Evaluating Athletic Performances with a Real Time Location and Tracking System

Abstract:

The precision in localization of the UBISENSE Real Time Location System was assessed for evaluating the possibility of using the system in the detection of movements and position of athletes on the field during sport performance. The system was implemented in an indoor lab space measuring 11 by 7 meters. Four sensors were installed on the roof at a height of 3 meters above floor. Various sampling rates were used with a single location tag. UBISENSE is using UWB localization technology based on the triangulation of time of arrivals of UWB pulses at the different antenna sensors. Precision varied in position and speed determination being position resolution in the range of 15 to 50 cm while speed precision was in the figure of 6% at slow actual speed of 0.18 m/s up to 20% at fast speed of 1 m/s. This was mainly due to sampling frequency in the location system. In conclusion, as long as speed of the athlete is not at stake, the position can be measured with quite good resolution and sampling frequency so to permit the evaluation of sport performances of the athlete during the exercise or activity. A very attractive feature of the system is that the athlete must be tagged with a very low-weight and quite comfortable active tag which, on the contrary to video tracking systems, doesn’t need to remain in the field of view.
