摘要： An image processing apparatus for effecting a series of processes for capturing an image and scrutinizing the captured image is disclosed. Each process in series of processes is selected from different modes of processes. Selector selects a mode of process for each of the series of processes. A preselected number of parameters are set for each of the selected mode of processes, and the set parameters are stored in a parameter memory sequentially. Mode data indicative of the selected modes for the series of processes are stored in the mode memory. A parameter number table informs the number of parameters necessary for each mode in each of the series of processes. When the parameters and the mode data are read from the parameter memory and said mode memory, respectively, parameter allocator allocates and produces proper parameters to corresponding modes of processes with reference to the parameter number table.

摘要： Deviation between an upper portion and a lower portion of a screw hole is recognized. This is accomplished by imaging holes in respective objects to obtain a contrast image. The position of the hole in the upper object and the lower object is detected. The deviation between the positions is calculated. Screws are tightened sequentially beginning with the hole having the smallest deviation. The rotation angle of the object to be tightened is determined. From this rotation angle, the deviation of other holes is calculated.

摘要： Each pixel of a density reference area of a reference image is assigned a predetermined coefficient value in accordance with whether the pixel is located within a peripheral boundary of a to be detected shape, external the peripheral boundary of the to-be-detected shape, or on the peripheral boundary of the to-be-detected shape. An actual image of an object containing the to-be-detected shape is then obtained, and after setting a target pixel of the resultant image, the image density of each pixel is multiplied by the coefficient values of the density reference area of the reference image. The resultant products are transformed into a density correlation value for the target pixel. The location of the target pixel is then scanned to determine the location of a target pixel at which a maximum or a minimum density correlation value is obtained. The thus determined location is detected as the location of the to-be-detected shape within the object.

摘要： A position detection apparatus for detecting a position of an object includes a video image producer which produces a video image signal representing the object image. The video image signal is divided into first and second level portions by an edge point. An edge point detector detects the edge point where said level difference is greater than a threshold level. A window filter is provided to increase this level difference to a level greater than a threshold so that the edge point detector can detect the edge point even when the level difference is smaller than the threshold level. A shape detector detects the position of the object based on thus detected edge point.

摘要： An alignment detection apparatus is able to accurately detect the alignment condition of an upper hole and a lower hole located under the upper hole even when a scanning window does not precisely match either of the two holes. This alignment detection apparatus comprises an image producer which produces a digital density image indicative of these two holes. A position detector detects positions of the holes based on the digital image signal and produces a position signal. A displacement detector detects a distance between the upper hole and lower hole based on the position signal and produces a displacement signal indicative of the thus detected distance. Based on the displacement signal, the alignment condition of two holes including the information of how the lower hole edge is displaced from the upper hole edge can be detected.

摘要： Positions of overlapping first and second circular holes of respective first and second objects are detected, the first and second objects to be screwed together by a robotic screwing mechanism. An upper surface of the first object is viewed with an image pick-up device to obtain an image of the first circular hole and a partial image of the second circular hole which overlaps the image of the first circular hole. Two maximally spaced-apart boundary points from among the boundary points along an outer periphery of the partial image are detected. First and second circles within an image frame are defined which include the two maximally spaced-apart boundary points and which have respective centers of gravity which are symmetric to each other relative to a line segment connecting the maximally spaced-apart boundary points. The positions of the first and second circular holes are detected based on the defined first and second circles within the image frame.
