基于卫星立体影像的DSM数据自动提取试验

Automatic Extraction Experiment of DSM Data Based on Satellite Stereoscopic Images

先简单介绍了DSM自动提取所用到的局部匹配算法、全局匹配算法和半全局匹配算法;其次进行了基于Inpho软件半全局匹配算法的卫星立体影像的DSM自动提取试验,探讨了从传感器类型和卫星影像分辨率2个方面对卫星立体影像DSM自动提取效果的影响,试验表明,更高分辨率的卫星立体影像、稳定且更高适配度的卫星传感器的卫星立体影像对DSM自动提取能取得更好的效果。

In this paper,the local matching,global matching and semi-global matching used in DSM automatic extraction are briefly introduced.Then,the DSM automatic extraction experiment from satellite stereo images based on the semi-global matching of Inpho software was carried out,and the influence of sensor types and satellite image resolution on the DSM matching effect from satellite stereo images is discussed.The experimental results show that the satellite stereoscopic Images with higher resolution and the satellite stereoscopic Images with higher stability and higher adaptability can achieve better results for DSM automatic extraction.
