[0038] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0039] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0040] Based on the background technology, in real life, when riding in a vehicle, users need to use mobile devices for office or business, such as mobile phones or tablet computers. In order to prevent the contents of mobile phones or tablet computers from being seen by others, some passengers will use their mobile phones or tablet computers toward and near the car window. However, since the car window glass is transparent, when the light is dim, the transparent car window glass will reflect objects with higher brightness. Since the screen brightness of the user's mobile phone or tablet computer is high, the screen brightness of the mobile phone or tablet computer will be higher than the brightness of the light inside the car, then the car window glass will reflect the screen of the mobile phone or tablet computer, and passengers in other seats may clearly see the reflected content of the screen on the car window glass, which will lead to the leakage of the user's personal privacy.

[0041] In order to solve the above technical problems, Figure 1 As shown, the present application provides a vehicle glass adjustment method, comprising the following steps:

[0042] Step 102: Acquire the image of the vehicle window glass and the vehicle interior environment information in real time.

[0043] In this step, the vehicle control system includes an acquisition unit, an image processing unit and a vehicle controller. The acquisition unit may include a camera installed in the vehicle, the camera captures the image of the window glass in real time, and sends the captured image of the window glass to the image processing unit, and the image processing unit detects whether the image of the window glass contains the mobile terminal screen reflection image. Among them, multiple cameras can be set, each window can correspond to a camera, or one side window corresponds to a camera, which can be set according to actual conditions, and is not specifically limited in this application. The in-vehicle information includes the in-vehicle light brightness information, the mobile terminal screen status, and the distance between the mobile terminal and the window glass. The acquisition unit may also include a light detection sensor installed in the vehicle, and the light detection sensor monitors the in-vehicle light brightness information in real time and transmits it to the vehicle controller. The camera captures the image of the seating area in real time and transmits the captured image to the image processing unit. Among them, the camera includes multiple cameras, each camera can correspond to a row of seating areas. The image processing unit processes the captured image of the seating area, determines the state of the mobile screen (the mobile screen state includes a lit state or an unlit state), and determines the distance between the mobile terminal and the vehicle window glass (exemplarily, a first position point is set at the edge of the mobile terminal and a second position point is set at the edge of the vehicle window glass, and the distance between the first position point and the second position point is calculated).

[0044] Step 104: In response to detecting that the image of the vehicle window glass includes a mobile terminal screen reflection image, determining the clarity of the mobile terminal screen reflection image.

[0045] In this step, when the image processing unit detects that the image of the vehicle window glass contains the reflected image of the mobile screen, it further detects the clarity of the reflected image of the mobile screen and feeds back the detected clarity to the vehicle controller. The vehicle controller can adjust the transparency of the vehicle window glass according to the clarity.

[0046] Step 106: In response to the clarity of the image reflected by the mobile terminal screen being greater than a preset threshold, the transparency of the vehicle window glass is lowered according to the clarity and the in-vehicle information.

[0047] In this step, after the vehicle controller receives the clarity of the image reflected on the mobile screen fed back by the image processing unit, it compares the clarity of the image reflected on the mobile screen with a preset threshold. When the clarity of the image reflected on the mobile screen is greater than the preset threshold, the transparency of the window glass is lowered according to the clarity and the information inside the vehicle. In this way, the transparency of the window glass can be lowered to an appropriate transparency according to the clarity and the information inside the vehicle, so as to reduce the clarity of the image reflected on the mobile screen to a blurred level, protect the user's personal privacy, and avoid over-adjusting the transparency of the window glass, which would reduce the user's visual comfort.

[0048] Furthermore, the vehicle in the present application is equipped with smart glass, which is specifically described as follows: For example, the principle of liquid crystal dimming glass is adopted: Liquid crystal dimming glass is a technology that changes the transparency of glass under the action of an electric field by embedding liquid crystal material in the glass. When the electric field acts, the liquid crystal molecules are arranged neatly and the glass is transparent; by controlling the voltage of the electric field, the arrangement sparseness of the liquid crystal molecules can be controlled, thereby changing the transparency of the glass; when the electric field is turned off, the liquid crystal molecules are arranged disorderly and the glass becomes opaque.

