Ames Stereo Pipeline (ASP)

Documentation Status

The NASA Ames Stereo Pipeline (ASP) is a suite of free and open source automated geodesy and stereogrammetry tools designed for processing stereo images captured from satellites (around Earth and other planets), robotic rovers, aerial cameras, and historical images, with and without accurate camera pose information.

ASP produces cartographic products, including digital terrain models (DTMs, synonymous with digital elevation models, DEMs), ortho-projected images, 3D models, and bundle-adjusted networks of cameras. These data products are suitable for science analysis, mission planning, and public outreach.

Installation

Precompiled binaries are available for the stable releases and the current development build.

Precompiled binaries (Linux and macOS)

Simply download the appropriate distribution for your operating system, extract, and run the executables in the bin subdirectory.

See the NEWS.rst file for the most recent additions.

To permanently add the ASP executable subdirectory to your PATH, you can add the following line to your shell configuration (e.g., ~/.bashrc), replacing /path/to/StereoPipeline/bin with the location on your filesystem: export PATH=${PATH}:/path/to/StereoPipeline/bin

ISIS Users: Please install USGS ISIS version 4.1.0 or later if you would like to process NASA non-terrestrial images. Users wishing to process Earth images, such as Digital Globe, satellites with RPC cameras, or various frame/pinhole cameras do not need to download anything else. If ASP is installed with conda, it will install ISIS in the same environment as well, though it may not be the latest version.

Fetching ASP with conda or compiling from source

See INSTALLGUIDE.rst for details.

Documentation

The documentation is provided in PDF format, linked to above, and in HTML format at https://stereopipeline.readthedocs.io.

The documentation includes a gentle introduction to using the Stereo Pipeline, an entry for each tool, and example processing workflows for many supported sensors.

The PDF documentation is bundled with the binary distributions (named asp_book.pdf), and the ReStructured Text source files are distributed in the docs/ subdirectory.

Support and user community

All bugs, feature requests, user questions, and general discussion can be posted on the ASP support forum.

We also encourage the posting of Issues on the GitHub repo (most such items posted on the forum will typically be converted to an Issue there for the developers to work on), as well as pull requests.

Credits

ASP was developed within the Autonomous Systems and Robotics area of the Intelligent Systems Division at NASA's Ames Research Center. It leverages the Intelligent Robotics Group's (IRG) extensive experience developing surface reconstruction and tools for planetary exploration (e.g., the Mars Pathfinder and Mars Exploration Rover missions, and rover autonomy). It has also been developed in collaboration with the Adaptive Control and Evolvable Systems (ACES) group, and draws on their experience developing computer vision techniques for autonomous vehicle control systems.

See the AUTHORS.rst file for a complete list of developers.

In addition to the recommended citation, we ask that you also cite the DOI for the specific version of ASP that you used for processing. Every new release of ASP will have its own unique DOI, which can be found here.

Additional details for how to cite ASP in your published work can be found in the ASP documentation.
