Application of a Vision-Based Single Target on Robot Positioning System
Sensors, 2021 In this paper, we propose a Circular-ring visual location marker based on a global image-matching model to improve the positioning ability in the fiducial marker system of a single-target mobile robot.

A method for predicting marker tracking error
, 2007 Many Augmented Reality (AR) applications use marker-based vision tracking systems to recover camera pose by detecting one or more planar landmarks. However, most of these systems do not interactively quantify the accuracy of the pose they calculate ...

Fiducial marker guided prostate radiotherapy: a review [PDF]
The British Journal of Radiology, 2016 Image-guided radiotherapy (IGRT) is an essential tool in the accurate delivery of modern radiotherapy techniques. Prostate radiotherapy positioned using skin marks or bony anatomy may be adequate for delivering a relatively homogeneous whole-pelvic radiotherapy dose, but these surrogates are not reliable when using reduced margins, dose escalation or ...

Multiple Projector Camera Calibration by Fiducial Marker Detection
IEEE Access, 2023 Projection mapping has been used for various purposes in everyday situations. A key step in projection mapping is to project images and videos without distortion through calibration, which is typically performed manually.

Cracking the Code: Genotype–Phenotype Correlation Models in Sarcoglycanopathies
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Sarcoglycanopathies are among the most severe limb‐girdle muscular dystrophies (LGMD), though milder presentations have been described. These diseases are primarily caused by missense variants, but the limited predictability of their effect on protein maturation, complex formation, and transport has hindered reliable genotype ...
