Hi,Thanks for your great work! I have some questions when I read your article "AprilTag: A robust and flexible visual fiducial system". In Setion " Homography and extrinsics estimation", why the camera projection matrix P is written as Z@2XTD@BTXR7HH2GY`ZHW Y

Zhang-Qinghui commented 2 years ago

Shouldn't the camera projection matrix P be `J4VM){AJDIX~@VS}5Z$I~S Excuse me, is it something I ignored？

@Zhang-Qinghui May you drop a snippet on this part of the paper?
