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 3):
The method of  claim 1 , wherein:\n depth data is associated with respective values indicating respective angular displacements of corresponding depths in respective frames of reference corresponding to respective fields of view; the depth images are obtained by triangulating object depths based on captured angles at which a laser emitted from the robot and reflecting off respective objects is received at a camera sensor of the robot; the plurality of depth data comprises a plurality of depth vectors from the sensor to objects within the working environment, respective vectors including at least one coordinate indicating relative position in a respective field of view and at least one coordinate indicating depth; and at least some of the fields of view partly overlap with a respective preceding field of view.
