Planar fiducial markers: a comparative study

Virtual Reality, 2023
Fiducial markers are a cost-effective solution for solving labeling and monocular localization problems, making them valuable tools for Augmented Reality (AR), robot navigation, and 3D modeling applications. However, with the development of many marker detection systems in the last decade, it has become challenging for new users to determine which is ...

Sonographic-guided percutaneous fiducial marker implantation of hepatic malignancies for Cyberknife radiation therapy: Evaluation of safety and technical efficacy

Journal of Medical Sciences, 2015
Background: CyberKnife radiation therapy has a widely used system in the treatment of extracranial lesions. Implanting gold fiducial markers around a tumor is an important procedure for the planning and aiming of CyberKnife radiation therapy.

Computed tomography based evaluation of prostatic fiducial marker migration between the periods of insertion and simulation

Urology Research and Practice, 2019
Objective: The aim of this study was to determine whether significant fiducial marker migration occurs between the periods of prostatic marker insertion and computed tomography (CT) performed for radiotherapy planning and if a waiting period is necessary.

Design, Detection, and Tracking of Customized Fiducial Markers [PDF]

IEEE Access, 2021
Fiducial markers such as QR codes, ArUco, and AprilTag have become very popular tools for labeling and camera positioning. They are robust and easy to detect, even in devices with low computing power. However, their industrial appearance deters their use in scenarios where an attractive and visually appealing look is required.
