TIn Augmented Reality applications, registration between a virtual and a real world object is necessary. The registration
is needed for tracking video camera pose (position and orientation) with respect to the real world objects. In
existing vision-based augmented reality systems, marker-based technique is widely used approach to track the video
camera pose. In this paper, we present an analysis of marker-based tracking using ARToolKit. We investigate the
effect of marker size, distance between markers and camera, the speed of marker with respect to camera, relationship
between marker size and distance, the brightness and contrast level of a camera on tracking a single marker.
Experiments were conducted to produce the analysis of these factors.
