how to use my .bag data set for mono camera

[hessaHamad]

Hi,

am trying to use my own dataset in . bag file, contains IMU and raw images of mono cam. I followed patrick's youtube video and all my config files are set as shown there, The steps I tried: #Term 0 roscore #Term 1 rviz -d src/open_vins/ov_msckf/launch/display.rviz #Term 2 rosbag play mydataset.bag #Term 3 (no error but keep waiting for the data, it might be a topic issue) roslaunch ov_msckf subscribe.launch config:=gp dolivetraj:=true max_cameras:=1 dataset:=Test03_newcalib

and (error as shown) roslaunch ov_msckf subscribe.launch config_path:=/home/gp/workspace/catkin_ws_ov/src/open_vins/config/gp/estimator_config.yaml dataset:=Test03_newcalib bag:=Test03_newcalib.bag
