Abstract
A method and a device for extensive traffic situation monitoring of a road network on which vehicles can travel is provided. Remote photographs are taken by aircraft of the area to be monitored, and the images thus taken are subjected to an image-processing process to localize the roads in the road network and to recognize vehicles on them. On the basis of the detected vehicles, conclusions are then drawn about the traffic situation. A device for performing this method incorporates an evaluation center to which the data from the pictures taken by the aircraft are supplied and which has a suitable image-processing system.
Claims9
A method for extensive traffic situation monitoring of a road network on which vehicles travel, the method comprising the acts of:
- taking remote photographs of an area to be monitored via an aircraft;
- image-processing data of the remote photographs in order to localize roads in the road network and to detect the vehicles on the roads;
- and
- drawing traffic situation monitoring conclusions about a current traffic situation from the detected vehicles on the roads.
A device for extensive traffic situation monitoring of a road network on which vehicles travel, comprising:
- at least one aircraft equipped with an image-recording system for recording images of a portion of the Earth's surface on which the road network is located;
- an evaluation center receiving image-related data from the at least one aircraft;
- and
- wherein said evaluation center includes an image-processing system to which said image-related data from the image-recording system are transmitted, said image-processing system localizing the roads in the road network in the recorded images, and recognizing vehicles that are on the road network, said evaluation center drawing conclusions about the traffic situation from the vehicles recognized by the image-processing system.
