There is PXCMImage.Rotation, not sure if it handles rotation with the projections etc too like it does with mirroring. Depending on how you're displaying the video stream, it may be just as easy to have the renderer rotate the image rather than RealSense itself.
have you found a way how to work with a rotated camera? I'm also very interested in how to get the Facetracking to work with a 90° rotated camera. If you have any good news on that topic, i'd be very happy to hear them :-)
Hi Michael! Afraid not, I ended up giving up on my more desirable system (a 90degree rotated camera) as the face tracking algorithm didnt seem to work if the camera itself was positioned at a 90degree rotation :(
