This study conducts a comparative analysis of two types of augmented reality-assisted surgical navigation systems designed for orthopedic procedures. The first system is the Visual Tag-based navigation System (VTS), and the second is the External Optical tracker-based navigation System (EOS). This study aims to identify a more practical architecture for clinical use. Experiments conducted on a femur phantom assessed five registration algorithms, including ICP, CPD, BCPD, RANSAC, and PointNetLK. The VTS achieved an average target registration error of 9.37±4.68 mm and target visualization error of 9.31±3.20 mm, while the EOS attained a target registration error of 4.02±1.18 mm and a target visualization error of 8.40±0.81 mm. Although the EOS demonstrated a statistically significant advantage in target registration error (p0.05).
