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 1):
A method of perceiving a spatial model of a working environment, the method comprising:\n capturing data by one or more sensors of a robot moving within a working environment, the data being indicative of depth within the working environment from respective sensors of the robot to objects in the working environment at a plurality of different sensor poses; obtaining, with one or more processors of the robot, a plurality of depth images based on the captured data, wherein:\n respective depth images are based on data captured from different positions within the working environment through which the robot moves, \n respective depth images comprise a plurality of depth data, the depth data indicating distance from respective sensors to objects within the working environment at respective sensor poses, and \n depth data of respective depth images correspond to respective fields of view; \n aligning, with one or more processors of the robot, depth data of respective depth images based on an area of overlap between the fields of view of the plurality of depth images; and determining, with one or more processors of the robot, based on alignment of the depth data, a spatial model of the working environment.
