摘要: 实现了一种通用的从序列影像中获取任意的人体运动的软件系统。该系统基于一个普通的三维人体模型,该模型的尺寸可以改变,以与影像中的人体相匹配。该系统不需要特殊的设备和标志,对序列影像也没有特殊的要求,可以处理任意的人体运动,操作简单,适合人体运动信息获取的需要。Abstract: This paper developes a general software to acquire arbitrary motion from a video sequence. A general 3D articulate human model with changeable size, color and surface shape is prepared. This model is then driven either automatically or manually to match with the moving body in the consecutive image frames. This matching starts from key frames that contain key poses. A specific orientation interpolation is used to get the motion status in in-between frames and finally a smooth motion is obtained. This method is suitable for personal use to meet wide needs of human motion acquisition.
