Abstract

The present invention relates to a method suitable for, within a platform, merging data from different sensors of different platforms, comprising the steps of: generating a first information entity; receiving a second information entity; processing the first and second information entities. The invention is characterized by the steps of analysing said processed first and second information entities; and performing an action event in response to the analysis.

Claims

1. Method for merging data from different sensors of different platforms within a single platform, comprising the steps of:

generating a first information entity;

receiving a second information entity;

processing the first and second information entities;

characterized by

analysing said processed first and second information entities; and

performing an action event in response to the analysis.

2. Method according to claim 1, characterized in that the step of generating the first information entity comprises the steps of:

associating a first data set generated by a first sensor with a second data set generated by a second sensor;

performing a fusion process of the associated data sets, and

generating the first information entity depending upon the performed fusion process.

3. Method according to claim 2, characterized by

transmitting a second data setup before the associating step.

4. Method according to any of claims 1-3, characterized in that the step of processing the first and second information entities comprises the steps of:

associating first content of the first information entity with second content of the second information entity; and

performing a fusion process of the associated content, so as to correlate the first and second content.

5. Method according to any of claims 1-4, characterized in

that the step of performing an action event comprises the step of:

generating a decision whether or not to generate a request,

wherein said generating depends upon said analysis, and wherein said request comprises a request for at least one additional specified complementary information entity.

6. Method according to claim 5, characterized by

transmitting the request, and

receiving said at least one additional specified complementary information entity in response to the transmitted request.

7. Method according to any of claims 1-6, characterized by

analysing said processed first and second information entities depending upon a predetermined criterion.

8. Method according to any of claims 1-4, characterized in

that the step of performing an action event comprises at least one of the steps of:

transmitting the processed first and second information entity, and

requesting at least one complementary information entity.

18. Computer programme comprising a programme code for performing the method steps of any of claims 1-10, when said computer programme is run on a computer.

19. Computer programme product comprising a program code stored on a computer readable media for performing the method steps of any of claims 1-10, when said computer programme is run on the computer.

20. Computer programme product directly storable in an internal memory of a computer, comprising a computer programme for performing the method steps according to any of claims 1-10, when said computer programme is run on the computer.

9. Method for exchanging data within a group of at least two platforms, comprising the steps of:

generating a first information entity comprising information about a first bearing from a first platform to an object within the first platform;

generating a second information entity comprising information about a second bearing from a second platform to the object within the second platform;

transmitting said second information entity from the second platform to the first platform;

characterized by

performing cross bearing of the first and second bearings to generate a position the object in space; and

transmitting data related to the generated position of the object to a platform within the group.

10. Method according to claim 9, characterized by

said transmitting the data related to the generated position of the object to a platform within the group is performed upon request.

11. Platform, comprising

means for generating a first information entity (110, 120, 130, 140);

means for receiving a second information entity (170;

999);

means for processing the first and second information entities (140, 900, 150, 160);

characterized by

means for analysing said processed first and second information entities (140, 900); and

means for performing an action event in response to the analysis (140, 900).

12. Platform according to claim 11, wherein the platform is selected from the group consisting of:

an airplane, an unmanned airborne vehicle, and a helicopter.

13. Platform according to claim 11 or 12, characterized in

that the means for analysing comprises at least one of:

means for transmitting the processed first and second information entities, and

means for requesting at least one complementary information entity.

14. Platform according to any of claims 11-13, characterized by

means for associating a first data set generated by a first sensor with a second data set generated by a second sensor;

means for performing a fusion process of the associated data sets, and means for generating the first information entity depending upon the performed fusion process.

15. Platform according to any of claims 11-14 characterized by

means for associating a first content of the first information entity with a second content of the second information entity;

and

means for performing a fusion process of the associated content so as to correlate the first and second content.

16. Platform according to any of claims 11-15, characterized by

at least one of:

means for transmitting the processed first and second information entity, and means for requesting at least one complementary information entity.

17. Communication system comprising at least two platforms according to any of claims 11-16, wherein said at least two platforms are arranged to communicate with each other.
