Definitions
- the present invention relates to a method, a computer program with instructions and a device for reducing occlusions by a virtual image of a head-up display of a means of transportation.
- the invention also relates to a head-up display for a means of transportation, in which such a method or such a device is used.
- a head-up display also referred to as a HUD, is understood to mean a display system in which the viewer can maintain his line of sight, since the content to be displayed is displayed in his field of vision. While such systems were originally used mainly in the aviation sector due to their complexity and costs, they are now also being installed in large series in the automotive sector.
- Head-up displays generally consist of an image generator, an optics unit and a mirror unit.
- the image generator creates the image.
- the optics unit directs the image to the mirror unit.
- the image generator is also often referred to as the imaging unit or PGU (Picture Generating Unit).
- the mirror unit is a partially reflective, translucent disc. The viewer sees the content displayed by the image generator as a virtual image and at the same time the real world behind the pane. In the automotive sector, the windshield is often used as a mirror unit, and its curved shape must be taken into account in the display. Due to the interaction of the optics unit and the mirror unit, the virtual image is an enlarged representation of the image generated by the image generator.
- a liquid crystal display (LCD: Liquid Crystal Display) with backlighting for the imaging unit is currently usually used for head-up displays used.
- Displays based on OLED technology OLED: Organic Light Emitting Diode; organic light-emitting diode
- DMD Digital Micromirror Device; digital micromirror component
- DE 102015 215 180 A1 describes a head-up display for a vehicle.
- the head-up display includes a display device for emitting light with an image generation unit, and an image control unit for driving the image generation unit.
- a reduced brightness is set in areas of the display device depending on the viewing direction of a user. This enables a reduction in the energy consumption during image generation. However, it does not prevent the user from being dazzled when the ambient brightness is low if the areas of the display device whose brightness is not reduced are set too bright.
- a general approach to solving this problem is to avoid larger, full-surface bright areas on the LCD display and to build up the virtual image from thin lines instead of using filled areas.
- the virtual image can be broken down into small rectangles, so-called tiles, which are each checked for their transparency.
- the transparency serves as a measure for the covering area of the tile.
- the transparency may only be a quarter of the maximum permissible concealment area. This takes into account that the bright area could be divided into four tiles in the worst case.
- a method for reducing occlusions by a virtual image of a head-up display of a means of transportation comprises the steps:
- a computer program comprises instructions which, when executed by a computer, cause the computer to carry out the following steps for reducing occlusion by a virtual image of a head-up display of a means of transport:
- the term computer is to be understood broadly. In particular, it also includes control devices, controllers, embedded systems and other processor-based data processing devices.
- the computer program can be provided for electronic retrieval, for example, or it can be stored on a computer-readable storage medium.
- a device for reducing occlusions by a virtual image of a head-up display of a means of transport has:
- dividing module for dividing an image to be displayed into a plurality of sub-areas, the sub-areas being trapezoidal and varying in size over the area of the image to be displayed;
- a warning module for outputting a warning signal when the certain concealment area exceeds a permissible size for at least one of the partial areas.
- the image to be displayed is broken down into trapezoidal tiles whose size varies within the image.
- the dividing axes do not run horizontally and vertically through the field of view. Instead, the subdivision corresponds to the visual axes and thus to the proportions of the perceived image.
- a transparency of the partial areas is considered as a measure for the concealment area.
- Transparency is a measure that is easy to determine for how large the percentage of the covered area is within the respective partial area.
- a check is made as to whether the concealed area determined for two or more adjacent partial areas exceeds a permissible size.
- the bright area that leads to masking is distributed over four sub-areas.
- the permissible size of the concealed area within a sub-area is selected in such a way that this situation is taken into account.
- an examination of neighboring sub-areas shows that the permissible size of the concealed area has not been exceeded there and that the concealment is tolerable overall, there is no need to issue a warning signal.
- the partial areas have a decreasing size from an edge area of the image to be displayed to the horizon and/or to a vanishing point.
- an inclination of the means of transportation is determined in order to determine the horizon.
- Determining the vanishing point determines a viewing direction of a viewer.
- the position of the horizon can easily be determined from the inclination of the means of transport, which can be detected, for example, by means of gyroscope sensors.
- the vanishing point can in turn be easily determined from the viewing direction of the viewer, in particular the vertical viewing direction.
- the viewing direction of the observer can be recorded with an interior camera, for example.
- At least one measure for reducing the concealment is carried out.
- at least one pixel that causes the occlusion can be shifted.
