交互标记跟踪的三维动态数据对齐

摘要

Aiming at that 3D animation feature point matching causes wrong correspondence,this paper proposed interactive mark and motion tracking to improve the reliability and stability of feature point atching.Firstly,the algorithm marks the point on some specified frames.Then,it gets the positions on other frames through motion tracking and optimal prediction window.Finally,the tracking points are used to build isometric bipartite graph for final correspondence.In experiment,the algorithm can get better alignment accuracy than existing algorithms.%针对三维动态数据特征点匹配所导致的错误对齐问题,采用交互标记和运动跟踪来提高特征点匹配的可靠性和稳定性.首先,对三维动态数据特定帧交互标定特征点;然后,通过运动跟踪和最优预测窗口得到标定特征点在其他帧上的位置;最后,以跟踪匹配的特征点为约束条件来构造等距二分图,得到三维动态数据紧密对齐结果.实验结果表明,所提算法的对齐准确率高于已有算法.
