Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a screen brightness adjustment method, device, storage medium and electronic device. Background Art

[0002] With the development of smart cars, especially the popularity of new energy vehicles, the vehicle's interactive system has developed into a multi-screen display. The number of display screens will gradually increase from the current two to three, four or even more. In order to improve the display effect, the vehicle adjusts the screen brightness to a higher level. When the vehicle is driving in a strong light environment, such as a tunnel, tunnel exit, rainy or snowy day, the screen display in the driver's field of view will be too bright due to the strong light, causing visual fatigue of the driver and affecting driving safety.

[0003] At present, cameras are used in automobile intelligent interaction systems to monitor the driver's status. The cameras commonly used are driver monitoring cameras, rear-view cameras and surround-view cameras. Driver monitoring cameras are used to monitor the driver's status. Driver monitoring cameras mainly use image processing technology to analyze the feature points in the images collected by the camera to determine the driver's facial features, thereby determining the driver's status, such as whether the driver has closed his eyes, yawned, slept, or is tired.

[0004] However, current driver monitoring cameras are only used to determine the state of the driver, and are not used to adjust the screen brightness. Therefore, current driver monitoring cameras cannot adjust the screen brightness according to the state of the driver.

[0038] The embodiment of the present application provides a method for adjusting screen brightness. The screen brightness adjustment method can be used to provide a screen brightness adjustment function for preset application scenarios. The above-mentioned preset application scenarios may include the following scenarios in the vehicle field: commuting automatic driving scenarios, artificial intelligence (AI) driving scenarios for family cars, automatic parking assistance (APA) scenarios (such as memory parking for owned parking spaces in garages, smart parking for designated parking spaces in parking lots, etc.), and intelligent navigation assistance (Navigation Guided Pilot, NGP) scenarios in urban areas or high-speed areas. In addition, the above-mentioned preset application scenarios may also include, but are not limited to: screen brightness adjustment scenarios for smart driving trucks or unmanned trucks in the field of logistics and transportation, and screen brightness adjustment scenarios for self-driving agricultural vehicles in the field of agricultural machinery.

[0039] When the above-mentioned preset application scenario is a scenario in a field other than the vehicle field, those skilled in the art should be able to understand that the vehicle in the above-mentioned screen brightness adjustment method can be replaced with other objects (such as agricultural machinery, etc.), and accordingly, the screen brightness adjustment device can be replaced with a screen brightness adjustment device related to other objects. On this basis, the specific implementation of the above-mentioned screen brightness adjustment method is exemplified in the embodiment of the present application, taking the field of vehicle technology as an example.

[0040] Figure 1is a flow chart of a method for adjusting screen brightness according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0041] Step S10, obtaining a facial orientation of a driver in the vehicle, a first position of a first camera, and a second position of a second camera, wherein the facial orientation is used to reflect the eye gaze position of the driver, and the first camera and the second camera respectively photograph the driver from different angles;

[0042] In the embodiment of the present invention, the facial orientation can be understood as the direction of the driver's head and sight line relative to the position of the vehicle's internal screen or other in-vehicle equipment. For example, the driver's sight line direction can be estimated by analyzing the position of the driver's eyes and head to determine whether the driver is looking at a certain screen, which is not limited here.

[0043] The first camera can be understood as a camera installed in the car and used to capture the driver's facial information and the interior environment of the car. Figure 2 is a schematic diagram of a sensor according to a screen brightness adjustment method according to an embodiment of the present invention. Figure 2 As shown, exemplarily, the first camera may be a driver monitoring system (DMS) camera, which is used to monitor the driver's status, such as fatigue, distraction or sleep, to remind the driver to stay alert and ensure driving safety, which is not limited here.

[0044] The first position can be understood as the specific installation position of the first camera inside the vehicle. For example, the first camera is usually installed at the front of the vehicle, and its specific position may be near the rearview mirror, above the dashboard, or in the A-pillar area. Such a position is conducive to directly capturing the front image of the driver's face, especially when the driver is facing forward, and can accurately monitor the driver's attention state and facial orientation, which is not limited here.

