AI Technical Summary
Existing augmented reality systems face challenges in accurately registering computer-generated graphics with the real-world environment, especially when the registered graphics do not represent visible objects, leading to misalignment or 'drift' in applications like surgical navigation.
A method and system that utilize a multi-modal marker device with both visible fiducial markers and tracking sensors, combined with cameras and a three-dimensional tracking system, to compute affine transforms for real-time registration of the tracking system with the augmented reality coordinate system, allowing continuous alignment of internal anatomical structures despite movement.
Enables precise, real-time alignment of computer-generated models with the patient's body, correcting for misalignment issues and ensuring accurate superimposition of internal anatomical structures in augmented reality displays.
