Kinematic Analysis of Hurdle Clearance using a Mobile Device

摘要

This paper presents a human motion tracking method using a mobile device. The proposed method may be used as a tool to measure hurdle clearance kinematic parameters and help coaches to evaluate the athlete's technique. The video recordings were made under simulated starting conditions of a 100 m women hurdle race. Kinematic parameters were estimated based on an analysis of images sequence from a mobile device. The images were recorded on a HTC M8s smartphone with a resolution of 1920×1080 pixels and with a frequency of 30 Hz. The system was tested on two mobile development platforms and three image sequences. The proposed method does not use any markers, special clothes or other estimation support techniques. The analysis conducted showed that the smallest errors were calculated for the height of centre of mass, while the biggest errors were observed for the bending angle of the knee of the trail leg.
