Research On Gait Model Of Virtual Human For Costume Show

A Virtual human is a digital representation of various characteristics (including: geometry, behavior, perception, emotion, psychology and etc.) of the real human beings in the virtual world. It presents the characteristics of the real human into digital reappearance in a highly precise manner. The mostly trivial behavior of human being is walking, so research on universal gait motion model is ordered sharply, especially in the foreland research field of virtual customs design and exhibition.Specifically, we make use of investigations on both fields of biomechanics and robotics to research on gait model of virtual human for costume exhibition. In all, we make the following contributions:1. To establish motion representation method based on sagittal elevation angle,2. To map sagittal elevation angle to joint angle;3. To parameterize the gait, and associate the high-level controller and low-level generator.Our system makes great efforts to accomplish these goals by integrating procedural animation method with data-driven method. By controlling some gait parameters our system will achieves gait motions with disparate style.After introducing some backgrounds and the state of art of gait motion, we introduce motion representation method of gait based on sagittal elevation angle in Chapter 2. The characteristics of biomechanics in the cyclogram indicate that this sagittal elevation angle matches the requirement of gait motion model of virtual human. Chapter 3 introduces the method to achieve the gait dataset, and map sagittal elevation angle to joint angle. Chapter 4 classifies the gait parameters into high level controlling parameter and low level generating parameter, and elaborates them. Chapter 5 shows our effort about virtual costume exhibition at nearly two years and put a construct forward as key module in next version. Finally, we conclude this thesis and discuss some directions for future work.
