Human motion data reconstruction using quaternion spline interpolation
摘要
Abstract
To obtain smooth keyframes-based human motion animation, an interpolation algorithm of quaternion spline is presented, which constructs a smooth interpolation curve on the 4D sphere by using ideas of spline.An iterative method is uti lized to compute control points of quaternion spline,a collection of keyframes as initial approximation is selected in order to minimize reconstructed error and maximize the convergence.A segment Bezier curve is computed through four control points of quaternion spline, as a result that a quaternion spline is a composite curve consisting of several Bezier curve segments.The de Casteljau algorithm is used as a method of evaluating quaternion spline to interpolate.Experimental results show the present ed algorithm can obtain real-time smooth interpolation, and the reconstructed motion is closely to the ideal.关键词
