Real-time, fully interactive, virtual sports and wellness trainer and physiotherapy system
A telehealth training system is provided which employs a three-dimensional camera programmed for capturing image data associated with an exercise program performed by a user. A computer-implemented body pose analysis and scoring module analyzes and scores body poses of the user while the user performs the exercise program. The analysis and scoring module may calculate scores in response to reference data related to at least one exercise prescribed for the user, and then compare processing results to the reference data. A feedback module may be included in the system which is programmed for creating and animating an avatar in response to the processing results of the analysis and scoring module. In certain aspects, the analysis and scoring module may be programmed for using a voxel basis function (VBF) technique in connection with performing pose matching analysis in association with the user performing the exercise program.