[0045] The second camera can be understood as a camera installed in the car and different from the first camera, which is used to capture the driver's facial information and the environment inside the car. Figure 2 is a schematic diagram of a sensor according to a screen brightness adjustment method according to an embodiment of the present invention. Figure 2 As shown, exemplarily, the second camera can be an occupant monitoring system (OMS) camera, which is used to monitor the status of passengers in the vehicle, such as whether they are wearing seat belts, whether they are in the correct seats, etc., to ensure the safety and comfort of passengers, which is not limited here.

[0046] The second position can be understood as the specific installation position of the second camera inside the vehicle. For example, the installation position of the second camera is more flexible, but it is usually in an area in the car that can cover a wider field of view, such as the roof, the top of the door, or above the center console. The second camera not only monitors the driver, but may also monitor occupants in other positions in the car, so its position needs to be able to observe the driver and possible other passengers. In this application, the position of the second camera helps to more comprehensively determine the driver's facial orientation in different directions, which is not limited here.

[0047] Obtaining the facial orientation of the driver in the vehicle, the first position of the first camera, and the second position of the second camera can be understood as utilizing the DMS camera installed at the first position and the OMS camera installed at the second position to capture the driver's facial image and posture information in real time, and determining the driver's current line of sight direction and facial orientation by analyzing the driver's facial image and posture information, which is not limited here.

[0048] In the embodiment of the present invention, by determining the specific installation positions of the cameras in the vehicle and using these cameras to capture and analyze the driver's facial images, the driver's attention focus and facial orientation are monitored and understood in real time, and corresponding intelligent adjustment measures are taken.

[0049] Step S11, determining a first relative angle based on the facial orientation and the first position, and determining a second relative angle based on the facial orientation and the second position;

[0050] In the embodiment of the present invention, the first relative angle may be exemplarily understood as the relative angle between the driver's facial orientation and the first camera (DMS camera), which is not limited herein.

[0051] The second relative angle can be understood as the relative angle between the driver's facial orientation and the second camera (OMS camera), which is not limited here.

[0052] Determining the first relative angle based on facial orientation and the first position can be understood as, exemplarily, utilizing the specific installation position of the DMS camera (i.e., the first position) and the captured driver's facial orientation information to perform data analysis and processing to calculate the relative angle (i.e., the first relative angle) between the driver's head and the DMS camera, which is not limited here.

[0053] Determining the second relative angle based on facial orientation and the second position can be understood as, for example, using the driver's facial orientation information and the specific installation position (i.e., the second position) of the second camera (OMS camera) to calculate the relative angle (i.e., the second relative angle) between the driver's head and the OMS camera, which is not limited here.

[0054] In an embodiment of the present invention, a first relative angle is determined based on facial orientation and a first position, and a second relative angle is determined based on facial orientation and a second position. By using a technology for determining relative angles based on facial orientation and camera position, not only driving safety is improved but also driving experience is optimized.

[0055] Step S12, determining a target screen that the driver is looking at from a plurality of vehicle-mounted screens built into the vehicle according to the first relative angle and the second relative angle;

[0056] In the embodiment of the present invention, the vehicle-mounted screen can be exemplarily understood as various display screens installed inside the vehicle for displaying information, operating vehicle functions and providing entertainment, which is not limited here.

[0057] The target screen that the driver is looking at is determined from multiple on-board screens built into the vehicle based on the first relative angle and the second relative angle. This can be understood as, for example, determining the target screen that the driver is looking at from display screens installed inside the vehicle based on the relative angle between the driver's facial orientation and the first camera (DMS camera) and the relative angle between the driver's facial orientation and the second camera (OMS camera). This is not limited here.

[0058] In an embodiment of the present invention, determining the target screen that the driver is looking at from multiple vehicle-mounted screens built into the vehicle based on the first relative angle and the second relative angle helps the system intelligently adjust the screen brightness and functions to avoid high-brightness screens distracting the driver, especially at night or in low-light environments, thereby reducing driving risks.

