Camera Parameters of Rotated Frame

1.9k views Asked by At

I have a frame/image that was captured using a calibrated camera. Both sets of camera parameters (intrinsic and extrinsic) are available. I was wondering, if I flip the frame in both the horizontal and vertical directions (effectively rotating it 180 degrees), what do I need to change in the original camera parameters to obtain the correct parameters for the rotated image?

Any help is appreciated. Thanks..

The linear parts of your camera parameters will translate into a view-projection matrix. Concatenating it with a scale(-1,-1,1) transformation will give you the view-projection for the new situation (BTW, scale(-1,-1,1) == rotate(180°=pi, 0,0,1)).
