Abstract
With the rapid development of the low-altitude economy and the continuous advancement of intelligent urban airspace management,three-dimensional(3D)radio maps have significant application value in ensuring low-altitude flight safety and optimizing communication network deployment.Focusing on urban low-altitude scenarios,this paper proposes a 3D radio map construction method based on transfer learning.First,a multimodal dataset covering typical urban low-altitude flight environments is built,including informa-tion such as 3D geographic coordinates,electric field strength distributions,and building height slices.Next,by leveraging pretrained source domain weights and fine-tuning the model with target region data,effective transfer from two-dimensional(2D)to 3D domains and across regions is achieved.Finally,high-resolution 3D radio maps are generated through visualization techniques.Experimental results demonstrate that the proposed method outperforms direct training approaches in both prediction accuracy and model convergence speed,reducing Mean Squared Error(MSE),Root Mean Squared Error(RMSE),and Mean Absolute Error(MAE)by 32.7%,17.8%,and 9.5%,re-spectively,and significantly improving prediction accuracy and generalization capability.关键词
