A Status Quaestionis and Future Solutions for Using Multi-light Reflectance Imaging Approaches for Preserving Cultural Heritage Artifacts

Single-Camera Multi-Light scanning methods like Reflectance Transformation Imaging (RTI) and Portable Light Dome (PLD) are being widely used in the cultural heritage sector. Both technologies followed a long development track in collaboration with cultural heritage partners, resulting in matured technologies. In this short paper, we highlight recent progress with this technique (capturing and modeling reflectance, multi-spectral pipelines, material classification) and present ongoing work of how both technologies can be brought closer together. Finally, we address RTI’s and PLD’s challenges and possible solutions in terms of long term preservation and valorization by the scientific community.
