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.
