天绘一号卫星三线阵影像三维信息重建技术研究

Study on the Three -line CCD Image Matching of TH - 1 Mapping Satellite

三维信息重建是遥感数据处理的重要环节，主要任务是由二维影像重建真实的三维场景信息，关键技术是影像匹配。本文针对“天绘一号”卫星遥感影像数据处理，重点研究基于多基线和多特征方式的影像匹配技术和应用实践，实现基于三线阵卫星影像的高精度三维重建。

3D reconstruction is an important step of remote sensing data processing. The main task is to reconstruct real 3D geo - information based on 2D image, and the key technology is image matching. In order to realize the 3D reconstruction of TH - 1 mapping satellite image, the paper makes a study on the multi - baseline and multi - feature image matching technology and their practical application, and realizes high -precision 3D reconstruction based on three -line satellite image.
