Dear all,
I am trying to augment an image from a real camera to a VR world.
I came into a problem try to configure the paraview camera to the real
camera.
I know that setting camera position, view-up direction and focal point,
will give me the correct extrinsics of the camera (i.e. orientation and
displacement of the camera in the world coordinate system), but I am now
stuck at setting the intrinsics: for example my camera center is not at the
image center, therefore, by just setting up the extrinsics does not give me
the correct rendering view I need.
Is there a standard way to set up the camera so that I get correct
intrinsics?
Let's say we have K R t for my real camera, the image resolution is
[640,480]:
K = [1500 0 310
0 1400 230
0 0 1]
R = [1 0 0
0 1 0
0 0 1]
t = [0 0 0]';
Many thanks!
Li
