Abstract: Symmetry is an important attribute for most natural objects.Alignment of 3D model is a key preprocess step for 3D model retrieval.For this problem,an approach to align 3D model using partial symmetry was proposed.First,CPCA coordinate planes of a 3D model are computed to establish the model’s initial pose.Then a new measure,which is called partial symmetry length ratio (PSLR),is introduced to judge the model’s partial symmetry plane.If the model has more than 2 planes,the pose with maximal PSLR is the estimated pose.Otherwise,moment balance is used to estimate the model’s final pose by computing area instead of mass.The algorithm takes into account both the symmetric nature of the model and the asymmetric model.The validity is showed by results demonstration.
