SYSTEMS AND METHODS FOR DETECTING A REFLECTION ARTIFACT IN A POINT CLOUD - A simplified explanation of the abstract
This abstract first appeared for US patent application 17731828 titled 'SYSTEMS AND METHODS FOR DETECTING A REFLECTION ARTIFACT IN A POINT CLOUD
Simplified Explanation
- The patent application describes a method for detecting reflection artifacts in a point cloud. - The method involves generating convex hulls to outline clusters of points in a depth image. - The first cluster of points originates from a point cloud, as does the second cluster of points. - The method determines if the second cluster of points is a reflection artifact by checking if a portion of its convex hull is enclosed within the first convex hull. - Additionally, the method compares the range of the second convex hull to the range of the first convex hull to make this determination.
Original Abstract Submitted
Systems, methods, and other embodiments described herein relate to detecting reflection artifacts in a point cloud. In one embodiment, a method includes generating a first convex hull for defining an outline of a first cluster of points in a depth image and generating a second convex hull for defining an outline of a second cluster of points in the depth image. The first cluster of points originates from a point cloud and the second cluster of points originates from the point cloud. The method includes determining whether the second cluster of points is a reflection artifact based on identifying if a portion of the second convex hull is enclosed in the first convex hull and a range of the second convex hull is larger than a range of the first convex hull.
