For automatization are using a lot of modern technologies for example machine vision. Measure the distance from the object (face) to the camera, capture a reference image and note down the measured distance. Distances were calculated using the equations described above and compared to the real object distances using a regression analysis. Measure the object (face) width, make sure that measurement units are kept for reference image and object (face) width.
