摘　　要：因非刚体三维运动图像在成像过程中,传感器区域的随机性对动作限制大、操作复杂,导致动作虚拟精度较低、图像质量差。为此,提出了多传感约束下三维运动图像连带动作高质量仿真。根据多传感器受重力加速度以及地磁场的作用,求解传感器从原始状态到运动当前状态的角度变化。根据变化数值对图像进行去噪,提取连带动作特征。在Vicon系统中计算连带动作空间位置,捕捉连带动作变换轨迹,将运动轨迹结果输入PAR系统,完成连带动作虚拟成像。仿真结果表明:该方法图像去噪效果较好,传感器响应时间始终低于0.52 s,传感器响应速度较快,连带动作轨迹误差始终低于0.045,动作虚拟仿真精度较高,能够有效提高三维运动图像质量。In the imaging process of non rigid 3D motion images,the randomness of the sensor area restricts the action greatly and makes the operation complex,resulting in low virtual accuracy of action and poor image quality.Therefore,a high quality simulation of 3D motion images and actions under multi-sensor constraints is proposed.According to the effects of multi-sensors on gravity acceleration and geomagnetic field,the angle change of sensors from the original state to the current state of motion is solved.According to the change value,the image is denoised and the joint action features are extracted.In Vicon system,the spatial position of joint action is calculated,the joint action transformation trajectory is captured,and the motion trajectory results are input into PAR system to complete the virtual imaging of joint action.The simulation results show that the proposed method has good image denoising effect,the sensor response time is always less than 0.52 s,the sensor response speed is fast and the associated motion trajectory error is always less than 0.045,the precision of virtual simulation is high,and the quality of 3D moving images can be effectively improved.
