| Outline of Final Research Achievements |
We developed a pattern-light projector with ultra small size, with high brightness and long depth of focus, that can be passed through the instrument channel of normal endoscopes. Furthermore, we have developed 3D reconstruction algorithms based on active stereo methods, which is robust against subsurface scattering effects or over-exposure effects, which are typically occurs on bio-tissues lit by patterns with bright spots. By combining these results with ordinary endoscopes, we succeeded in measuring the shape of the surfaces inside stomach of a pig with the real scale.
