Abstract
Systems and methods are provided for alternating projection of content and capturing an image. The method includes steps of projecting, by a projection device, content at a first rate, projecting, by the projection device, a capture frame at a second rate, and capturing, by an image capture device, an image including the capture frame at the second rate, wherein capturing the image comprises capturing the image when the capture frame is projected. Systems and methods provided herein may provide increased tracking accuracy by a projecting a capture frame that does not obscure features in the image.
Claims28
A method, comprising:
- projecting, by a projection device, content at a first rate;
- projecting, by the projection device, a capture frame at a second rate;
- capturing, by an image capture device, an image when the capture frame is projected;
- and
- performing a computer vision function based at least in part on the captured image.
A system, comprising:
- a projection device configured to project content at a first rate and a capture frame at a second rate;
- an image capture device configured to capture an image when the projection device projects the capture frame;
- one or more processors coupled to the projection device and the image capture device, the one or more processors configured to process the captured image and generate the content or determine a location or orientation of the content for projection based at least in part on the captured image;
- and
- a memory coupled to the one or more processors.
A system, comprising:
- means for projecting content at a first rate;
- means for projecting a capture frame at a second rate;
- and
- means for capturing an image when the capture frame is projected;
- and
- means for performing a computer vision function based at least in part on the captured image.
A non-transitory computer-readable medium including instructions that when executed by one or more processors cause the one or more processors to perform a method, comprising:
- projecting content at a first rate;
- projecting a capture frame at a second rate;
- and
- capturing an image when the capture frame is projected;
- and
- performing a computer vision function based at least in part on the captured image.
