PRoVisG Cave 3D Reconstruction

Synopsis: Camera data from the PRoVisG system will be used to generate a 3D reconstruction of (parts of) the cave, with a rendered fly-through video as ultimate result.

Description

The FP7-SPACE Project PRoVisG aims at optimum exploitation of vision data taken from the surface of planetary bodies. To verify the capability of 3D vision processing tools developed in PRoVisG it is of utmost importance to use images taken in representative environment for testing, in particular environment that represents extreme conditions on other planets and moons. The cave is a complex surrounding in many aspects, such as morphology and illumination dynamics.

For PRoVisG Cave 3D Reconstruction it is intended to capture a major part of the cave from different viewpoints by a high-resolution SLR camera. One single tripod will be used to enable different exposure times of the same image to cope with the large illumination differences to be encountered. Complementary exposures may be taken making use of a flash.

The data will be used to generate a 3D reconstruction of (parts of) the cave, with a rendered fly- through video as ultimate result. It is intended to do some processing still during the ongoing tests to verify the usability & completeness of the captured images, however without any commitment at this stage, that result data will be available during the experiment.
