Abstract

A method of monitoring a surveillance area with sensors of a monitoring system has the steps of extracting from signals of the sensors elements of the surveillance area and attributes allocated to the elements, initially deriving text attributes from the attributes extracted from the sensor and allocating the same to the elements, and storing the elements and their attributes in a memory device.

Claims

1. A method of monitoring a surveillance area with sensors of a monitoring system, comprising the steps of

extracting from signals of the sensors, elements of the surveillance area and attributes allocated to the elements;

initially deriving text attributes from the attributes extracted from the sensors and ascertaining the text attributes to be allocated to the elements by means of a matrix-like allocation table, wherein the extracted attributes are provided on an input side and the text attributes are provided on an output side of the matrix-like allocation table;

allocating the ascertained text attributes to the elements;

storing the elements and their text attributes in a memory device; and

using the text attributes allocated to the elements as search terms using keywords during a search for the stored elements.

2. A method as defined in claim 1;

and further comprising comparing the stored elements with elements extracted later from the surveillance area.

3. A method as defined in claim 1;

and further comprising using the text attributes allocated to the elements as search terms during a search for the stored elements.

4. A method as defined in claim 1;

and further comprising for describing a scenario from the monitored surveillance area, forming chains of the elements by observation of predecessors and/or successors to one element of the elements in a chain, where the predecessors are elements occurring earlier than the one element in the chain and successors are elements occurring later than the one element in the chain.

5. A method as defined in claim 1;

and further comprising allocating the elements such attributes which describe global properties of a scene, monitored by the monitoring system, in the surveillance area.

6. A method as defined in claim 1;

and further comprising allocating the attributes which describe specific properties of an element extracted from a scene monitored by the monitoring system, in the surveillance area.

7. A method as defined in claim 1;

and further comprising forming the allocated attributes to describe relationships among the elements.
