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 sensor and allocating the text attributes to the elements; and

storing the elements and their attributes in a memory device.

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 area, forming chains of the elements by observation of predecessors and/or successors, where the predecessors mean elements occurring earlier and successors mean elements occurring later.

5. A method as defined in claim 1;

and further comprising ascertaining the text attributes to be allocated to the elements by means of an allocation table which is supplied to an input side with the attributes of the elements detected by the sensors.

6. 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 a surveillance area.

7. 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.

8. A method as defined in claim 1;

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