[0008] Furthermore, the initial optical information of the target light source is obtained, including: Acquire an image of the environment in front of the vehicle; Identify red luminous areas in environmental images as target light sources; Extract the initial optical information of the target light source.

[0009] Furthermore, identifying red luminous areas in the environmental image as target light sources includes: The environmental image is subjected to color space conversion to separate the red light channel component, resulting in the red luminous region.

[0010] Furthermore, the target light source includes a first ray and a second ray, the first ray being used to illuminate the target light source and the second ray being used to provide ambient lighting.

[0026] With the development of intelligent connected vehicles, cars have solved most of the pain points people experience while driving. However, at night, the red taillights of vehicles ahead are extremely dazzling, causing visual fatigue, tearing, and other problems, thus affecting safe driving. To mitigate or eliminate this situation, we can utilize the principles of color complementarity and visual balance in optics, combining and complementing multiple light sources to reduce or eliminate the visual impact on the human eye.

[0027] Visit Figure 1 To address the aforementioned technical problems, in a first aspect, the present invention provides a method for preventing glare from light, comprising: Step S101: Obtain the initial optical information of the target light source; Step S102: Process the initial optical information based on the visual perception model to obtain the optical parameter set of the target light source. The optical parameter set includes optimized optical information of at least one ray. Step S103: Input the optical parameter set into the external light source module so that it emits the corresponding target light source.

[0028] The technical solution of this invention acquires the initial optical information of the target light source, enabling precise capture of key data such as the spectrum, intensity, and spatial distribution of the taillights of the preceding vehicle. This provides reliable input for subsequent compensation calculations, forming the data foundation for effective anti-glare. Processing this information based on a visual perception model and obtaining an optimized set of optical parameters transforms physical optical signals into visual response parameters that conform to the physiological and psychological characteristics of the human eye. This ensures that the generated compensation light is not only physically complementary but also precisely neutralized at the driver's visual perception level. Inputting the optical parameter set into an external light source module to emit the target light source directly achieves dynamic, real-time light compensation intervention. Its function is to actively adjust the light field distribution in front of the vehicle. By merging and canceling the compensation light projected in real time with the taillights of the preceding vehicle, it directly achieves the technical effect of reducing glare and improving visual comfort.

[0029] It can be explained that acquiring the initial optical information of the target light source refers to capturing real-time images of the environment in front of the vehicle using an image acquisition device (such as a high-definition camera) installed at the front of the vehicle. This image acquisition device has high dynamic range imaging capabilities, enabling it to clearly capture details of the scene ahead under different lighting conditions, especially exhibiting high sensitivity to luminous areas. After acquiring the environmental image, the system preprocesses the image, including noise reduction and contrast enhancement, to improve the accuracy of subsequent target light source identification. Subsequently, a deep learning-based image recognition algorithm is used to analyze the preprocessed environmental image and identify the red luminous area as the target light source.

[0030] It can be explained that processing initial optical information based on a visual perception model to obtain the optical parameter set of the target light source, including optimized optical information of at least one ray, means that the visual perception model is pre-trained using a large number of red light source samples containing different intensities and spectral characteristics, along with corresponding human eye comfort feedback data. This model integrates color complementarity theory and human eye visual characteristic curves, enabling it to simulate the human eye's visual perception process of different light combinations. When the initial optical information of the target light source (such as spectral characteristics, illuminance, and spatial location) is input, the model calculates the spectral parameters of the compensating ray that can form a visual balance with the red light of the target light source, such as its wavelength and intensity ratio, based on the principle of color complementarity. Simultaneously, combined with the spatial location information of the target light source, the model determines the projection direction and coverage area of ​​the compensating ray to ensure that the compensating ray can accurately superimpose with the target light source within the driver's field of vision. Furthermore, the model dynamically adjusts the intensity of the compensating ray according to changes in the illuminance of the target light source, ensuring that regardless of changes in the brightness of the taillights of the preceding vehicle, the overall brightness after fusion remains within a comfortable range for the human eye, avoiding excessive brightness or darkness that could cause new interference to the driver's vision.

