摘要
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.
Abstract
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 ster-eo images is discussed. The experimental results show that the satellite stereoscopic Images with higher resolution and the satellite ster-eoscopic Images with higher stability and higher adaptability can achieve better results for DSM automatic extraction.
