Abstract

The aim of this bachelor thesis is to explore which criteria limit the precision of an infrared optical tracking system, and how a certain degree of precision can be guaranteed. Further- more a tool is developed that enhances an existing tracking system software with the capa- bility of setting and monitoring the tracking accuracy. The main task in the first half of this project is to find out which parameters determine and influence infrared optical tracking. After an intense brainstorming on parameters that are relevant for tracking accuracy, all these items are categorized and a preliminary estimation of the relevance of each of them is made. Next, some of these criteria are extensively assessed using the infrared tracking system of the chair this thesis is done at. Therefore procedures for measuring and evaluating scientific data have to be established first. For example, scripts and interfaces have to be created in order to establish data exchange between the tracking system and visualization tools. In the second half of this project it will be evaluated, if and how the knowledge and results of the previous study can be used for monitoring or optimization of tracking accuracy. To demonstrate this, a precision monitoring tool shall be developed for A.R.T. GmbH, manu- facturer of the before mentioned infrared optical tracking system.
