Title:
ADAPTIVE 3D REGISTRATION
Document Type and Number:
WIPO Patent Application WO/2014/178049
Kind Code:
A3
Abstract:
An adaptive error measure, weights and sampling criterion for 3D registration algorithms. Adjusting a sampling criterion for each entity of the 3D model by a factor controlled by a value associated with the expected error for the particular entity, derived from parameters such as accuracy and local 3D model density. Similar adjusted error measure that evaluates the quality of the 3D registration result at different regions of the 3D models, and an adjusted weighting scheme, that assign weight for each entity of the 3D model, are also discussed. In an iterative 3D registration algorithm, adjusted outlier detection criterion after each iteration according to the convergence rate of the algorithm is presented, therefore allowing iterative 3D registration algorithms to escape areas of slow convergence rate and local minima.
