摘要： A method of compressing data output from one or more accelerometers configured to be transported, carried or worn by a user is provided. Acceleration values indicative of the movement of the user are measured at a first frequency and values representative of the measured acceleration values are generated at a second frequency, which is lower than the first frequency. The step of generating comprises: defining a plurality of time windows, each time window containing a plurality of measured acceleration values; and applying a transformation to the measured acceleration values within each time window to generate a plurality of transformed values. For each time window, storing at least one of said plurality of transformed values and/or one or more parameters associated therewith.

摘要： A method for use in forming an image of an object comprises setting a value of an attribute of an image of an object according to a measured reflectance of the object. The image of the object thus formed may be realistic and may closely resemble the actual real-world appearance of the object. Such a method may, in particular, though not exclusively, be useful for providing a realistic image of a road surface and any road markings thereon to assist with navigation. Setting a value of an attribute of the image of the object may comprise generating an initial image of the object and adjusting a value of an attribute of the initial image of the object according to the measured reflectance of the object to form an enhanced image of the object. A method for use in navigation comprises providing a navigation system with data associated with an image formed using such a method. An image formed using such a method and a map database containing such an image are also disclosed.

摘要： A method of generating a geodetic reference database product is disclosed The method comprises acquiring mobile mapping data captured by means of digital cameras, range sensors and position determination means including GPS and IMU mounted to a vehicle driving across the earth surface, the mobile mapping data comprising simultaneously captured image data, range data and associated position data in a geographic coordinate system. Linear stationary earth surface features are derived from the mobile mapping data by processing the image data, range data and associated position data. 3D-models are generated for the linear stationary earth surface features in the geographic coordinate system from the image data, range data and associated position data and stored in a database to obtain the geodetic reference database product. A 3D-model could include an image representing the colors of the surface of the 3D model or a set of smaller images representing photo-identifiable objects along the model. The 3D-models could be used to rectify aerial imagery, to correct digital elevation models and to improve the triangulation of digital elevation models.

摘要： This invention relates to a method for updating digital maps and for matching global navigation devices to a digital map. Such navigation devices rely upon GPS signals (20, 24) from satellites (22, 26). One well-documented cause of position error in navigation devices arises from the phenomenon of GPS multi-path. It has been observed that GPS multi-path errors in the latitude/longitude direction are highly correlated with errors in altitude. By comparing altitude value of GPS probe data with reference specifications for altitude, unreliable probe data (outliers) can be easily identified and culled. Such techniques can be used as well by a mobile navigation device to confirm a match to a particular road segment and if not revert to other positioning techniques such as inertial guidance systems and the like. If the local altitude is not reliably known, an estimation can be derived directly from the collected probe data.

摘要： A navigation system for use in a vehicle (402). The system includes an absolute position sensor, such as GPS, in addition to one or more additional sensors, such as a camera, laser scanner, or radar. The system further comprises a digital map or database that includes records for at least some of the vehicle's surrounding objects (400). These records can include relative positional attributes with respect to a reference axis (404). As the vehicle (402) moves, sensors sense the presence of at least some of these objects (400), and measure the vehicle's relative position to those objects. This information is used to determine the vehicle's instantaneous lateral offset (428) relative to the reference axis (404), and support features such as enhanced driving directions, collision avoidance, or automatic assisted driving. The system also allows new objects (408, 414) to be attributed using relative positioning, and thereby factored into the enhanced navigation features.
