| Outline of Final Research Achievements |
In this research project, we developed fundamental technologies for intelligent archive of the laparotomy videos. In the fusion of multiple videos for retrieving the surgical field from obstructions by surgeon’s head and hands, we first merge video streams by the perspective transformation, followed by the precise fusion by FFD (Free Form Deformation), which is one of non-rigid image registration methods. As the result of validation, the target registration error was 60.5 px (±7.9). Also, we developed a method for the fusion among tiny cameras which were set on the surgeon’s head and fixed cameras located around the subject. The fused video is displayed on the Oculus, which is a device for virtual reality with high immersion. We tested the developed methods at the real environment of the operation room and confirmed that our fusion methods worked well, though there are some rooms to improve.
