3D reconstruction with fisheye images strategies to survey complex heritage buildings

Using fisheye lenses in photogrammetry can significantly reduce the time needed to survey complex medieval heritage buildings, such as castles, while capturing detailed geometric and radiometric information. This method addresses challenges posed by inaccessible locations, occluded structures, and varied spatial complexities, often encountered in traditional photogrammetric surveys using conventional lenses or laser scanning. The approach eliminates the need for low-altitude Unmanned Aerial Vehicles (UAVs) and streamlines data collection across interconnected areas of a building. Researchers demonstrated its effectiveness by surveying the Castle of Sesimbra and the Convent of Christ in Portugal, showcasing its potential to revolutionize digital reconstruction of intricate heritage sites.