- the image element can be made up of thin lines or simply displayed as an outline.
- display of picture elements in the area of the horizon or in the area of the vanishing point is suppressed.
- the horizon itself or the vanishing point is completely omitted from the display of picture elements.
- the end of a traffic jam for example, can appear very small and can be easily covered.
- a method according to the invention or a device according to the invention is preferably used in a head-up display for a means of transportation, eg a head-up display for a motor vehicle.
- a head-up display is characterized by increased safety for the driver, since the covering of relevant objects in the driver's field of vision is reduced or completely avoided.
- FIG. 1 schematically shows a head-up display according to the prior art for a motor vehicle
- Fig. 2 shows a division of an image to be displayed into rectangular patches
- FIG. 4 schematically shows a method for reducing occlusions by a virtual image of a head-up display of a means of transportation
- FIG. 5 schematically shows a first embodiment of a device for reducing occlusions by a virtual image of a head-up display of a means of transportation
- FIG. 6 schematically shows a second embodiment of a device for reducing occlusions by a virtual image of a head-up display of a means of transportation.
- the head-up display has a display device 1 with an imaging unit 10 and an optical unit 14 .
- a beam of rays SB1 emanates from a display element 11 and is reflected by a folding mirror 21 onto a curved mirror 22 which reflects it in the direction of a mirror unit 2 .
- the mirror unit 2 is shown here as a windshield 20 of the motor vehicle. From there, the bundle of rays SB2 arrives in the direction of an eye of an observer 3.
- the viewer 3 sees a virtual image VB, which is located outside the motor vehicle above the hood or even in front of the motor vehicle.
- the virtual image VB is an enlarged representation of the image displayed by the display element 11 due to the interaction of the optics unit 14 and the mirror unit 2 .
- a speed limit, the current vehicle speed and navigation instructions are shown here symbolically.
- the eye of the viewer 3 is within an eye box 4 indicated by a rectangle, all elements of the virtual image VB are visible to the viewer 3 . If the eye of the viewer 3 is outside of the eyebox 4, then the virtual image VB is only partially visible to the viewer 3 or not at all. The larger the Eyebox 4 is, the less restricted the viewer is when choosing his seating position.
- the curvature of the curved mirror 22 matches the curvature of the windshield 20 and ensures that the image distortion is stable across the entire eyebox 4.
- the curved mirror 22 is rotatably supported by a bearing 221 .
- the rotation of the curved mirror 22 made possible by this enables the eyebox 4 to be moved and thus the position of the eyebox 4 to be adjusted to the position of the viewer 3.
- the folding mirror 21 serves to ensure that the path covered by the beam of rays SB1 between the display element 11 and the curved mirror 22 is long, and at the same time the optics unit 14 is still compact.
- the imaging unit 10 and the optics unit 14 are separated from the environment by a housing 15 with a transparent cover plate 23 .
- the optical elements of the optical unit 14 are thus protected, for example, against dust located in the interior of the vehicle.
- An optical film or a polarizer 24 can also be located on the cover plate 23 .
- the display element 11 is typically polarized and the mirror unit 2 acts as an analyzer.
- the purpose of the polarizer 24 is therefore to influence the polarization in order to achieve uniform visibility of the useful light.
- a covering arrangement 25 arranged on the covering pane 23 serves to reliably absorb the light reflected via the boundary surface of the covering pane 23, so that the viewer is not dazzled.
- the light from another interfering light source 5 can also reach the display element 11 .
- the polarizer 24 can also be used to reduce incident sunlight SL.
- FIG. 2 shows a subdivision of an image to be displayed into rectangular sub-areas K.
- the resulting virtual image VB and the sub-areas K are shown from the perspective of the driver of a means of transportation 50.
- the sub-areas K are rectangles of uniform size. It can be clearly seen that the partial areas K in the area of the vanishing point FP or the horizon H cover a larger perceived area of the environment than partial areas K at the edge of the image. For example, the partial area extends K at the vanishing point over the entire width of the street, while the sub-areas K at the bottom only cover a fraction of the street.
- FIG. 3 shows a subdivision of an image to be displayed into trapezoidal partial areas K of different sizes.
- the resultant virtual image VB and the sub-areas K as seen by the driver of a means of transportation 50 are again shown.
- the sub-areas K decrease in size from the edge of the image to the vanishing point FP. Because the perceived size of an object varies with the distance of the object, the patches K are small in those areas of the image that overlap distant objects. On the sides of the image, the perceived objects are closer, so the partial areas K can also be larger.
