METHODS AND SYSTEMS FOR GENERATING ROUTE DATA

摘要

A device is provided to extract scan lines data from images of a route, said scan line data comprising only a portion of the an image that extends along a scan line, and to store this data in memory together with respective positional data pertaining to the position of the device traveling along the route in a navigable network. This scan line and positional data can be obtained from a plurality of devices in a network and transmitted to computing apparatus, for example, for use in a production of a realistic view of a digital map.

1. A method of continuously generating route data, comprising:
receiving a position data feed pertaining to a position of an image capturing device travelling along a route in a navigable network; receiving images of the route captured using the image capturing device as it progresses along the route so as to obtain a view of the route; extracting scan line data from said images, said scan line data for an image comprising a linear portion of the image of a predetermined width that extends along a scan line of a predetermined shape; and storing said scan line data in memory together with respective positional data for the scan line, wherein said positional data is based on the position data feed.