[0059] Step S13, performing brightness grading control on the target screen and screens other than the target screen.

[0060] In the embodiment of the present invention, brightness grading control can be understood as intelligently adjusting the brightness of different screens in the car according to the driver's attention distribution.

[0061] The target screen and screens other than the target screen are controlled in brightness levels. This can be understood as controlling the different brightness levels of the vehicle screen that the driver is currently looking at or needs to interact with and other display screens in the vehicle, which is not limited here.

[0062] In the embodiment of the present invention, brightness grading control is performed on the target screen and screens other than the target screen, which is an intelligent screen brightness adjustment technology based on driver attention distribution, aiming to provide a safer and more comfortable driving environment and a more efficient and personalized information display service.

[0063] By determining the specific installation position of the in-vehicle camera and using these cameras to capture and analyze the driver's facial image, the driver's attention focus and facial orientation can be monitored and understood in real time, and corresponding intelligent adjustment measures can be taken. The first relative angle is determined based on the facial orientation and the first position, and the second relative angle is determined based on the facial orientation and the second position. The technology of determining the relative angle based on the facial orientation and the camera position not only improves driving safety but also optimizes the driving experience. Determining the target screen that the driver is looking at from the multiple on-board screens built into the vehicle based on the first relative angle and the second relative angle helps the system to intelligently adjust the screen brightness and function, avoid high-brightness screens distracting the driver's attention, especially at night or in low-light environments, and reduce driving risks. Brightness grading control of the target screen and screens other than the target screen is an intelligent screen brightness adjustment technology based on the driver's attention distribution, which aims to provide a safer and more comfortable driving environment and more efficient and personalized information display services.

[0064] Through the above steps, the facial orientation of the driver in the vehicle, the first position of the first camera and the second position of the second camera are obtained, wherein the facial orientation is used to reflect the gaze position of the driver's eyes, and the first camera and the second camera respectively shoot the driver from different angles; the first relative angle is determined based on the facial orientation and the first position, and the second relative angle is determined based on the facial orientation and the second position; the target screen that the driver is looking at is determined from multiple vehicle-mounted screens built into the vehicle according to the first relative angle and the second relative angle; the target screen and screens other than the target screen are controlled in a graded manner, that is, the image recognition module that uses the image processing technology to analyze the rotation angle and the tilt degree of the driver's head to determine the screen being looked at by the first camera and the second camera that collect the driver's facial orientation data in real time, and the screen brightness adjustment module that implements the partition brightness adjustment strategy according to the judgment result, adjusts the brightness of the screen that the driver is looking at to the first target brightness, and maintains the lower second target brightness of other screens, thereby achieving the purpose of intelligently adjusting the display brightness of the vehicle screen in different partitions, thereby achieving the technical effect of improving the driving experience, and further solving the technical problem of the high brightness of the vehicle screen causing visual interference to the driver in the related art.

[0065] Optionally, in step S12, determining the target screen that the driver is looking at from a plurality of vehicle-mounted screens built into the vehicle according to the first relative angle and the second relative angle may include the following execution steps:

[0066] In response to the first relative angle being a positive angle and the second relative angle being a negative angle, it is determined that the target screen is an instrument screen.

[0067] In the embodiment of the present invention, the positive angle can be understood as, exemplarily, when the driver's head or sight is deflected to the right relative to a camera, this angle difference is usually defined as a positive angle, which is not limited here.

[0068] A negative angle can be understood as, for example, when the driver's head or sight is turned to the left relative to the camera, the angle difference is defined as a negative angle, which is not limited here.

[0069] The first relative angle being a positive angle can be understood as, for example, referring to the angle at which the driver is facing the DMS camera, which is biased to the right, that is, the driver's line of sight is deflected to the right relative to the position of the DMS camera, which is not limited here.

[0070] The second relative angle being a negative angle can be understood as, for example, referring to the angle at which the driver is facing the OMS camera being biased to the left, that is, the driver's line of sight is deflected to the left relative to the position of the OMS camera, which is not limited here.

