Bridging the gap between 3D survey and use of digital data in the CH field

Recent hardware and software developments have made 3D more extensively used in specialized applications. The public's perception is evolving, and there is a growing desire for 3D: the potential of using complete and immersive data is clear to everyone. The goal is to expand access to this data simply and helpfully so that 3D can be used by everyone, not just professionals. This demand is acute in cultural heritage, but currently, 3D digital models are barely used in real working processes. Many researchers in HBIM are an example of how 3D is wished in the CH field: the concept of BIM as a building-related information system is vital, even if it is infrequently employed by conservation and restoration practitioners. The “lesson learnt” after years of research is to forgo modelling and instead use point clouds directly on internet platforms. These technologies enable the dissemination and full use of 3D survey technology in the real world, bridging the gap between digital surveys and day-to- day applications. Standard functions include measuring, cropping, annotating, and downloading. Commercial options also include VR interactivity, BIM integration, automatic registration, segmentation, and categorization of point clouds (machine learning based). Future development will transform the 3D point cloud into a 3D web information system. This is the key development that will revolutionize how technicians and other professionals communicate, share, and use digital data by allowing them to access it instantaneously and anywhere. This reduces time, preserves the model's metric relevance, and simplifies system adaption to new conditions. The debate examines the merits and prospects of more advanced web systems for direct sharing and management of image or range-based point clouds. The early research reveals potential future improvements to this unique approach of using digital survey data.
