    摘要: Upon initiation of a initiation processing by a task management, reference is made to a initiation table for processing of initiation, and processing of measurement is performed by an input measurement processing in response to the preset timing. Then the input value is stored in a input value storage buffer. When an application program is acquired, an input value acquisition processing is initiated, the input value is from the buffer, and is transferred to the application program. When the application program is set, an output value updating is initiated, the output value having been transferred from the application program is updated, and the result is stored in an output value storage buffer. Further, output processing means is initiated in response to the timing preset on the initiation table and an output value is outputted from the output value storage buffer.

    摘要: The imaging position of each of the frames in image data of a plurality of frames captured while a vehicle is traveling is accurately determined.An image data acquiring device (100) captures a front image by means of a video camera (120) while a vehicle is traveling. When in imaging, the device associates the vehicle speed pulse detected by a vehicle speed sensor (104) with the frame data and records them. An image data processing device (200) arranges data on each frame of the image along the initial path according to the correspondence with the vehicle speed pulse. The device determines the variation between the frames of a feature point such as a road lane marking included in the image, reflects the variation on the initial path, and corrects the errors in the direction perpendicular to the moving direction so as to determine the traveling path and imaging positions of the frames.With this, the accuracy in determining the imaging position of each frame is improved.

    摘要: A route guidance device is provided with a two-dimensional road network for a route search, a three-dimensional road network for a route guidance, and guiding line shape data. The guiding line shape data is three-dimensional guidance display data for guiding an operator to go straight through, or to make a right turn, left turn, etc. at intersections in accordance with a passage mode, or to switch lanes before entering an intersection. A link node of the two-dimensional road network is associated with the guiding line shape data through the three-dimensional road network. The route search uses the two-dimensional road network, and the route guidance uses the guiding line shape data associated with the link node acquired by the route search. The present invention can realize an instinctively understandable route guidance that follows a passage mode without increasing a load of a route search.
