Abstract:
The registration of images captured at multiple locations, for purposes such as location mapping, can be improved by utilizing multiple image capture elements pointing in at least two different directions or having different viewable ranges. At least one primary image is captured at each location. If the primary image is not able to be correlated with at least one other image based on one or more matching features, image information captured by at least one other camera at substantially the same times as those images can be analyzed to attempt to determine a change in position and/or orientation of the device between those times, which can assist in correlating the primary images. In some embodiments, motion or orientation determining elements can assist in the determination of device movement, and in at least some embodiments can reduce the amount of image information to be processed for a match.
