Abstract
A device for detecting objects in a stream of sensor image data corresponding to images of vehicle surroundings detected by a surroundings sensor of a vehicle includes: a position determination unit for determining a vehicle position, an ascertainment unit for ascertaining which object is situated in the direction of travel according to the determined vehicle position on a route of the vehicle, and a filter for filtering the sensor image data according to a location of the ascertained object in order to detect the object in the sensor image data.

1-13. (canceled)
A device for detecting at least one object represented in a stream of sensor image data, the sensor image data representing a sequence of images of vehicle surroundings of a host vehicle detected by a surroundings sensor, comprising:
- a first position determination unit for determining a vehicle position of the host vehicle;
- an ascertainment unit for ascertaining, based on the determined vehicle position on a route of the host vehicle, which object is situated in the direction of travel of the host vehicle;
- and
- a filter for filtering the sensor image data to reduce the amount of the sensor image data searched to detect the ascertained object in the sensor image data, by limiting a search for the ascertained object to a portion of the sensor image data corresponding to a location of the ascertained object in the images.
A method for detecting at least one object represented in a stream of sensor image data, the sensor image data representing a sequence of images of vehicle surroundings of a host vehicle detected by a surroundings sensor, comprising:
- determining, by a first position determination unit, a vehicle position of the host vehicle;
- ascertaining, by an ascertainment unit, based on the determined vehicle position on a route of the host vehicle, which object is situated in the direction of travel of the host vehicle;
- and
- filtering, by a filter unit, the sensor image data to reduce the amount of the sensor image data searched to detect the ascertained object in the sensor image data, by limiting a search for the ascertained object to a portion of the sensor image data corresponding to a location of the ascertained object in the images.
The method as recited in 20, wherein a relative position of the ascertained object with respect to the surroundings sensor is determined, and the sensor image data are filtered according to the determined relative position.
A non-transitory computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, performs a method for detecting at least one object represented in a stream of sensor image data, the sensor image data representing a sequence of images of vehicle surroundings of a host vehicle detected by a surroundings sensor, the method comprising:
- determining, by a first position determination unit, a vehicle position of the host vehicle;
- ascertaining, by an ascertainment unit, based on the determined vehicle position on a route of the host vehicle, which object is situated in the direction of travel of the host vehicle;
- and
- filtering, by a filter unit, the sensor image data to reduce the amount of the sensor image data searched to detect the ascertained object in the sensor image data, by limiting a search for the ascertained object to a portion of the sensor image data corresponding to a location of the ascertained object in the images.
