These values appear to only "stick" the first time setCamera() is called."
Was this issue recently solved? fab_cutMon, 28 May 2018 11:22:49 -0500http://answers.opencv.org/question/192444/How to compute the intrinsic parameters only (no extrinsic)http://answers.opencv.org/question/27523/how-to-compute-the-intrinsic-parameters-only-no-extrinsic/Hi there,
Is there a function in opencv to compute only the intrinsic parameters from a set of pictures ?
I do see there is one to compute both intrinsic and extrinsic. But I only want the intrinsic as I already have the extrinsic.
Hope someone can help.
Best regards,

R(r1,r2,r3)is a rotation matrix ,t is a translation matrix , k is a intrinsic matrix.I want to get H by R K T,so I use the equation (H = K(R|T).But I want to get the Homography matrix between two 2D images,and I only use r1 r2 just like H = K(r1,r2,T).Is that right??
