Method and device for generating traffic data from digital aerial image sequences

摘要

the invention concerns a method and a device for collecting data from digital luftbildsequenzen.the erfindungsgemu00e4u00dfe procedures for the determination of traffic data from a sequence of partly overlapping, georeferenced digital aerial images (101, 104) in which vehicles usable routes of verkehrswegenetzes depicted, and to identify the traffic data in de r sequence of digital aerial photographs and a fahrzeugerkennung fahrzeugtracking isis that the fahrzeugerkennung only image data of first digital aerial photograph (101) of the sequence by means of a first and a second klassifikators takes place, while using the first klassifikators in the image data on the basis of potential fahrzeugobjekte trained shape and structural features to be determined, those image data.the potential fahrzeugobjekte represent segmented image data are segmented in order to receive, and through the second klassifikators in the segmented image data of the vehicles using trained color and shape and structural characteristics are determined.this procedure achieved a quality of the data, depending on the quality and resolution of the digital aerial photographs of up to 80%.the quality of the data not only allows a reliable representation of the traffic from luftgestu00fctzter automatic verkehrserfassung but also reliable forecasts on the development of traffic through simulations, with the data of the current traffic loading ized.
