Means of matching 2D motion vector fields in a render, match, and refine iterative 3D scene model refinement system so as to attain directed hierarchical convergence and insensitivity to color, lighting, and textures

摘要

This application concerns an enhancement of the render, match, and refine (RMR) method [0002] for 3D scene model refinement. A method is provided that allows for the directed refinement of camera and geometry associated parameters of the 3D scene model in a manner that is independent of lighting, color, and texture. The method is based on the matching of a rendered motion vector field to a motion vector field estimated from a recorded video stream.
