Definitions
- the invention relates to a method and a device for specifying the driving instructions of a navigation system, in particular for motor vehicles.
- Navigation systems in vehicles have been widely used in recent years.
- the navigation data provide a global view of the driving environment from which the behavioral instructions are generated (e.g. "turn right now”).
- the position of the vehicle in the map data is also often not known with sufficient accuracy. As a result, the exact time of the driving instructions can in many cases not be selected correctly by the navigation system.
- GPS position and map material information that is available to the navigation system (GPS position and map material), as well as vehicle data (odometry) such as wheel speeds, speed, steering angle and the like have been used.
- vehicle data odometry
- the inaccuracy of the position determination with respect to the actual driving environment can be up to 50m.
- camera systems for driver assistance functions such as lane detection or monitoring, for blind spots and lane changes, for obstacle warnings, for pre-crash sensing, for traffic sign recognition or the like will also play an important role.
- these camera systems allow a precise local view of the driving environment.
- DE 199 37 489 A1 discloses the combination of an environment detection with a GPS system.
- the generation of driving instructions is not disclosed, nor is the effect of image processing on them.
- No. 5,922,036 AI also discloses a method in which the number of lanes and the number of one's own lane are determined by means of a camera. Driving instructions are then generated from this together with a GPS-supported navigation system.
- a disadvantage of this method is the determination of the number of lanes, since this can sometimes not be clearly determined by the perspective projection. There is also the risk of confusing the lane markings of the outer lanes with e.g. the guardrail. Another disadvantage is the possible one
- a junction detection system that is based on the measurement of the widening of a lane marking and additionally or alternatively the widening of the lane. This is described in great detail.
- a track position detection which, however, does not recognize the number of tracks as in US 5,922,036 AI, but bypasses the main disadvantage and uses the type of marking. If one line is solid, the other is dashed, the vehicle is on an edge lane. If both lines are dashed, the vehicle is in a middle lane.
- technical measures must be specified to achieve the following goals: preparation and improvement of the driving instructions and improvement of the timing of the driving instructions.
- the present invention advantageously makes an important simplification.
- the lane recognition and the driving instructions generated from it are essentially based on the recognized type of lane marking.
- a lane model in particular is not required, which advantageously saves considerable computing time.
- driving instructions can be specified essentially on the basis of turning arrows • recognized by the camera system, stop lines, crosswalks, etc. of one's own and / or on an adjacent lane.
- zebra crossings, arrows, stop lines, intersections, road junctions, traffic lights, and the like have a defined longitude and latitude, which advantageously allow a precise comparison with a corresponding entry in a map set, as a result of which a motor vehicle is more accurate can be localized and consequently navigated more precisely.
- the position of a crossing vehicle in the image of the camera gives an indication of the exact one Position of your own vehicle relative to a distinctive road event entered in the navigation maps or data, such as intersections, junctions, exits or the like.
- driving instructions can essentially be specified on the basis of traffic signs, traffic lights, oncoming and cross traffic, etc. recognized by the camera system, ie, when listed, this advantageously allows driving instructions to be generated depending on the current traffic situation.
- driving instructions can be generated that relate to the type of lane currently being traveled (straight ahead, right turn, left turn, etc.).
- driving instructions can be generated that relate relatively to the lane number currently being used (e.g. try to change two lanes to the left).
- unnecessary driving instructions can advantageously be suppressed for the first time. For example, if the vehicle is already in a correct lane, or if the type of lane marking does not allow maneuvers, ie no "please turn if possible" with a solid center line or the like.
- driving instructions or reminders of a previous driving instruction can be issued for the first time as soon as a change in the lane marking allows a driving maneuver (eg "The median now allows turning” or the like) and / or as soon as the type of lane marking changes a planned maneuver allows or requires (eg "Now right on the
- the invention also relates to a device for carrying out the methods described above, namely a navigation system which comprises:
- a camera system that detects the driving environment, especially in the front area, of the motor vehicle
- a computing unit in which driving instructions are generated on the basis of prepared map data, a position determination of the motor vehicle e.g. by means of GPS, odometry and / or the like, and the evaluation results of the image data recorded by the camera system.
