3D survey for the archaeological study and virtual reconstruction of the “Sanctuary of Isis” in the ancient Lilybaeum (Italy)

Fazio, Leonarda; Lo Brutto, Mauro (Universitat Politècnica de València, 2020-01-28)

[EN] In recent years, the use of three-dimensional (3D) models in cultural and archaeological heritage for documentation and dissemination purposes has increased. New geomatics technologies have significantly reduced the ...
A robust and hierarchical approach for the automatic co-registration of intensity and visible images

González Aguilera, Diego; Rodríguez Gonzálvez, Pablo; Hernández López, David; Lerma García, José Luis (Elsevier, 2012-09)

This paper presents a new robust approach to integrate intensity and visible images which have been acquired with a terrestrial laser scanner and a calibrated digital camera, respectively. In particular, an automatic and ...
Digitalización de cuevas con arte paleolítico parietal de Bizkaia. Análisis científico y divulgación mediante nuevas técnicas de visualización

Iturbe, Andoni; Cachero, Rocio; Cañal, David; Martos, Antonio (Universitat Politècnica de València, 2018-01-10)

[EN] We present three case studies illustrating the virtual reproduction of caves that belong to the most important artistic ensemble of the Paleolithic from Bizkaia (Spain): Benta Laperra, Askondo and ...
Efficient lens distortion correction for decoupling in calibration of wide angle lens cameras

Ricolfe Viala, Carlos; Sánchez Salmerón, Antonio José; Valera Fernández, Ángel (Institute of Electrical and Electronics Engineers (IEEE), 2013-02)

In photogrammetry applications, camera parameters must be as accurate as possible to avoid deviations in measurements from images. Errors increase if wide angle lens cameras are used. Moreover, the coupling between intrinsic ...
Estimation of the Precision of a Structured Light System in Oil Paintings on Canvas

Sánchez-Jiménez, David; Buchón Moragues, Fernando Francisco; Bravo, Jose Maria; Sánchez Pérez, Juan Vicente (MDPI AG, 2019-11-14)

[EN] The conservation and authentication of pictorial artworks is considered an important part of the preservation of cultural heritage. The use of non-destructive testing allows the obtention of accurate information about ...
Multiclass semantic segmentation for digitisation of movable heritage using deep learning techniques

Patrucco, Giacomo; Setragno, Francesco (Universitat Politècnica de València, 2021-07-14)

[EN] Digitisation processes of movable heritage are becoming increasingly popular to document the artworks stored in our museums. An increasing number of strategies for the three-dimensional (3D) acquisition and modelling ...
Smartphone-based video for 3D modelling: Application to infants cranial deformation analysis

Lerma, José Luis; Barbero-García, Inés; Marqués-Mateu, Ángel; Miranda, Pablo (Elsevier, 2018)

[EN] The use of smartphones cameras for photogrammetric purposes is increasing. However, the suitability of smartphones for 3D modelling for medical purposes in general, and for cranial deformation in particular, is still ...