[0049] Glass structure: Liquid crystal dimming glass is usually composed of a multilayer structure, including two glass layers and a liquid crystal layer sandwiched in between. In this application, the liquid crystal layer takes cholesteric liquid crystal as an example. Cholesteric liquid crystal has a spiral structure and can selectively reflect light of a specific wavelength. This reflection characteristic is closely related to the spiral arrangement of the liquid crystal molecules. When the liquid crystal molecules are arranged regularly, the reflectivity is high; conversely, when the arrangement is irregular, the reflectivity is low. Cholesteric liquid crystal has a unique spiral structure, which enables the liquid crystal molecules to selectively reflect light of a specific wavelength, forming the so-called Bragg reflection. However, when the liquid crystal molecules are arranged regularly, their scattering effect on light will be weakened, because the regularly arranged molecules can more effectively guide light through the liquid crystal layer instead of scattering it in all directions. When the cholesteric liquid crystal molecules are arranged regularly, the interaction between them reduces the scattering of light by the liquid crystal layer, and the light can pass through the liquid crystal layer more smoothly. In this state, the transmittance of the liquid crystal layer will be relatively high. On the contrary, if the liquid crystal molecules are arranged disorderly, the interaction between them will enhance the scattering effect on light, causing the light to encounter more obstacles when passing through the liquid crystal layer, thereby reducing the transmittance.

[0050] Through steps 102-106, the image of the vehicle window glass and the information inside the vehicle are obtained in real time, and it is detected whether the image of the vehicle window glass contains the mobile terminal screen reflection image. When it is detected that the image of the vehicle window glass contains the mobile terminal screen reflection image, the clarity of the mobile terminal screen reflection image is further detected to determine the clarity of the mobile terminal screen reflection image; in this way, the transparency of the vehicle glass can be adjusted according to the clarity of the mobile terminal screen reflection image. Since cholesteric liquid crystal is used in this application, the cholesteric liquid crystal has a spiral structure. When the liquid crystal molecules are arranged irregularly, the transparency of the vehicle window glass is low, and the reflectivity and transmittance are low; when the liquid crystal molecules are arranged regularly, the higher the transparency of the vehicle window glass, the higher the reflectivity and transmittance, that is, the higher the transparency of the vehicle window glass, the clearer the reflected mobile terminal screen image, the lower the transparency of the vehicle window glass, the more blurred the reflected mobile terminal screen image, therefore, when the clarity is greater than the preset threshold, according to the clarity and the information inside the vehicle, the transparency of the vehicle window glass is lowered, so that the transparency of the vehicle window glass is lowered, the clarity of the mobile terminal screen reflection image can be reduced, thereby achieving the purpose of protecting personal privacy.

[0051] In some embodiments, based on step 104, the image processing unit detects the clarity of the image reflected from the mobile terminal screen, wherein the image processing unit includes a preset model, and when determining the clarity of the image reflected from the mobile terminal screen, the image processing unit includes:

[0052] The mobile terminal screen reflected image is detected using a preset model to obtain the clarity of the mobile terminal screen reflected image.

[0053] Specifically, the preset model is a model obtained by multiple rounds of training with training samples, that is, the preset model is a pre-trained model. Among them, the training samples include data collected on various models, and multiple cameras are respectively set on various models, and the cameras are used to collect relevant data of passengers using mobile devices in the car in various environments in various models. Among them, various environments include daytime, night, sunny days and rainy days, etc., and the relevant data of passengers using mobile devices in the car include: passengers sitting in different seats using mobile devices, the operating status of mobile devices, etc., and the reflection image of mobile devices on the car window glass under various environmental information. By collecting the above-mentioned environmental images, the diversity of data can be ensured, and the model can be trained using these data to make the trained model more accurate. Among them, the preset model can use embedded hardware such as NVIDIAJetson Nano or Raspberry Pi for real-time inference of the model to ensure that the system runs with low latency and high accuracy.

[0054] Further, the above-mentioned collected images are preprocessed, including denoising, cropping, enhancement and other operations. The denoising technology can use convolutional neural network (CNN) to reduce image noise, and the cropping and enhancement operations can be performed using image processing libraries such as OpenCV. Data annotation is performed on the preprocessed training samples, and the image data is annotated using a semi-automatic annotation tool to generate a high-quality annotated sample data set. The annotation tool can use a bounding box annotation method to accurately annotate the reflective area in each image and generate annotated training samples. In this application, the YOLO V4 target detection algorithm is used, and the model training is iteratively trained and verified using annotated training samples to obtain a trained preset model. In this way, the model is trained using annotated training samples, so that the preset model recognition accuracy is higher. When the preset recognition model is used to detect the reflected image of the mobile screen, a more accurate clarity can be fed back, which enables the vehicle controller to accurately control the transparency of the window glass.

