Abstract:
A point cloud of 10 million locations was collected using sonar from a
cave approximately 90 m underwater in Florida. The extreme conditions
of the environment required the use of highly specialized and
technical diving and data gathering equipment. Registration of multiple
data sets was an initial challenge facilitated by cave radio and GPS.
Current research focuses on meshing the point cloud into solid,
polygonalized walls. In the future, the meshed walls can be texture
mapped and displayed in the RAVE 3D immersive environment to give
a viewer a virtual cave experience.
