20120130628 | Method for Classifying an Object as an Obstacle - A method for classifying objects into obstacles and non-obstacles for a vehicle is described. The vehicle comprises a sensor for covering the surroundings that detects stationary and moving objects in a scene in front of a vehicle. Where required, the path of the motion of the objects is tracked. The method provides one or several observers, wherein one observer classifies an object according to predetermined features and contributes to an overall classification result when there are several observers. An observer detects the path of the motion of vehicles in the surroundings of at least one stationary object and classifies the stationary object in dependence thereon. | 05-24-2012 |
