US 2023/0418084 A1 · DIFFRACTION-GRATING-BASED SYSTEMS AND METHODS FOR STEREOSCOPIC AND MULTISCOPIC IMAGING

Abstract

Stereoscopic and multiscopic imaging methods and systems are disclosed. An example method can include capturing, with a first image capture device, first image data from a scene within a first field of view, and capturing, with a second image capture device, second image data from the scene within a second field of view overlapping with the first field of view over a stereoscopic overlap region, wherein either or both of the first and second image capture devices include a transmissive diffraction mask (TDM) configured to encode TDM depth information in the first and/or second image data. The method can also include determining stereoscopic depth information within the stereoscopic overlap region based on the first and second image data, determining the TDM depth information encoded in first and/or second image data, and generating combined depth information based on the stereoscopic depth information and the first and/or second TDM depth information.

Dependent claims

An imaging system for imaging a scene, the imaging system comprising:

a plurality of image capture devices comprising:
a first image capture device having a first field of view of the scene, the first image capture device being configured to capture first image data from the scene within the first field of view, the first image capture device comprising a first transmissive diffraction mask (TDM) configured to encode first TDM depth information about the scene in the first image data;
and
a second image capture device having a second field of view of the scene different from the first field of view and overlapping with the first field of view over a stereoscopic overlap region of the scene, the second image capture device being configured to capture second image data from the scene within the second field of view;
and
a computer device operatively coupled to the plurality of image capture devices, the computer device comprising a processor and a non-transitory computer readable storage medium having stored thereon computer readable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:
receiving the first image data from the first image capture device;
receiving the second image data from the second image capture device;
determining stereoscopic depth information about the scene within the stereoscopic overlap region based on the first and second image data;
determining the first TDM depth information encoded in the first image data;
and
generating combined depth information about the scene based on the stereoscopic depth information and the first TDM depth information.
