Abstract

The invention relates to a method for object formation for environmental modeling, wherein the processing of information of a sensor is carried out in consideration of a segmenting threshold (62) that is non-linear at least in sections. The invention further relates to a device for object formation for environmental modeling, and to a computer program, and a computer program product.

Claims

1. A method for object formation for environmental modeling, the method comprising:

processing information received from a sensor (70) with consideration for at least one non-linear segmenting threshold (56, 60, 62, 78); and

implementing the at least one non-linear segmenting threshold (56, 60, 62, 78) in a functionally adaptive manner that includes a use of different intersection levels for any of different safety and comfort functions.

2. The method as recited in claim 1, in which the at least one non-linear segmenting threshold (56, 60, 62, 78) is implemented based on a characteristic curve.

3. The method as recited in claim 1, in which the at least one non-linear segmenting threshold (56, 60, 62, 78) is implemented in a manner such that it is adapted to the situation and is based on a model.

4. The method as recited in claim 1, in which the object formation is carried out in a manner based on a cell grid.

5. The method as recited in claim 1, wherein said processing information includes sensor signal processing.

6. The method as recited in claim 1, further comprising fusing sensor data.

7. The method as recited in claim 1, which is used for a driver assistance system.

9. A computer readable storage medium storing computer readable instructions than upon execution by a computer carrying out all steps of a method as recited in claim 1 when the computer program is run on a computer or a related arithmetic unit in a device (66).

10. A computer program product that includes program code means which are stored on a non-transitory computer-readable data storage device, which program code means are operable for implementing all steps of a method as recited in claim 1 when the computer program is run on a computer or a related arithmetic unit in a device (66).

8. A device for carrying out an object formation for environmental modeling, comprising:

at least one module (68) designed to process information received from a sensor (70) with consideration for at least one non-linear segmenting threshold (56, 60, 62, 78);

wherein the at least one non-linear segmenting threshold (56, 60, 62, 78) is implemented in a functionally adaptive manner that includes a use of different intersection levels for any of different safety and comfort functions.
