摘　　要：采用激光扫描技术建立运动员的运动模型,重构运动员的动作细节可改善训练水平。针对当前的Kernel重构方法维数较高,计算开销较大,提出基于最小二乘回归扩展算法的运动员三维人体模型重构方法。在人体骨架模型基础上进行运动员三维人体信息的激光扫描,视觉重建激光扫描采集的人体模型信息,采用线性内插方法将运动员三维人体激光扫描数据进行最小二乘拟合,运用最小二乘回归扩展方法实现运动员三维人体模型重构。最后通过测试进行了性能验证,结果表明,采用该方法进行运动员三维人体模型建立的效果较好,能对不同自由度的动作过程实现准确拟合,且计算复杂度较低。Using laser scanning technology to create athletes of 3D human body model, reconstruction of athlete＇ s action, improve the level of training, for a higher dimension of kernel reconstruction method calculated larger cost is proposed based on least squares regression algorithm for the athletes of three-dimensional human body model recon- struction method of expansion, the player 3D information of the laser scanning on the human skeleton model based, on laser scanning acquisition information of human model for visual reconstruction, using linear interpolation method will be athletes 3 D laser scanning data by the least square fitting, by least squares regression extension method to realize 3 D human model reconstruction of athletes. Finally the simulation test were performance verification, results show that the athletes 3 D human body model is established by using this method the effect is good, the action process of different de- grees of freedom to achieve accurate fitting, and has low computational complexity.
