本文介绍了一种物理上精确的脊柱模型及其应用，以估计三维脊柱姿势从正面和侧面的意见，一个人的身体由两个传统的视频摄像机。在我们的方法中，每个部分的粗略位置估计使用一个简单的模型适用于图像。基于简单模型拟合过程中获得的特征，计算作用在精确模型上的力。通过在这些力下使模型变形来估计精确的姿态。由于作用在椎间盘上的力很容易计算，所提出的方法是有用的，为用户提供良好的建议，以实现健康和安全的身体姿势。从应用于实际人体图像的实验结果，我们证实了所提出的方法估计三维姿态的人体脊柱合理。
This paper describes a physically precise spine model and its application to estimate three dimensional spine posture from the frontal and lateral views of a human body taken by two conventional video cameras. In our method, rough position of each part is estimated by using a simple model applicable to images. Based on the obtained features from the fitting process of the simple model, the forces acting on the precise model are computed. The precise posture is estimated by deforming the model under these forces. Since the forces acting on intervertebral disks are easily calculated, the proposed method is useful for giving good suggestions to a user to achieve healthy and safe body posture. From the experimental results of application to actual human images, we confirmed that the proposed method estimated 3D posture of the human spine reasonably.
