利用飞行时间三维相机的非刚体形状三维重建

3D Reconstruction of Non-rigid Shapes Using One TOF Camera

  • 摘要: 针对目前基于飞行时间原理的三维测距相机捕获数据分辨率低、噪声大,无法直接使用的问题,提出一种非刚体形状三维重建算法.首先对不同角度拍摄的深度图像数据进行分割、去噪等预处理;然后对生成的网格序列进行刚体对齐、选取关键帧网格,以减少运动模糊和数据冗余的影响,并进行全局非刚体配准和网格变形来减少静物或人体扫描中的非刚体误差;最后进行泊松网格重建,得到较高质量的重建模型.实验结果表明,该算法显著提高了三维测距相机捕获数据的质量,扩大了其应用范围.

     

    Abstract: The captured data of a time-of-flight(TOF) camera can't be directly used due to its low image resolution and high noise level.Therefore,this paper presents an algorithm for 3D reconstruction of non-rigid shapes from one TOF camera.First,the captured data from different views are segmented and denoised.Second,the constructed meshes are roughly aligned with rigid alignment.Feature frames are selected to reduce motion blur and redundancy.Then the feature frames are further aligned with global non-rigid alignment to deal with misalignment of static objects with non-rigid errors and human bodies under low-frequency non-rigid deformation.Finally,a qualified mesh is generated using Poisson surface reconstruction.Our experiments show that the algorithm can improve the quality of captured depth data and extend the typical application of TOF cameras.
