Abstract:
Rigid registration is an important step in 3D scanning and modeling of manufactured objects that are generally
composed of a combination of basic geometric primitives such as planes, spheres, cylinders, etc. In this
paper, an efficient and robust method is proposed to align two basic geometric primitives. The transformation
between two primitives is found by minimizing the parameter error between primitive correspondences. The
approach applies an interior-point method and a new objective function to achieve good results. Compared
to previous primitive-based alignment approach proposed by Rabbani et al. (Rabbani et al., 2007), the presented
approach achieves better results in terms of convergence and accuracy. Finally, the proposed method is
used in various applications such as data completion and primitive-based registration for quality control and
inspection.
