Abstract
A method for identifying potentially hazardous or at-risk objects in the surroundings of a vehicle. The method includes detecting an area of the surroundings using at least one event-based sensor, the event-based sensor including light-sensitive pixels, and a relative change of the light intensity incident upon a pixel by at least a predefined percentage prompting the sensor to output an event assigned to this pixel. The method also includes assigning events output by the sensor to objects in the area; analyzing, for at least one object to which events are assigned, the events assigned to the object with respect to present movements of the object; and ascertaining an impending movement of the object, and/or an impending change of state, of the object from the present movements. An associated computer program is also described.
