RESOLUTION ADAPTIVE MESH THAT IS GENERATED USING AN INTERMEDIATE IMPLICIT REPRESENTATION OF A POINT CLOUD

摘要

A method for generating a resolution adaptive mesh for 3-D metrology of an object includes receiving point cloud data from a plurality of sensors. The point cloud data from each sensor defines a point cloud that represents the object. Each point cloud includes a multiplicity of points and each point includes at least location information for the point on the object. The method also includes determining a resolution of each sensor in each orthogonal dimension based on a position of each sensor relative to the object. The method additionally includes generating a surface representation of the object from the point clouds using the resolutions of each sensor. The surface representation of the object includes a resolution adaptive mesh corresponding to the object for metrology of the object. Generating the surface representation includes fitting a mesh to the point clouds using an intermediate implicit representation of each point cloud.
