In this paper, we set up a physical rehabilitation assistant system based on skeleton detection with Kinect produced by Microsoft. First of all, the users do not have to install the detectors on the exercise equipment. Secondly, they pay a little extra expensive to buy the rehabilitation equipments with Kinect using skeleton detection technique. In this study, we build a normalized three-dimensional Cartesian coordinates location of correct postures under OpenNI system. We find out 15 human skeleton joints with three dimensional coordinates and calculate the feature values, than we use support vector machine (SVM) as classifier to define the accuracy of posture. Finally, the system can judge the correct degree of user’s postures.
