Abstract
A system and method are provided for displaying video surveillance fields of view limitations. The system and method perform video surveillance of a given area and then geo-locate any obstacles within the area, including measuring their overall size and shape. The system and method map the size, location and shape of the objects into a database and then identify where there are video surveillance coverage gaps from each vantage point where video surveillance is being performed on the area. The system and method then determine where there are overlapping locations of blocked video surveillance (i.e., locations that are “invisible” to video surveillance). The system and method create a simulated image of the area from an orientation above the area which indentifies locations within the area that may not be seen by video surveillance from any of the vantage points where video surveillance is being performed.
