http://www.vision.caltech.edu/bouguetj/calib_doc/htmls/example.html，我是按照網站上的步驟一步一步來做的，在extract grid corners（提取角點）后點擊calibration之后出現了如下的情況Main calibration optimization procedure - Number of images: 13
Gradient descent iterations: 1...Warning: it appears that the principal point cannot be estimated. Setting center_optim = 0
Warning: View #1 ill-conditioned. This image is now set inactive. (note: to disactivate this option, set check_cond=0)

2...Intrinsic parameters at frame 1 do not exist
New optimization including the images that have been deactivated during the previous optimization.
Aspect ratio optimized (est_aspect_ratio = 1) -> both components of fc are estimated (DEFAULT).
Principal point not optimized (center_optim=0). Note: to set it in the middle of the image, clear variable cc, and run calibration again.
Skew not optimized (est_alpha=0) - (DEFAULT)
Distortion not fully estimated (defined by the variable est_dist):
Sixth order distortion not estimated (est_dist(5)=0) - (DEFAULT) .
說我主點不能優化，要設定在中間，不知道是什么意思，
有沒有哪位也遇到過類似的問題的啊，求助啊（網上好像沒有類似解答）
