Use of the Infrared Based Motion Capture System AS 200 in Sport Science

In the field of optical measurement systems there are two main possibilities. On the one hand collecting data by using normal standardized video cameras is very popular. On the other hand measurement systems based on infrared cameras become more and more important. Comparing these two optical measurement systems there are different features in quality making them either attractive or not. Regarding video-systems, the recording of the movement is very simple but the analysis is very time-consuming. In contrast to the normal video camera-systems the infrared-based systems have the advantage to provide kinematic parameters in real-time, making it very interesting for scientific research as well as coaches. The AS 200 (LUK Otronic) for instance is an active infrared-based measurement system which consists of three infrared cameras fixed on a beam. Therefore, it is possible to install this system very fast and simply. Possible fields of application seem to be: biomechanical analysis of sport movements and medical researches. This study will present an evaluation and different options how to applicate the AS 200, especially fast movements in sport.
