随着无人飞行器的大范围普及,针对其场景理解的技术和应用也变得越来越重要。论文采用BOO原理建立语义标注模型,利用地图软件中显示的瓦片金字塔技术,结合事件识别领域提供的训练数据集和测试数据集,提出了一种新的语义分层方法。实验仿真证明该方法能够使无人机在不同高度拍摄的场景中识别出相应的景物。 As the popularity of UAVs increases, the technology and applications for understanding their scenes become more and more important. In this paper, the semantic annotation model is established by using BOO principle, and a new semantic stratification method is proposed by using the tile pyramid technology displayed in map software and the training dataset and test dataset provided in the field of event recognition. The experimental simulation proves that the method can make the UAV recognize the scene in the scenes shot at different heights.
