Automatic Extraction Experiment of DSM Data Based on Satellite Stereoscopic Images
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.
