Keypoint-based Framework for Multi-instance Instrument Pose Estimation in AR Surgical Navigation
In surgical navigation systems, accurately identifying and localizing the spatial positions of surgical instruments is the foundation of scene perception and human-computer interaction. This paper proposes a novel keypoint-based framework for multi-instance instrument pose estimation in AR surgical navigation, addressing limitations of marker-based methods and achieving real-time, accurate results by integrating a keypoint-based network with the Perspective-n-Point method. This innovation significantly advances precision and efficiency for complex surgical procedures.
