Fully Automated DEM Generation using Satellite Imagery

High resolution and accurate Digital Elevation Model (DEM) generation from satellite imagery is a challenging problem. In this work, a multiview stereo reconstruction framework is proposed that is applicable to non-stereoscopic satellite images which may have been captured by different satellites. Given a cross-platform satellite image archive, the images are first geolocation corrected with respect to each other using a fully-automated processing pipeline that applies sparse feature matching and bias correction of Rational Polynomial Coefficient (RPC) camera models.