[0031] To explain, inputting the optical parameter set into an external light source module to emit the corresponding target light source means that the vehicle is equipped with a light source module electrically connected to the processing module. This light source module can be composed of multiple sets of high-brightness LED beads and has independent spectral adjustment and power control units. When the processing module outputs the optical parameter set of the target light source (covering specific parameters such as spectral characteristics, light intensity, and spatial position), the drive circuit of the light source module will precisely control the working state of each LED bead according to these parameters. For example, it will adjust the luminous intensity ratio of different colored LEDs to generate compensating light of a specific spectrum, and project the light to the spatial position corresponding to the target light source (the taillights of the front vehicle) through the steering mechanism or multiple sets of directional emission units.

[0032] Visit Figure 2 In some embodiments, the optical information includes spectral features, the visual perception model includes a spectral feature mapping relationship, and step S102 includes: Step S201: Based on the spectral feature mapping relationship, map the spectral features of the target light source to the spectral features of the intended light source.

[0033] In this embodiment, by establishing a spectral feature mapping relationship, the precise conversion from the spectral features of the target light source to the spectral features of the intended light source can be achieved. This mapping relationship is constructed based on the theory of complementary colors and a large amount of experimental data. For example, when the dominant wavelength of the red light source is 650nm, the spectral feature mapping relationship can determine that the dominant wavelength of the intended light source is a warm yellow light of about 580nm. At the same time, the intensity ratio of the two is adjusted so that the fused light presents a soft orange-yellow tone in human perception, avoiding the glare of a single red light and preventing visual disharmony caused by the introduction of cool-toned light. This mapping relationship is not fixed but dynamically adjusted according to subtle changes in the spectrum of the target light source. For example, if the taillights of the vehicle in front have a small amount of orange light mixed into their spectrum due to aging, the model will automatically correct the spectral parameters of the intended light source to ensure that the best visual compensation effect is always maintained.

[0034] Specifically, this mapping relationship can be represented as a preset spectral transformation matrix or function model. The elements in the matrix or the parameters of the function are obtained by testing various typical red light source samples and optimizing them in conjunction with human eye comfort evaluation data. When the spectral characteristic data of the target light source (such as the energy distribution of light at each wavelength) is input, the system will call this mapping relationship and, through matrix operations or function calculations, directly output the spectral parameters such as the energy ratio of light at each wavelength required by the target light source. This provides the core spectral basis for the subsequent light source module to generate compensation light, ensuring that the target light source can form an effective complementary balance with the target light source at the spectral level.

[0035] Visit Figure 3 In some embodiments, the optical information includes light intensity, the visual perception model includes a light intensity mapping relationship, and step S102 includes: Step S301: Map the light intensity of the target light source to the light intensity of the intended light source based on the light intensity mapping relationship.

[0036] In this embodiment, by establishing a light intensity mapping relationship, the light intensity of the target light source can be dynamically adjusted according to the actual light intensity of the target light source, so as to achieve a precise match and balance between the two in terms of intensity. This mapping relationship is not a simple linear correspondence, but comprehensively considers the nonlinear characteristics of human eye perception of light of different intensities and the safety requirements in driving scenarios.

[0037] Specifically, the light intensity mapping relationship can be represented by a nonlinear function. The input to this function is the real-time light intensity value of the target light source, and the output is the optimal light intensity value for the target light source. For example, when the target light source has a low light intensity (such as in a well-lit urban street where the taillights of the car in front are relatively less glaring, with an illuminance value of 50-100 lux), the function may output a low compensation light intensity, requiring only slight neutralization to avoid excessive compensation light affecting the visibility of the taillights of the car in front. Conversely, when the target light source has a high light intensity (such as on a highway with strong taillights at a distance, with an illuminance value exceeding 200 lux), the function will output a significantly enhanced compensation light intensity to ensure sufficient light energy to counteract the glare caused by the strong light. Simultaneously, the function also sets an upper limit threshold for the compensation intensity to prevent the target light source itself from becoming a new source of glare. For example, regardless of the intensity of the target light source, its intensity will not exceed the human eye comfort threshold (e.g., a preset value of 150 lux). In addition, the light intensity mapping relationship also takes into account the overall level of ambient light. In a dark environment, even if the absolute intensity of the target light source is not high, its relative contrast may be high. In this case, the mapping relationship will appropriately increase the compensation intensity. Conversely, in the case of strong ambient light such as streetlights, the compensation intensity will be appropriately reduced to maintain the balance of the overall visual environment and ensure that the driver can see the road conditions ahead clearly without being overstimulated by a specific light source.

