Abstract:
Examples described herein relate to mapping a space using a multi-directional camera. This mapping may be performed with a robotic device comprising a monocular multi-directional camera device and at least one movement actuator. The mapping may generate an occupancy map to determine navigable portions of the space. A robotic device movement around a point in a plane of movement may be instructed using the at least one movement actuator. Using the monocular multi-directional camera device, a sequence of images are obtained ( 610 ) at different angular positions during the instructed movement. Pose data is determined ( 620 ) from the sequence of images. The pose data is determined using features detected within the sequence of images. Depth values are then estimated ( 630 ) by evaluating a volumetric function of the sequence of images and the pose data. The depth values are processed ( 640 ) to populate the occupancy map for the space.

Claim (Index 1):
A robotic device comprising:\n a monocular multi-directional camera device to capture an image from a plurality of angular positions; at least one movement actuator to move the robotic device within a space; a navigation engine to control movement of the robotic device within the space; an occupancy map accessible by the navigation engine to determine navigable portions of the space, wherein the navigation engine is configured to:\n instruct a movement of the robotic device around a point in a plane of movement using the at least one movement actuator; \n obtain, using the monocular multi-directional camera device, a sequence of images at a plurality of different angular positions during the instructed movement of the robotic device; \n determine pose data from the sequence of images, the pose data indicating the location and orientation of the monocular multi-directional camera device at a plurality of positions during the instructed movement, the pose data being determined using a set of features detected within the sequence of images; \n estimate depth values by evaluating a volumetric function of the sequence of images and the pose data, each depth value representing a distance from the multi-directional camera device to an object in the space; and \n process the depth values to populate the occupancy map for the space.
