Confused about commands running multiple cameras with multiple patterns for both intrinsic & extrinsic

[Ram-198]

Hi,

Currently, i am using 2 camera with 2 boards (different) for calibration. When i tried to calibrate the camera using following cmd

multical calibrate --boards charuco_multiple.yaml --cameras cam1 cam2 --camera_pattern 'data/{camera}'

i am getting following error.

line 15, in find_image_files
return [filename for filename in natsorted(os.listdir(filepath))
FileNotFoundError: [WinError 3] The system cannot find the path specified: ".\'data/cam1'"

My folder structure is

It would be great if you can help me with right cmd that i need to use to calibrate the 2 cameras (and generate intrinsic and extrinsic).

PS: i was able to to run intrisic camera calibration (could you also let me know, what cmd & folder structure needs to be used for do the extrinsic with fixed intrinsic)

Thank you in advance!!!

Thank you in advance
