Unconstrained Registration Algorithm for Multiple View 3D Scanned Data

Cheng Xiaosheng Cui Haihua Liao Wenhe Dai NingNanjing University of Aeronautics and Astronautics,Nanjing,210016  
A two-stage algorithm for registering 3D scans obtained from multi-view of an object was described.First step,two similar point clouds was selected from overlap regional.According to the principle of space coordinates transform,a new N-edge algorithm was used for pre-registration and acquire the transform matrix parameters of pre-registration.Then,the improved ICP(iterative closest point) algorithm was used to registration accurately for the initial positional sampling point clouds.This second step integrated the merits of traditional iterative closest point distance function,set multi-level thresholds for the termination of iterative and resample the corresponding point level by level.The two-stage technique has advantages in terms of accuracy,efficiency and global minimum convergence.Experiments show that this two-stage algorithm has the advantage of perfect performance and high precision,it is suitable for special 3D measurement registration field without coded points and no mechanical turntable.
