摘要
在边境测图过程中,经常遇到较大面积云层问题,使航测测图无法顺利进行。能充分利用的影像资源是第一次全国地理国情普查的影像,有国产高分2号、SPOT-6、资源3号等单片卫星影像,无立体像对影像。通过对国情普查的影像分析选取,选取一试验区域进行试验,用国产高分2号卫星影像与SPOT-6卫星影像组成立体像对测制地物地貌,用Worldview卫星立体像对影像测制同一区域的地物地貌,将两种影像源组成立体模型测制的地物地貌进行比较及精度统计,说明单片卫星影像在航测测图中达到的精度。
In the border mapping process,often encounter a larger area of clouds,to map photogrammetry method.Images can make full use of resources is the first National Geographic National Census image,domestic GF2,SPOT6,ZY3 single satellite images,no stereo image.According to the national census image analysis of selection,selected test area were tested using domestic GF2 satellite images and SPOT6 satellite images composed of stereo mapping with physiognomy,Worldview satellite stereo images of the same region based image features in topography,physiognomy of the two kinds of image source composed of three-dimensional model were compared and the accuracy of measurement statistics,description of single satellite image in the measurement accuracy of the aerial map.
