Outline of Final Research Achievements

We developed methods for measuring 3D shape by using scattering in participating media. Two different approaches were developed; 3D reconstruction with a spot laser and with multiple spot lights. Our method with a spot laser can measure occluded surfaces by using scattering of laser and reflected light. Our method with multiple spot lights improves the accuracy of measurement. We also constructed a measurement system with water tank, laser and cameras, and evaluated the effectiveness of our methods.
