Hi!

I'm working on eye-gaze estimation using a Kinect v2.

**Focal length of IR camera** is an essential parameter involved in my equations for eye calibration. So I want to know the exact value of it. As I know, focal length of Kinect v1 is 580 (in
pixels). What's the value of

**focal length and principal point** for kinect v2?

Does the method

**MapDepthPointToCameraSpace**() use the following equations to convert image plane to camera space?

x_world = (x_screen - c_x) * z_world / f_x;

- y_world = (y_screen - c_y) * z_world / f_y;

where f_x and f_y is the focal length in x and y direction, and c_x, c_y is the x, y coordinate of principal point.

Thanks!

Michelle
