In other words, the insertion or superposition of the additional information is changed and output depending on the situation in at least one property and / or a parameter, such as the color, size, shape and / or position. Such situation-dependent processing and display of additional information in the output image allows the viewer to perceive a changing situation clearly and intuitively.

An embodiment of the invention provides that a virtual lane is superimposed in the background and thus in the traffic environment ahead as additional information.

The invention is applicable in the vehicle for detecting and displaying a vehicle environment. Moreover, the invention is also applicable to mobile devices, such as a mobile phone, smart glasses, and / or for virtual displays, such as a projection screen and for other purposes, such as advertising, pedestrian navigation or for displays in means of transport, such as bus, train, plane and ship , applicable. In this case, the overlaying additional information is adapted to the event and / or situation.

A possible embodiment provides that the additional information is output in the background in the correct position as a function of the background. In this case, the additional information is assigned to an associated background area and / or a real object in the background in a manner optimized for the purpose of identification, and positioned in the background correspondingly close to this associated background area or to this real object for its closer specification. This represents a position-accurate and / or directionally accurate representation of the recorded environment and an intuitively detectable information transfer to the surrounding objects.

With regard to the apparatus for carrying out a method, it comprises at least one recording unit for capturing or capturing an image of an environment, wherein the image forms a background of a display, at least one processing unit for graphic processing of a captured digital image and transformation of the digital image into an output image and Creation and superposition of at least one additional information in the background and at least one output unit for outputting the additional information in the background.

1 schematically shows a device 1 for the augmented representation of at least one, in particular virtual additional information Z1 to Zx in an image forming a background H (Br), H (A) or in a sequence of such images on an output unit 2 ,

The image may be a real image Br of an environment U lying in the field of vision of the user, or a digitally recorded image Bd of the preceding environment U.

In other words, the image Br forming the background H (Br) is the real preceding environment U in one embodiment. In an alternative embodiment, which will be described in more detail here, a digital image Bd of the real preceding environment U is taken as an image and recorded in FIG an output image A which transforms the background H (A) on the output unit 2 forms.

The device 1 includes a receiving unit 3 which captures a digital image Bd or continuous digital images Bd of the environment U in the manner of a video sequence. The digital images Bd become a processing unit 4 for processing and generating a resulting output image A or a sequence of output images An supplied. The generated and output output image A in this embodiment forms the background H (A). In addition, the processing unit generates 4 virtual additional information Z1 to Zx, which are superimposed in the background H (A) or H (Br) superimposed.

The device 1 For example, it is integrated in a vehicle, not shown, where it serves to detect the environment U of the vehicle, in particular the detection of a vehicle environment ahead in the direction of travel. The vehicle includes, for example, as a receiving unit 3 at least one on-board camera, which is arranged in particular in the front area. The recording unit 3 is designed such that it receives two-dimensional or multidimensional digital images Bd with or without depth information.

The processing unit 4 is in particular a separate control unit and / or an image processing unit, which may be integrated in another control unit and / or driver assistance system.

The output unit 2 is in particular a display in the form of a screen in the dashboard area and / or a projection screen in the windscreen area. In training the output unit 2 the generated digital output image A, in which the additional virtual information Z1 to Zx is superimposed, is output as a screen in the background H (A). In training the output unit 2 as a projection screen or head-up display, the real underlying environment U forms the background H (Br) on which the virtual additional information Z1 to Zx are superimposed. The output unit 2 will be displayed below 2 called.

Hereinafter, the invention for an embodiment of the display 2 described as a screen and thus with an output image A transformed from a captured digital image Bd, which forms the (digital) background H (A). The described method for the augmented presentation of the additional information Z1 to Zx on a screen and thus in a digital background H (A) is analogous to the augmented representation of the additional information Z1 to Zx on a projection screen or head-up display applicable, where the real background H (Br) is formed by the real image Br of the preceding environment U with the real objects O1 to Oz.

The device 1 , in particular the processing unit 4 is formed so that the captured digital image Bd of the environment U in the output image A of the display 2 is transformed as a background H (A), wherein the additional information Z1 to Zx depending on the situation, in particular as a function of at least one momentary driving and / or surrounding situation changed color and / or animated in the output image An and thus changed in this superimposed output.

In other words, the additional information Z1 to Zx, which provides information and recommendations, always takes the form of an augmented representation, either in a head-up display with the real background H (Br) or in the live camera view, for example in a combined or central display with the digital one Background H (A). The augmentation takes place as contact-analogous as possible.

That is, by simple situation-dependent adaptation or modification of the additional information Z1 to Zx to be overlaid, it can appear visually highlighted in the output image An and thus against the background H (A), so that the changed or future changing situation can be intuitively perceived by the viewer.

