W artykule przedstawiono propozycję automatycznego systemu wspierającego pracę operatorów monitoringu. Jest on oparty na opcjonalnym narzędziu stereowizyjnym, które pozwala utrzymywać koncentrację operatora w sytuacjach wymagających rozpoznawania przez niego zagrożeń. Opracowana metoda generowania wrażeń trójwymiarowych polega na sterowaniu postrzeganą głębią dla sekwencji obrazów dwuwymiarowych (2D) lub obrazów trójwymiarowych (3D). Metoda ta może być zastosowana w systemach monitoringu 2D i 3D. Przeprowadzono eksperymenty dotyczące postrzegania jakości całego obrazu i postrzeganego zakresu głębi na oryginalnych obrazach 2D, obrazach po konwersji 2D do 3D, oryginalnych obrazach 3D i przetworzonych obrazach 3D. Zaproponowana metoda znacząco zwiększa postrzeganą głębię przy zachowaniu akceptowalnego poziomu jakości całego obrazu przy i braku zniekształceń w obszarach obserwowanych obiektów, co poprawia rozpoznawanie zagrożeń.

In this paper an automatic supporting system for monitoring operators is proposed. It is based on an optional stereovision tool, which allows to sustain the operator’s concentration in situations demanding the manual threat recognition and is based on generation of 3D impressions with the control of perception of the object depth in 2D and 3D video streams. The object depth control is considered as well in 2D monitoring systems with the novel 2D to 3D conversion scheme as in the inherently 3D monitoring systems. The experiments for examination of the overall image quality and the perceived scene depth, in order to enhance the perceived depth impressions, were conducted on: original 2D images, images after 2D to 3D conversion, original 3D images, and processed 3D images. It results from the conducted experiments that the proposed method significantly enhances the perceived scene depth range maintaining an acceptable overall image quality and no visible distortions within regions of the observed monitoring scene objects, thus it improves recognition of threats.
