Method for Automatically Classifying Moving Vehicles
First Claim
1. A method for classifying a moving vehicle comprising the following method steps:
- recording at least one image of a vehicle by means of a camera and determining position and perspective orientation of the vehicle,generating from three-dimensional vehicle models which are stored in a database rendered two-dimensional views in positions and perspective orientations in which the three-dimensional vehicle model could be perspectively orientated along an anticipated movement path of the vehicle relative to the camera,comparing the at least one recorded image of the vehicle with the rendered two-dimensional views of the stored three-dimensional vehicle models and finding the two-dimensional view with the best match, andclassifying the recorded vehicle with the three-dimensional vehicle model which best matches one of the two-dimensional views.

Abstract
The invention is directed to a method for classifying a moving vehicle. The object of the invention is to find a novel possibility for classifying vehicles moving in traffic which allows a reliable automatic classification based on two-dimensional image data. This object is met according to the invention in that an image of a vehicle is recorded by means of a camera and the position and perspective orientation of the vehicle are determined therefrom, rendered two-dimensional views are generated from three-dimensional vehicle models which are stored in a database in positions along an anticipated movement path of the vehicle and are compared with the recorded image of the vehicle, and the vehicle is classified from the two-dimensional view found to have the best match by assignment of the associated three-dimensional vehicle model.
