摘要: 低空航路规划及基础设施是低空经济的重要研究方向。为进一步深化实景三维在城市全域数字化转型的应用领域,为低空经济发展提供三维可持续的数字底座支撑,本文针对复杂城市环境提出了一种实景三维数据支持下,基于RRT+Floyd的低空航路规划算法。以济南市东部高新区和北部建成区为试验区,开展了30、80、120、300m的低空航路规划仿真试验,并选取规划航路长度、航路节点数、航路平滑度、平均转角、最大转角5项指标,与传统RRT算法进行了对比。仿真试验结果表明,本文算法可有效提升低空空域特别是W类空域的航路规划效率和速度。

Abstract: Low-altitude route planning and infrastructure constitute important research directions in the low-altitude economy.To further enhance the application of real-scene 3D modeling in urban digital transformation and provide a sustainable 3D digital foundation for low-altitude economic growth, this paper proposes a low-altitude route planning algorithm based on RRT+Floyd, supported by real-scene 3D data, tailored for complex urban environments.Experiments are conducted in the eastern high-tech zone and northern built-up area of Jinan city, evaluating route planning at four altitudes (30, 80, 120, and 300 m).Five metrics(route length, node count, smoothness, average turning angle, and maximum turning angle)are compared with the traditional RRT algorithm.Results show that the proposed algorithm significantly improves planning efficiency and speed in low-altitude airspace, particularly in class W airspace.

Key words: low-altitude economy, low-altitude air route planning, real-scene 3D, RRT, Jinan
