METHOD AND APPARATUS OF ENCODING/DECODING POINT CLOUD GEOMETRY DATA CAPTURED BY A SPINNING SENSORS HEAD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18553816 titled 'METHOD AND APPARATUS OF ENCODING/DECODING POINT CLOUD GEOMETRY DATA CAPTURED BY A SPINNING SENSORS HEAD

    • Simplified Explanation:**

The patent application describes methods and apparatus for encoding and decoding a point cloud representing a physical object, where each point in the cloud is associated with a residual radius. This residual radius is the difference between the actual radius of the point from a reference point and a predicted radius.

    • Key Features and Innovation:**
  • Encoding and decoding of the sign of the residual radius based on previously encoded non-zero residual radii.
  • Utilization of entropy encoding to efficiently represent the data.
  • Prediction of the radius of each point in the point cloud.
    • Potential Applications:**
  • 3D modeling and visualization.
  • Augmented reality applications.
  • Autonomous navigation systems.
  • Robotics and automation.
    • Problems Solved:**
  • Efficient encoding and decoding of point cloud data.
  • Accurate representation of physical objects in a digital format.
  • Reduction of data storage requirements.
    • Benefits:**
  • Improved data compression.
  • Enhanced accuracy in representing physical objects.
  • Increased efficiency in data processing.
    • Commercial Applications:**
  • "Efficient Point Cloud Encoding and Decoding Technology for 3D Modeling and Visualization"
    • Prior Art:**

No prior art information available at this time.

    • Frequently Updated Research:**

No frequently updated research relevant to this technology at this time.

    • Questions about Point Cloud Encoding and Decoding:**

1. How does this technology improve data compression compared to existing methods? 2. What are the potential limitations of using entropy encoding for point cloud data?


Original Abstract Submitted

There is provided methods and apparatus of encoding/decoding a point cloud representing a physical object, each point of the point cloud being associated with a residual radius between a radius responsive to a distance of the point from a referential and a predicted radius. The method entropy encodes/decodes the sign of the residual radius associated with a current point of the point cloud based on the sign of a previously entropy encoded/decoded non-zero residual radius associated with a previous point.
