Definitions
- the invention relates to a method for object classification for use in a vehicle with a driver assistance system.
- Driver assistance systems which, with the aid of sensor systems, detect the environment, recognize the traffic situation and assist the driver, e.g. by a braking or steering intervention or by issuing a warning.
- a braking or steering intervention or by issuing a warning.
- the correct classification of environment objects so that the driver assistance system only reacts to real obstacles.
- the invention relates to a method for classifying objects in obstacles and non-obstacles for a vehicle with an environment detection sensor, wherein the environmental detection sensor detects stationary and moving objects in a scene in front of a vehicle.
- An environment detection sensor is eg a radar sensor or a lidar sensor or a camera sensor.
- the method for the automatic classification of objects from sensor data is preferably stored on an evaluation unit in the vehicle. Since an object with a corresponding dwell time is detected several times in the detection area, the motion history of an object may be recorded (the object is tracked).
- the method provides at least one observer. In an advantageous embodiment, more than one observer contributes to the overall classification result. An observer classifies an object according to given characteristics and thus confirms the classification result of other observers if necessary.
- an observer monitors the course of movement of an object which has been recognized as a vehicle, in particular in an environment of at least one stationary object. Li depending on the stationary object is classified. For example, if a stationary object is located on the path of a preceding vehicle and the vehicle passes the object anyway, the object must be able to be moved over or under it.
- the speed profile of a vehicle in front is evaluated if the vehicle strongly decelerates strongly in the immediate vicinity of the object, this indicates that the object is an obstacle.
- an observer which describes the distribution of a mean maximum confirmation density of an object as a function of the longitudinal distance of the Unfelder initiatedssensors to the object.
- the various reflections from an object are accumulated over time and counted up. This accumulation is called confirmation density and stored in a tracker (tracker).
- This confirmation density is linked to the object position.
- the observer will be explained in more detail with reference to an exemplary embodiment and Fig. 1.
- the surroundings detection sensor detects an object in front of the sensor vehicle transverse to the road with a shape and width that could correspond to both a vehicle on the roadway (obstacle) and a sign bridge (non-obstacle).
- the average maximum confirmation density is plotted above the object distance for a gantry above the carriageway and for a vehicle on the carriageway. It forms over the distance a clear dividing line, which allows the separation obstacle / non-obstacle.
- the confirmation density is comparatively high and increases with small distance values when the object is a vehicle (obstacle on the road). If the object is a gantry bridge (non-obstruction above the carriageway), the average maximum operating density behaves in exactly the opposite way: it is comparatively low and decreases at low values.
- all accumulations which belong to an object are combined in a box on the basis of grid pattern recognition. Then the shape and size of the box is analyzed.
- an observer classifies an object based on its shape, for example by a pattern recognition method.
- a stationary, laterally extended, coherent object that expands beyond the lane boundary can thus be classified as a non-obstacle as a potential bridge or sign bridge.
- a bridge z From a jam end because a jam end concentrates within the lane boundary.
- the overall classification result is a non-obstruction.
- an observer which classifies a stationary object with a small spread or expansion as a potential non-obstacle. For example, have a Coke can or a post on a small spread compared to a vehicle. A can of soda can be overrun, so it is a non-obstacle whereas a stationary vehicle is an obstacle.
- small traversable objects are implicitly suppressed, z. For example, if the tracked area of an object is too small to be similar to a typical obstacle (eg, a vehicle), it will be suppressed. The ratio of long / width and / or the covered area are considered for the suppression. When evaluating the object area, the distance from one's own vehicle to the object may be taken into account.
- Road boundary objects may e.g. be recognized by their particular shape (guardrails) or their periodically recurring appearance (lane markings, reflectors). Only objects that are on the roadway between the road boundary objects are classified as obstacles.
