SYSTEMS AND METHODS FOR ADDING PERSISTENCE TO SINGLE PHOTON AVALANCHE DIODE IMAGERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240112605 titled 'SYSTEMS AND METHODS FOR ADDING PERSISTENCE TO SINGLE PHOTON AVALANCHE DIODE IMAGERY

Simplified Explanation

The system described in the patent application allows for the addition of persistence to SPAD (Single-Photon Avalanche Diode) imagery by capturing multiple image frames using a SPAD array and pose data associated with each frame using an IMU (Inertial Measurement Unit). The system then calculates a persistence term based on the pose data and generates a composite image using the image frames, pose data, and persistence term.

  • SPAD array used to capture multiple image frames
  • IMU used to capture pose data associated with each image frame
  • Persistence term calculated based on pose data
  • Composite image generated using image frames, pose data, and persistence term

Potential Applications

The technology could be applied in fields such as:

  • Augmented reality
  • Virtual reality
  • Robotics
  • Autonomous vehicles

Problems Solved

The system addresses the following issues:

  • Enhancing image quality in low-light conditions
  • Improving image stabilization
  • Enhancing motion tracking capabilities

Benefits

The technology offers the following benefits:

  • Enhanced image quality
  • Improved motion tracking
  • Increased accuracy in pose estimation

Potential Commercial Applications

The system could be utilized in various commercial applications such as:

  • Surveillance systems
  • Medical imaging devices
  • Gaming technology
  • Navigation systems

Possible Prior Art

One possible prior art for this technology could be the use of IMUs in conjunction with image sensors for image stabilization in cameras and smartphones.

Unanswered Questions

How does the system handle occlusions in the captured image frames?

The patent abstract does not mention how the system deals with occlusions in the captured image frames. This could be a crucial aspect to consider, especially in applications where objects may obstruct parts of the scene.

What is the computational complexity of generating the composite image?

The abstract does not provide information on the computational complexity of generating the composite image. Understanding the computational requirements of the system could be essential for assessing its feasibility in real-time applications.


Original Abstract Submitted

a system for adding persistence to spad imagery is configurable to capture, using a spad array, a plurality of image frames. the system is configurable to capture, using an imu, pose data associated with the plurality of image frames. the pose data includes at least respective pose data associated with each of the plurality of image frames. the system is configurable to determine a persistence term based on the pose data. the system is also configurable to generate a composite image based on the plurality of image frames, the respective pose data associated with each of the plurality of image frames, and the persistence term. the persistence term defines a contribution of each of the plurality of image frames to the composite image.
