“…RGB images are processed through a photogrammetric bundle adjustment, and as the relative orientation between RGB and IR cameras is known, thermal images are oriented. Previtali et al (2013) compute an integrated bundle adjustment of RGB and IR imagery, after the preliminary independent calibration of both sensors. After that, texture is applied to a 3D mesh created from the point cloud.…”

“…In the following, the authors discuss some attempts to increase the automation of the process of integrating surveyed 3D models and IRT, either in the phase of data acquisition and data modeling. In either the former problem the integration of geometric data, visible and IR texture is not yet a fully automated process both using TLS (Costanzo et al, 2015) or digital photogrammetry (Previtali et al, 2013). Although at present the acquisition techniques allow to obtain dense point clouds in a relatively easy way, mapping thermal data very often require an additional modelling step, which may be time consuming (Previtali et al, 2014).…”

“…The registration of individual images to the 3D model using space resection (Luhmann et al, 2014) would require too much effort, on one side for the necessity of manually measuring a terrific number of control points, on the other because the identification of such points on a purely geometric model (without photorealistic texture) may be a complex task. The solution proposed in Alba et al (2011) and Previtali at al. (2013) instantiated a new approach exploiting RGB images to help co-registration between 3D model and IR images (see Sect.…”

The thermal analysis of buildings represents a key-step for reduction of energy consumption, also in the case of Cultural Heritage. Here the complexity of the constructions and the adopted materials might require special analysis and tailored solutions. Infrared Thermography (IRT) is an important non-destructive investigation technique that may aid in the thermal analysis of buildings. The paper reports the application of IRT on a listed building, belonging to the Cultural Heritage and to a residential one, as a demonstration that IRT is a suitable and convenient tool for analysing the existing buildings. The purposes of the analysis are the assessment of the damages and energy efficiency of the building envelope. Since in many cases the complex geometry of historic constructions may involve the thermal analysis, the integration of IRT and accurate 3D models were developed during the latest years. Here authors propose a solution based on the up-to-date photogrammetric solutions for purely image-based 3D modelling, including automatic image orientation/sensor calibration using Structure-from-Motion and dense matching. Thus, an almost fully automatic pipeline for the generation of accurate 3D models showing the temperatures on a building skin in a realistic manner is described, where the only manual task is given by the measurement of a few common points for co-registration of RGB and IR photogrammetric projects.

“…Finally, the integration between thermal data and geometric building model is obtained by mapping thermal images on the 3D semantically enriched model of the building. Main steps of processing IRT data are reported in the following subsections, while more details can be found in Previtali et al (2013).…”

Automatic façade modelling using point cloud data for energy-efficient retrofitting

et al. 2014

Energy-efficient retrofitting of existing buildings is a key aspect for reaching the proposed energy consumption reduction targets fixed by public authorities in different countries. For this task, the availability of as-built building models is of primary importance for both diagnosis of thermal dispersion and designing of retrofitting. In this paper, we present an automated methodology to derive highly detailed 3D vector models of existing building façades starting from terrestrial laser scanning data. The presented methodology first accomplishes the segmentation of the point cloud of a building façade into its planar elements. Then, starting from the identified planar clusters, façade breaklines are automatically extracted to be used later to generate a 3D vector model. During this final step, some priors on urban scenes like the prevalence of straight lines and orthogonal intersections are exploited to set additional constraints. The final product is a semantically enriched 3D model of the building façade that can be integrated in Building Information Model (BIM) for planned maintenance. Eventually, the integration between derived façade models and infrared thermography (IRT) is presented for energy efficiency evaluation of buildings and detection of thermal anomalies.

The generation of 3D models of buildings has been proved as a useful procedure for multiple applications related to energy, from energy rehabilitation management to design of heating systems, analysis of solar contribution to both heating and lighting of buildings. In a greater scale, 3D models of buildings can be used for the evaluation of heat islands, and the global thermal inertia of neighborhoods, which are essential knowledge for urban planning. This paper presents a complete methodology for the generation of 3D models of buildings at big-scale: neighborhoods, villages; including thermographic information as provider of information of the thermal behavior of the building elements and ensemble. The methodology involves sensor integration in a mobile unit for data acquisition, and data processing for the generation of the final thermographic 3D models of urban environment.
