Using multiple cameras to stitch a consolidated 3D depth map
First Claim
1. A device comprising:
- at least one computer medium that is not a transitory signal and that comprises instructions executable by at least one processor to;
generate, using a first device, at least a first image of second and third devices in a field of view of a camera;
the first image being a first 3D depth map;
receive from at least one of the second and third devices information useful for generating a second 3D depth map including an image of the first device; and
generate an aggregate 3D depth map using the first and second 3D depth maps.

Abstract
Each of plural devices includes a laser emitter and a camera for detecting reflections of laser light emitted by the device, so that plural of the devices can generate their own depth maps showing images within the field of view of their cameras. The resulting 3D depth maps from multiple cameras at potentially arbitrary locations can be aggregated to create a more accurate 3D depth map of the area covered by all the individual cameras. Each device/camera may be assigned a unique identification such as a unique number and a mechanism to identify, either electronically or visually, devices in its field of view. Using this information, the relative locations of the cameras can be calculated for purposes of aggregating the multiple depth maps.
