Remote Physical Therapy: Requirements for a Single RGB Camera Motion Sensing

SGS20/214/OHK3/3T /37 ”Active learning of time series models”, the project No.FV −20696 “Personal health monitoring and assistive systems” The aim of this work is to assess the minimal technical requirements for using a simple RGB camera for motion sensing in a standard home environment. We experimentally verify the recording requirements for subsequent motion analysis. Our work contributes to the development of physical telerehabilitation without the need to use special HW and thus enable telerehabilitation for the general public, which is especially important during the COVID-19 lockdown. We have found out that such a system can work surprisingly well even with a low-cost camera in poor recording conditions and slow 3G internet connection.