[0038] Visit Figure 4 In some embodiments, the optical information includes spatial location, the visual perception model includes spatial location mapping relationships, and step S102 includes: Step S401: Based on the spatial position mapping relationship, map the spatial position of the target light source to the spatial position of the intended light source.

[0039] In this embodiment, by establishing a spatial position mapping relationship, it is possible to ensure that the projection position of the target light source precisely corresponds to the actual spatial position of the target light source, thereby achieving accurate superposition and fusion of the two in the driver's field of vision. This mapping relationship is constructed based on the transformation between the vehicle coordinate system and the image coordinate system, as well as the physical installation parameters of the light source module. Its core lies in converting the position information of the target light source in three-dimensional space into specific control parameters of the light source module, such as steering angle and projection distance.

[0040] Specifically, once the system acquires the spatial position information of the target light source (such as its distance in front of the vehicle, horizontal offset angle, and vertical height), the spatial position mapping relationship calculates the horizontal steering angle and vertical pitch angle that the light source module needs to adjust based on its installation position on the vehicle (e.g., on the front bumper, below the rearview mirror, or inside the headlight assembly) and its adjustable range (e.g., horizontal rotation angle range, vertical pitch angle range). This ensures that the compensating light can be accurately projected onto the spatial area where the target light source is located. For example, if the target light source is located 30 meters directly in front of the vehicle, offset horizontally by 5 degrees to the right, the spatial position mapping relationship will combine the installation height and initial angle of the light source module to calculate that the light source module needs to rotate 5 degrees to the right and adjust the pitch angle to adapt to the projection requirements at a distance of 30 meters, so that the compensating light and the target light source completely overlap in the driver's field of vision. In addition, the mapping relationship also takes into account the vehicle's own motion state. For example, when the vehicle turns, the system will update the spatial position of the target light source in real time according to the steering angle and vehicle speed, and dynamically adjust the projection direction of the light source module through the spatial position mapping relationship to ensure that the compensation light always accurately tracks the target light source during the vehicle's movement, avoiding compensation misalignment caused by changes in vehicle posture, thereby continuously and effectively playing the anti-glare role.

[0041] Visit Figure 5 In some embodiments, step S101 includes: Step S501: Acquire an image of the environment in front of the vehicle; Step S502: Identify the red luminous area in the environmental image as the target light source; Step S503: Extract the initial optical information of the target light source.

[0042] In this embodiment, an image of the environment in front of the vehicle is first acquired to provide the initial data foundation for subsequent identification and extraction of the target light source's initial optical information. The acquired environmental image is processed to identify the red emitting region as the target light source. This process may involve image preprocessing, including noise reduction and contrast enhancement, to improve the accuracy of subsequent target light source identification. Then, the preprocessed environmental image is analyzed, and by comprehensively judging the color, brightness, and shape features of pixels in the image, the red emitting region is accurately located and identified, thereby determining the position of the target light source. Finally, after identifying the red emitting region, the initial optical information of the target light source is extracted from this region. This initial optical information provides key input data for subsequent processing based on a visual perception model to obtain the optical parameter set of the target light source.

[0043] Visit Figure 6 In some embodiments, step S502 includes: Step S601: Perform color space conversion on the environmental image to separate the red light channel component and obtain the red luminous area.

[0044] In this embodiment, the environmental image is converted from the common RGB color space to the HSV (Hue, Saturation, Value) color space or the YCrCb color space. In the HSV color space, red has a specific hue (H) range. By setting a reasonable H value range, the red component in the image can be effectively separated. Simultaneously, by combining saturation (S) and value (V) threshold conditions, non-target areas with dull colors or insufficient brightness are excluded. In the YCrCb color space, the Cr component represents the difference between the red channel and the value component. By setting a lower threshold for the Cr component and combining it with an upper threshold for the Cb component (blue channel difference), the red luminous area can be further extracted more precisely. Through this color space conversion and channel separation method, the red luminous area can be quickly and accurately located from complex environmental images, laying the foundation for subsequent extraction of the optical information of the target light source. This ensures that only genuine red luminous targets (such as the taillights of a vehicle) are identified as the target light source, reducing background interference and misidentification.

