Abstract:
Provided is a method and apparatus for combining perceived depths to construct a floor plan using cameras, such as depth cameras. The camera(s) perceive depths from the camera(s) to objects within a first field of view. The camera(s) is rotated to observe a second field of view partly overlapping the first field of view. The camera(s) perceives depths from the camera(s) to objects within the second field of view. The depths from the first and second fields of view are compared to find the area of overlap between the two fields of view. The depths from the two fields of view are then merged at the area of overlap to create a segment of a floor plan. The method is repeated wherein depths are perceived within consecutively overlapping fields of view and are combined to construct a floor plan of the environment as the camera is rotated.

Claim (Index 10):
The method of  claim 5 , wherein determining the first area of overlap comprises:\n determining an approximate alignment between a reduced resolution version of the first depth image and a reduced resolution version of the second depth image; and refining the approximate alignment by:\n determining aggregate amounts of difference between overlapping portions of the first depth image and the second depth image at candidate alignments displaced from the approximate alignment; and \n selecting a candidate alignment that produces a lowest aggregate amount of difference among the candidate alignments or selecting a candidate alignment that produces an aggregate amount of difference less than a threshold.
