基于骨骼信息的虚拟角色控制方法
Avatar control method based on skeleton data
摘要
Abstract
Since the current avatar control methods based on rotation matrix in motion capture methods have shortcomings in action accuracy and real-time property,and the anti-interference ability for illumination,a new avatar control method based on quaternion vector of skeleton data is proposed.First,the displacements of joints and the changes of the angles between joints during the movement are calculated and recorded based on the skeleton data captured by the Kinect.Then the rota-tion angle of bone joints are calculated according to the motion data in successive frames and are transformed to quaternion vectors.Finally,with the forward kinematics principle,the avatar gesture is accomplished and real-time feedback from root joint according to the body movements.Theoretical analysis and simulation results show that the method performed better on gestures accuracy,decrease of angle errors,straight real-time preview,and robust performance on light disturbance com-pared with avatar control methods based on rotation matrix.关键词
