以高分辨率卫星影像为数据源的1∶20003D产品精度检测及分析

Accuracy Detection and Analysis of 1∶20003D Products Using High-Resolution Satellite Images as Data Sources

利用高分辨率卫星影像立体像对生产大比例尺3D产品具有航空摄影测量、全野外数字测图等方法不具备的突出优势。本文以昆明市滇中新区某片区利用WorldView-3遥感卫星立体影像采用摄影测量立体测图方法生产1∶20003D产品的项目为依托,通过采集检测点对其数学精度进行检测,验证了该技术路线在昆明地区的可行性;同时对此类产品在精度检测工作中普遍遇到的检测点采集的困难提出解决方案,并对检测数据进行深入分析,提高了精度检测工作的科学性。

Using high-resolution satellite image stereo pair to produce large-scale 3D products has the outstanding advantages that aerial photogrammetry,full-field digital mapping and other methods do not have.Based on the project of using worldview-3 remote sensing satellite stereo image and photogrammetric stereo mapping method to produce 1∶20003D products in a district in Dianzhong New District of Kunming,the feasibility of the technical route in Kunming area is verified by collecting test points to test its mathematical accuracy;At the same time,solutions to the difficulties in collection of detection points in the accuracy detection of such products,and analyzes the detection data deeply,which improves the scientific nature of the accuracy detection work.
