3D-ARCH is a series of international workshops organized under the umbrella of ISPRS and CIPA. 

3D-ARCH started in 2005 in Venice and move throughout the years to Zurich (2007), Trento (2009, 2011, 2013), Avila (2015), Napflio (2017), Bergamo (2019) and Mantua (2022).

The main focus of the workshop is to discuss investigations, steps and processes for smart 3D reconstruction, modelling, accessing and understanding of digital environments from multiple data sources. Topics include:

• Low-cost sensors and open-source algorithms for terrestrial 3D modelling

• Fusion of multi-source and multi-sensors data

• Research in 3D/4D survey and modelling

• Automation in data processing

• Image matching, Multi-View Stereo (MVS) and 3D reconstruction

• Point cloud processing, semantic enrichment and analysis

• NeRF and Gaussian splatting 3D reconstruction and modelling

• Semantic and AI methods in terrestrial 3D reconstruction problems

• Accuracy requirement and assessment

• Virtual and Augmented Reality for complex architectures and heritage

• Investigations in BIM for Cultural Heritage (HBIM)

• Data sharing platform for architectural 3D models
