Method, device, map management device and system for precise location tracking of automobiles in the surrounding environment

摘要

The present invention relates to a method for precise positioning of a vehicle 50 in a surrounding environment 12, comprising the following steps in a device 2 in the vehicle 50: a vehicle by means of at least one camera 4 Capturing the image sequence of the surrounding environment 12 of 50, detecting and classifying the objects 28 by the evaluation unit 5 in the captured image sequence, the objects for the vehicle 50 ( 28) by the evaluation unit 5, defining a section 13 with a predetermined size and a predetermined boundary 14-17 in the surrounding environment 12, the defined section ( 13) allocating objects 28 to the determined object locations within section 13, identifying lane 22 of vehicle 50 located within section 13, location and object information of objects 28, definitions Transmitting section information, lane information, and time information for the section 13 to be transferred by the transmission device 6 to the map management device 3. Data is received from the map management device 3 and compared with the digital map 60. Subsequently, the corresponding surrounding environment map is transmitted to the device 2, compared with the surrounding environment data in the defined section 13, and the vehicle 50 is located. The invention also relates to a device 2, an associated map management apparatus 3 and an associated system 1.
