Three-dimensional modeling

A modeling apparatus , the modeling apparatus comprising:

• processing circuitry ;
• and
• a memory, the memory containing instructions executable by the processing circuitry, wherein the modeling apparatus is configured to perform a method for producing a reduced point cloud comprising an object of interest (OOI ) from an original point cloud comprising the OOI, the method comprising:
• obtaining the original point cloud, the original point cloud comprising a set of points, each point having a location in a three-dimensional (3D) space;
• obtaining a set of N images, each of the N images comprising an image of the OOI from a unique position relative to the OOI;
• for each one of the N images, defining an area of interest in the image that includes the OOI, thereby defining N areas of interest;
• for each point included in the set of points, determining, for each one of the N areas of interest, whether the point is located in the area of interest;
• for each point included in the set of points, determining a first metric for the point based on the total number of the N areas of interest in which the point is determined to be located;
• and
• for each point included in the set of points, determining whether or not to include the point in the reduced point cloud based on the first metric for the point.
