【摘要】 为了实现非刚体的三维重建,本文提出了一种基于轨迹基的三维非刚体线性重建方法.利用非刚体的运动轨迹构成一个低维子空间,并由一组Haar小波基线性表示,从而线性地实现三维非刚体的重建.由于该Haar小波基可以事先定义,求解的未知数大大减少,并且使三维非刚体的重建转化为线性求解问题,提高了算法的鲁棒性.仿真实验和真实数据实验表明,该方法能够有效地实现非刚体的三维重建.更多还原

【Abstract】 This paper presents a linear reconstruction method for the 3D non-rigid based on a trajectory basis.Reconstruction of the 3D rigid can be linearly realized based on the fact that the trajectories of a non-rigid span a low-dimensional subspace that can be spanned by a Haar wavelet basis. Because the wavelet basis can be predefined, the solved parameters are deduced and the 3D non-rigid reconstruction becomes a linear solution,which can improve the robustness of the algorithm. Experiments with both simulated and real data show that the presented method can efficiently reconstruct the 3D non-rigid.更多还原
