Special Issue Information

Dear Colleagues,

Unmanned Aerial Vehicle (UAVs) constitute highly effective tools for remote sensing applications in a wide range of disciplines, including Earth science, structural inspections, agriculture, archaeology and many more. The rapid development over the past two decades of flight vehicles; guidance, navigation and control algorithms; and science-specific sensors has increased their capabilities to become useful to not only specialized technicians but to the general scientific and technical community.

This Special Issue seeks original contributions addressing the advances, challenges and applications of UAVs in civilian remote sensing missions. Topics can include specific science applications and techniques, as well as fieldwork case studies; flight vehicle design topics such as aerodynamics, flight dynamics and control; sensor technology related to UAV applications; AI applications; safety and airspace considerations; routing and autonomy; regulatory issues; as well as education efforts.

Remote sensing includes all civilian use fields where aerial observations are made, ranging from Earth science to structural and infrastructural inspections and even extending to planetary exploration. All categories of UAVs will be considered, including rotary wing, fixed wing, lighter than air and combinations thereof.

Addressing the problem that traditional methods cannot reliably monitor surface subsidence in coal mining, a novel method has been developed for monitoring subsidence in mining areas using time series unmanned aerial vehicle (UAV) photogrammetry in combination with LiDAR. A dynamic subsidence basin based on the differential digital elevation model (DEM) was constructed and accuracy of the proposed method was verified, with the uncertainty of the DEM of difference (DoD) being quantified via co-registration of a dense matching point cloud of the time series UAV data. The root mean square error calculated for the monitoring points on the subsidence DEM was typically between 0.2 m and 0.3 m with a minimum of 0.17 m. The relative error between the maximum subsidence value of the extracted profile line on the main section after fitting and the measured maximum subsidence value was not more than 20%, and the minimum value was 0.7%. The accuracy of the UAV based method was at the decimeter level, and high accuracy in monitoring the maximum subsidence value was attained, confirming that an innovative strategy for monitoring mining subsidence was realized.

Aerial cameras are one of the main devices for obtaining ground images in the air. Since the industrial community sets higher requirements of aerial cameras’ self-locating performance yearly using aerial cameras to locate ground targets has become a research hotspot in recent years. Based on the situation that no ground control point exists in target areas, the calculation principle of the aerial remote sensing image positioning algorithm has been analyzed by establishing different positioning models. Several error analysis models of the positioning algorithm based on the total differential method and the Monte Carlo method are established, and relevant factors that cause the positioning error are summarized. The last section proposes the optimization direction of aerial camera positioning algorithms in the future, which are verified by related simulation experiments. This paper provides a certain degree of guidelines in this area for researchers, who can quickly understand the current development and optimization direction of target geo-location algorithms of aerial remote sensing imagery.
