The scanner is the outcome of the 3Dunderworld project. It is an innovative hardware and software solution for the rapid scanning and 3D reconstruction of objects, which can help to the mapping of underwater cultural sites.
Questions this practice may help answer
How can underwater sites be mapped?
Iplementation Context
Recently, there has been an increase in the demand of virtual 3D objects representing real-life objects. A plethora of methods and systems have already been proposed for the acquisition of the geometry of real-life objects ranging from those which employ active sensor technology, passive sensor technology or a combination of various techniques. The present software / hardware has been developed within the frame of the 3DUNDERWORLD project.
Aspects / Objectives
The 3Dunderworld project successfully developed three prototype systems that improve underwater 3D scanning. Thus, the undertaking also helped develop marine archaeology.
The first prototype system combined active and passive sensors, and involved a projector and camera. While the results were high fidelity, the system required objects to remain motionless throughout the entire 20 to 30-second imaging process. Another prototype utilised recent high-speed acquisition technologies, replacing the standard digital camera with a special high-speed version. The system, hence, required a far shorter period of motionlessness, less than 1 second, thereby being more realistic for marine use. Prototype three utilised a low-power laser, replacing the projector, plus a pair of cameras. The system is advantageous for deep-water use. Single- and triple-beam versions were also developed.
Main Outputs / Results
The systems address the complexities and problems associated with the data acquisition, processing and reconstruction of objects situated underwater. The development of such a system will enhance the techniques available to underwater archaeologists and exploration groups in general, since it will significantly accelerate the documentation and mapping process.
Transferability
This technology could be used for rapid scanning and automatic 3D reconstruction of underwater sites. It can help to the mapping of underwater sites and lead to the better protection of underwater cultural heritage. For maritime spatial planners, this technology would help the registration and evaluation of archaeological sites, as well as and the support to selecting potential protection zones.
