The convention of the calibration file is as follows: camx/T_cam_imu: takes a vector from the IMU frame to the camx frame. V Stereo visual inertial odometry The goal of the stereo VIO is to provide real-time accurate state estimate at a relatively high frequency, serving as the motion model for the LiDAR mapping algorithm. The entire visual odometry algorithm makes the assumption that most of the points in its environment are rigid. Each launch files instantiates two ROS nodes: Once the nodes are running you need to run the dataset rosbags (in a different terminal), for example: As mentioned in the previous section, The robot is required to start from a stationary state in order to initialize the VIO successfully. Note that for the stereo calibration, which includes the camera intrinsics, distortion, and extrinsics between the two cameras, you have to use a calibration software. First obtain either the EuRoC or the UPenn fast flight dataset.
