Theia¶

Theia is a computer vision library developed by Chris Sweeney aimed at providing efficient and reliable algorithms for Structure from Motion (SfM) and Simultaneous Localization and Mapping (SLAM) systems. The goal of this library is to provide researchers with an out of the box tool for multi-view reconstruction that can be easily extended. Many common algorithms for pose, feature detection and description, matching, and reconstruction have been implemented. All contain simple interfaces, limited dependencies, and extensive documentation.

Documentation¶

#include <theia/theia.h>

We attempt to provide sufficient documentation but often further documentation can be found in the source code itself. You will likely find the Tutorials useful as well. Additionally, (nearly) every file is covered by a unit test that can be viewed as an example use case of the various methods and classes in Theia. If you have looked at the documentation, the tutorials, the source code, and the unit tests and still have confusion please email the Theia mailing list

Finally, it should be noted that all the code in Theia is under the namespace theia, so you will have to reference that namespace in order to use functions from this library.

Acknowledgements¶

Theia was originally developed to provide a centralized code base to the Four Eyes Lab at UC Santa Barbara, but has since been expanded to an open-source project for the vision community.

The core of the original library is written by Chris Sweeney. Funding for Theia was provided by his advisors Tobias Hollerer and Matthew Turk.
