bagcreator or record directly a ros bag ? #643

Closed mahammadirfan closed 10 months ago

mahammadirfan commented 10 months ago

Hi, I want to calibrate stereo-inertial, and have few questions: 1) I have a ROS installed system with the sensors, Do i need to start the bagcreator and convert it into rosbag file or i can directly record everything in a rosbag file ?

Thanks!

I have one more question to ask :
2) I am calibrating dji m300 drone.....it has inbuilt stereo cameras...for now i am using just front....with its own IMU....do i have to check and set IMU + camera cordinate system to any specific for kalibr ?

Thanks!

The wiki describes how to do this. If you can directly record into a rosbag then there is no need to convert image data into a rosbag data. You need to ensure they are right handed coordinate systems and use the correct ROS standard units for the IMU (rad/s and m/s^2).
