Back projection matrix construction #35

Open fouad1995 opened 1 year ago

fouad1995 commented 1 year ago

Hello.

I'm asking about how do you construct the matrix of back projection ? Do you extract the homography and then use it , and if so why you use x and y inside first matrix oMatA ? I'm a little bit confused about this part and I would be pleased if you share the reference of this mathematical equation.

Thanks in advance

You could find the source code for camera calibration here: https://github.com/zhengthomastang/2018AICity_TeamUW/tree/master/Track1/2_CAM_CAL

I also have an improved method here: https://github.com/zhengthomastang/Cal_PnP

Thanks for your reply The second method provide only homography matrix not like the first method which provide [intrinsic , extrinsic and projection matrix]
