extrinsic parameters problem

[aa814...@gmail.com]

i dont understand how to use extrinsic parameters。when i calibrate my camera i get a matrix RRfin. but how to use it .

Maybe a bit late, but probably somebody has the same problem:

The affine transform RRfin is [x y t]. Thus, to create a rotation matrix of RRfin for frame/image f do the following:

x = RRfin(1,:,frame);

y = RRfin(2,:,frame);

T = RRfin(3,:,frame);

z = cross(x,y);

R = [x y z]
