Abstract：This paper proposed a Mercator transformation-based planning method for the online trajectory planning of cruise vehicles subject to no-fly zone constraints. By directly incorporating the planned trajectory's heading angle variation into the planning plane's higher-order derivatives, this approach explicitly characterised the energy expenditure of the trajectory without introducing dynamic constraints. The proposed method leverages quadratic programming (QP) optimisation properties to improve efficiency. It formulated the online trajectory planning problem under the QP framework, simultaneously addressing energy consumption and no-fly zone constraints. This formulation significantly enhanced computational efficiency and solution optimality. Simulation results demonstrate that the method can efficiently generate smooth, energy-efficient, and conveniently trackable trajectories while strictly complying with no-fly zone restrictions, achieving effective online trajectory planning for cruise vehicles.
