Abstract

Motion capture systems are a must-have part of a modern research laboratory. The system has a wide area of applications such as movie, sport, medicine or experiments validations. The system provides accurate pose (both position and orientation) data and allows tracking several objects at the same time. The calibration process is a crucial part of using the system, which determines the further accuracy of tracking. This paper presents research struggling with this problem and describes a new approach to the camera placement process for the OptiTrack system, using the dedicated application programming interface and its features. The document discusses the general concept, shows the benefits of using it and confirms its usefulness. It helps to improve camera placement to ensure detection and reduction or elimination of "low tracking zones". The working tool is also presented.
