dc.description.abstractOptical tracking systems predominantly rely on spherical retro-reflective markers, requiring a minimum of three fiducials to achieve a full six-degree-of-freedom (6D) pose estimation. Despite the potential benefits of a single non-spherical fiducial for 6D pose estimation, this approach has received limited attention in the literature. This study investigates the feasibility of nonspherical retro-reflective markers, specifically tetrahedral markers, as alternatives to spherical fiducials. Using Blender for simulation and digital post-processing, stereo images of both spherical and tetrahedral markers were generated. The standard marker tracking is adapted to use the tetrahedrons corners instead of sphere centers. Results indicate that while spherical markers provide slightly more precise tracking in the simulated scenario, tetrahedral markers offer advantages in practical applications, such as an enhanced range of motion. These findings suggest that non-spherical markers warrant further exploration for their potential to improve optical tracking systems in real-world settings.en_US
