“…And therein lies the added value of point clouds as containers of qualitative-topological information. In laser scanners use, it is well known the use of reflectance to discover differences in the documented surface: color, composition, texture, moisture (Puche Fontanilles et al, 2017). However, before using this device, it is necessary to consider a series of issues which depend on the characteristics of the built heritage to be surveyed: they concern the lighting, the distance up to which the accuracy values of the device can be assumed, and the visibility limitations that require multiple scanning positions.…”

Abstract. This contribution illustrates the results of research that aims to connect the workflow for knowledge – survey, interpretation, modeling – to the transmission of this knowledge and enhancement of Cultural Heritage by physical models, demonstrating its potential in a “Design for All” perspective. Palazzo Mazzonis, the current seat of the MAO (Museo d’Arte Orientale), is one of the many buildings in the historic city center of Turin characterized by a particular complex vaulted atrium: it has been investigated through TLS survey tools for the production of two-dimensional drawings (for the detailed representation of architectural features) and three-dimensional models (for the interpretation of the design idea through geometry). The last phase of work aims to translate the interpretative digital models into tactile models for Cultural Heritage transmission, through processes of digital fabrication, with obvious impacts on the visit path inside the museum, also with didactic purposes.

“…Previous work was proposed to conduct a survey and compare the results with the data obtained from the massive point cloud (Serrano et al 2014). Other works have been carried out with the photogrammetry technique especially focused on restitution (Astorqui 2003) and photogrammetry dedicated to real estate (Almagro 2000); and more recently extract from the cloud of orthophoto-points of various planes, in JPG or TIFF format with color inversion, (Puche Fontanilles et al 2017). Advancing in technology, the plans were obtained by means of transfer of vector support, on which the measures were taken.…”

Currently, the plans for the protection of historical groups tend to be sustainable in the management of Heritage, covering the conservation, intervention and dissemination phases. The interoperability of operators in rehabilitation -archaeologists, architects, historians, engineers, restorers -is essential and for this it is necessary that there is a workflow. In addition, new data acquisition technologies, scanning and photogrammetry techniques, are helping to capture the real state of historical constructions, allowing an analysis of processes, materials and pathologies, essential for prevention and maintenance. of the historical building. These standardized operations provide us with data that must be continuously recorded. A para-loyal commitment is the management of the information collected by the different experts, its sharing and the deposit in an alphanumeric data container model. It is here that the H-BIM project takes a fundamental role, having a virtual 3D model of multidisciplinary information.In this investigation a workflow is developed in which the numerical models obtained through laser and photogrammetry scans and the parametric model based on the orthophoto sequences generated in a previous restoration are superimposed. For this, the Church of the Society of Jesus is taken as a study, emblem of that Latin American baroque that the Jesuit order built between 1605 -1765 in Quito (Ecuador). The preparation phases are structured to adequately model a historical building of these characteristics, breaking down the different stages and presenting its Level of Development -LOD-, detail and information.

La reconstrucción 3D a partir de técnicas fotogramétricas ha presentado un desarrollo continuo en los últimos años, siendo estudio de muchos académicos inmiscuidos en la temática, buscando nuevas formas de realizarla, siempre intentando reducir costos tanto económicos como de software; es por esta razón, que en el presente documento para espacios culturales y turísticos de Bogotá Colombia, se ejecuta la implementación de imágenes 360° obtenidas de forma gratuita de Google Street View, a fin de realizar sus reconstrucciones. Esta metodología dará como resultado la obtención de una nube de puntos densificada, así como la malla texturizada asociada, para cuatro (4) casos de estudio de sitios turísticos de Bogotá Colombia: Chorro de Quevedo, Plaza de Toros de Santamaría, Plaza de Bolívar e Iglesia la Bordadita, a su vez, realizando una comparativa entre la reconstrucción de espacios abiertos, cerrados y semicerrados.
