Method for detecting navigation data for navigating vehicle, involves storing feature and position of feature as additional information to navigation data, or transmitting additional information to external processing unit

摘要

The method involves detecting feature of a road (10) and/or an environment of a vehicle by using a sensor e.g. video sensor. The feature and the position of the feature are stored as additional information to navigation data or transmitted to an external processing unit. The feature and the position of the feature are detected repeatedly for multiple vehicles such that a mean value of the detected positions is stored as the position. The external processing unit is arranged in another vehicle or in a stationary computer unit. The feature comprises a road sign (17), a tar spot (6) and a crack (7) in a road surface. Independent claims are also included for the following: (1) a computer program comprising set of instructions for performing a method for detecting navigation data (2) a computing unit for detecting navigation data of a vehicle (3) an external processing unit.
