Possible Prior Art
One possible prior art in depth sensing technology is the use of structured light or time-of-flight cameras to capture depth information in various applications. These methods have been used in industries such as gaming, 3D scanning, and facial recognition.
What are the specific illumination configurations used in the method described in the patent application?
The specific illumination configurations mentioned in the patent application are the first illumination configuration, which involves illuminating the scene with a first type of illumination, and the second illumination configuration, which involves illuminating the scene with a second type of illumination different from the first.
How does the technology address multipath interference in depth sensing?
The technology addresses multipath interference in depth sensing by obtaining multiple depth images of a scene under different illumination configurations and then determining the multipath interference associated with the first depth image based on the second depth image. This information is used to generate an adjusted depth image that includes both original pixels and adjusted pixels to mitigate the effects of multipath interference.
Original Abstract Submitted
Systems and techniques are described for depth sensing. For example, a method can include obtaining a first depth image of a scene. The first depth image of the scene is associated with a first illumination configuration including illuminating the scene with a first type of illumination. The method can include obtaining a second depth image of the scene, wherein the second depth image is associated with a second illumination configuration, different from the first illumination configuration. The second illumination configuration includes illuminating the scene with a second type of illumination. The method can include determining, based on the second depth image, multipath interference (MPI) associated with the first depth image. The method can further include generating based on determining the MPI associated with the first depth image an adjusted depth image including one or more pixels from the first depth image and one or more adjusted pixels.