2 shows a possible embodiment in which on the basis of, for example, recorded as a color image digital image Bd of a traffic environment representing environment U in bird's eye view as output image A and thus background H (A) a driving route ahead on the display 2 is generated and output. For example, the captured digital image Bd of this environment U was taken as a 24-bit three-channel (RGB) image with an RGB pixel per pixel, or as an infrared image in a human-imperceptible waveband.

The output image A shows in 2 a roadway 5 with two virtual lanes 5.1 . 5.2 and a vehicle F on the lane 5.1 propelled. The vehicle F is the own vehicle.

The inventive method makes it possible, depending on the situation, as additional information Z1 to Zx, at least one navigation and / or driving instruction on the roadway 5 is displayed.

2 shows as an embodiment that own lane 5.1 is used for the display of vehicle-specific, situation-dependent additional information Z1 to Zx in order to give the driver feedback about his driving behavior or to warn him against dangers, without being distracted from traffic. If one's own vehicle F is traveling too fast and has exceeded a predefined maximum permissible vehicle speed, the driver's own lane can 5.1 for example, be highlighted by a signal color or changing color.

In 2 is in your own lane 5.1 As additional information Z, a bar Z1 is superimposed with a precise trace and selectively highlighted by corresponding graphic design, such as different, in particular stepped, colorings.

The bar Z1 comprises, for example, three differently marked areas Z1.1 to Z1.3. The first area Z1.1 is marked, for example, green as a driving instruction and indicates to the viewer that the current vehicle speed is within the permissible range. For example, the second area Z1.2 is marked yellow as a warning and indicates to the viewer that the current vehicle speed while maintaining it is in a precritical range. For example, the third area Z1.3 is marked red as a further warning and signal indication and indicates to the viewer that the vehicle F can come into a critical state while maintaining the instantaneous vehicle speed.

In other words, according to the exemplary embodiment 2 becomes a curve 5.3 in the lane ahead 5.1 selectively highlighted, as in the curve 5.3 the expected due to the vehicle speed centrifugal forces are estimated as too high.

The invention makes it possible to better visualize feedback from one or more driver assistance systems, such as the speed and lane departure warning system or a navigation system, due to the augmented display of additional information Z, Z1.1 to Z1.3. In addition, there are new assistance options and applications.

Exceeding the maximum permissible vehicle speed can be determined on the basis of different sizes. For example, exceeding the vehicle speed based on a comparison of the current vehicle speed with one of the receiving unit 3 detected and / or determined by map data speed limit.

In addition to or as an alternative to identifying an exceeding of the speed limit, too high a cornering speed can be determined and, corresponding to the bar graph of the vehicle speed, correspondingly displayed with several different colors.

Additionally or alternatively to the display of the exceeding of the speed limit and / or the cornering speed on the basis of additional information Z with a corresponding overlaying of the bar Z1 with the areas Z1.2, Z1.3, as a further criterion too small a distance to a preceding vehicle V and a corresponding bar Z2, as in 3 displayed. The length and the change of the bar Z2 corresponds with the real distance or the change of the distance.

In order to reduce the energy / fuel consumption, the lane can 5.1 modified, in particular highlighted by color changes, to signal the driver whether he should accelerate, decelerate or roll out. Are in particular traffic light phases of traffic lights on the lane ahead 5.1 As is known, an improved traffic flow can be achieved and at the same time the energy / fuel consumption can be reduced by avoiding unnecessary acceleration. Without an intuitive transfer of information, such constant interaction would not be possible while maintaining the driver's attention.

3 shows in addition as further additional information Z of an oncoming vehicle F1 an augmented bar Z3, which indicates the speed, in particular relative speed, the oncoming vehicle F1 drives. For this purpose, the relative speed of the oncoming vehicle F1 is determined by means of a sequence of recorded digital images Bd and / or parameters of other sensors and determined by comparison with the own vehicle speed, whether it is an oncoming or a stationary vehicle F1.

As an alternative to the bar graph, the busy and / or unused and preceding and / or adjacent lane 5.1 respectively. 5.2 augmented and highlighted, for example, in color.

It can highlight the lanes 5.1 . 5.2 also without navigation target. In particular, the current own lane 5.1 as well as other visible lanes 5.2 Marked in different shades.

The lane marking by the bars Z1 to Z3 displayed is not only suitable for navigation, but also provides a suitable basis for an intuitive transmission of additional information, such as coloring or animation, to assist the driver and states and / or instructions and / or information To visualize driver assistance systems.

The 2 and 3 show an augmentation of the lanes 5.1 . 5.2 by the additional information Z1 to Zx in the digital output image A and thus in the background H (A) from a bird's eye view.

