发明名称 ADAPTIVE 3D REGISTRATION
摘要 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.

主权项 1. A method, comprising: obtaining a plurality of 3D models, wherein the first 3D model is composed of n entities; obtaining an estimated 3D registration among the plurality of 3D models; calculating an original error for each of the n entities based on the estimated 3D registration, therefore obtaining n original errors corresponding to the n entities; calculating a set of parameters for each of the n entities, therefore obtaining n sets of parameters corresponding to the n entities; calculating an adjusted error for each of the n entities based on the n original errors and the n sets of parameters, therefore obtaining n adjusted errors corresponding to the n entities; processing information related to the n entities based on the n adjusted errors.
