基于单目摄像机的运动员姿态计算

Research for Computation of 3d Pose in Monocular Video

运动员姿态的计算是非常困难的并且有很多应用。在本文中,我们主要针对运动员身体倾角,提出了一种基于单目摄像机的几何计算方法。首先,利用针孔模型对场景进行3d重建。其次,利用运动员的臀部位于运动员脚部轨迹在相应的脚部点处的法平面的先验知识,计算运动员身体与运动场地的夹角。在本文的最后,给出了实验的结果,结果表明方法是比较实用的,能满足人体运动分析的基本要求。

Human pose measurement is difficult and has many applications. In this paper, we provide a novel approach for athlete pose measurement using geometric method with some prior knowledge, and only use one camera. Firstly, using pinhole model, we construct the 3d model of the scene. Then, by assuming that the athlete＇s rear is in a normal plane of the ground plane, we calculate the angle between the athlete and the ground plane. In the last, we demonstrate the system which perform these tasks and provide some experimental results.
