Abstract:
In this paper, we propose a stereo 3D reconstruction from a single image including multiple water drops. Water drops on a surface, e.g. camera lens, refract light rays and the refracted rays are roughly converged to a point. This indicates that water drops can be regarded as approximately small lens. Therefore, sub-images refracted by water drops can be regarded as images taken from different viewpoints. That is, virtual stereo camera systems can be constructed from a single image by using these raindrop characteristics. In this paper, we propose an efficient description of this virtual stereo camera system using water drops. Furthermore, we propose methods for the estimation of the camera parameters and for the reconstruction of the scene. We finally display several experimental results and discuss the validation of our proposed camera model from the results.
