Research on Stereo 3D Display for Augmented Reality Surgical Navigation

Limitations exist in the application of surgical robots in clinical practice such as doctors' limited field of vision, lack of depth information, and the need to constantly switch the field of vision in the process of surgery, which affects the efficiency of surgery. In this paper, research on stereo 3D display for augmented reality (AR) surgical navigation is carried out to address the issues, which combines the technology of AR to overlay the virtual 3D model with the actual image of the operation area, providing doctors and surgical assistants with a more intuitive display method of the lesion location of patients during the operation. The stereo 3D display is presented in detail, including the theoretical research, the algorithm model, the AR effect test, and the positioning error analysis. The simulation and experiments are conducted to evaluate the performance of the stereo 3D display, which verified the practicability and effectiveness of the system and showed that the system can correctly realize pose estimation, virtual model projection, and presentation of AR effect.
