基于PCI GXL的地理国情监测整景影像纠正技术研究

Research on Image Rectification Technology of Geographical Condition Monitoring Based on PCI GXL

近几年,基础性地理国情监测蓬勃发展,所涉及的各项测绘技术已日渐成熟。本文详细介绍了PCI-GXL在地理国情监测整景影像纠正中的实际应用,针对生产过程中出现的问题进行详尽研究,并提出相应解决方法。最后,总结出一套基于已有DOM、DEM的整景影像快速、高精度纠正技术及生产流程。

In recent years,the monitoring of basic geographical conditions has been flourishing in the new era of surveying and mapping.the mapping technology involved has matured day by day.In this paper,the practical application of PCI-GXL in the rectification of geographical situation monitoring and image rectification is introduced in detail,and the problems in the production process are studied in detail,and the corresponding solutions are put forward.Finally,a set of fast and high-precision correction technology and production process based on existing DOM and DEM are summarized.
