“…Even without metadata in the images, they obtain first IR point clouds. Sabato et al 13 present further measurements and results with a FLIR Vue Pro, including IR point clouds and a reconstructed mesh using Pix4Dmapper. They state that RGB and IR images cannot be used within one SfM workflow due to the "impossibility to properly define common image descriptors".…”

“…They state that RGB and IR images cannot be used within one SfM workflow due to the "impossibility to properly define common image descriptors". 13 Javadnejad et al 14 use SfM to generate RGB point clouds. By 2D or 3D co-registration, they obtain IR point clouds which have higher accuracy, point density, and reliability than SfM solely based on IR images.…”

“…As mentioned previously, an efficient way of developing thermal models in the combination of BIM is laser scanning that provoked a heated debate over the last decade. [101][102][103][104][105][106] Image processing has great potential for creating thermal models; however, a few issues remain with the methodology. Regardless of low-quality infrared images and the negative influence of external-beam radiation, the approach's main downside is the inability to monitor the construction projects in an automated manner.…”

“…Based on the SFM algorithm, it can obtain centimeter-level precision 2D maps and 3D models from the ground, a light UAV, or aerial image processing. Since some scholars have verified the feasibility of using Pix4Dmapper for thermal infrared 3D reconstruction [22], this paper uses it for 3D reconstruction directly. As shown in Figure 6, the 743 images collected above are imported into Pix4Dmapper.…”

“…It was obvious that this method was a combination of a 2D image and a 3D model, but the temperature of the building enclosure can only be read in the 2D image. In another study in 2020, the established 3D model did not have specific temperature information either [21,22]. In 2018, Chen Yingying captured the image of the building by carrying two cameras (a TIR camera and an optical camera) in the UAV simultaneously, and then combined TIR images and optical images to reconstruct the 3D building model efficiently and accurately.…”
