The order of magnitude would be an initial investment that is 30 times less in both software and equipment if we compare it with current equipment, such as BLK 360 from the Leica company.

Comparatively, this technology is cheaper than traditional scans carried out with TLS (terrestrial laser scanner). In our specific case, the DJII Mini 2 UAV equipment and the Agisoft Metashape software were used. Generate digital twins” is proposed using photogrammetry, because it is an affordable system in terms of both equipment and technology. Figure 4 shows the main stages of this work. The ultimate goal is the aforementioned universal accessibility.Īs we indicate above, a premise of this work is that the workflow is low cost. These metaverses were critically assessed and screened, looking for the most suitable one to be integrated into an effective workflow that satisfies a series of imposed premises, such as being suitable for use in virtual reality and augmented reality environments. Different databases and metaverses were studied, understanding them as new systems for the representation and dissemination of architecture. To obtain this workflow, we worked with digital twins obtained by photogrammetry. This universal accessibility is based on new metaverses to offer experiences that allow us to overcome physical barriers and reach any user regardless of their economic or physical condition or their location. These twins will guarantee the preservation and dissemination of cultural assets and will promote universal accessibility through new technologies, such as databases, metaverses, virtual reality, augmented reality or gamification.

The objective of this article is to generate and validate a workflow that allows us to use virtual twins obtained from unique buildings of our architectural heritage.
