Calibration Resolution is taken at 640x480 regardless of original video resolution.

Hi,
I am trying to calibrate the cameras based on videos captured in 1920x1080 resolution however the calibration parameters always shows 640x480. Is there something I am missing to do? I have followed the same steps as shown in the youtube tutorial.

Will this affect my calibration process and if yes then kindly tell me how I can resolve this issue.
Thank You.

Hello!

Based on a quick review, the size parameter there may be a historical artifact of some previous incarnations. It looks like your intrinsic parameters align with your actual resolution (the optical center is measured in pixels and seems reasonable given 1920x1080).

I think you should be good to proceed as is, though you can hard code the values in config.toml if the multicamera calibration goes awry for some reason. Searching through the code base leads me to believe this inaccuracy won't matter.... when reading frames in a video stream, the resolution is pulled from the video source itself.

I'm going to convert this discussion to an issue so that I can remind myself to clean this up when I have some more time next month.

Thanks for bringing this up and please let me know if anything else crops up during the calibration.

Regards,

Mac

Hi,

Thanks for the clarification. I am encountering another situation here. So I am using your software to calibrate my stereo camera setup for a height estimation project of train overhead cables. I have managed to get a pretty low RMSE overall and the distortions also do not look bad enough for my detection to be completely off, yet when I run my code for detection, I am getting a lot of blank spaces and distortions. Is there something you can help me out with regarding this issue?

I have attached the images of the video feed with distortions applied and the final output I am getting.

I'm sorry but I'm not sure if I understand how I can help. I don't know what "code for detection" you are referring to. If it's in another code base, I don't know where that is and I don't have the bandwidth to assist with debugging it.

If it's your code, I wish you success in tracking down the issue!

Best,
