Hi ModalAI teams,
According to the link https://docs.modalai.com/calibrate-cameras/

Could you help me to know what size of checkboard pattern has better performance.

We already known the checker board pattern could be customized.
length means square length (default: 0.038 meter), and the size means the number of inside corner (defualt:6 x 8 )
