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.
