Classification: CPC H | IPC H

Claim 0:
1. A method of coding point cloud data, the method comprising:
determining height values of points in a point cloud;
coding a data structure including data representing a top threshold and a bottom threshold;
coding data representing a midpoint between the top threshold and the bottom threshold;
coding data representing a distance from the midpoint to the top threshold and the bottom threshold;
classifying each of the points into either a set of ground points or a set of object points according to the height values, including:
classifying points having height values below the threshold into the set of ground points; and
classifying points having height values above the threshold into the set of object points; and
coding the ground points and the object points according to the classifications.
