Generating navigation data
First Claim
1. A method of generating navigation data, the method including:
- receivinga new experience data set relating to a new experience capture, andat least one stored experience data set relating to at least one previous experience capture,each of the new experience data set and the at least one stored experience data set including a set of nodes, each said node comprising a series of visual image frames relating to a geographical location taken over a series of time frames;
obtaining a candidate set of said nodes from the at least one stored experience data set that potentially relate to a same geographical location of a said node in the new experience data set;
checking whether the geographical location of a said node in the candidate set matches the geographical location of the node in the new experience data set; and
responsive to the matching, adding, to a place data set usable for navigation, a topological link that relates the node in the candidate set to the matched node in the new experience data set.

Abstract
Navigation data is generated by receiving (502) a new experience data set (321) relating to a new experience capture. At least one stored experience data set (320) relating to at least one previous experience capture is also received (504). An experience data set includes a set of nodes, with each node comprising a series of visual image frames taken over a series of time frames. A candidate set of said nodes is obtained (506) from the stored experience data set that potentially matches a said node in the new experience data set, and then a check (508) if performed to see if a node in the candidate set matches the node in the new experience data set. If the result of the checking is positive then data relating to the matched nodes is added (510) to a place data set useable for navigation, the place data set indicating that said nodes in different said experience data sets relate to a same place.

13. Apparatus configured to generate navigation data, the apparatus including:
-
a device configured to receive a new experience data set relating to a new experience capture, and at least one stored experience data set relating to at least one previous experience capture, each of the new experience data set and the at least one stored experience data set including a set of nodes, each said node comprising a series of visual image frames relating to a geographical location taken over a series of time frames; a device configured to obtain a candidate set of said nodes from the at least one stored experience data set that potentially relate to a same geographical location of a said node in the new experience data set; and a device configured to check whether the geographical location of a said node in the candidate set matches the geographical location of the node in the new experience data set, and responsive to the matching, to add, to a place data set usable for navigation, a topological link that relates the node in the candidate set to the matched node in the new experience data set. - View Dependent Claims (14, 15)

17. A non-transitory computer program product comprising computer code that when executed by one or more processors cause a process to be carried out, the process comprising:
-
receiving a new experience data set relating to a new experience capture, and at least one stored experience data set relating to at least one previous experience capture, each of the new experience data set and the at least one stored experience data set including a set of nodes, each said node comprising a series of visual image frames relating to a geographical location taken over a series of time frames; obtaining a candidate set of said nodes from the at least one stored experience data set that potentially relate to a same geographical location of a said node in the new experience data set; checking whether the geographical location of a said node in the candidate set matches the geographical location of the node in the new experience data set; and responsive to the matching, adding, to a place data set usable for navigation, a topological link that relates the node in the candidate set to the matched node in the new experience data set. - View Dependent Claims (18, 19, 20)
