摘要(Abstract)：
针对基于自标定的三维人物图像动态重构方法不能准确获取人物运动形态的三维位置,重构结果存在较高的偏差的问题,提出基于多媒体技术的三维人物图像动态重构方法,采用单目图像重构算法完成人体三维姿态重构。对多媒体技术中单摄像机拍摄的单目人体运动图像进行重构时,首先基于人体树状模型,采用基于部件检测器的二维肢体检测算法完成人体二维肢体检测;再采用基于关节点图像坐标的三维姿态重构算法,依据人体二维姿态检测结果,通过预测关节点反投影误差的退火粒子滤波算法完成人体三维姿态的跟踪,实现三维人体图像动态重构。实验结果说明,所提方法可准确实现三维人物图像动态重构,具有较高的重构精度和效率。