[0045] Specifically, the acquired RGB format environmental image is converted to HSV format. For example, the hue (H) is set to a range of 0° to 10° and 350° to 360°, which basically cover the main hue range of red light. Next, a threshold for saturation (S) is set, such as S greater than 30%, to exclude areas that are too dark, close to white or gray, ensuring that only red with a certain degree of vibrancy is extracted. The threshold for brightness (V) can be set to greater than 50% to filter out luminous areas with sufficient brightness, avoiding misidentification of red objects in shadows as light sources. Through threshold filtering in these three dimensions, the system can initially segment possible red luminous areas from the environmental image. Subsequently, morphological processing, such as erosion and dilation operations, is performed on these areas to remove small noise points and connect areas of the same light source that may be slightly occluded or separated, ultimately obtaining red luminous areas with clear outlines and accurate boundaries, thereby reliably determining the location of the target light source.

[0046] In some embodiments, the target light source includes a first light ray and a second light ray, the first light ray being used to illuminate the target light source and the second light ray being used to provide ambient lighting.

[0047] In this embodiment, by designing the target light source to include a first ray and a second ray, the anti-glare function can be achieved while also meeting the basic lighting needs of the driving environment, thus improving overall driving safety. The first ray, as the core anti-glare compensation ray, precisely illuminates and acts on the target light source (such as the taillights of a vehicle ahead). By matching and fusing with the target light source's spectrum, intensity, and spatial position, it neutralizes the glare effect. The first ray adjusts its spectral characteristics and light intensity according to the optical parameter set output by the processing module, and ensures accurate superposition with the target light source in the driver's field of vision through a directional projection mechanism, effectively counteracting the glare effect of the target light source. The second ray provides ambient lighting. This means that the second ray does not directly act on a specific target light source, but rather illuminates the road ahead, the surrounding environment, or a specific area to meet the driver's basic observation needs regarding road conditions. For example, at night or in low-light conditions, when the vehicle's anti-glare function is activated, the second ray can provide moderate and uniform basic lighting to help the driver identify non-light source targets such as road markings, obstacles, and pedestrians. The optical parameters (such as spectrum and intensity) of the second light source can be set independently or optimized in conjunction with the first light source. Its spectrum can be selected to be white light or warm white light close to natural light to provide good visual recognition. The light intensity can be automatically adjusted according to the overall level of ambient light to avoid being too bright and affecting the observation of other road users, or too dark and causing the driver to have insufficient perception of non-light source targets.

[0048] Furthermore, the light source module can generate and control the first and second light rays separately through different optical channels or independent emission units. For example, a portion of the LED bead group in the light source module is dedicated to generating the first light ray, equipped with a high-precision directional projection and spectral adjustment unit; another portion of the LED bead group is responsible for generating the second light ray, which can use a wide-angle projection method to provide a larger area of ​​ambient lighting. The processing module dynamically coordinates the working models of the first and second light rays according to the vehicle's driving status, ambient lighting conditions, and the target light source, ensuring effective anti-glare for the target light source while providing the driver with a clear and comfortable overall visual environment.

[0049] In one embodiment, the first light source is warm yellow light, and the second light source is off-white. This configuration ensures that the wavelength range of the warm yellow light (e.g., 550-600nm) is spectrally adjacent and compatible with the target light source (e.g., 620-750nm for red taillights). This allows for the softening of strong red light through a specific spectral combination, avoiding color distortion that might occur with complementary colors, and reducing the interference of sudden color changes on the driver's visual adaptation. The off-white second light source, due to its spectral composition close to natural light (containing a wide range of visible light wavelengths and relatively uniform energy distribution), provides high-definition ambient lighting, making the driver's color perception of non-light source targets such as road details, traffic signs, pedestrians, and obstacles closer to daytime conditions, reducing nighttime visual fatigue. When all three are combined, a natural transition visual effect is created in the driver's field of vision, avoiding a visual discontinuity caused by excessive color differences between the first and second light sources. The warm yellow first light focuses on the target light source area, providing targeted spectral and intensity compensation for the red taillights, making them appear as a soft, warm-toned light spot to the driver's eyes. This is neither dazzling nor insufficient to clearly identify the position of the vehicle ahead. Meanwhile, the off-white second light evenly covers the road in front of the vehicle, providing illumination close to natural daylight. This helps the driver accurately judge the road outline, markings, and obstacles in the surrounding environment. The two work together to eliminate the glare problem of the red taillights while ensuring the brightness and clarity of the overall driving vision, significantly improving the safety and comfort of nighttime driving.

