ACTIVE DEPTH SENSING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240127401 titled 'ACTIVE DEPTH SENSING
Simplified Explanation
The patent application describes a method for depth sensing using different illumination configurations to obtain multiple depth images of a scene and mitigate multipath interference.
- The method involves obtaining a first depth image of a scene illuminated with a first type of illumination, and a second depth image of the same scene illuminated with a second type of illumination.
- Based on the second depth image, multipath interference associated with the first depth image is determined.
- An adjusted depth image is generated by incorporating information from the first depth image and adjusting pixels affected by 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.
