Digital Surface Model Extraction and Refinement through Image Segmentation – Application to the ISPRS Benchmark Stereo Dataset
نویسنده
چکیده
VHR satellite images are generally used for this scope, as they almost cover any area of the planet, in particular remotely located areas. To describe the pre-event and post-event scenarios the available data are analysed and eventually fused in order to achieve the most accurate and reliable information. With respect to automatic 3D information extraction, the availability of accurate and detailed DSMs is a crucial issue for automatic building detection and subsequent damage estimation. While the acquisition of VHR stereo scenes can be planned after the event and used to model the post-event 3D scenario, VHR stereo scenes are generally not available for data acquisition before the event; on the other hand, single

متن کاملDigital surface model extraction with high details using single high resolution satellite image and SRTM global DEM based on deep learning
The digital surface model (DSM) is an important product in the field of photogrammetry and remote sensing and has variety of applications in this field. Existed techniques require more than one image for DSM extraction and in this paper it is tried to investigate and analyze the probability of DSM extraction from a single satellite image. In this regard, an algorithm based on deep convolutional...
متن کاملStereo Matching: An Outlier Confidence Approach
One of the major challenges in stereo matching is to handle partial occlusions. In this paper, we introduce the Outlier Confidence (OC) which dynamically measures how likely one pixel is occluded. Then the occlusion information is softly incorporated into our model. A global optimization is applied to robustly estimating the disparities for both the occluded and non-occluded pixels. Compared to...
