Patent ID: 7804528

Claim:
An information processing apparatus comprising: a storing device configured to store data items which include measured position information in association with position time information at which the measured position information is obtained, wherein the measured position information and the position time information are obtained at predetermined intervals; a transferring device configured to transfer the stored data items from the storing device to a recording device; the recording device configured to receive and record the data items from the storing device, and to receive and record image data from an external imaging device, the image data including image time information indicating a time of acquiring the image data at the external imaging device; and a matching unit configured to compare the image time information included in the image data with the position time information included in the data items, wherein when the compared image time information and position time information match, a position of the external imaging device at the time of acquiring the image data is estimated on the basis of a measured position information associated with the matching position time information, and when the compared image time information and position time information do not match, the position of the external imaging device at the time of acquiring the image data is estimated on the basis of at least two measured position information associated with at least two respective position time information corresponding to the image time information.
