“…However, they allow easy georeferencing of the model and the results suggest that control points is the optimal level for modelling. The same conclusion has emerged from the analysis of horizontal reconstructions [34]; therefore, this parameter is less relevant for both vertical and horizontal structures, according to the test definitions. Although the optimal values obtained for each parameter can be used to construct a model with minimal error, it is not always the most convenient combination of parameters.…”

“…Depending on the objectives of the virtual model, this typically translates to a value of 70/90, particularly when the separation distance between the UAV and the façade is considered to be 10 or 15 m. Although the optimum value of the distance parameter is 5 m, it is also possible to use a value of 10 m to obtain a model that offers a high level of detail and allows the image acquisition process to be carried out in less time. Although the conclusion seems logical because more information is captured in this way, the same recommendation has also been obtained empirically in the research of Plaza et al [34].…”

“…This point is consistent with the findings of Sanz et al [42], who suggested that accuracy can be increased by integrating a larger number of control points in the virtual construction of a model. Compared with the base method for horizontal reconstructions by Plaza et al [34], the trend agrees, i.e., the discrepancies between the field coordinates and those recorded from the reconstructed models are in the order of centimetres.…”

“…Based on the recommendations provided by Plaza et al [34], who proposed a methodology for obtaining the parameters of a UAV to measure potholes in road structures, we propose an adapted methodology that focuses on vertical structures (See Figure 2). Although the proposed methodology maintains the basis of the original scheme, specific aspects have been modified.…”

“…Although the associated parameters can have an influence, they are also associated with the uncertainties inherent to the flight (practical handling by the user) and the characteristics of the algorithms of the photogrammetric reconstruction software. Although they seem very relevant, the studies (including this one) have discarded these other aspects since their influence is minor, especially considering the practical purposes of the research and the possibilities of users to influence more optimal flights and reconstructions [7,25,34].…”

Heritage façades are relevant to the historical preservation and identity of a city. Their deterioration can cause the devaluation of the urban environment, together with accidents caused by possible detachment of their different elements; therefore, maintaining them is crucial. It is important to have early warning systems in place, systems which would indicate potential damage and deterioration of such façades, which can be caused by factors such as humidity, earthquakes, the passage of time, or even people. This is often done through visual inspection; however, visual inspection is often affected by external factors, such as the financing of the on-site inspection and the availability of experts. Unmanned aircraft vehicles (UAVs) are a practical and economical tool that has facilitated and improved imaging by regulating parameters such as camera angle, capture distance and image overlap, thus allowing improvements in photogrammetry techniques for virtual reconstruction processes. Although the implementation of this technology has been studied in recent years, research has focused primarily on horizontal structures, such as roads. In the case of vertical structures, flight parameters are traditionally defined by trial and error, without any methodological procedure. Therefore, this paper proposes a methodology to calibrate UAV flight parameters to build a photogrammetric 3D model of a vertical structure. This proposal is based on the development of a series of experiments configured through Taguchi orthogonal arrays, which is a method that significantly reduces the number of experiments required. This methodology is applied to a case study of a façade with architectural heritage features. The results obtained offer a flight plan and the optimal parameters to achieve efficiency in the capture of images in an inspection of heritage façades, thus achieving the optimisation of resources and time.

The unstructured construction site with a complex and changeable environment brings challenges to human–machine interaction. In this study, the earthwork digital twin (DT) is proposed to realize accurate and real‐time perception, which can support the teleoperation of an automated bulldozer. The overall framework includes anterior‐time DT, real‐time DT, and posterior‐time DT, which integrates three‐dimensional modeling, edge detection, and blade trajectory algorithms. Multidimensional heterogeneous data in bulldozer teleoperation can be displayed in real‐time to ensure construction safety. Big data during teleoperation of the construction process can be collected, stored, and analyzed. The DT proposed in this study was successfully applied in a major construction project in China, and testing results show its universality, robustness, and advanced performance. The key technologies proposed in this study can be applied to solve the common problems in the construction industry, which is promising for future intelligent construction.
