Abstract
In one embodiment, a method is disclosed for a robot (e.g., cleaning robot) to produce a bird's eye view (planar) map by transforming from a robot camera view and stitching together images tagged by location. The planar map can then be presented on a user interface as a floorplan, showing the location of objects (such as rugs). A camera is mounted in the cleaning robot sufficiently high in the cleaning robot housing to provide an angled view downward at a floor. The camera's field of view is captured as an image, and a portion or segment of that image is cropped. The cropped segment is transformed from the camera perspective to a planar view (before or after cropping), and is combined with other images to form a map of a floorplan.