[0055] In some embodiments, since cholesteric liquid crystal is used in the present application, and cholesteric liquid crystal has a spiral structure, when the liquid crystal molecules are arranged irregularly, the transparency of the car window glass is low, and the reflectivity and transmittance are low; when the liquid crystal molecules are arranged regularly, the transparency of the car window glass is high, and the reflectivity and transmittance are high. That is, the transparency of the car window glass is too large, which will lead to the clarity of the image reflected on the mobile screen. Therefore, when the clarity of the image reflected on the mobile screen is greater than the preset threshold, it means that the clarity is clearer and the transparency of the car window glass is greater. Then it is necessary to lower the transparency of the car window glass to reduce the clarity of the image reflected on the mobile screen to protect the privacy of the user. The specific adjustment is as follows: the in-car information includes: the brightness information of the light in the car;

[0056] The step of lowering the transparency of the vehicle window glass according to the clarity and the vehicle interior information includes:

[0057] Determining a target transparency adjustment amplitude according to the clarity, the interior light brightness information and a preset transparency adjustment amplitude correspondence relationship;

[0058] According to the target transparency adjustment amplitude value, the transparency of the vehicle window glass is lowered.

[0059] Specifically, in this embodiment, the preset corresponding relationship of the transparency adjustment amplitude value can be a relationship table pre-stored in the memory, and the relationship table (such as the first relationship table shown in Table 1) stores the corresponding relationship between the brightness information of the light in the car, the clarity and the transparency adjustment amplitude. According to the clarity and the brightness information of the light in the car obtained in real time, the relationship table is searched, and the transparency adjustment amplitude corresponding to the range in which the clarity and the brightness of the light in the car fall is used as the target transparency adjustment amplitude, and the transparency of the car window glass is lowered according to the target transparency adjustment amplitude. In this embodiment, the transparency of the car window glass can be lowered multiple times according to the target transparency amplitude until the clarity is less than the preset threshold value, and the preset threshold value is the limit value that makes the reflected image of the mobile terminal screen of the car window glass blurry. In this way, the transparency of the car window glass can be adjusted in a small range to avoid large adjustments, which will cause visual discomfort to the user.

[0060] Table 1 The first relationship table

[0061]

[0062] In some embodiments, when adjusting the transparency of the vehicle window glass, it is not necessary to adjust all the vehicle window glass. If all the vehicle window glass is adjusted, it will cause the interior of the vehicle to be too dark, and it will also increase the workload of the vehicle controller and increase the vehicle's operating energy consumption. Therefore, it is necessary to first determine the vehicle window glass that needs to be adjusted, and then adjust the determined vehicle window glass. In this way, the vehicle's operating energy consumption can be reduced, and the user can also have a better riding experience. The specific adjustment process is as follows: According to the target transparency adjustment amplitude value, the transparency of the vehicle window glass is lowered, including:

[0063] The window glass whose clarity of the image reflected by the mobile terminal screen is greater than a preset threshold is used as the target window glass;

[0064] According to the target transparency adjustment amplitude, the transparency of the target vehicle window glass is lowered.

[0065] Specifically, after receiving the clarity of the image reflected from the mobile screen, the vehicle controller compares the clarity with a preset threshold. If the clarity is greater than the preset threshold, it means that the transparency of the window glass is high, resulting in a clearer reflected image. Therefore, the transparency of the window glass needs to be lowered. When adjusting the window glass, the window glass with a clarity greater than the preset threshold is used as the glass that needs to be adjusted, that is, as the target window glass. According to the target transparency adjustment amplitude, the transparency of the target window glass is lowered. In this way, when determining the window glass that needs to be adjusted, since the user is using a mobile device, the user will not appreciate the scenery outside the car, and adjusting the window glass to opaque does not affect the user's riding experience. Before adjusting the window glass, first accurately determine the window glass that needs to be adjusted, and then accurately control the window glass that needs to be adjusted according to the target transparency adjustment amplitude value, avoiding the adjustment of all window glasses. The transparency of the window glass corresponding to other users who do not use mobile devices remains unchanged, allowing other users to appreciate the scenery outside the car. In this way, the running energy consumption of the vehicle can be reduced, and at the same time, the user can have a better riding experience.

