Abstract
An augmented reality system for procedural guidance identifies a fiducial marker object in a frame of a first field of view generated by a camera, determines a pose of the fiducial marker object, applies the fiducial marker pose to generate a first transformation between a first coordinate system of the fiducial marker object and a second coordinate system of the camera, and applies a pose of a headset to determine a second transformation between the first coordinate system and a third coordinate system of the headset.
Claims20
An augmented reality system comprising:
- a workspace comprising:
- a fiducial marker object;
- one or more fixed position objects;
- and
- one or more moveable objects;
- at least one camera oriented at a downward angle to the workspace, the camera comprising:
- a first field of view;
- and
- a depth sensor configured to generate a depth map;
- at least one headset comprising:
- a mobile camera;
- and
- a second field of view;
- logic to:
- identify the fiducial marker object in a frame of the first field of view;
- determine a pose of the fiducial marker object in the first field of view;
- apply the fiducial marker pose in the first field of view to generate a first transformation between a first coordinate system of the fiducial marker object and a second coordinate system of the fixed position camera;
- and
- apply a pose of the headset to determine a second transformation between the first coordinate system and a third coordinate system of the headset.
A method for generating virtual augmentations in a headset, the method comprising:
- identifying a fiducial marker object in a frame of a first field of view generated by a fixed position camera;
- determining a pose of the fiducial marker object;
- applying the fiducial marker pose to generate a first transformation between a first coordinate system of the fiducial marker object and a second coordinate system of the fixed position camera;
- and
- applying a pose of a headset to determine a second transformation between the first coordinate system and a third coordinate system of the headset.
A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a computer, cause the computer to:
- identify a fiducial marker object in a frame of a first field of view generated by a fixed position camera;
- determine a pose of the fiducial marker object;
- apply the fiducial marker pose to generate a first transformation between a first coordinate system of the fiducial marker object and a second coordinate system of the fixed position camera;
- and
- apply a pose of a headset to determine a second transformation between the first coordinate system and a third coordinate system of the headset.
