摘要
本文选择京津冀地区高分一号卫星影像作为研究对象,制定像素工厂平台下大区域高分一号正射影像制作方案。研究了利用像素工厂对大区域高分辨率遥感影像进行空三优化、正射校正、影像融合、影像镶嵌等关键技术,完成了京津冀地区高分一号正射影像的制作。精度评价结果表明,利用像素工厂能够生产在定位精度上满足要求的大区域高分一号卫星遥感影像正射影像,像素工厂在处理高分一号卫星遥感影像上具有大批量、精度高的优势。
The satellite image of the GaoFen-1 in the Beijing-Tianjin-Hebei region was selected as the research object,and a large-area orthophoto production plan under the pixel factory platform was developed in this paper.The key techniques of aero triangulation,orthorectification,image fusion and image mosaic for large-area high-resolution remote sensing images were studied by the pixel factory.The high-resolution orthophoto of GaoFen-1in the Beijing-Tianjin-Hebei region was completed.The accuracy evaluation results show that the pixel factory can produce orthophoto images of large-area high-resolution satellite remote sensing images that meet the requirements in positioning accuracy.The pixel factory has the advantages of high precision and large scale in processing high-scoring satellite remote sensing images.