- the area of the vanishing point FP is completely left out of the display of picture elements, which is indicated by the central rectangle.
- FIG. 4 schematically shows a method for reducing occlusions by a virtual image of a head-up display of a means of transportation.
- a horizon and/or a vanishing point are determined S1.
- an inclination of the means of transportation can be determined beforehand.
- a viewing direction of an observer can be determined in order to determine S1 the vanishing point.
- an image to be displayed is divided into a plurality of patches S2.
- the partial areas are trapezoidal and their size varies over the area of the image to be displayed.
- the partial areas preferably have a decreasing size from an edge area of the image to be displayed to the horizon and/or to a vanishing point.
- Coverage areas are determined S3 for the individual partial areas. In this case, for example, a transparency of the sub-areas can be considered as a measure for the concealed area. Finally, it is checked S4 whether the concealed area determined exceeds a permissible size for at least one of the partial areas. If this is the case, a warning signal is issued S5. Before issuing a warning signal can it can optionally be checked whether the coverage area determined for two or more adjacent partial areas exceeds a permissible size. Finally, in response to the warning signal, at least one measure for reducing the concealment is carried out S6. A display of picture elements in the area of the horizon or in the area of the vanishing point is preferably suppressed.
- FIG. 5 shows a simplified schematic representation of a first embodiment of a device 30 for reducing occlusions by a virtual image of a head-up display of a means of transportation.
- the device 30 has an input 31 via which an image B to be displayed is received.
- Information N, BR can also be received via the input 31, from which an evaluation module 32 can determine a horizon and/or a vanishing point.
- an evaluation module 32 can determine a horizon and/or a vanishing point.
- an inclination N of the means of transportation can be evaluated.
- a viewing direction BR of an observer can be evaluated.
- a dividing module 33 is configured to divide the image B to be displayed into a plurality of patches.
- the partial areas are trapezoidal and their size varies over the area of the image B to be displayed.
- the partial areas preferably have a decreasing size from an edge area of the image B to the horizon and/or to a vanishing point.
- a processing module 34 is set up to determine concealment areas for the individual partial areas. In this case, the processing module 34 can, for example, consider a transparency of the sub-areas as a measure of the concealed area.
- the processing module 34 is also set up to check whether the concealed area determined for at least one of the partial areas exceeds a permissible size.
- a warning module 35 is set up to output a warning signal W if this is the case.
- the processing module 34 can optionally check whether the concealed area determined for two or more adjacent partial areas exceeds a permissible size.
- the warning signal W can be output via an output 38 of the device 30, for example in order to trigger at least one measure for reducing the concealment.
- a display of picture elements in the area of the horizon or in the area of the vanishing point is preferably suppressed.
- the evaluation module 32, the subdivision module 33, the processing module 34 and the warning module 35 can be controlled by a control module 36. If necessary, settings of the evaluation module 32, the subdivision module 33, the processing module 34, the warning module 35 or the control module 36 can be changed via a user interface 39. If required, the data occurring in the device 30 can be stored in a memory 37 of the device 30, for example for later evaluation or for use by the components of the device 30.
- the evaluation module 32, the subdivision module 33, the processing module 34, the warning module 35 and the control module 36 can be implemented as dedicated hardware, for example as integrated circuits. Of course, they can also be partially or fully combined or implemented as software running on a suitable processor, such as a GPU or a CPU.
- the input 31 and the output 38 can be implemented as separate interfaces or as a combined interface.
- FIG. 6 shows a simplified schematic representation of a second embodiment of a device 40 for reducing occlusions by a virtual image of a head-up display of a means of transportation.
- the device 40 has a processor 42 and a memory 41 .
- the device 40 is a controller or an embedded system. Instructions are stored in the memory 41 which, when executed by the processor 42, cause the device 40 to carry out the steps according to one of the methods described.
- the instructions stored in the memory 41 thus embody a program which can be executed by the processor 42 and implements the method according to the invention.
- the Device 40 has an input 43 for receiving information. Data generated by the processor 42 is provided via an output 44 .
- the input 43 and the output 44 can be combined to form a bidirectional interface.
- Processor 42 may include one or more processing units, such as microprocessors, digital signal processors, or combinations thereof.
- the memories 37, 41 of the devices described can have both volatile and non-volatile memory areas and can include a wide variety of memory devices and storage media, for example hard disks, optical storage media or semiconductor memories.
