A novel adaptive two-stage approach to dynamic optimal path planning of UAV in 3-D unknown environments is proposed in this paper. The laser radar is exploited to incrementally build environmental maps so as to prevent the UAV from the threat of sudden obstacles. Meanwhile, by adding a vector...
Real-time path planning of UAV based on velocity vector An on-line real-time path planning is proposed for unmanned aerial vehicle(UAV) in two-dimensional dynamic environment. A real-time planning method based o... C Li,X Yi,M Hu - 《Journal of Nanjing University of Aeronautics & Astronau...
However, there might be dynamic obstacle areas in real-world situations as well. The straightforward application of the aforementioned algorithms cannot be used to solve path planning issues under dynamic threats. To resolve the problems mentioned above, this study investigates obstacle avoidance path ...
Path planning and mapping go hand in hand. Spatial representation is essential for planning, and the map is used to identify and locate objects within space. One of the objects can be the vehicle itself, as it is also part of the spatial representation. As such, localization problems are al...
With the rapid advancement of drone technology and the growing applications in the field of drone engineering, the demand for precise and efficient path planning in complex and dynamic environments has become increasingly important. Traditional algorithm
The UAV flies from the initial to final position along the flight path, providing edge computing services for the UEs along the way. Therefore, the initial and final positions of UAV satisfy the following constraints:(3)qm(0)=qm,0;qm(T)=qm,f Where qm,0 and qm,f are the initial and...
This paper analyzes the inapplicability of the traditional APF in the dynamic environment and the existence of local minimum. In this paper, a new potential field function is proposed. Combined with the fuzzy algorithm, the ratio of the absolute value of the difference between the gravitational fo...

path planning algorithms means that several flights must be made to capture multiple targets in a complex environment12. This issue is critical in the case of disaster response, in which biases and a lack of information in surveys are of particular concern. Moreover, planning multiple flight ...
