Kinect™ and Intel RealSense™ D435 comparison: a preliminary study for motion analysis

Abstract

In this paper, we explore the feasibility to obtain the speed related to a person walking, using a new and unexplored RGB-D camera (Intel RealSense™ D435). For this, we obtain measurements for two devices, the Intel RealSense™and Microsoft Kinect™v2, which has been validated in previous studies. Finally, we compare the results obtained using both devices. This is an important exploration due to the wide variety of applications for this device and the obtained results. The results obtained suggest that this small and inexpensive device can be used to measure some spatiotemporal variables, for different use cases, like eHealth and analysis for high-performance athletes.