[0071] In response to the first relative angle being a positive angle and the second relative angle being a negative angle, determining that the target screen is the instrument screen can be understood as, for example, when the driver's angle toward the DMS camera is biased to the right and the driver's angle toward the OMS camera is biased to the left, the system can reasonably infer that the driver's current attention is focused on the instrument screen, which is not limited here.

[0072] In the embodiment of the present invention, by determining that the driver is looking toward the DMS camera at a right angle and the driver is looking toward the OMS camera at a left angle, the system can reasonably infer that the driver's current attention is focused on the instrument screen, thereby reducing the possibility of misjudgment and making the attention monitoring function more reliable.

[0073] Optionally, in step S12, determining the target screen that the driver is looking at from a plurality of vehicle-mounted screens built into the vehicle according to the first relative angle and the second relative angle may include the following execution steps:

[0074] In response to the second relative angle being a positive angle and the second relative angle being less than the first angle threshold, it is determined that the target screen is the central control screen, wherein the first angle threshold is the difference between the first angle and a preset calibration value.

[0075] In the embodiment of the present invention, the first angle threshold may be understood as a key parameter for determining whether the driver is looking at the central control screen. Figure 3 is a schematic diagram of the implementation principle of a screen brightness adjustment method according to an embodiment of the present invention. Figure 3 As shown, the first angle threshold can be expressed as f°-calibration value, which is not limited here.

[0076] In response to the second relative angle being a positive angle, it can be understood exemplarily that, based on the relative angle between the driver and the OMS camera, it is determined that the driver's head or line of sight is deflected to the right relative to the camera, which is not limited here.

[0077] The second relative angle being less than the first angle threshold can be understood, for example, as the relative angle between the driver and the OMS camera being less than the difference between the first angle and a preset calibration value, which is not limited here.

[0078] In response to the second relative angle being a positive angle and the second relative angle being less than the first angle threshold, the target screen is determined to be the central control screen. By way of example, it can be understood that based on the relative angle between the driver and the OMS camera, it is determined that the driver's head or line of sight is deflected to the right relative to the camera, and the relative angle between the driver and the OMS camera is less than the difference between the first angle and the preset calibration value, indicating that although the driver's head or line of sight is deflected, it is still focusing on the direction of the central control screen, which is not limited here.

[0079] In the embodiment of the present invention, by judging the relative angle between the driver and the OMS camera, it is determined that the driver's head or sight is deflected to the right relative to the camera, and the relative angle between the driver and the OMS camera is less than the difference between the first angle and the preset calibration value. It can be reasonably inferred that the driver is looking at the central control screen, and the screen brightness is adjusted according to this judgment, which can not only improve the safety during driving, but also enhance the user experience and achieve energy saving and environmental protection.

[0080] Optionally, in step S12, determining the target screen that the driver is looking at from a plurality of vehicle-mounted screens built into the vehicle according to the first relative angle and the second relative angle may include the following execution steps:

[0081] In response to the second relative angle being a positive angle and the second relative angle being greater than or equal to the first angle threshold and less than or equal to the second angle threshold, it is determined that the target screen is the co-pilot screen, wherein the second angle threshold is the sum of the first angle and a preset calibration value.

[0082] In the embodiment of the present invention, the second angle threshold may be understood as a key parameter in the vehicle's internal intelligent system for accurately identifying the relationship between the driver's facial orientation and the passenger screen. Figure 3 is a schematic diagram of the implementation principle of a screen brightness adjustment method according to an embodiment of the present invention. Figure 3 As shown, the second angle threshold can be expressed as f°+calibrated value, which is not limited here.

[0083] The second relative angle is greater than or equal to the first angle threshold and less than or equal to the second angle threshold, which can be understood as the relative angle between the driver and the OMS camera is greater than or equal to the difference between the first angle and the preset calibration value and less than or equal to the sum of the first angle and the preset calibration value, which is not limited here.

