| 摘 要： | 针对高分辨率数字正射影像制作中的数字高程模型编辑环节自动化程度低、编辑效果差引起的地物变形、移位及匀光匀色环节中影像整体匀色不一致、接边痕迹明显、去雾气效果差的问题,从实际应用角度,分析了高分辨率数字正射影像图制作的关键技术。利用滨州市域9600 km2 0.2 m分辨率DMCIII航空影像数据,基于测区地理地貌特征,探讨了利用Inpho、GEOWAY CIPS、Pixel Factory等集群式影像处理系统制作1:2000数字正射影像图的技术难点及解决方法。对高分辨率航空影像的处理提出建设性意见,有助于提高今后类似项目的质量与效率,为基础测绘助力国家建设奠定基础。

| Abstract: | Focusing on the production method for mapping a high-resolution digital orthophoto and the problems that often occur in this production process, the key technology of producing high-resolution digital orthophoto maps from the practical perspective is proposed and the technical challenges and corresponding solutions are summarized using the 9600 km2 0.2 m resolution DMCⅢ digital aerial image data of Binzhou area and cluster image processing systems (such as Inpho, GEOWAY CIPS, and Pixel Factory) to produce 1:2000 digital orthophoto maps. Constructive suggestions on the acquisition and processing of high-resolution aerial images are carefully suggested. The proposals will help in improving the quality and efficiency of future projects in this field and will contribute to the fundamental surveying and mapping, which will benefit the economic development of China. |