[0066] In some embodiments, Figure 2 As shown, when it is detected that the image of the car window glass does not contain the reflected image of the mobile terminal screen, the user may not be using the mobile device or the mobile device is far away from the car window. This situation will not lead to the leakage of user privacy. If the transparency of the car window glass is low, the transparency of the car window glass can be improved so that the user can see the scenery outside the car through the car window glass during the ride, thereby improving the user's experience. Based on this, the method described in this application also includes the following steps:

[0067] 202. In response to detecting that the image of the vehicle window glass does not include a mobile terminal screen reflection image, judging whether the vehicle window glass meets a transparency adjustment condition according to the vehicle interior information;

[0068] 204. In response to the vehicle window glass satisfying an adjustment condition for increasing transparency, the transparency of the vehicle window glass is increased according to the clarity and the in-vehicle information.

[0069] Specifically, the image processing unit detects that the image of the window glass does not contain the reflected image of the mobile terminal screen, and feeds back information that the reflected image of the mobile terminal screen is not detected to the vehicle controller. After receiving the information that the reflected image of the mobile terminal screen is not detected as fed back by the image processing unit, the vehicle controller determines whether the window glass meets the adjustment conditions for increasing the transparency based on the information inside the vehicle. When the window glass meets the adjustment conditions for increasing the transparency, the transparency of the window glass is increased. In this way, when the image of the window glass does not contain the reflected image of the mobile terminal screen and the window glass meets the adjustment conditions for increasing the transparency, the user's privacy can be ensured not to be leaked. At the same time, improving the transparency of the window glass can also allow users to appreciate the beautiful scenery outside the vehicle more intuitively, thereby improving the user's riding experience.

[0070] In some embodiments, when judging whether the vehicle window glass meets the adjustment conditions for increasing transparency, it can be understood as judging whether the user has turned on the mobile device again in a short period of time, and whether the mobile device is close to the vehicle window glass. If so, the adjustment conditions for increasing transparency are not met. If not, the adjustment conditions for increasing transparency are met. For example, if the vehicle window glass does not meet the adjustment conditions for increasing transparency, the transparency of the vehicle window glass is increased, and the screen of the mobile device will still be reflected on the vehicle window glass, resulting in the leakage of user privacy. If the mobile device repeatedly turns on the screen, the vehicle controller will continuously adjust the vehicle window glass, which will affect the service life of the vehicle window glass. Based on this, the specific process of judging whether the vehicle window glass meets the requirements for increasing transparency is as follows: the in-vehicle information includes the screen status of the mobile terminal, and the distance between the mobile terminal and the vehicle window glass;

[0071] The determining, based on the in-vehicle information, whether the vehicle window glass meets the adjustment condition for increasing transparency includes:

[0072] In response to the mobile terminal screen being in an unlit state and lasting for a period longer than a first preset period, or,

[0073] The distance between the mobile terminal and the vehicle window glass is continuously greater than the preset distance within a second preset time period, and it is determined that the vehicle window glass meets the adjustment condition for increasing transparency.

[0074] Specifically, the in-car camera will capture the in-car image and transmit the image to the image processing unit, which analyzes and processes the image to obtain the mobile terminal screen state and the distance between the mobile terminal and the window glass, and feeds back the data obtained from the analysis and processing to the vehicle controller. The vehicle controller determines whether the window glass meets the adjustment condition of increasing transparency according to the mobile terminal screen state and the distance between the mobile terminal and the window glass. When the mobile terminal screen state is not lit and the duration is greater than the first preset duration (exemplarily, the first preset duration is 1min), it means that the screen of the mobile device used by the user is turned off and the off duration is greater than 1min, which means that the user is not using the mobile device, then the transparency of the window glass can be increased, and it is determined that the window glass meets the adjustment condition of increasing transparency. When the distance between the mobile terminal and the window glass is continuously greater than the preset distance (exemplarily, the preset distance is 10cm) within the second preset duration (exemplarily, the second preset duration is 2min), it means that the mobile device used by the user is far away from the window glass, then no reflected image will be generated on the window glass, and the transparency of the window glass can be increased, and it is determined that the window glass meets the adjustment condition of increasing transparency. In this way, by judging whether the vehicle window glass meets the conditions for adjusting the transparency, the repeated operation of the vehicle window glass controller can be reduced and the service life of the vehicle window glass can be increased.

