Abstract

We present the first prototype of 3D laparoscope using polarized lenses. Polarization encapsulates light intensity and surface orientation, from which 3D can be retrieved. Our method first acquires 3 images of the same view at 3 different orientations of the polarizer (00, 450 and 900). Second it uses Shape-from-Polarization (SfP) to calculate the surface normals. Finally it integrates the normals to estimate the 3D surface. Qualitative and quantitative comparison to Shape-from-Shading (SfS) show the effectiveness of our method and its promising use in laparoscopic surgery.
