issue with rosbag play about cam_lidar_calibration HOT 8 CLOSED

This problem may caused by the camera_info topic.
Check if your camera_info topic do exist the intrinsic parameter of your camera.
using rostopic echo camera_info_topic to see if this topic contains parameter rather than zero.

@aristow1 Can you give me a screenshot of your parameter? Check the parameter and make sure it is correct.For me ,the camera_info_topic's image size doesn't match the real image size cause the issue.
And this algorithm support online calibration, I personally recommend that you can calibrate online, which can not only save time on recording data, but also facilitate problem solving.

@gara-9527

the parameters are actually 0 here. should i calibrate the camera myself ? with the ros calibration package ?

Yes,if you don't need high accuracy.I think ros calibration packages is enough.
