Title:
METHOD AND APPARATUS OF ENCODING/DECODING POINT CLOUD CAPTURED BY A SPINNING SENSORS HEAD
Document Type and Number:
WIPO Patent Application WO/2023/273537
Kind Code:
A1
Abstract:
There is provided methods and apparatus of encoding/decoding a point cloud captured by a set of sensors. The encoding method obtains a list of ordered points of the point cloud by ordering the points according to a lexicographic order based on azimuthal angles and sensor indices associated with points of the point cloud; obtains a next point following a current point in the list of ordered points and having an order index different of an order index of the current point, and obtainsa numberof duplicated points equals to a number of points following the current pointthat have an order index equals to the order index of the current point; encodes the number of duplicated points and encodesan order index difference representing a difference between the order index of the next point and the order index of the current point.