[0050] The second invention also proposes a light anti-glare system for implementing the above-mentioned light anti-glare method, comprising: The acquisition module is used to obtain the initial optical information of the target light source; The processing module is used to process the initial optical information based on the visual perception model to obtain the optical parameter set of the target light source, which includes optimized optical information of at least one ray. The execution module is used to input the optical parameter set into an external light source module so that it emits the corresponding target light source.

[0051] It is understandable that this anti-glare lighting system has all the beneficial effects of the aforementioned anti-glare lighting methods, which will not be elaborated upon here.

[0052] Specifically, in one embodiment, the acquisition module includes a camera from the AVM (Around View Monitor) which, in some embodiments, can also assist in providing images of the environment in front of the vehicle, providing data support for the identification of target light sources. The processing module includes a cockpit domain controller, responsible for receiving initial optical information of the target light source from the acquisition module (such as an image acquisition device installed at the front of the vehicle, like a camera), and performing calculations based on a preset visual perception model to generate an optical parameter set for the target light source. The execution module includes the vehicle's CAN / LIN bus, which handles data transmission between modules, ensuring that information acquired by the acquisition module is promptly transmitted to the processing module, and that control commands generated by the processing module are accurately sent to the execution module and the light source module. The light source module includes a headlight device, which can use multiple sets of high-brightness LED beads as light-emitting units. These LED beads have independent drive control circuits, capable of precisely adjusting the luminous intensity and spectral characteristics according to the optical parameter set output by the processing module.

[0053] In some embodiments, the anti-glare lighting system further includes: The display module is used to visualize the working data of the acquisition module, processing module, and execution module.

[0054] In this embodiment, by setting up a display module, the working status and key data of each core module of the anti-glare lighting system can be presented to the driver or system maintenance personnel in an intuitive way, facilitating real-time monitoring of system operation and troubleshooting. The display module can be integrated into the vehicle's dashboard, central control display screen, or dedicated in-vehicle infotainment system. Through graphical interfaces, text information, or data charts, it dynamically displays key frames of environmental images acquired by the acquisition module, identification marks of the target light source (such as square markings of red luminous areas), and initial optical information (such as the intensity value and spatial coordinates of the target light source). At the same time, it can also display the calculation results of the processing module, including the output parameters of the visual perception model, the optical parameter set of the target light source (such as the intensity, spectral parameters, and projection angle of the first and second rays), and the instruction execution status of the execution module, such as whether the light source module has accurately emitted the target light source according to the optical parameter set, and the current working model of the light source module.

[0055] Specifically, the display module includes a central control display screen, which is used to show the driver the working status of the anti-glare system, the target light source recognition results, compensation light parameters, and other information, so that the driver can intuitively understand the system's operation and enhance the transparency and controllability of information during driving.

[0056] Thirdly, the present invention provides a vehicle including the aforementioned anti-glare lighting system.

[0057] It is understandable that the vehicle has all the beneficial effects of the aforementioned anti-glare lighting system, which will not be elaborated upon here.

[0058] Understandably, the vehicle can be any type of motor vehicle, such as a sedan, SUV, truck, or bus. When a vehicle is equipped with this anti-glare lighting system, it can effectively identify and process target light sources on the road ahead, such as the taillights of the vehicle in front and oncoming headlights, when driving at night or in low light conditions. By dynamically adjusting the target light source emitted by its own light source module, it achieves an anti-glare effect, thereby providing the driver with a clearer, more comfortable, and safer driving vision and reducing the driving risks caused by strong glare.
