Definitions
- the invention relates to a method and a device for guiding a vehicle, in which a driver controls the vehicle via his visual perception.
- the invention is therefore based on the object to provide a method and a device for guiding a vehicle, in which (s) a risk of dazzling the driver is significantly reduced.
- This object is achieved according to the invention in that the scene is detected in front of the driver of a video camera and displayed on a display.
- rays are filtered out in a frequency range in which blinding agents emit rays.
- video cameras and displays are preferably used which operate in the red to infrared range. In doing so, the usual wavelengths of laser pointers are blocked.
- preferably green and / or blue light is filtered out.
- the video cameras are set so that only objects at a defined distance from the vehicle are displayed on the display.
- Such an active system can be advantageously used in aircraft, for example, to display the touchdown point of the runway.
- An apparatus for carrying out a method according to the invention comprises a video camera for detecting the scene in front of the vehicle driver, a frequency filter which filters out beams emitted by glare means, and a display for displaying an image generated from filtered data.
- the device preferably contains at least one short wave infrared (SWIR) camera.
- SWIR short wave infrared
- multiple video cameras with overlapping fields of view are used to make the device redundant.
- Multi-color cameras are used to advantage if there is a risk of glare lasers whose frequency is in the spectral range of the camera. These also improve the redundancy, since images can be created from signals of different frequencies. If a vehicle is equipped with a device according to the invention, then the display is arranged in the field of vision of the vehicle driver. If a co-driver supports the vehicle guidance, it is advantageous to provide separate screens for the driver as well as for the co-pilot and to connect the screens redundantly.
- a land vehicle systems with video cameras and displays are used, which have their own autonomous and independent from the vehicle power supply system, for example, their own batteries.
- the vision system is preferably supplied redundantly by two energy supply systems which are not independent of the vehicle.
- FIG. 1 schematically shows a device for a vehicle
- Figure 2 schematically shows a redundant power supply for the
- the device contains a camera module 1, which in the example contains three video cameras 2, 3, 4.
- Video cameras are understood to be cameras which record electromagnetic radiation in the visible and non-visible frequency range and convert it continuously into electrical signals.
- video cameras 2, 3, 4 are used which operate in the red to infrared frequency range.
- the Cameras 2-4 are aligned so that their fields of view 5, 6, 7 partially overlap. Each area of the scene centrally in front of the driver is thus detected by at least two video cameras 2-4.
- the imaging system integrated into the camera module 1 includes a frequency filter that filters out beams received in frequency ranges, such as those typically provided by blending agents. In the case of laser pointers as a glare agent, it is preferred to filter out rays that have been received as green and blue light.
- the filtering out of the frequencies of the blinding agent can, for example, take place in such a way that first the over-glare on the affected spectral range is recognized in the image. Subsequently, the corresponding channel is attenuated or switched off.
- the filtering out and blocking of the unwanted wavelengths takes place in-camera through the spectral sensitivity ranges of the detectors used. Furthermore, an infrared optics is used in the cameras, which has a damping effect with respect to the wavelength ranges to be blanked out.
- From the filtered data images are generated by an imaging system, which are displayed on two screens 8, 9 as displays.
- a screen 8 is arranged in the vehicle in the field of vision of the driver, in the example of a pilot.
- the second screen 9 is arranged in the field of vision of the co-pilot.
- images are displayed on the two screens 8, 9. It is possible that identical images are displayed on the two screens 8, 9.
- the two screens 8, 9 represent different views, and in the event of failure of one screen, the remaining screen always displays the picture that is more critical for flight safety.
- Different views on the two Screens 8, 9 can also increase landing security, particularly in the case of aircraft: one pilot lands in visual flight and the other pilot is in standby in the event of a glare attack on the active vision system.
- the screens 8, 9 are redundantly connected to each other so that one always remains functional.
- the device according to the invention is adapted to the specific application.
- the present example is intended for use in an aircraft controlled by a pilot and a co-pilot.
- SWIR Short Wave Infrared
- the video cameras 2-4 can be set so that only objects at a defined distance from the vehicle, here an aircraft, are displayed on the display.
- Such an active system can be used as a so-called "Time of Flighf" system to indicate the landing point of the aircraft on the runway.
- a multicolor camera is used.
- the multicolor camera is capable of producing images of rays with frequencies outside the spectral range of the dazzling laser.
- the power supply is always redundant for safety reasons, for example, by two engines and subsequent separately held energy strands.
- the power supply systems can be switched so that when a system fails, the second screen is still powered.
- the scheme of a redundant power supply for an aircraft is shown in FIG. If the device is provided for guiding a land vehicle, it is preferably provided with its own autonomous and vehicle-independent power supply system.
- the preferably battery-powered power supply system makes it possible to power video cameras and displays, even if the power supply of the vehicle or the connection to the supply system of the vehicle is disturbed.
