ROS2 Initialzation error

[VivekMangeUD]

Hello

I am facing initialization error when testing Openvins on my Laptop Ubuntu 22. Even after moving in random direction and Jerk motions, Its not able to initialize openvins. I have attached a recording for the same. I have also shared the launch file to run the node. I tried changing the below 3 varaibles in the estimator config file but still same results

init_window_time: 2.0 # how many seconds to collect initialization information init_imu_thresh: 1.5 # threshold for variance of the accelerometer to detect a "jerk" in motion init_max_disparity: 10.0

I am also facing issue visualizing the messages on terminal even with verbosity:= DEBUG

ros2 launch ov_msckf ros2_aqua2_subscribe.launch verbosity:=DEBUG [INFO] [launch]: Default logging verbosity is set to INFO [INFO] [run_subscribe_msckf-1]: process started with pid [176172]
