Automatic 3D Modelling of Excavation Sites

In this collaboration with the archaeology department of Kiel university, a scene reconstruction has been performed based upon two photographs only:

Image Image

The images are automatically matched


and robustly calibrated providing a sparse set of verified correspondences


Finally a depth map can be produced containing for each pixel the distance of the imaged object from the camera center:


This can then be "backprojected" to yield a 3D surface model either with the original colors


or with a pseudo-color to better visualize the geometrical shape:


Such models could automatically be created for each excavated layer to finally obtain a 4D (3D + time) model of the excavation site.