[0084] In response to the second relative angle being a positive angle and the second relative angle being greater than or equal to the first angle threshold and less than or equal to the second angle threshold, the target screen is determined to be the co-pilot screen. By way of example, it can be understood that based on the relative angle between the driver and the OMS camera, it is determined that the driver's head or line of sight is deflected to the right relative to the camera, and the relative angle between the driver and the OMS camera is greater than or equal to the difference between the first angle and the preset calibration value and less than or equal to the sum of the first angle and the preset calibration value. In other words, it can be determined that the driver is looking at the co-pilot screen, which is not restricted here.

[0085] In the embodiment of the present invention, by judging the relative angle between the driver and the OMS camera, it is determined that the driver's head or line of sight is deflected to the right relative to the camera, and the relative angle between the driver and the OMS camera is greater than or equal to the difference between the first angle and the preset calibration value and less than or equal to the sum of the first angle and the preset calibration value, thereby inferring that the screen the driver is looking at is the co-pilot screen, and then intelligent screen brightness adjustment is implemented for the co-pilot screen and other display screens, which not only improves driving safety but also optimizes the driving experience.

[0086] Optionally, the screen brightness adjustment method further includes:

[0087] In response to the second relative angle being greater than the second angle threshold, exiting the screen brightness control.

[0088] In the embodiment of the present invention, in response to the second relative angle being greater than the second angle threshold, it can be understood exemplarily that the relative angle between the driver and the OMS camera is greater than the sum of the first angle and the preset calibration value, which is not limited here.

[0089] In response to the second relative angle being greater than the second angle threshold, the screen brightness control is exited. By way of example, it can be understood that when the relative angle between the driver and the OMS camera is greater than the sum of the first angle and the preset calibration value, the system will automatically exit the intelligent control mode of the co-pilot screen brightness. This is not limited here.

[0090] In the embodiment of the present invention, when it is detected that the second relative angle of the driver has significantly deflected and exceeds the set reasonable angle range related to the co-pilot screen, the system will consider that the driver's attention may have been transferred to the outside of the vehicle or other screens. At this time, it is meaningless to continue to control the brightness of the co-pilot screen, so the system will automatically exit the intelligent control mode of the brightness of the co-pilot screen. That is, when the driver is no longer focused on the co-pilot screen, the system can intelligently stop adjusting its brightness to prevent visual interference caused by sudden changes in screen brightness when the driver's vision is distracted.

[0091] Optionally, in step S13, performing brightness grading control on the target screen and screens other than the target screen may include the following execution steps:

[0092] The display brightness of the target screen is adjusted to a first preset brightness, and the display brightness of the screen outside the target screen is adjusted to a second preset brightness, wherein the first preset brightness is stronger than the second preset brightness.

[0093] In an embodiment of the present invention, the first preset brightness can be understood as the brightness set by the system for the target screen. Exemplarily, the first preset brightness is usually set to a higher value, aiming to ensure that when the system determines that the driver is looking at a certain screen (i.e., the target screen), the screen can provide clear and easy-to-read information to meet the driver's needs in navigation, entertainment, vehicle status monitoring, etc. The setting of the first preset brightness takes into account the lighting conditions in different driving environments, and ensures that the information is prominent enough in the driver's field of vision to quickly obtain important information, especially when driving at night or in low-light environments. In addition, in order to reduce the driver's visual fatigue when operating the screen, the first preset brightness is usually adjusted according to the light level of the surrounding environment, but generally it will be higher than the second preset brightness, which is not limited here.

[0094] The second preset brightness can be understood as the brightness set by the system for display screens other than the target screen. Exemplarily, compared with the first preset brightness, the second preset brightness level is set to a lower value and is applicable to other screens other than the target screen. The system adopts this brightness control strategy in order to reduce the visual interference of non-target screens to the driver, especially at night or in low light conditions, where overly bright screens may distract the driver and increase driving risks. The setting of the second preset brightness ensures that even if other screens are displaying information, they will not attract the driver's attention due to excessive brightness, allowing the driver to focus more on driving and tasks on the target screen.

