The Great Wall of China in 3D

Sep 19, 2014 -- The project of modeling the Great Wall of China in 3D was officially launched last September 16, 2014. It will be supervised by China's Ministry of Culture and State Administration of Cultural Heritage and funded by China Great Wall Society and UNESCO.

The goal of this project is to protect, document and promote the Great Wall of China to the world. To this end, 3 years will be dedicated to create the whole 6,000km length of the Great Wall of China and its surroundings in 3D, in high resolution.

Thanks to its Chinese reseller IFA Tech, Acute3D's Smart3DCapture solution has been chosen for the 3D automatic reconstruction part, which will be combined with ground imagery and laser scanning. Using Smart3DCapture, Redbird Helicopter Surveying Technology has already produced a part of the Great Wall of China in 3D from images taken by helicopter.

Renaud Keriven, President & CTO of Acute3D is very enthusiastic about this project: “Mapping such an incredible man-built structure, long enough to be visible from space, dating back so many centuries, is a project which embodies the ability of the human beings to use progress to better understand their History and preserve its heritage. At Acute3D, we are working very hard to deliver best-in-class solutions which support this amazing enterprise and more generally the reconstruction of many cultural heritage objects and masterpieces around the World.”

About Acute3D Company

Acute3D develops and sells Smart3DCapture, a software solution allowing to produce high resolution 3D models from simple photographs, without any human intervention.

The principle of Smart3DCapture is to analyze several photographs of a static subject, taken from different viewpoints, and to automatically detect pixels corresponding to a same physical point. From many such correspondences, relative orientations of photos and accurate 3D shape of the scene can be inferred.

Smart3DCapture solves this problem with cutting edge photogrammetry, computer vision and computational geometry algorithms fulfilling industrial-quality requirements in terms of precision, scalability, efficiency, usage, robustness and interoperability.

About Smart3DCapture

Smart3DCapture Advanced allows the production of high resolution 3D models as well as the generation of digital surface models (DSM) and true orthophotos from imagery datasets as big as 10 gigapixels. It is most suited for, but not limited to, UAS/UAV/drone operators.

Smart3DCapture Expert pushes the limits of the Advanced edition with an extension to 30 gigapixels per input imagery dataset, and a batch processing ability through a job queue. It is the perfect solution for demanding scanning and surveying projects.

Smart3Capture Ultimate is dedicated to larger-scale 3D surveying and mapping. It can handle an unlimited number of photographs without any limitation in size, and allows computations to be parallelized on a cluster of 3D reconstruction engines.
