摘要: 针对机场净空监测DSM生产需求,本文基于高精度控制资料对高分七号(GF-7)卫星影像进行立体匹配,得到DSM数据,但高层、超高层建筑匹配效果不佳,人工立体编辑工作量较大,因此对GF-7与资源三号(ZY-3)卫星影像进行联合区域网平差,采取多视准核线影像匹配、全局优化遮挡检测与视差空洞修补等技术,立体匹配得到高精度DSM数据,有效提取出高层、超高层建筑,为机场净空监测提供了基础空间数据。

Abstract: According to the DSM production requirement of airport clearance monitoring, the DSM data is obtained by stereo matching of the GF-7 satellite image based on the high-precision control data in this paper. The matching effect of high-rise and super high-rise buildings is not good, and the manual stereo editing workload is large. Joint block adjustment is performed on the satellite images of GF-7 and ZY-3, and technologies such as multi-horizon epipolar image matching, globally optimized occlusion detection and parallax hole repair are adopted to obtain high-precision DSM data by stereo matching. The high-precision DSM can effectively extract high-rise and super-high-rise buildings, and provide basic spatial data for airport clearance monitoring.

Key words: joint block adjustment, multi-horizon epipolar image matching, globally optimized occlusion detection, parallax hole repair
