Abstract
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.
Claims20
A method comprising:
- accessing scan line data and corresponding positional data,
- wherein the scan line data is determined based on a plurality of images captured by a plurality of devices, wherein each device of the plurality of devices captured at least one image of at least one route of a navigable network, and
- wherein the corresponding positional data is received as a plurality of positional data feeds, each of the plurality of positional data feeds associated with a corresponding device of the plurality of devices on the navigable network;
- and
- extracting at least one route-specific feature from the scan line data.
A system including at least one processor to execute program code to cause the system to perform operations comprising:
- accessing scan line data and corresponding positional data,
- wherein the scan line data is determined based on a plurality of images captured by a plurality of devices, wherein each device of the plurality of devices captured at least one image of at least one route of a navigable network, and
- wherein the corresponding positional data is received as a plurality of positional data feeds, each of the plurality of positional data feeds associated with a corresponding device of the plurality of devices on the navigable network;
- and
- extracting at least one route-specific feature from the scan line data.
