Method for a motor vehicle provided with a camera, device and system
View Patent ↗A method for a motor vehicle provided with a camera includes: providing, by the camera, an image representing surroundings of the motor vehicle; detecting at least one line of vehicles in the image; detecting at least one driving lane based on the at least one detected line of vehicles; detecting a state of at least one driving direction display in the image; and detecting a lane topology for the at least one detected driving lane, based on the state of the at least one driving direction display.
1. A method for a motor vehicle ( 100 ) provided with a camera ( 101 ), the method comprising:
providing, by the camera ( 101 ), an image ( 102 ) representing surroundings ( 103 ) of the motor vehicle ( 100 );
detecting at least one line of vehicles ( 104 ) in the image ( 102 );
detecting at least one driving lane ( 108 ) based on the at least one detected line of vehicles ( 104 );
detecting a state of at least one driving direction display ( 112 ) in the image ( 102 ); and
detecting a lane topology ( 114 ) for the at least one detected driving lane ( 108 ), based on the state of the at least one driving direction display ( 112 ).
2. The method as claimed in claim 1 , further comprising:
providing an item of information of the camera ( 101 ); and
detecting a position ( 119 ) of the motor vehicle ( 100 ) relative to the at least one detected driving lane ( 108 ) based on the camera information.
3. The method as claimed in claim 1 , further comprising:
detecting a displayed direction of the driving direction display based on the at least one detected line of vehicles ( 104 ), if an active state of a driving direction display ( 112 ) is detected in the image ( 102 ).
4. The method as claimed in claim 1 , further comprising:
providing a nominal lane topology from a database; and
detecting the lane topology based on the nominal lane topology.
5. The method as claimed in claim 1 , further comprising:
detecting a position of a lane marking ( 115 ) in the surroundings of the vehicle; and
the detection of at least one driving lane ( 108 ) depending on the position of the lane marking ( 115 ).
6. The method as claimed in claim 2 , further comprising:
providing an item of route information of a planned route for the motor vehicle ( 100 ); and
detecting a preferred driving lane ( 106 ) for the motor vehicle ( 100 ) based on the route information and based on the detected lane topology ( 114 ).
7. The method as claimed in claim 6 , further comprising:
the output of navigation instructions depending on the detected position of the motor vehicle ( 100 ) and depending on the preferred driving lane ( 110 ).
8. A system for a motor vehicle ( 100 ), comprising:
a camera ( 101 ) configured to provide an image ( 102 ) of the surroundings of the motor vehicle ( 100 );
a controller ( 120 ) configured to evaluate the image from the camera ( 101 );
a navigation device ( 131 ) configured to determine navigation instructions for a driver of the motor vehicle ( 100 ); and
an output device ( 132 ) configured to output navigation instructions,
the controller ( 120 ) being configured to:
detect at least one line of vehicles ( 104 ) in the image ( 102 );
detect at least one driving lane ( 108 ) based on the at least one detected line of vehicles ( 104 );
detect a state of at least one driving direction display ( 112 ) in the image ( 102 ); and
detect a lane topology ( 114 ) for the at least one detected driving lane ( 108 ), based on the state of the at least one driving direction display ( 112 ).
