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.
Claims25
A method for 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 the image capturing device 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, the linear portion of the image including a fraction of the image, the fraction being of a small number of pixels in width relative to a number of pixels in an overall width of the image;
- 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;
- and
- providing said scan line data extracted from said images and said respective positional data to one or more remote devices, said scan line data configured to be processed by said one or more remote devices to generate a realistic view of said route, said processing comprising using said respective positional data for said scan line data and other respective positional data associated with other scan line data received from one or more other image capturing devices that traveled along said route to stitch said scan line data together with said other scan line data to generate said realistic view of said route, and augmenting, by said one or more remote devices, a map database by storing in said map database said realistic view of said route.
A device for generating route data, comprising at least one processor and a memory coupled to the at least one processor, wherein the at least one processor is arranged to:
- receive a position data feed pertaining to a position of an image capturing device travelling along a route in a navigable network;
- receive images of the route captured using the image capturing device as the image capturing device progresses along the route so as to obtain a view of the route;
- extract scan line data from said images, said scan line data comprising a linear portion of the image of a predetermined width that extends along a scan line of a predetermined shape, the linear portion of the image including a fraction of the image, the fraction being of a small number of pixels in width relative to a number of pixels in an overall width of the image;
- store said scan line data in the memory together with respective positional data for the scan line, wherein said positional data is based on the position data feed;
- and
- provide said scan line data extracted from said images and said respective positional data to one or more remote devices, said scan line data configured to be processed by said one or more remote devices to generate a realistic view of said route, said processing comprising using said respective positional data for said scan line data and other respective positional data associated with other scan line data received from one or more other image capturing devices that traveled along said route to stitch said scan line data together with said other scan line data to generate said realistic view of said route, and augmenting, by said one or more remote devices, a map database by storing in said map database said realistic view of said route.
A non-transitory computer readable medium comprising instructions which, when executed by one or more processors of a device, cause the device to perform a method for generating route data, the method 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 the image capturing device 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, the linear portion of the image including a fraction of the image, the fraction being of a small number of pixels in width relative to a number of pixels in an overall width of the image;
- 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;
- and
- providing said scan line data extracted from said images and said respective positional data to one or more remote devices, said scan line data configured to be processed by said one or more remote devices to generate a realistic view of said route, said processing comprising using said respective positional data for said scan line data and other respective positional data associated with other scan line data received from one or more other image capturing devices that traveled along said route to stitch said scan line data together with said other scan line data to generate said realistic view of said route, and augmenting, by said one or more remote devices, a map database by storing in said map database said realistic view of said route.
