Paper Abstract

The application of shape-from-silhouette methods for 3D imaging of underwater objects is explored in this paper. While there is a significant body of literature on the shape-from-silhouette technique, the reconstruction of an underwater object form a sequence of 2D lidar images present additional difficulties in both the creation and processing of silhouettes from the data, as the water optics and scattering can severely distort the silhouettes. In a recent data collection experiment, a lidar system was used to take images to create silhouettes sufficiently clear to support image reconstruction. Several 3D images were formed by applying the shape-from-silhouette technique to the 2D lidar silhouettes. With the in-air data serving as a benchmark, the 3D images of the underwater object suggest the potential for this approach.
