CFG-NeRF: coordinate-feature-gate collaborative optimization for sparse-view ancient architecture reconstruction

This paper started with a two-dimensional image of ancient Chinese architecture. Firstly, it detected edge of target to obtain the contour and detected its corner points, which would be used to get contour curve equation. Then a rotating body reconstruction method based on the cross-sectional radius was proposed. It realizes the modeling of 3D rotation. What's more, non-photorealistic rendering of the three-dimensional model was also achieved.

Autor se věnuje otázce historických nádraží a železničních staveb jako svébytného druhu industriální architektury i možností jejich památkové ochrany v rámci činnosti NPÚ v Praze a uvádí řadu příkladů v tomto směru. Uvádí rovněž některé odborné otázky a praktické obtíže při jejím zajišťování. V další části článku se zabývá areálem nádraží v Praze Vršovicích z let 1872-1899 a zdařile provedenou rekonstrukcí jeho neorenesanční budovy realizovanou v letech 2003-2009 včetně obnovy interiéru.

The open access book combines extensive knowledge on the topic of digital 3D reconstruction of historical architecture

The remains of buildings from the Archaic period and earlier are often exiguous, yet there is understandable pressure to reconstruct the original form of those of particular significance for architectural history. Such is the case for both the Toumba building at Lefkandi (c. 950 BCE) and the Temple of Artemis at Corfu (c. 580 BCE). The standard reconstructions of both, however, are probably not viable as structural/constructional solutions. The former cannot have been as monumental as thought and may not have had a “veranda” (or proto-peristyle). Meanwhile the Corfu temple was not as wide as thought; it probably had seven rather than eight columns across the front and a narrower span for its “pseudo-dipteral” pteron. Demonstrating the problems with the previous reconstructions while proposing new ones opens up two kinds of discussion: one about the role of structural calculations in the reconstruction of ancient architecture, the other about the overemphasis placed on the peristyle in the development of the Greek temple.
