A personalized human body modeling method with high precision bas ed on single Kinect is proposed. Firstly, the high-precision point cloud of a human head usi ng single Kinect is obtained. Then, the point cloud is preprocessed based on maintaining the accuracy of the head. Finally, by employing the hierar chical compactly supported radial basis function (CS RBFs), the sampled point cloud is fitted with the existing human body to get 3D human body model. Simulation results show that the proposed method can enhance accuracy and speed of hu man body modeling.
