  Abstract

In this study, we introduce the implementation of a biomechanical analysis system that calculates the torque applied to the human lower limbs using a depth camera and force sensing resistors (FSR). The FSR matrix measures the vertical component of the ground reaction force and the center of pressure acting on the human body on the ground. Kinect, a representative depth camera, obtains the three-dimensional coordinates of the joint center. By measuring the position of the spherical markers attached on the FSR matrix using kinect, the coordinate system between the two sensors is aligned. Biomechanical analysis is performed using information measured by FSR and kinect, and the subject’s height and weight. We demonstrate the feasibility of the implemented system through the upright standing posture analysis experiment. This system is the first study that combines FSR and kinect to perform biomechanical analysis. It is expected that it will be able to replace the existing high cost system in limited applications such as upright standing posture analysis.
