3D modeling by means of videogrammetry and laser scanners for reverse engineering

Herráez Boquera, José; Martínez Llario, José Carlos; Coll-Aliaga, Eloína; Martín Sánchez, María Teresa; Rodríguez Pereña, Jaime (Elsevier, 2016-06)

[EN] The knowledge of the 3D geometry for reverse engineering studies is based on images and/or distances. The use of scanner laser has replaced the photogrammetry in the last decade, due to its easy handling and intensive ...
Cultural Heritage Restoration of a Hemispherical Vault by 3D Modelling and Projection of Video Images with Unknown Parameters and from Unknown Locations

Herráez Boquera, José; Denia Rios, José Luís; Priego De Los Santos, Enrique; Navarro Esteve, Pablo José; Martín Sánchez, María Teresa; Rodríguez Pereña, Jaime (MDPI AG, 2021-06-08)

[EN] Reverse engineering applied to architectural restoration for the reconstruction of structural surfaces depends on metric precision. Sometimes there are elements on these surfaces whose value is even higher than the ...
Determining image distortion and PBS (point of best symmetry) in digital images using straight line matrices

Herráez Boquera, José; Denia Ríos, José Luis; Navarro Esteve, Pablo José; Rodríguez Pereña, Jaime; Martín Sánchez, María Teresa (Elsevier, 2016)

[EN] It is impossible to take accurate measurements in photogrammetry without first removing the distortion in images. This paper presents a methodology for correcting radial and tangential distortion and for determining ...
Epipolar image rectification through geometric algorithms with unknown parameters

Herráez Boquera, José; Denia Ríos, José Luis; Navarro Esteve, Pablo José; Rodríguez Pereña, Jaime; Martín Sánchez, María Teresa (Society of Photo-optical Instrumentation Engineers (SPIE), 2013-12-02)

Image processing in photogrammetry is commonly used for scene reconstruction. Although two-dimensional applications can be solved using isolated images, reconstruction of three-dimensional scenes usually requires the use ...
Modeling the thickness of vaults in the church of Santa María de Magdalena (Valencia, Spain) with laser scanning techniques

Herráez Boquera, José; Navarro Esteve, Pablo José; Denia Ríos, José Luis; Martín Sánchez, María Teresa; Rodríguez Pereña, Jaime (Elsevier Masson, 2013-12-23)

Restoring cultural heritage is an extremely important job due to its immeasurable value. However, it also requires even greater attention in the case of a building. The actions taken on these constructions not only guarantee ...
Optimal modelling of buildings through simultaneous automatic simplifications of point clouds obtained with a laser scanner

Herráez Boquera, José; Denia Ríos, José Luis; Navarro Esteve, Pablo José; Yudici Oliver, Santiago Arturo; Martín Sánchez, María Teresa; Rodríguez Pereña, Jaime (Elsevier, 2016)

[EN] In recent years, the laser scanner has become the most used tool for modelling buildings in pure documentation and structural studies. Laser scanning provides large numbers of points in a minimum amount of time with ...
Restoration of paintings on domes with non-developable geometry (Los Santos Juanes Church in Valencia)

Navarro Esteve, Pablo José; Yudici Oliver, Santiago Arturo; Herráez Boquera, José; Denia Rios, José Luís; Martín Sánchez, María Teresa; Rodríguez Pereña, Jaime (Taylor & Francis, 2018)

[EN] The restoration of paintings on elements in cultural heritage buildings (fundamentally, churches) involves two structural problems: capturing the geometry of the construction element and its development. In many cases, ...
