Finding Distance between Depth Camera and User's Face

[Majid_N_]

Hi,

In my project I have to know the Distance between the Depth Camera and the user's face

Is there any function or sample works that I can use in Unity to find the exact distance? I can measure the distance between the middle of two eye and using it for zoom in/out but I need the exact distance from camera and face.

Thanks

Majid

You can access the Z (depth) information of all pixels 

Refer to PXCFaceData::DetectionData::QueryFaceAverageDepth in the reference manual

If you are working in the color camera, you can project the depth camera to the color camera, and then just read the depth value at the face location.

Get the depth values projected at the color camera location with this (defined in pxcprojection.h):

PXCImage* PXCAPI CreateDepthImageMappedToColor(PXCImage *depth, PXCImage *color)
