    摘要: A computer hardware and software system and method for displaying a map of streets corresponding to an area over which a vehicle may move to assist a driver to navigate, the system displaying the map on a display based on a scale-dependent street prioritization scheme, providing on the display a vehicle position symbol indicating the current position and heading of the vehicle and a moving map which moves in translation and rotation as the vehicle moves, selectively and dynamically labelling streets on the display as the vehicle moves, and providing a destination symbol on the display indicating a desired destination or the direction to a desired destination.

    摘要: Disclosed is an apparatus generating accurate data regarding the heading of a land vehicle as it travels over terrain having changing conditions. The apparatus includes a first sensor means, such as a differential odometer, generating data regarding the relative direction of the vehicle. Also included is a second sensor means, such as a flux gate compass, for generating data regarding the absolute direction of the vehicle relative to the earth. The relative directional data and the absolute directional data are combined in a means for generating accurate data regarding the heading of the vehicle. A means for reducing errors reflected in signals generated by the sensors is provided to insure the accuracy of the output.

    摘要: An object is detected in images of a live event by storing and indexing camera registration-related data from previous images. For example, the object may be a vehicle which repeatedly traverses a course. A first set of images of the live event is captured when the object is at different locations in the live event. The camera registration-related data for each image is obtained and stored. When the object again traverses the course, for each location, the stored camera registration-related data which is indexed to the location can be retrieved for use in estimating a position of a representation of the object in a current image, such as by defining a search area in the image. An actual position of the object in the image is determined, in response to which the camera registration-related data may be updated, such as for use in a subsequent traversal of the course.
