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.
@gara-9527 im having the same issue, and i checked rostopic echo camera_info_topic and i get parameters. but i still have the same issue
@talhasu did you get this solved ?

@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.
一切正常,直到我运行 rosbag play -l --pause mybag.bag。我收到以下错误。如果您知道解决方法,能否请您看一下并回复我
how can you deal it ? i meet the same problem
Hi @duduzai2019, Did you solve this problem?
Everything works fine until I run rosbag play -l --pause mybag.bag. I am getting the following error. Could you please take a look and reply me back if you know a way around
