Get camera matrix after setAlphaScaling in the depth node.

mrvladimir

Hello,

I would like to get rid of black borders/get better depth using the stereo node's setAlphaScaling function. After setting the alpha value, how do I get the new intrinsic camera matrix?

I currently use the ros bridge function calibrationToCameraInfo. Is there an api in the ImageConverter I could call to get the CameraInfo with the alpha scaling factor included?

Thank you,

Vladimir

Hi mrvladimir
Have you checked this opencv function for new camera matrix?

Hope this helps,

I'm using that function as a work-around and assuming the result of getOptimalNewCameraMatrix is exactly the same as what the depthai setAlphaScale function does.

However it would be nice if I didn't have to rely on that assumption.
