Abstract

Researchers at the University of the Bundeswehr in Munich have developed a deep-learning system to generate 3D relief maps of cities using 2D images generated by synthetic aperture radar (SAR) signals beamed from a satellite. The researchers' SAR2Height algorithm, also trained on airborne lidar or stereo-camera images of the same cities, can render a 3D cityscape–such as this 3D relief map of Munich–with building heights accurate to 3 meters. This way, says University of Houston geosensing systems engineering professor Pietro Milillo, SAR images of a disaster area can rapidly generate data on changes in building height and therefore can yield, he says, “a map of probability of collapse of buildings.”

慕尼黑联邦国防军大学的研究人员开发了一种深度学习系统，利用卫星发射的合成孔径雷达（SAR）信号生成的二维图像生成城市的三维浮雕地图。研究人员的 SAR2Height 算法也是在相同城市的机载激光雷达或立体相机图像上训练出来的，它可以呈现三维城市景观，比如这张慕尼黑的三维浮雕地图，建筑物高度精确到 3 米。休斯顿大学地球传感系统工程教授皮埃特罗-米利洛（Pietro Milillo）说，通过这种方式，灾区的合成孔径雷达图像可以快速生成建筑物高度变化的数据，因此可以生成 "建筑物倒塌概率地图"。
