“…This thermography is applied to the 3D data by using a 2D/3D matching method, such as the one described that Laguela et al, (2013) described. Figure 5 shows the 3D thermal model generated by using this 2D/3D matching method.…”

“…Afterward, virtual 3D data for inside of the window is generated, and infrared thermography is fused to the window area. Laguela et al, (2013) proposed a method to generate an infrared thermography-textured asbuilt model that combines 3D data and infrared thermography without fixing the relative position of the sensors. The two-dimensional (2D) features are extracted from the infrared thermography, and the 3D features are extracted from the 3D data.…”

The integration of three-dimensional (3D) data with infrared thermography has received much attention for its potential use as input data for building energy simulations. Therefore, researchers have proposed methods to integrate 3D data with infrared thermography obtained by different sensors. These studies show the potential of the integration of 3D data and infrared thermography using various systems. However, these studies have ignored property aspects of infrared thermography, such as the low resolution of infrared thermography and external environmental influences. Thus, their proposed methods to integrate 3D data and infrared thermography are inadequate because these problems can affect the resulting building energy simulation. This research proposes a framework that integrates infrared thermography and 3D data while accounting for the resolution and shadow effect of infrared thermography. The proposed framework consists of three steps. In the resolution enhancement step, bi-cubic interpolation is proposed. In thermal data correction from the shadow effect, the shadow area is detected from the visible image, and then the shadow effect is removed from the registered infrared thermography. Finally, enhanced infrared thermography is mapped to the 3D data obtained by a laser scanner. The performance of the proposed framework was evaluated using test images obtained from a building in operation. The experimental results show that the proposed framework provides a 3D thermal model that is useful and accurate in simulating building energy. It is expected that the 3D thermal model can be used for accurate energy simulation of existing buildings. In addition, the proposed framework can be applied in defect detection for buildings. Furthermore, this novel approach enhances infrared thermography using visible images.

“…In recent studies this information has been registered with a point cloud for its combination with geo− metric information towards its location and accurate mea− surement of the affected areas [8][9]. These studies are usu− ally performed from a terrestrial point of view, either by an operator walking around the building [10], or by a terrestrial mobile platform from where data is acquired as a sequence [11].…”

Aerial thermography is performed from a low−cost aerial vehicle, copter type, for the acquisition of data of medium−size areas, such as neighbourhoods, districts or small villages. Thermographic images are registered in a mosaic subsequently used for the generation of a thermographic digital terrain model (DTM). The thermographic DTM can be used with several purposes, from classification of land uses according to their thermal response to the evaluation of the building prints as a function of their energy performance, land and water management. In the particular case of buildings, apart from their individual evaluation and roof inspection, the availability of thermographic information on a DTM allows for the spatial contextualization of the buildings themselves and the general study of the surrounding area for the detection of global effects such as heat islands.
