Method of determining extrinsic parameters of a vehicle vision system and vehicle vision system

In order to determine extrinsic parameters of a vehicle vision system (2-4), plural road lane markings (21-23) are identified in at least one image captured by a camera (2, 3) of the vehicle vision system (2-4). For each one of the plural road lane markings (21-23), a first set of parameters definin...

Summary:In order to determine extrinsic parameters of a vehicle vision system (2-4), plural road lane markings (21-23) are identified in at least one image captured by a camera (2, 3) of the vehicle vision system (2-4). For each one of the plural road lane markings (21-23), a first set of parameters defining an orientation and position of a line along which the road lane marking (21-23) extends in an image plane is respectively determined. A second set of parameters defining an orientation and position of a line along which the respective road lane marking (21-23) extends in a road plane is determined. A linear transformation which, for all of the plural road lane markings (21-23; 31-33), defines a mapping between the first set of parameters and the second set of parameters is identified. The extrinsic parameters are established based on the identified linear transformation, the established extrinsic parameters defining at least an orientation of the camera (2, 3).
