Abstract

In a method for determining a position of at least two sensors in relation to one another, a moving object is sensed by the at least two sensors, and at least one movement variable for the moving object is determined by one of the sensors, at least said movement variable or variables derived therefrom being used jointly for determining a position of the sensors in relation to one another. The sensor network is designed to carry out a method of said kind.

First claim

1 . A method for determining an arrangement of at least two sensors in relation to one another, the method comprising:
detecting a moving object by the at least two sensors; and establishing a movement variable of the moving object by one of the sensors, wherein at least the movement variable or variables derived from the movement variable are used for determining a relative arrangement of the sensors in relation to one another.

2 . The method as claimed in claim 1 , wherein the relative arrangement of the sensors comprises at least the relative orientation of the sensors in relation to one another.

3 . The method as claimed in claim 1 , wherein the movement variable comprises at least a velocity of the moving object, the velocity at least relative to the sensor.

4 . The method as claimed in claim 1 , wherein an angle of the movement direction, established by one of the sensors relative to another sensor, is determined and used for determining the arrangement.

5 . The method as claimed in claim 1 , wherein the movement variable comprises at least a velocity of the object along the direction of a path connecting the sensor and the object.

6 . The method as claimed in claim 1 , wherein each one of the sensors in a direction of the object, the direction as observed by the sensor, is established and used for determining the arrangement.

7 . The method as claimed in claim 5 , wherein, by each one of the sensors, the direction of the object as observed by the sensor is established and detected in a manner dependent on the velocity of the object along the direction of the straight path connecting the sensor and the object, wherein the directions in which the velocity established vanishes are used for determining the arrangement.

8 . The method as claimed in claim 1 , wherein, by one of the sensors, the distance of the object from the sensor is established and used for determining the arrangement.

9 . The method as claimed in claim 1 , wherein an offset of the sensors in relation to one another is determined.

10 . A method for determining an arrangement of at least three sensors in relation to one another, the method comprising:
detecting a moving object by each pair of the at least three sensors; and establishing a movement variable of the moving object by one of the sensors of each pair, wherein at least the movement variable or variables derived from the movement variable are used for determining a relative arrangement of the sensors of each pair in relation to one another.

11 . A sensor network comprising:
at least two sensors; and an evaluation device configured to establish at least one movement variable of a moving object from data of one of the sensors and to link the at least one movement variable or variables derived the at least one movement variable for determining a relative arrangement of the sensors in relation to one another.

12 . The method as claimed in claim 6 , wherein, by each one of the sensors, the direction of the object as observed by the sensor is established and detected in a manner dependent on the velocity of the object along the direction of the straight path connecting the sensor and the object, wherein the directions in which the velocity established vanishes are used for determining the arrangement.
