each orientation in the local area, is obtained, and it is determined that a line segment exists in an orientation in which the number of pixels is large. Further, when it is determined that the number of pixels located in each of a plurality of orientations and having a predetermined value, is greater than a sum of the numbers of pixels in orientations adjacent to said each orientation on both sides thereof, it is determined that a line segment exists in said each orientation. Two orientations in which large numbers of pixels are located are detected, and it is determined whether the point is a constituent of a line segment, a line segment of the sub-straight-line form, or a near-corner point, depending on angles made by the two orientations is equal to 180.degree., or a difference of the angles made by the two orientations from 180.degree.. Contiguously arrayed pixels in the same orientation are detected as a line segment. A position and an orientation are obtained from points near a corner, and representative values of the positions and orientations of contiguously arrayed near-corner points are determined. (FIG. 3)

    摘要: A three-dimensional measuring apparatus including a multi-slit projector has an actuator for displacing at least one of first and second diffraction gratings by only a minute distance in a direction perpendicular to the slit lights. An image recognizing apparatus includes an image arithmetic unit for changing, each time a coded multi-slit light pattern is changed, weights assigned to the binarized image signals, and for summing up the last weighted binarized image signals or the image signals of the last added results read out from an image memory, with newly weighted binarized image signals. This improves the image resolution reduces the memory capacity and increases the processing speed.

    摘要: In a moving-target tracking apparatus for tracking a target moving in a dynamic picture image, color information, differential information and target position information based on a prediction for a motion according to the past motion are detected in the form of two-dimensional map. These maps are merged into a single map. A target position is detected in accordance with the merged map. Thus, an operational ability on a real-time basis and a tracking performance are improved.
