How can I use a camera matrix to make a cameraParameters object?

I am trying to create a cameraParameters object so that I can use the estimateEssentialMatrix() function. I have a 3x4 camera matrix. Is there a way make a cameraParameters object using the camera matrix I have?

Hi Laura,

You can try RQ decomposition for the same. In this, you will proceed by decomposing your projection matrix (camera matrix) into the product of an upper triangular one and an orthogonal one.

Follow this article for assistance: Dissecting the Camera Matrix.

Hope this helps.

Thanks.
