A Robust and Versatile Visual-Inertial State Estimator support Omnidirectional Camera and/or Stereo Camera
VINS-OS is a real-time SLAM framework for Omnidirectional and/or Stereo Visual-Inertial Systems, modified from VINS-MONO.
Same as VINS-MONO, it uses an optimization-based sliding window formulation for providing high-accuracy visual-inertial odometry.
It features efficient IMU pre-integration with bias correction, automatic estimator initialization, online extrinsic calibration, stereo extrinsic self-calibration, failure detection and recovery.
Remove the loop detection and global pose graph optimization of VINS-MONO.
VINS-OS is primarily designed for state estimation and feedback control of autonomous drones equrped with a dual-fisheye omnidirectional stereo vison system. This code runs on Linux, and is fully integrated with ROS.

DO NOT start with a rolling shutter camera and unsync IMU (such as DJI M100 + Logitech web camera) at beginning.
We use ceres solver for non-linear optimization and DBoW2 for loop detection, and a generic camera model.
