Abstract
Disclosed herein are a method and apparatus for generating a digital surface model using satellite imagery. The method includes correcting a geometric error in input satellite images, generating one or more depth maps using a stereo matching method based on the corrected satellite images, and generating a digital surface model by combining the generated depth maps and by estimating a height value for each location on the ground surface.
Claims20
A method for generating a digital surface model using satellite imagery, comprising:
- correcting a geometric error in input satellite images;
- generating one or more depth maps using a stereo matching method based on the satellite images, the geometric error of which is corrected;
- combining the generated depth maps and estimating a height for each location on a ground surface, thereby generating a digital surface model.
An apparatus for generating a digital surface model using satellite imagery, comprising:
- one or more processors;
- and
- executable memory for storing at least one program executed by the one or more processors,
- wherein the at least one program is configured to
- correct a geometric error in input satellite images,
- generate one or more depth maps using a stereo matching method based on the satellite images, the geometric error of which is corrected,
- combine the generated depth maps,
- estimate a height for each location on a ground surface, and
- generate a digital surface model.
