Abstract
A method includes capturing light reflected off one or more objects and splitting the captured light into a plurality of light fields with a plurality of phase curvatures. The method further includes generating, for the one or more objects, a plurality of holograms based on the plurality of light fields and determining, for each of the plurality of holograms, an intensity and a phase-shift of the hologram. The method thus includes generating a depth map comprising depth information for the one or more objects based at least in part on a function determined by the respective phase-shifts of the plurality of holograms.
Claims17
A method comprising, by an electronic device:
- capturing ambient light reflected off one or more objects, wherein the ambient light comprises non-laser light;
- splitting the captured ambient light reflected off the one or more objects into a plurality of light fields with a plurality of phase curvatures;
- generating, for the one or more objects, a plurality of holograms based on the plurality of light fields;
- determining, for each of the plurality of holograms, an intensity and a phase-shift of the hologram;
- and
- generating, for the one or more objects, a depth map comprising depth information for the one or more objects based on a reconstruction of the plurality of holograms, wherein the plurality of holograms are reconstructed based at least in part on a function determined by the respective intensities and phase-shifts of the plurality of holograms.
An electronic device comprising:
- one or more cameras;
- one or more non-transitory computer-readable storage media including instructions;
- and
- one or more processors coupled to the storage media and the one or more cameras, the one or more processors configured to execute the instructions to:
- capture ambient light reflected off one or more objects, wherein the ambient light comprises non-laser light;
- split the captured ambient light reflected off the one or more objects into a plurality of light fields with a plurality of phase curvatures;
- generate, for the one or more objects, a plurality of holograms based on the plurality of light fields;
- determine, for each of the plurality of holograms, an intensity and a phase-shift of the hologram;
- and
- generate, for the one or more objects, a depth map comprising depth information for the one or more objects based on a reconstruction of the plurality of holograms, wherein the plurality of holograms are reconstructed based at least in part on a function determined by the respective intensities and phase-shifts of the plurality of holograms.
A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of an electronic device, cause the one or more processors to:
- capture ambient light reflected off one or more objects, wherein the ambient light comprises non-laser light;
- split the captured ambient light reflected off the one or more objects into a plurality of light fields with a plurality of phase curvatures;
- generate, for the one or more objects, a plurality of holograms based on the plurality of light fields;
- determine, for each of the plurality of holograms, an intensity and a phase-shift of the hologram;
- and
- generate, for the one or more objects, a depth map comprising depth information for the one or more objects based on a reconstruction of the plurality of holograms, wherein the plurality of holograms are reconstructed based at least in part on a function determined by the respective intensities and phase-shifts of the plurality of holograms.
