摘要
通过分析"北京一号"小卫星成像特点及数据获取时的几何特性,建立了利用"北京一号"小卫星影像进行建筑物高度测量的模型,并对北京市望京地区建筑物高度进行了测量试验和实地验证。结果表明,用"北京一号"小卫星影像能获得较为准确的建筑物高度信息,并为城市遥感应用提供辅助和支持。
In this paper, a model that can be used to estimate building height is set up on analysis of the geometric characteristics of Beijing-1 small satellite in imaging and data acquisition procedure. Using this model, heights of the buildings in Wangjing district in Beijing are estimated with the Beijing-1 small satellite panchromatic image. Comparison with data acquired in field experiment show that with Beijing-1 small satellite image, building heights can be measured in sub-pixel precision , and great support of this data to remote sensing applications in the cities can be expected.