The following 4 . 6 to 8th show the augmentation of an underlying traffic environment from the driver's perspective in a virtual, realistic background H (A). This embodiment is also applicable to an augmentation of the forward traffic environment in a real background H (Br) in which only the additional information Z1 to Zx are augmented into the real background H (Br).

4 shows a further embodiment of the invention. In this case, the recorded image B is transferred to the output image A as a background H (A) such that in the output image A the environment U, ie real objects O1 to Oz identified in the recorded digital image Bd, such as buildings, lane boundaries, oncoming vehicle F1, unchanged or changed, z. B. opaque or partially transparent, visually alienated, especially out of focus, softly drawn, issued or becomes (in 4 . 6 to 8th - shown by dashed lines).

To assist the viewer, in particular a driver or front passenger, additional information can be superimposed on desired or relevant objects O1 to Oz as additional virtual information Z1 to Zx, which relative to the respectively associated object O1 to Oz position-accurate / -analog and perspective correct, only position-accurate / -analog or only directionally accurate / -analog and / or independent and thus freely from the background H (A) (the output image A or the translucent environment U) are displayed in the output image A.

Such a representation allows a distraction-poor, intuitive, easy-to-use and graphically appealing display 2 ,

In 4 are exemplified as objects O1 to Oz a parking garage O1, a turning vehicle O2, lane boundaries O3 shown in the output image A. The output image A may be a single instantaneous image output or a sequence of a plurality of currently captured digital images Bd in the manner of a video sequence representing the environment U in driving the own vehicle F along its own lane 5.1 shows.

This real reproduction of the environment U in the output image A can be superimposed with additional virtual information Z1 to Zx. In the 4 shown additional information Z are navigation arrows Z4 and Z5, which are determined based on navigation data of a navigation system, not shown, and displayed in the output image A. The additional information Z4 and Z5 can be displayed as 2D and / or 3D representations.

The roadway enhancements by augmentation on the basis of superimposed additional information Z1 to Zx can take place in various forms, as in 5 shown:
The lane 5.1 is the own real lane on which the own vehicle drives and which is shown in the background H (A) virtually.

The additional virtual information Z1 to Zx may be in the form of a carpet (= Z8 ( 6 ), Z9 ( 7 ), Z13 ( 8th )), a sequence of arrows (= Z4, Z5 ( 4 ), Z6, Z7 ( 6 ), Z10, Z11 ( 7 )), a hovering over the roadway cable or the like. In addition, the highlighting can be displayed to the driver both for real objects Oz in the output image A and for the virtual additional information Z1 to Zx displayed.

Safety warnings, such as a jam end or an accident site, can also be displayed by inserting additional information Z1 to Zx, for example in the form of virtual road signs Z8.1, Z8.2 (FIG. 6 ) are pre-announced in good time without distracting the driver from the traffic.

In addition, a recommendation for future driving actions can be visualized, for example around one's own lane 5.1 switch. Reasons for this may be a stagnant vehicle or a backwater of turning on their own lane 5.1 ,

Next to your own lane 5.1 can also have other lanes 5.2 be provided with additional information. In multi-lane roads can be marked, which lanes 5.1 . 5.2 are just passable and which belong to oncoming traffic. Furthermore, it can be visualized, whether currently on its own lane 5.1 can be overhauled or not. Such a representation can be supported by a highlighting of the lane markings (= Z5.3 in 3 ).

A development of the invention provides that the emphasis on own lane 5.1 can be used for navigation purposes. Especially in sharp turns 5.3 However, such a method reaches its limits since the navigation instruction is implicit and can only be recognized late.

To compensate for this disadvantage, virtual guardrails (not shown in detail) can be used as additional information Z1 to Zx whose opacity depends on the orientation of the traffic lane 5.1 is regulated relative to the vehicle F. If the vehicle F is on a straight line, it is not necessary to insert virtual crash barriers, since conventional highlighting of one's own lane 5.1 sufficient. But the stronger the direction of the leading own lane 5.1 deviates from the current direction of travel of your own vehicle F, the more opaque the guard rail will be to the driver on the upcoming corner 5.3 prepare.

Likewise, the representation of the additional information in dependence on the accuracy of a Poseschätzung done. For example, the presentation of additional information may appear more transparent with increasing inaccuracy of a position estimate. Likewise, with increasing inaccuracy of a Poseschätzung another form of visualization of additional information can be done. For example, in the case of inaccurate position estimation, navigation instructions can be displayed that do not require precise positioning, for example conventional navigation arrows.

6 to 8th show further embodiments of the invention.

Thus, it is further provided, as in 6 shown that when approaching a confusing intersection or a roundabout with multiple lanes 5.1 . 5.2 . 5.4 . 5.5 and additional carriageway 6 for other road users, eg. B. a tram, in particular the location-unaware driver by inserting additional information Z6 to Z8.2, in the form of arrows Z6, Z7, carpet Z8 and traffic signs Z8.1, Z8.2 orientation is given.

