Geomagic 3D Imaging Software Utilized by English Heritage

By DE Editors

Geomagic has announced that its 3D imaging and reverse engineering software, Geomagic Studio, has been used to create what it says is the highest resolution, most dimensionally accurate 3D digital model ever of the world-famous, 5000 years old monument, Stonehenge, in England.

The project has been undertaken by surveying and 3D laser scanning specialists Greenhatch Group Ltd. on behalf of English Heritage, who are the custodians and conservators of Stonehenge as well as many other historical monuments, buildings and ancient sites across England.

Together with Atkins Mapping and Archaeo-Environment Ltd., Greenhatch used short- and long-range laser scanners from Z+F UK and Leica Geosystems, along with other survey equipment, to digitally capture all the visible faces of the standing and fallen stones, as well as the tops and faces of the lintels, to a resolution of +/- 0.5mm. Surveys of all the stone faces to this level of accuracy have never been achieved before. The surrounding landscape was also captured as part of the overall project to create the most accurate 3D digital model ever of the monument.

The data captured by the scanners was read into Geomagic Studio software where it was processed to create highly accurate 3D digital polygon mesh models of the individual stones and the surrounding landscape. The individual stones could then be placed digitally in their correct positions to create a highly accurate 3D virtual model of the whole monument, which in turn could be placed accurately within the virtual model of its real-world context.

The digital models are being used for a number of purposes. They provide a precise base-line to enable English Heritage to monitor the physical condition of the monument, which is subjected to daily weathering. They are also a valuable resource to anyone wishing to produce reconstruction models, drawings or images for public understanding and interpretation and to create animation sequences. This will allow experts from English Heritage to fly virtually through and over the monument from different perspectives in order to aid their studies of the stones “and for their work on the proposed new visitor center at Stonehenge.
