Definitions
- the invention relates to a method for interactive object recognition for a vehicle. Furthermore, the invention relates to an object recognition device. Moreover, the invention relates to a vehicle.
- ADAS Advanced Driver Assistance
- Systems perform classifications on the type of a detected object. For example, it is determined whether a detected object is a stationary or a moving object. On this basis, the behavior of the object can be predicted in the future, thus possibly giving a warning and / or avoiding possible collisions with these objects.
- classification methods can be divided into passive and active classification methods ⁇ to.
- passive classification objects are classified based on a single or multiple observations, and the choice of viewing perspectives of the objects is not affected by the classification algorithm.
- active classification future viewing perspectives are selected based on a classification ⁇ profit to improve the classification of the best possible way. That is, the sensor is moved so that the information gain is optimized for the purpose of classification.
- object types and classifi ⁇ z istsauf block are not sufficiently suitable for active and passive CLASSIFICA ⁇ insurance types.
- An example of this is a pedestrian who crosses the path of an automated vehicle. The vehicle must determine what type of object is approaching the driveway and whether the object is likely to move in front of the vehicle. To clarify these questions, one can benefit from other observations.
- the active classification it is possible to adapt or improve the type classification. That is, in this case, it can be more easily determined that the detected object is a pedestrian.
- neither active nor passive classifications can be used to determine if the pedestrian has recognized the vehicle. The pedestrian moves example ei ⁇ nem walkway toward driveway, so perhaps there is little time to react when the pedestrian does not stop in time at the edge of the walkway.
- DE 10 2014 111 023 A1 describes a method for controlling an automated vehicle, wherein a planned interaction with a road user is selected in an ambiguous traffic situation, the interaction is signaled to the road user, a reaction of the road user to the interaction is detected and a maneuver is initiated in response to the reaction of the road user.

- Some components of the object recognition device according to the invention may possibly be designed after supplementing additional hardware components, such as the actuator unit, the Sen ⁇ sor bain and the detection unit, for the most part in the form of software components. This applies in particular to parts of the pre-classification unit and the post-classification unit. In principle, however, these components can also be partly realized, in particular in the case of particularly fast calculations, in the form of software-supported hardware, for example FPGAs or the like.
- the required interfaces for example, if it is only about a transfer of data from other software components, be designed as software interfaces. However, they can also be designed as hardware-based interfaces that are controlled by suitable software.
