摘要:

当我们开始考虑对大型、逼真的3D建筑场景进行建模时,有必要考虑在多边形网格模型上进行更紧凑的表示。由于大量的注释训练数据,这是昂贵的获得,我们利用合成数据来训练我们的系统的卫星图像域。通过利用合成数据,我们制定了建筑物分解作为一个应用程序的实例分割和原始拟合分解成一组原始形状的建筑物。在WorldView-3卫星影像数据集上的实验结果验证了该方法的有效性。

英文摘要:

As we begin to consider modeling large, realistic 3D building scenes, it becomes necessary to consider a more compact representation over the polygonal mesh model. Due to the large amounts of annotated training data, which is costly to obtain, we leverage synthetic data to train our system for the satellite image domain. By utilizing the synthetic data, we formulate the building decomposition as an application of instance segmentation and primitive fitting to decompose a building into a set of primitive shapes. Experimental results on WorldView-3 satellite image dataset demonstrate the effectiveness of our 3D building modeling approach.
