Definitions
- Camera arrangement for detecting a wheel condition of a vehicle window
- the invention relates to a camera arrangement for detecting a wheel condition of a vehicle window.
- a vehicle with this camera arrangement and a method for determining a state of the vehicle window are provided.
- Camera arrangements for detecting a vehicle environment through a vehicle window of a vehicle, in particular a motor vehicle are used in particular in driver assistance systems, for example as part of a night vision system or as a warning system.
- driver assistance systems for example as part of a night vision system or as a warning system.
- camera arrangements are designed so that they can detect in particular the space in the direction of travel in front of the motor vehicle.
- DE 10 2004 015 040 A1 shows such a camera arrangement for detecting a vehicle environment by means of a vehicle window which, in addition to a primary function such as night vision support and / or lane departure warning and / or traffic sign recognition and / or reversing aid, has a secondary function in the form of a rain sensor provides.
- the camera arrangement has a radiation source, wherein optical radiation emitted by the radiation source is firstly coupled into the window pane and then decoupled, wherein the decoupled part of this optical radiation can be detected by an image sensor of a camera of the camera arrangement.
- the radiation emitted by the radiation source becomes so coupled into the window that it is totally reflected in an untensioned state of the vehicle window in the interior of the vehicle window up to the place of Auskoppeins. Wetting of the pane by rainwater reduces the total reflected proportion of this coupled-in radiation. Based on the reduced in this way intensity by the
- Radiation source emitted radiation can be determined by means of the camera assembly, the degree of wetting of the vehicle window. So that the radiation source does not interfere with a detection of a vehicle environment performed with the same image sensor, the image sensor is subdivided into a first subarea for detecting a vehicle environment and a second subarea for detecting a radiation radiated from the radiation source, wherein an overlap of these regions by the use of Aperture is prevented.
- this camera arrangement for detecting a vehicle environment through a vehicle window is disclosed in DE 102 01 522 A1.
- this camera arrangement comprises a secondary function, such as the detection of a visual obstruction, for example by raindrops on the vehicle window.
- the camera arrangement has a camera that is focused on an outdoor area.
- the visual obstruction is determined by measuring the blurring of an image acquired by means of an image sensor of the camera. In situations in which the vehicle environment contains too few contrasts, for example at night, it is possible to switch on a windscreen for a short time. Visual impairments are then detectable from the scattering of the illumination light. If a visual obstruction is detected, suitable measures can be taken, such as switching on a windshield wiper system or switching on a window heater.
- measurements of the image sensor in the case of different illuminations with second optical radiation emitted by the radiation source are thus recorded and evaluated.
- a first measurement with the radiation source switched on, ie with illumination by the second radiation, and a second measurement with the second radiation switched off or reduced in intensity can be recorded and the image signals of the image radiation can be recorded.
- sensors are compared with each other.
- the first optical radiation of the vehicle surroundings is additionally recorded, so that the image signals receive information of both radiations.
- the disc state of a vehicle window is changed. If the vehicle window is illuminated by a radiation source with second optical radiation in a disc state changed in this way, this leads to a change in an image recorded with the image sensor, this image being less optical or not at all second with respect to an image Radiation was lit, contains additional information.
- a pane state of the pane for example the strength of wetting of the vehicle window by rainwater.
- the comparison of this image information can be done for example by an evaluation of the camera arrangement.
- the disc state thus determined can be used for the initiation of measures, such as the involvement of a windshield wiper system.
- both the first optical radiation and the second optical radiation can be detected jointly by means of at least one subarea of the image sensor.
- both the first optical radiation and the second optical radiation can be detected together with the entire image sensor. The entire image sensor can thus be exploited for the detection of a vehicle environment as well as for the determination of a disk state.
- the second optical radiation of the radiation source In order to ensure that the image information of the vehicle environment recorded with the image sensor is not disturbed by the second optical radiation of the radiation source, it is preferably not activated in every image acquisition cycle of the image sensor but, for example, only in every nth image acquisition cycle.
- the frequency, the duration and / or the brightness of the illumination of the vehicle window by the second optical radiation can in particular be adapted to the situation, for example as a function of the situation be chosen from the external light conditions.
- the radiation source can be activated more frequently than during the day to ensure a high image capture rate of a vehicle environment during the day.
- Part of the image sensor in the absence of second radiation and a second portion of the image sensor is exposed to second optical radiation.
- the radiation source can only be switched on when the exposure of the first subarea of the image sensor is completed.
- the second subregion of the image sensor would be exposed together with first optical radiation and second optical radiation.
- Such an image capture is particularly useful for such image sensors that allow a temporally offset exposure of pixels / pixels.

- the camera arrangement 16 comprises a radiation source 3 for
- the radiation source 3 has e.g. one or more LEDs and is arranged in or on the camera housing 1 1 such that at least a section A of the vehicle window 1 can be illuminated by the second optical radiation 7, but a direct illumination of the camera optics 12 and the image sensor 4 by the second optical Radiation 7 is prevented, for example, with a shield 13.
- the illuminable with the radiation source 3 section A of the vehicle window 1 is in the detection range of the camera lens 12, so that a portion of the second optical radiation 7 via an illumination of the cutout A of the vehicle window 1 indirectly through the Bi-sensor 4 can be detected.
- the vehicle window 1 is dirty, for example if there is a rain water drop 8 on the window surface 9 in the region of the cutout A, this contamination leads, in particular by scattering, reflection and / or refraction, to a changed beam path and / or an altered one

- the combination of the further control unit with the device carrying out the evaluation or evaluation corresponds to the evaluation unit 10 shown in FIGS. 1, 2.
- the radiation source 3 may be a first measurement with active radiation source 3, i. with illuminated section A, and a second measurement without illumination of the section A, in particular with the radiation source 3 switched off.
- the radiation source 3 is switched on for every n th image acquisition cycle, where n is a number> 1, preferably greater than 10, for the entire image acquisition cycle ie at least one frame is output.
- the radiation source 3 is deactivated.

For example, depending on the lighting conditions of the vehicle environment, the rate at which an image is recorded when the vehicle window 1 is illuminated by the second optical radiation 7 can be increased or decreased. Furthermore, several images can be recorded one after the other with the radiation source 3 activated. These measures are particularly advantageous in low light conditions, for example, at night, in which a lower frame rate of images that reproduce the vehicle environment without the interference of the second optical radiation 7, can be sought.

- the image information that is not affected by the second optical radiation 7 can be evaluated for detecting a vehicle environment.
- the other image information can be used to determine a slice state, for example as described above, by comparison with image information in which illumination of the vehicle window 1 is deactivated.
