ROS stereo camera calibration issues
I am currently trying to calibrate my stereo pinhole cameras. I am using the ros-noetic-camera-calibration package, a checkerboard with a 9x9 size (for 7x7 points), tried in different rooms with good lighting.
I have tried to calibrate the cameras 8 times now, all with bad outputs. I make sure every bar (x, y, size, skew) is at least green before clicking the calibrate button. The output vary between one camera being zoomed in where I can barely see 1/32 of the original image and is rotated with the other camera being just black. Sometimes the cameras become super warped where it isn’t even recognizable that it is a room.
Looking at the output parameters I can see some numbers being around 1 and some number going over 1000. It seems like some parameters are causing the bad calibration.
Is this behavior normal, should I just try more times or is there something I am doing wrong here?
I have tried a full day of calibration with no luck, any suggestions will be appreciated!
