Abstract. In civil, architectural and environmental fields photogrammetry is one of the most common solutions for deriving geometric information about many kind objects interest. Photogrammetric surveys suffer need ground control points (GCPs), well distributed over survey area, to scale georeference produced 3D data. The placement GCPs both time-consuming sometimes infeasible because constrain...

Recently, multirotor UAVs have been widely used in high-precision terrain mapping, cadastral surveys and other fields due to their low cost, flexibility, high efficiency. Indirect georeferencing of ground control points (GCPs) is often required obtain highly accurate topographic products such as orthoimages digital surface models. However, practical projects, GCPs are susceptible anomalies caus...

Abstract. The world-wide absolute geographic positioning accuracy of optical Satellite imagery is mostly about a few pixels the image resolution. So for example WorldView-3 images have CE90 4 m. Also direct georeferencing without ground control information aerial in same range one to metres. These inaccuracies originate predominantly uncertainties angular measurements sensor attitude. An error ...

Convex optimization also determines the next estimate based on the observation at previous points. In this sense, optimization has a close connection with active learning. An interesting question is: what if we become “passive” in optimization? That is, how important is adaptivity in optimization? Understanding this kind of problems becomes crucial in settings where observing a single point tak...

In connection with the development plan of USK campus II area, it is necessary to map area support and complete data. Mapping an Unmanned Aerial Vehicle (UAV) a strategy or way for large-scale mapping faster more efficient time. It can save time compared using conventional survey methods. Ground Control Point (GCP) measurements are carried out geodetic GNSS improve accuracy/correction geometry ...

In this article, we report about the first results of the mapKITE system, a tandem terrestrial-aerial concept for geodata acquisition and processing, obtained in corridor mapping missions. The system combines an Unmanned Aerial System (UAS) and a Terrestrial Mobile Mapping System (TMMS) operated in a singular way: real-time waypoints are computed from the TMMS platform and sent to the UAS in a ...
