运动捕捉数据重用方法的研究

Research on Technologies of Motion Capture Data Reuse

自从运动捕捉技术被引入计算机动画制作领域之后,以其真实准确的优点得到了迅速的推广,如今在人们生活的各个领域都能够看到运动捕捉技术的身影,然而该技术同样存在一些缺点,其中最主要的缺点就是运动捕捉的成本十分昂贵,因此如何更好的重用已有的捕捉数据成为计算机图形学研究的一大热点。本文将对现有的运动捕获数据重用技术进行详细的剖析和比较。我们这里所说的重用技术是指在只需要较少的人工交互的基础上对运动数据的重新使用。按照不同的原理和处理方法我们将这些运动数据重用技术分成了三大类:对运动捕捉数据的直接重用,对运动捕捉数据的间接重用和直接与间接相结合的重用方法。并对各种代表技术进行了论述,分析了这些技术的优劣和可能的改进方法。

With advantages of realism and accurcy, the Motion Capture technology achieves great rapid promotion. Since it has been introduced to computer animation, and we can see Motion Capture technology in many field of people＇s life. However, the technology also has some shortcomings, the most important one of Motion Capture is the high cost. So how to effciently reuse existing motion capture data has become a major focus in computer graphics research. This paper will analysis and compare the reuse technology of motion capture data in detailed. The reuse technology we talking about here refers to reusing motion data which only need much less artificial interactive. According to the principles and processing methods, we will divide the motion reusing into three major categories：the direct reuse of Motion Capture data; the indirect reuse Motion Capture data and the hybrid methods of the former two. we will mainly emphasize on various representative techniqes, and analyze their performance or possible improvements.
