Abstract

Team sports coaches are always looking for tools to help them in their coaching routines. They are more toward statistical analyses and quantitative judgements like never before. Decades have passed, manual counting of athletes' attempts and blocks are no more practical for today's fast-paced team sports. In recent years, various commercial motion capture systems have been developed with scaring price tag since considered as hi-tech and exclusive. This work is established to document the elementary procedures to perform a motion capture system and analysis as a team sports strategic tool. Netball is used as case study in order to describe the steps involved for clarification. To further simplify the raw to simulated data process, a set of magnetic-driven points on a scaled-down court is used to represent players' movements during a match. A single camera located at the top centre of the court was used throughout the motion capture process. The full area covered 60 fps digital video was then converted into three-dimensional matrix consist of RGB colour values via a matrix based programming platform. 'Players' from the competing teams were distinguished based on this colour differences. Interpolation methods were used to quantify players' movements from the pixel data before it was then interpreted as transient simulation, motion analyses, statistics and strategic implications. In this work, the data was represented as a tailed displacement of all players, velocity and acceleration of selected players together with sample analyses. This work is expected to give an overview on how a motion capture system is manipulated in team sports such as netball. The same principle can be implemented for other team sports with proper arrangements and modifications
