Query: OpenVSLAM: A Versatile Visual SLAM Framework   In this paper, we introduce OpenVSLAM, a visual SLAM framework with high
usability and extensibility. Visual SLAM systems are essential for AR devices,
autonomous control of robots and drones, etc. However, conventional open-source
visual SLAM frameworks are not appropriately designed as libraries called from
third-party programs. To overcome this situation, we have developed a novel
visual SLAM framework. This software is designed to be easily used and
extended. It incorporates several useful features and functions for research
and development. OpenVSLAM is released at
https://github.com/xdspacelab/openvslam under the 2-clause BSD license.
