基于虚拟现实技术的移动端交互性动画自主生成方法研究

Research on the method of mobile interactive animation self generation based on Virtual Reality Technology

当前移动端动画自主生成方法具有互动性差、准确率低等问题,提出一种基于虚拟现实技术的移动端交互性动画自主生成方法。设计了移动端交互性动画自主生成流程,按照执行流程完成功能模块划分。按照动画需求对动画节点坐标进行严格标定,以提高动作的生动性。对运动进行捕捉时,在不同标记点固定反光球,针对关键部位会在同一标记点附近安装多个反光球,进行标记点跟踪。对摄像机坐标系进行归一化处理,将工作坐标和摄像坐标转换,得到三维任务根节点空间坐标系与主要节点空间坐标系位置,把重要节点位置转换成通过连续动画帧构成的运动序列,产生三维动画。把已有三维数据映射至三维任务模型中,通过Maya软件完成动作加载,生成动画场景。并且引入线性混合蒙皮算法避免裂缝。经验证,所提方法互动性好,准确率高。

At present,there are some problems in the autonomous generation of mobile animation,such as poor interaction and low accuracy.The mobile interactive animation autonomous generation process is designed,and the functional modules are divided according to the execution process.According to the requirements of animation,the coordinates of animation nodes are strictly calibrated to improve the vividness of the action.When capturing the motion,the reflective ball is fixed at different mark points,and multiple reflective balls are installed near the same mark point for key parts to track the mark points.The camera coordinate system is normalized,and the work coordinate and camera coordinate are transformed to obtain the space coordinate system of the root node and the space coordinate system of the main node of the three-dimensional task.The important node position is transformed into the motion sequence composed of continuous animation frames to generate the three-dimensional motion picture.The existing 3 D data is mapped to the 3 D task model,and the action loading is completed by Maya software to generate the animation scene.The linear hybrid skin algorithm is introduced to avoid cracks.The proposed method is proved to be interactive and accurate.