In particular, additional information Z6 to Z8.2 are also displayed if no active route guidance and corresponding recommendations for optimal route selection are displayed. Thus, with or without route guidance, the invention enables an active guidance of the own vehicle F by augmented indications of possible driving restrictions and on permitted and prohibited lanes 5.1 to 5.4 to support.

The invention thus also gives the driver recommendations for lanes without active route guidance in intersections, roundabouts, squares or other turning situations by means of directional or contact-analogous augmentation of additional information Z6 and Z7 5.4 and 5.5 into which he may enter. Similarly, as additional information Z8.1, Z8.2 prohibition notices for lanes 5.2 and roadway 6 in which the driver may not enter, for example, because it is an oncoming lane or to a lane of other road users, shown augmented. The design of the augmentation may differ, depending on whether it is a recommendation or a ban, for example in the form and / or coloring. In addition, corresponding symbols such. B. warnings are displayed as in 6 exemplified.

In a further embodiment of the invention, the driver is in turning maneuvers on an oncoming lane by appropriately augmented notes Z9 to Z13 of an augmented turn assistant (= Abbaee assistance function of the processing unit 4 ), as in 7 and 8th shown.

The driver's intention for such a turning maneuver, or at least the likelihood, is recognized, for example, by the driver starting within his current lane 5.1 without any further immediate need to brake and / or on the side of its traffic lane allocated to oncoming traffic 5.1 begin to classify (ie, for example, in Germany, the left edge of the right lane) and / or begins to blink in the direction of travel of the opposite lane.

Another easy way to detect that such a turn is imminent is based on active route guidance. As soon as the vehicle F approaches the turn-off situation, the turn-off assistant can already be activated or at least "armed" with a certain lead time.

As soon as the turn assistant has recognized with a certain probability that a turn maneuver is imminent via the oncoming lane, the traffic situation with regard to the turn-related hazard potential is evaluated and displayed augmented to the driver.

If z. B. the turning maneuver should be endangered by approaching oncoming traffic, can be warned accordingly against this danger by inserting additional information Z12.1. Also, for example, the assumed trajectory of the own vehicle F can be displayed augmented, z. B. by a transparent or opaque superimposition / display of the additional information Z9, Z10 and Z13, which are in perspective correctly on the lane surface in question, as in 7 and 8th shown.

In addition, as soon as an oncoming vehicle F1 or another obstacle occupies the virtual location of the overlays, the degree of transparency of the overlay can be increased by means of concealment, in order to support a perspectively correct display form, as in FIG 7 shown by way of example.

In addition, various symbols can be displayed such. For example, warnings (= Z11 (oncoming traffic), Z12.1 (traffic information) or a virtual stop line (= Z12) behind which there is currently no danger from oncoming traffic, see 7 , In addition, oncoming vehicles F1 can be marked and provided with augmented warnings.

As soon as a safe turning off is possible according to the turn-off assistant, for example when there is no oncoming traffic, the warnings disappear. Subsequently, various symbols can be displayed as additional information Z10, which illustrate the driver a safe turn.

Likewise, the configuration of the augmented driving trajectory can be varied, for. For example, the trajectory may be red ( 7 ) and without danger green ( 8th ) are dyed.

• – Rad- und Fußwege;
• – Rad- und Fußgängerüberwege, Zebrastreifen, Rad- und Fußgängerampeln;
• – Notfahrspuren (Emergency Lanes);
• – Fahrgemeinschaftsspuren mit Mindestbesetzungen an Mitfahrern (HOV Lanes).

In a further embodiment of the invention can generally lanes 6 be highlighted, which are reserved for certain road users, eg B .:

• - public transport, such as bus, tram;
• - cycling and walking paths;
• - bicycle and pedestrian crossings, zebra crossings, bicycle and pedestrian traffic lights;
• - emergency lanes;
• - Car pool lanes with minimum number of occupants (HOV lanes).

Especially in turning situations such lanes 5.1 to 5.4 , Roadways 5 . 6 or to be separately augmented to alert the driver to special attention and attention.

In this context, an augmented hinting is possible, for example, the driver in turn situations generally by an augmented visualization to be noted that in the present turn situation especially on pedestrians and / or cyclists, for example, especially laterally next to the own vehicle F, should be respected ,

In a further embodiment, an augmented warning can take place as soon as, for example, pedestrians and / or cyclists are detected in a turning situation laterally next to their own vehicle F. To detect itself, various sensors such. As radar, lidar, ultrasound or even corresponding cameras with the aid of algorithms of image recognition can be used.
