What is the focal length (fx and fy) and the camera principal points (cx and cy) of the Intel RealSense ZR300? I tried looking at the specs, but couldn't find it (https://click.intel.com/media/ZR300-Product-Datasheet-Public-002.pdf). Thanks.

The documentation of the RealSense SDK For Linux (an SDK that was made specially for the ZR300) describes fx, fy and associated pixel-related values such as the principal points.

A couple of years ago, someone did tests on an Intel Euclid (a candy-bar sized PC containing a ZR300) and posted their results for fx, fy, cx, cy, etc.

Also please note that the RealSense forum has moved to a new location, so please post future questions there. Thanks!
