Error converting video to rosbag about videoimucapture-android HOT 9 CLOSED

Your problem stems from a path error, when you are in a docker environment, the path name is different from your original path. Most importantly, ${host_name} refers to the original "/home/username". In the terminal, you can use the "tab" button to see if you can automatically complete the path; Or check the file directory that you are familiar with docker first. Good luck.

@BUG423 Can you please share how you have calibrated and converted to rosbag? I find it confusing following the instructions of README in calibration. I'm a newbie in this field. Sorry, if I'm asking some dumb questions.

I've closed this question and the reason for this issue is that I forgot to change the file name, which is a very stupid mistake. I have compiled my own calibration process, including some of my own understandings, and I have collected some successful stories of others here. But these are all Chinese, hope it helps you.

Thank you so much!

I'm having this problem. I have checked my path. But still, it's showing No such file or directory

It works now, thanks for helping me out. It seems I can't generate kalibr.yaml file. It's showing this error.

Hello, I have not encountered your problem, I suggest you start from scratch and re-do the whole process. The tutorial I provided is more detailed, maybe you missed it at some point. In addition, judging from the error message, your "target.yaml" may have a problem, you can check the file content to confirm whether there is a problem, here is my own file content (need to change according to the actual calibration board information)：

zss@zs:~/VideoIMUCapture-Android/dataset/Video/kalibr$ cat target.yaml
tagCols: 6
tagRows: 6
tagSize: 0.025
tagSpacing: 0.3
target_type: aprilgrid

@BUG423
Thanks, I have solved this problem. I forgot to add target.yaml file in the appropriate way.
