  • Patent number: 5530441
    Abstract: A method and an apparatus for measuring traffic flows, or in other words the flows of vehicles, inside and near a crossing. The method and apparatus are capable of extracting vehicles with a high level of accuracy. Overlap of vehicles can be avoided by setting the field of a camera to exclude a range from the inflow portion to the vicinity of center of the crossing but to include a range from the center to the vicinity of the outflow portion of the crossing. Accordingly, accuracy of traffic flow measurement can be improved.

  • Patent number: 5159664
    Abstract: A graphic processor comprises an input device for inputting a command from an operator, a display device for displaying graphic data and a computer for preparing and correcting graphic data by a command input from the operator and for making display control of the display device. When the operator wants to know the content of the command that is executed, he instructs the command to the computer. A command name, a processing content and a figure as an object of processing are calculated from history data instructed from the computer. The figure as the object of processing, the command processing content and the relation of correspondence are symbolized and displayed on the display device. Furthermore, a parametric figure is also displayed visually on the display device.

  • Patent number: 4982438
    Abstract: A three-dimensional shape of an object is recognized by developing enveloping surfaces of the object by a cone-silhouetting method, wherein the object is picked up by a binocular three-dimensional vision method by making use of geometrical restraint conditions derived by the cone-silhouetting method. The binocular parallax is increased to thereby ensure the recognition of the three-dimensional shape with improved accuracy. Local concave portions which can not be recognized by the cone-silhouetting method by itself are recognized with higher accuracy.

  • Patent number: 4500951
    Abstract: In a plant control system, a transmission channel includes loop transmission lines arranged in duplex. Equivalently connected to this transmission channel are a plurality of one-loop controller stations, a backup station backing up a disabled one of the plural controller stations and a display station for displaying the status of the controller stations and the backup station. Each of the controller stations, backup station and display station includes a built-in microcomputer. Each of these stations includes also a transmission interface circuit and a self-diagnostic circuit. The transmission interface circuit in each station selects one of the transmission lines for data transmission between its own station and the others. The self-diagnostic circuit in each station detects the presence of failure of normal operation of its own station and disconnects the disabled station from the transmission line, so that the other stations may not be adversely affected by the disabled station.
