DSM-to-LoD2: Spaceborne Stereo Digital Surface Model Refinement
Remote Sensing, 2018 A digital surface model (DSM) provides the geometry and structure of an urban environment with buildings being the most prominent objects in it. Built-up areas change with time due to the rapid expansion of cities. New buildings are being built, existing

Digital Surface Model Interpolation Based on 3D Mesh Models [PDF]
Remote Sensing, 2018 A digital surface model (DSM) is an important geospatial infrastructure used in various fields. In this paper, we deal with how to improve the quality of DSMs generated from stereo image matching. During stereo image matching, there are outliers due to mismatches, and non-matching regions due to match failure.

The Blake-Zisserman model for digital surface models segmentation [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 The Blake-Zisserman functional is a second-order variational model for data segmentation. The model is build up of several terms, the nature and the interaction of them allow to obtain a smooth approximation of the data that preserves the constant ...

A technique of digital surface model generation [PDF]
Geo-spatial Information Science, 2001 It is usually a time-consuming process to real-time set up 3D digital surface model(DSM) of an object with complex surface. On the basis of the architectural survey project of “Chilin Nunnery Reconstruction”, this paper investigates an easy and feasible way, that is, on project site, applying digital close range photogrammetry and CAD technique to ...
