提出了一种利用QuickBird立体影像进行城市土地利用制图的方法。首先，通过在图像空间中使用二阶多项式模型进行偏差校正的RPC再生来提高地面点确定的精度。在城市土地利用制图中，使用改进的RPC从立体对生成DEM，然后生成正射影像。从正射影像中数字化道路、绿地、沃茨等城市特征，并采用立体定位的方法提取建筑物。结果表明，该方法的测图精度可达0.8m。
This paper developed an approach for urban land use mapping with QuickBird stereo imageries. The accuracy of ground point determination was first improved by RPCs regeneration using the second-order polynomial model for bias correction in the image space. In urban land use mapping, DEM was generated from the stereo pair using the refined RPCs and then an orthoimage was generated. Urban features such as roads, greenbelts, and waters were digitized from the orthoimage, and buildings were extracted using an approach of stereo positioning. The result demonstrated that a planimetric mapping accuracy of 0.8 m could be achieved.