- the evaluation unit is part of the computing unit, the image data from the camera system preferably being transmitted to the evaluation unit via an LVDS connection.
- an evaluation unit is provided in the camera system, which partially or completely (pre-) evaluates the captured image data, with partially or fully evaluated image data using a CAN, RS232, MOST, LIN or other suitable connection to the computing unit be transmitted.
- the present invention is based on the knowledge of making use of the precision of the driving instructions of a navigation system, in particular for motor vehicles, of a camera system, for example the type of marking a lane (solid line, dashed line, change from solid line to dashed and vice versa) reliably detect.
- the invention thus advantageously allows the position of a motor vehicle to be compared to markings stored in map data, such as lane changes, arrows, crosswalks, traffic lights, etc., to the map data, and thus more precise navigation than is known in the prior art.
- a camera system consisting of a camera and an image processing computer is mounted, for example, on the windscreen in the area of the interior mirror.
- the image area includes the course of the road in front of the vehicle with a total horizontal viewing angle of approx. 50 °.
- the camera system recognizes its own lane, the type of lane marking, the number of existing lanes, turning arrows, stop lines, traffic signs, crosswalks, traffic lights and / or cross traffic, etc.
- the information is sent as a message e.g. fed into the CAN bus, ie into the network hardware for data transmission in the vehicle. These messages / data are read out of the CAN by a navigation system and converted into improved driving instructions.
- the system typically consists of: - a navigation system, which processes the map data, determines the position of the vehicle, for example using GPS and odometry, and generates driving instructions; - A camera system that detects the driving environment in the front area of the vehicle; such as
- the navigation system must have an arithmetic unit, the camera system can have its own arithmetic unit.
- the following cases are alternatively or cumulatively conceivable: - the camera transfers the image data to its own computing unit, the image data is evaluated on this computing unit and the results of the evaluation are transferred to the navigation computer using suitable hardware (for example CAN, RS232, MOST, LIN) , ....); - The camera transfers the image data to the navigation computer (e.g. via LVDS), the image data is evaluated on the navigation unit and incorporated into the results in the driving instructions.
- the camera detects turn arrows on its own lane and notifies the driver of a change of lane if the turn arrow (eg straight arrow) does not match the upcoming turning maneuver ("turn right").
- turn arrow eg straight arrow
- a detection of the change in the type of lane marking e.g. from a solid to a dashed line
- traffic signs e.g. stop sign, observe the right of way, priority street, ...
- motorway exits are not recognized by widening the lane marking or the lane itself, but advantageously simply by changing from solid to dashed lines.
- a further developed version of the system does not explicitly recognize departures, but the driving instruction can be generated simply because the type of lane marking is dashed at a certain point in time (as long as the type is solid, the instruction is suppressed). If a change of the right lane marking from a solid line to a dashed line is recognized on a freeway, the instruction "now turn right" can be given at this point.
- this change is recognized approximately 25 to 50 m in front of the vehicle and the driving instructions are generated even earlier.
- all markings can be used which give an indication of an intersection area. These are turning arrows, stop lines, traffic signs, crosswalks and traffic lights.
- a comparison can be made with the information from the map data. For example, the position of crosswalks is available in map data.
- intersection area Another indication of an intersection area is the detection of cross traffic.
- the present invention advantageously minimizes the output of unnecessary and / or misleading driving instructions from a navigation system to the driver of a motor vehicle.
- the current position of the vehicle in the map data of a conventional navigation system can often only be determined to within 50m using GPS (shadowing) and odometry.
- the camera-based recognition of characteristic features such as turns, zebra stripes, stop lines, traffic signs, etc., which are recorded in the map data, enables the vehicle position to be compared in the map data for the first time, thereby making the timing of the driving instructions much more precise.
- the present invention thus advantageously reduces the risk of accidents in road traffic.
