Can I avoid these warnings to decrease whole processing time ?

Thanks

Hi @nukbridge. Thank you for your contribution to MC-Calib.

I have not seen this warning before. Could you please share your configuration file?

nukbridge commented 6 months ago

Here's generated configurations under 'build' directory, build.zip

Thanks

BAILOOL commented 6 months ago

Hey @nukbridge, could you please share the configuration file (i.e. *.yml) that's used to calibrate the cameras and resulted in the WARN:0@81.089] global /home/dev1/src/OpenCV/opencv-4.5.5/modules/imgcodecs/src/loadsave.cpp (239) messages?

nukbridge commented 6 months ago

Sorry, I just misunderstood your mention (I thought it's about build problem because above messages are always appeared when using MC-Calib).

Here's my configuration file used in calibration step : calib_12_take20.yml.zip

FYI: resolution of each image used in calibration is 4096 x 3000 pixels

Thanks.

BAILOOL commented 1 month ago

@nukbridge is it still the case with the latest version of McCalib? If so, please provide the sequence to see if I can replicate the warning message.
