本文讨论了利用甚高分辨率(VHR)遥感图像对城市地区进行SAR光学立体成像测量的潜力和挑战。由于我们主要从几何学的角度来做这件事,我们首先分析了不同的体视图构型所期望的高度重建精度。在此基础上,我们提出了一种基于类核极搜索窗口约束的连接点匹配和三维重建策略。为了驱动匹配并确保一定的鲁棒性,我们结合了不同的手工相似性度量。在实验中,我们使用Worldview-2、TerraSAR-X和MEMPHIS传感器获得的真实测试数据。我们的结果表明,利用VHR图像进行SAR光学立体成像具有米域三维定位精度,但这些强异构多传感器数据的匹配仍然非常困难。关键词:合成孔径雷达(SAR),光学图像,遥感,数据融合,立体测量

英文摘要:
In this paper we discuss the potential and challenges regarding SAR-optical stereogrammetry for urban areas, using very-high-resolution (VHR) remote sensing imagery. Since we do this mainly from a geometrical point of view, we first analyze the height reconstruction accuracy to be expected for different stereogrammetric configurations. Then, we propose a strategy for simultaneous tie point matching and 3D reconstruction, which exploits an epipolar-like search window constraint. To drive the matching and ensure some robustness, we combine different established handcrafted similarity measures. For the experiments, we use real test data acquired by the Worldview-2, TerraSAR-X and MEMPHIS sensors. Our results show that SAR-optical stereogrammetry using VHR imagery is generally feasible with 3D positioning accuracies in the meter-domain, although the matching of these strongly hetereogeneous multi-sensor data remains very challenging. Keywords: Synthetic Aperture Radar (SAR), optical images, remote sensing, data fusion, stereogrammetry
