“…Light unmanned aircraft have also seen use in the area of land surveying, particularly archeological sites, and performing photogrammetry [6]. Unmanned aircraft have also been used to perform inspections of building facades that are often difficult to reach especially with ground-based monitoring devices [7]. The applicability of autonomous unmanned aircraft for bridge inspections has also been investigated [8].…”

“…They have also found signifant use by the military [19,20]. In "Low-Cost Aerial Unit for Outdoor Inspection of Building Facades" the authors used a UAS equipped with a Microsoft Kinect sensor in order to collect geometric data from buildings [7]. A building's geometry directly influences energy performance and must be measured when inspecting building energy.…”

Applications for small unmanned aerial vehicles have exploded over the past decade. Small size, maneuverability, low cost, and versatility enable utilization for applications not readily accessible by traditional manned aircraft, such as bridge inspections.However, the challenges associated with conducting inspections in a safe, cost efficient manner currently exceed the benefits of using an unmanned aircraft for inspection.

“…Reconstruction of geometry may be carried out either by applying Structure from Motion (SfM) methods on still images or with sophisticated sensors like laser range finders or integrated solutions like the Microsoft Kinect. These data are used for deterioration analysis [9], preservation [1], or energy efficiency measuring [13]. Inspections in open, uncrowded spaces yield good results with low effort due to mostly planar path-planning and a lack of obstacles [8,14].…”

-Unmanned Aerial Vehicles (UAV) are an established utility for remote sensing and mapping purposes. Practical applications emerge in the form of inspecting structures that are hard to reach, deterioration analysis, construction monitoring or quantifying material in landfills. From a technological perspective most of these applications rely on the same established method, manual piloting by experts. While ongoing research is focused on developing reliable means of obstacle avoidance, sophisticated mission planning solutions can greatly increase the practicality of UAVs for inspection purposes. We propose an inspection planning concept for highly automated inspections in BIM projects. The application, developed in the course of this research, interacts with the firmware and the simulation capabilities of the Dronekit framework, which makes for a highly integrated and sustainable UAV. The main contribution is the 3D simulation of planned flight missions with Software-In-The-Loop (SITL) technology. The inclusion of actual flight dynamics allows the operator to perceive an authentic representation of the UAV's behaviour before take-off. Furthermore, the webbased planning application renders preview images in the virtual scene which provide a realistic impression of the results to be expected. The application automatically generates the different waypoints for obtaining photographs of a Point of Interest (PoI).

“…It complements terrestrial acquisition of 3D information . In its role as an aid to photogrammetric work, the UAV has seen many applications in various fields, such as disaster management (Achille et al, 2015;Baiocchi et al, 2013), 3D building reconstruction (Roca et al, 2013), surveying/mapping (Cramer, 2013), and heritage documentation (Chiabrando et al, 2015;Murtiyoso and Grussenmeyer, 2017).…”

ABSTRACT:Photogrammetry has recently seen a rapid increase in many applications, thanks to developments in computing power and algorithms. Furthermore with the democratisation of UAVs (Unmanned Aerial Vehicles), close range photogrammetry has seen more and more use due to the easier capability to acquire aerial close range images. In terms of photogrammetric processing, many commercial software solutions exist in the market that offer results from user-friendly environments. However, in most commercial solutions, a black-box approach to photogrammetric calculations is often used. This is understandable in light of the proprietary nature of the algorithms, but it may pose a problem if the results need to be validated in an independent manner. In this paper, the Damped Bundle Adjustment Toolbox (DBAT) developed for Matlab was used to reprocess some photogrammetric projects that were processed using the commercial software Agisoft Photoscan. Several scenarios were experimented on in order to see the performance of DBAT in reprocessing terrestrial and UAV close range photogrammetric projects in several configurations of self-calibration setting. Results show that DBAT managed to reprocess PS projects and generate metrics which can be useful for project verification.
