REAL-TIME PHOTOREALISTIC VIEW RENDERING ON AUGMENTED REALITY (AR) DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18353579 titled 'REAL-TIME PHOTOREALISTIC VIEW RENDERING ON AUGMENTED REALITY (AR) DEVICE

Simplified Explanation

The patent application describes a method for rendering scenes on an augmented reality (AR) device using sparse feature vectors. Here is a simplified explanation of the abstract:

  • The method involves capturing images of a scene and obtaining position data of the device that captures the images.
  • Position data and direction data associated with camera rays passing through keyframes of the images are determined.
  • A position-dependent multilayer perceptron (MLP) and a direction-dependent MLP are used to create sparse feature vectors.
  • The sparse feature vectors are stored in at least one data structure.
  • When a request is received to render the scene on an AR device with a specific viewing direction, the scene is rendered using the sparse feature vectors in the data structure.

Potential Applications:

  • Augmented reality devices: The method can be used in AR devices to render scenes based on the viewing direction, enhancing the user's experience.
  • Gaming: The technology can be applied in gaming to create immersive AR environments where the scenes are rendered based on the player's viewing direction.

Problems Solved:

  • Efficient rendering: The method solves the problem of efficiently rendering scenes on AR devices by using sparse feature vectors, reducing the computational load.
  • Real-time rendering: By using position and direction data, the method enables real-time rendering of scenes on AR devices, providing a seamless experience for the user.

Benefits:

  • Improved user experience: The method allows for more accurate and realistic rendering of scenes on AR devices, enhancing the user's immersion in the augmented reality environment.
  • Reduced computational load: By using sparse feature vectors, the method reduces the computational resources required for rendering, making it more efficient and enabling real-time rendering on AR devices.


Original Abstract Submitted

A method includes obtaining images of a scene and corresponding position data of a device that captures the images. The method also includes determining position data and direction data associated with camera rays passing through keyframes of the images. The method further includes using a position-dependent multilayer perceptron (MLP) and a direction-dependent MLP to create sparse feature vectors. The method also includes storing the sparse feature vectors in at least one data structure. The method further includes receiving a request to render the scene on an augmented reality (AR) device associated with a viewing direction. In addition, the method includes rendering the scene associated with the viewing direction using the sparse feature vectors in the at least one data structure.
