Abstract

A method of merging 3D meshes includes receiving a first mesh and a second mesh; performing spatial alignment to register the first mesh and the second mesh in a common world coordinate system; performing mesh clipping on the first mesh and the second mesh to remove redundant mesh vertices; performing geometry refinement around a clipping seam to close up mesh concatenation holes created by mesh clipping; and performing texture blending in regions adjacent the clipping seam to obtain a merged mesh.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit and priority of U.S. Nonprovisional Patent Application Serial No. 15 / 467,851, filed March 23, 2017, and claims U.S. Provisional Patent Application Serial No. 62 / 322,081, filed April 13, 2016 rights and priorities. The entire contents of the aforementioned patent applications are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates generally to computerized three-dimensional (3D) mesh reconstruction, and more particularly to an automated method for merging two or more 3D textured meshes into one textured mesh. Background technique [0004] Textured meshes are a common representation of 3D geometric shapes, which are widely used in many graphics applications including virtual reality, scientific visualization, 3D photography, 3D games, etc. Various techniques have been introduced to reconstruct meshes from 3D scans. However, creat...
