Intuitive, rapid and efficient in-situ measurement of complex transparent 3D objects with a focus on cultural heritage artifacts

The issue being addressed is the need to be able to rapidly digitize the mass amounts of sensitive glass cultural heritage objects available in Europe and prevent them from being destroyed and eternally lost via material decay, acts of terrorism and natural disasters. This is useful for society because cultural heritage objects are a fundamental part of the cultural identity of each country and if they are lost without the ability of being recreated, a part of a nation’s identity is lost with them. To date, glass and transparent objects are the most overlooked and tricky to digitize as no one has been able to demonstrate a system with the capability of doing so practically, in order to enable mass digitization of such objects and use of the technology by non-experts. The objective of Transparent 3D is to create an easy-to-use, non-contact measurement hardware and software package which dramatically reduces the cost of measuring complex transparent objects by greatly accelerating and streamlining the measurement procedure. The technique used will be based on the principle of non-contact optical measurement. The hardware and software package will employ a combination of techniques in order to optimize and simplify the complete 3D reconstruction process of complex transparent cultural heritage objects. The impact of the platform created and its competitive advantages over existing techniques will be demonstrated in the field with case studies conducted at three cultural heritage institutions in Greece, Italy and France. The conclusions of the action was to successfully develop and prototype a method for 3D scanning tranparent objects using an single RGB camera. It was used to rapidly digitize hollow glass cultural heritage items, and was also shown to apply to contemporary transparent glass and plastic items. On the specific objects tested, we demonstrated an accuracy of 1mm - 2mm on average, which is considered to be adequate for cultural heritage digitization and preservation applications. A patent is being applied for after which we will continue to develop the technique to improve the accuracy and also develop and commercialize the techique even further after the end of the action in collaboration with the host institution.
