  In response to the gap in considering wind conditions in the bridge
inspection using unmanned aerial vehicle (UAV) , this paper proposes a path
planning method for UAVs that takes into account the influence of wind, based
on the simulated annealing algorithm. The algorithm considers the wind factors,
including the influence of different wind speeds and directions at the same
time on the path planning of the UAV. Firstly, An environment model is
constructed specifically for UAV bridge inspection, taking into account the
various objective functions and constraint conditions of UAVs. A more
sophisticated and precise mathematical model is then developed based on this
environmental model to enable efficient and effective UAV path planning.
Secondly, the bridge separation planning model is applied in a novel way, and a
series of parameters are simulated, including the adjustment of the initial
temperature value. The experimental results demonstrate that, compared with
traditional local search algorithms, the proposed method achieves a cost
reduction of 30.05\% and significantly improves effectiveness. Compared to path
planning methods that do not consider wind factors, the proposed approach
yields more realistic and practical results for UAV applications, as
demonstrated by its improved effectiveness in simulations. These findings
highlight the value of our method in facilitating more accurate and efficient
UAV path planning in wind-prone environments.