[0095] Adjusting the display brightness of the target screen to the first preset brightness can be understood as the vehicle intelligently analyzing the driver's facial orientation, determining the screen that the driver is currently paying attention to, and adjusting the brightness of the screen to a pre-set, higher brightness level.

[0096] Adjusting the display brightness of screens outside the target screen to a second preset brightness can be understood as, for example, the intelligent system inside the vehicle can automatically adjust the display brightness of screens not directly concerned according to the driver's line of sight, and reduce visual interference by setting a lower second preset brightness, which is not limited here.

[0097] The display brightness of the target screen is adjusted to a first preset brightness, and the display brightness of the screen outside the target screen is adjusted to a second preset brightness, wherein the first preset brightness is stronger than the second preset brightness, which can be understood as, for example, adjusting the display brightness of the screen that the driver is currently looking at to the first preset brightness, and adjusting the display brightness of the screen that the driver is not currently looking at to the second preset brightness, and the first preset brightness level is stronger than the second preset brightness level, which is not limited here.

[0098] In an embodiment of the present invention, by adjusting the display brightness of the target screen to a first preset brightness, and adjusting the display brightness of the screen outside the target screen to a second preset brightness, wherein the first preset brightness is stronger than the second preset brightness, not only is the driver's visual experience optimized and driving safety improved, but also a more comfortable, safe and energy-saving driving environment can be created.

[0099] Optionally, the screen brightness adjustment method further includes:

[0100] When the driver is facing the first camera, the first relative angle is a negative angle when the driver turns his head to the left, and the first relative angle is a positive angle when the driver turns his head to the right. When the driver is facing the second camera, the second relative angle is a negative angle when the driver turns his head to the left, and the second relative angle is a positive angle when the driver turns his head to the right.

[0101] In an embodiment of the present invention, when the driver is facing the first camera, the first relative angle is a negative angle when the driver turns his head to the left, and the first relative angle is a positive angle when the driver turns his head to the right. It can be understood that inside the vehicle, when the driver's facial orientation is monitored by the first camera to intelligently adjust the screen brightness, the method for defining the angular relationship between the driver's head rotation direction and the camera is not restricted here.

[0102] When the driver is facing the second camera, the second relative angle is a negative angle when the driver turns his head to the left, and the second relative angle is a positive angle when the driver turns his head to the right. It can be understood that in the vehicle's internal camera system, when the second camera is used to monitor the driver's facial orientation, the definition rules for the angular relationship between the driver's head rotation direction and the camera are not restricted here.

[0103] In an embodiment of the present invention, by setting that when the driver faces the first camera, the first relative angle is a negative angle when the driver turns his head to the left, and the first relative angle is a positive angle when the driver turns his head to the right, and when the driver faces the second camera, the second relative angle is a negative angle when the driver turns his head to the left, and the second relative angle is a positive angle when the driver turns his head to the right, that is, by monitoring the head rotation angle of the driver facing different directions through two groups of cameras (the first camera and the second camera), the system can more accurately capture the changes in the driver's line of sight. This cross-positioning method improves the accuracy of angle measurement and ensures the accuracy of screen brightness adjustment. At the same time, the two cameras can work at the same time, effectively shortening the monitoring and response time, making the adjustment of the screen brightness more immediate, and improving the driving experience.

[0104] Optionally, the screen brightness adjustment method further includes:

[0105] The first camera is located on the left side of the instrument screen, the second camera is located on the right side of the instrument screen, the central control screen is located below the second camera, and the co-pilot screen is located on the right side of the central control screen.

[0106] In the embodiment of the present invention, the instrument screen can be exemplarily understood as a display screen located in front of the driver's seat and behind the steering wheel. It is the main source for the driver to obtain vehicle operating status information, such as vehicle speed, engine speed, fuel level, water temperature, mileage, warning signals, etc., which is not limited here.

