Depth data based capture of human movement for biomechanical application in clinical rehabilitation use

Abstract

In this article current development works of a 3D human movement analysis system are presented which aims to meet the demands for the routine application in the clinical everyday life. The sensory base of the system is a depth camera. Important considered criteria are: easy integration in an available clinical environment, small set-up time at the patient and quick realization of the measurement as well as the exactness of the measuring results. Especially the small setup time enforces a system which is free of marker usage. The functionality of the developed system is demonstrated on a gait therapy robot (see figure 1), though not being limited to it. The resulting gait parameters show similar characteristics to reference gait data.
