The box displays an approximate view and sizes of person identification area projection.

 

The projection is calculated according to person identification criteria attached to a quality level assigned to camera. The criteria can be edited in a criteria-editing box of person identification area.

 

The person identification area projection is calculated on a condition of person face getting in the area at all the heights within the specified range. The identification condition becomes a presence of a  face of person of any height.

 

If there are no numerical values in the box, then the person identification area projection is missing.

The missing projection of identification area doesn't imply the failure of capacity to identify at all points of view area. To create an identification area projection all these criteria are to be observed in the whole range of heights specified in these criteria, i.e. for a person of any height

 

This tool doesn't take into account rotation of camera around its axis, shadows and lens distortion.