[0107] The central control screen can be understood as a display screen located in the center console of the vehicle, facing the driver and co-pilot positions, which mainly provides multi-functional information interaction such as entertainment, navigation, vehicle settings, air conditioning control, etc., and is not limited here.

[0108] The co-pilot screen can be understood as a display screen located on the right side of the central control screen and facing the co-pilot position. The co-pilot screen is mainly used to provide entertainment and information functions for the co-pilot passenger, such as watching videos, browsing maps, controlling music, etc., which are not limited here.

[0109] In the embodiment of the present invention, by obtaining that the first camera is located on the left side of the instrument screen, the second camera is located on the right side of the instrument screen, the central control screen is located below the second camera, and the co-pilot screen is located on the right side of the central control screen, an accurate position distribution is provided for the system to subsequently determine the driver's facial orientation and change the brightness of different display screens.

[0110] Figure 2 is a schematic diagram of a sensor according to a screen brightness adjustment method according to an embodiment of the present invention. Figure 2As shown in the figure, the sensors mainly include DMS camera and OMS camera. Through the two in-car cameras DMS and OMS, based on image recognition technology, the user's facial orientation data is collected in real time. The facial orientation angle range is divided for each display screen. When the user faces a certain display screen, the corresponding screen brightness is adjusted to the first target brightness, and the remaining screens are kept at low brightness, thereby improving the driving experience.

[0111] The DMS camera and OMS camera in the sensor are used to cross-locate the driver's facial orientation. By analyzing the head's rotation angle, tilt degree and other information, combined with the position distribution of the screens in the car, the screen the user is facing is inferred. The DMS and OMS cameras collect the deflection angle of the driver's facial orientation in real time. When facing the camera vertically from the main driving position, a deflection to the left is a negative angle, and a deflection to the right is a positive angle. Based on the calibration strategy of the screen position distribution, it is possible to accurately determine which screen the driver is looking at.

[0112] Figure 3 is a schematic diagram of the implementation principle of a screen brightness adjustment method according to an embodiment of the present invention. Figure 3 As shown, when the driver is at a positive angle with the DMS camera and a negative angle with the OMS camera, it means that the driver is looking at the instrument screen, and the system sets the instrument screen to the first preset brightness. When the driver is at a positive angle with the OMS camera, and the angle is less than the first angle threshold (i.e., f°-calibrated value), it means that the driver is looking at the central control screen, and the system sets the central control screen to the first preset brightness. When the driver is at a positive angle with the OMS camera, and the angle is greater than or equal to the first angle threshold (i.e., f°-calibrated value), and less than or equal to the second angle threshold (i.e., f°+calibrated value), it means that the driver is looking at the co-pilot screen, and the system sets the co-pilot screen to the first preset brightness. When the driver is at a positive angle with the OMS camera and the angle is greater than or equal to the second angle threshold (i.e., f°+calibrated value), it means that the driver is looking at the co-pilot screen, and the system sets the co-pilot screen to the first preset brightness. When the driver is at a greater than or equal to the second angle threshold (i.e., f°+calibrated value), it means that the driver is not looking at any screen in the car, and the system exits the screen brightness control.

[0113] In the embodiment of the present application, the DMS camera and the OMS camera can accurately determine the direction of the user's face. The present application can be used to solve the problem of accurately judging which screen the user needs to control when it is inconvenient to click the screen with your hand, improve driving safety and convenience, and the present invention can also be based on this feature, and can be expanded and innovated in many "facing +" scenarios. For example, the voice gaze function, when the face is facing the screen, the visible and speak function is activated to directly control the function on the screen, or when there is a function on the current screen that you don't understand, directly voice Q&A. In addition, the present application can also be provided to all functions that need to judge the relationship between the user's facial orientation and the screen, that is, it can not only be used in brightness adjustment, but also in functions such as staring at the screen to light up (the default screen is off to save power when not staring), and it can also be expanded to voice gaze problems, and the visible and speak voice function of the screen can be activated when the face is facing a certain screen.

[0114] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.