[0075] In some embodiments, when the transparency of the vehicle window glass is increased, it can be adjusted according to the adjustment range. In this way, it is possible to avoid the problem that the adjustment range is too large, causing visual discomfort to the user and affecting the user's experience. Therefore, when the transparency of the vehicle window glass is increased, the adjustment range can be determined first, and then the transparency of the vehicle window glass is adjusted according to the adjustment range. The specific adjustment process is as follows: the in-vehicle information includes: in-vehicle light brightness information;

[0076] The step of increasing the transparency of the vehicle window glass according to the clarity and the vehicle interior information includes:

[0077] Determining a target transparency adjustment amplitude according to the clarity, the interior light brightness information and a preset transparency adjustment amplitude correspondence relationship;

[0078] According to the target transparency adjustment amplitude value, the transparency of the vehicle window glass is increased.

[0079] Specifically, in this embodiment, the preset corresponding relationship of the transparency adjustment amplitude value can be a relationship table pre-stored in the memory, and the relationship table (such as the second relationship table shown in Table 2) stores the corresponding relationship between the brightness information of the light inside the car, the clarity and the transparency adjustment amplitude. According to the clarity and the brightness information of the light inside the car acquired in real time, the relationship table is searched, and the transparency adjustment amplitude corresponding to the range in which the clarity and the brightness of the light inside the car fall is used as the target transparency adjustment amplitude, and the transparency of the car window glass is increased according to the target transparency adjustment amplitude. In this embodiment, the transparency of the car window glass can be increased multiple times according to the target transparency amplitude until the transparency of the car window glass is the highest, that is, completely transparent, so that when the user is in the car to visit the scenery outside the car, the vision is better, and the user's riding experience is improved.

[0080] Table 2 Second relationship table

[0081]

[0082] It should be noted that the first relationship table and the second relationship table in the above embodiment may be the contents of one table, and some illustrative contents are selected for different embodiments in this application.

[0083] In some embodiments, when adjusting the transparency of the vehicle window glass, it is not necessary to adjust all the vehicle window glass. If all the vehicle window glass is adjusted, it will cause the interior of the vehicle to be too dark, and it will also increase the workload of the vehicle controller and increase the vehicle's operating energy consumption. Therefore, it is necessary to first determine the vehicle window glass that needs to be adjusted, and then adjust the determined vehicle window glass. In this way, the vehicle's operating energy consumption can be reduced, and the user can also have a better riding experience. The specific adjustment process is as follows: According to the target transparency adjustment amplitude value, the transparency of the vehicle window glass is increased, including:

[0084] The window glass that does not contain the reflected image of the mobile terminal screen is used as the target window glass;

[0085] The target transparency of the vehicle window glass is increased according to the target transparency adjustment amplitude.

[0086] Specifically, when the vehicle controller receives information that the window glass does not contain the reflected image of the mobile terminal screen, it means that the user is not using the mobile device or the user is far away from the window when using the mobile device, and the screen of the mobile device will not be reflected to the window glass. At this time, the transparency of the window glass can be increased to ensure that the user can enjoy the scenery outside the car and improve the user experience. When adjusting the window glass, the window glass that does not contain the reflected image of the mobile terminal screen is used as the glass that needs to be adjusted, that is, as the target window glass, and the transparency of the target window glass is increased according to the target transparency adjustment amplitude. In this way, when determining the window glass that needs to be adjusted, since the user does not use the mobile device or the mobile device is far away from the window, the user may enjoy the scenery outside the car. Therefore, the window glass that needs to be adjusted is first accurately determined, and then the window glass that needs to be adjusted is accurately controlled according to the target transparency adjustment amplitude value, avoiding the adjustment of all window glasses. The transparency of the window glass for other users using mobile devices remains unchanged, which can ensure the personal privacy of other users. In this way, the running energy consumption of the vehicle can be reduced, and the user can also have a better riding experience.

[0087] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.

[0088] It should be noted that the above describes some embodiments of the present application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
