calibration

[yuan0821]

Hi, I get instinct parameters from Matlab Calibration App, and each projection error is less than 0.3.

Then I use the instinct params to do the extrinsic calibration. I getpts 14 points in the same checkboard pattern between all cameras. Then I can get the rotation matrices and translation vectors after running the following code.
the code is based on the dannce/calibration/multi-camera calibration/calibration_extrinsic_Lframe.m.

Is it already enough to do hand-labeled markers then? In my experience, the result of hand-labeled is fine.
But I just found in your public script dannce/calibration/acquire_calibration_3cam_mouse_clean.m,
you also performed STEP 6 - refine with checkerboard and STEP 7 compute the corrected world coordinates.
I am confused why you perform steps 6 and 7.

Thank you very much @davidhildebrand .

Steps 6 & 7 are optional and only need to be used if your calibration fit is subpar.
