Interactive Method and Experiment in 3D Human Motion Data Abstraction
-
摘要: 提出使用人机交互的方法,通过加工处理现场录像资料,并与计算机图形学技术相结合,整体提取人体的三维运动数据.针对提取过程中的关键环节——数据提取人员,进行了姿态识别精度实验.实验的样本采用计算机图形、图像以及动态画面,实验结果表明识别精度良好.最后介绍了对运动数据的加工转化过程.Abstract: Interactive method is raised in this paper to abstract three dimension human motion data from video by combining human distinguishing and computer graphics simulation. The approach to abstract human three dimension data is a whole posture, not a single joint, and which is different from the manual approach. A series of experiments are taken to test human distinguishing which is the key in the interactive method. Graphic, photo and video are used as samples in the experiment. The result shows that human distinguish posture well. In the bottom of this paper, the procedure of data processing is introduced that how to compute velocity and acceleration of each joint angle and each limbs.
