How to make depthbuffer, scenedepth buffer visible to CPU
We are working on a VR project with RGBD camera. In order to calibrate our depth camera with unreal scene virtual camera, we need to read out the depthbuffer (the calibration process is done by aligning depth image from our depth camera with depth buffer (or GBuffer depth channel) from unreal virtual camera, since the virtual environment has same geometry info as in real world).
Long words in short: we need to pass scene depth buffer to openCV for calibration.
However, we can't find a way to make depth information visible to CPU. So any suggestion will be greatly appreciated.
