Passengers behaviour and emotional state control is one of the standard aims of aviation security called profiling service. High error price and limited time for
passengers behaviour and emotion control requests application of technical
system for control effectiveness increase, and vibraimagesystem is ideal means for this problem solving. Results of Vibraimage
systems operation in Russian airports Domodedovo (Moscow) and Pulkovo (St.
Petersburg) were presented on the Aviation Security Conference ILA, Berlin 2008
and several security coferences in Russia.
There are two different modes for passengers behaviour screening -
personal and crowd control. Personal control has the same principals discribed
in emotional control and aura-vibraimage pages. For crowd behaviour control
vibraimage system calculates macromovements, instead micromovements. Controlled
vibration range depends only from the camera angle, camera-object distance and
movement amplitude of person. Head microvibration informatively expressed reflex
movements but it’s well known that human body macromovements expressed behavior
and emotions, too. Macromovements control has powerful advantage compared with
microvibrations, it permits crowd control. Microvibration control has powerful
advantage compared with macrovibration, it has more accurancy. High accurancy
requests more resolution of every person but this principal conflicts with the
securiy system price. Airport applications usually find comprimises between
price and security and combined both controls (personal and crowd) in different
places and are realized by Vibraimage system with different
settings. Accumulation period for macromovements registration is smaller than
for microvibration registration. It mostly determines by the speed of human body
movement and do not suppose long time movement accumulation and movement
repetition. Aggressive and nervious people performs more movements per second
and have other colors in vibraimage picture than people in normal state. It is
possible to adjust vibraimage system settings so, that normal people are
unvisible (or have real image) and only aggressive people are visible (or marked
by color) on the screen. Detail description of system settings described in
Manual. Several real vibraimages of airport passengers control are
below.
