[0079] The present application is described more clearly below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the effects of the present application, but are not intended to limit the present application in any form. It should be noted that, for those of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present application.

[0084] In addition, the “plurality” mentioned in the embodiments of the present application should be interpreted as two or more.

[0085] As a vehicle interior, the starry sky ceiling provides lighting and enhances the atmosphere in the car. However, the display of the starry sky ceiling is usually limited to fixed patterns, and the display effect is single, which cannot meet the diverse needs of users and cannot create a unique in-car experience for users.

[0086] With the idea of ​​meeting users' diverse demands for the display of the starry sky ceiling, the inventor discovered through research that relevant images can be generated based on the road signs at the vehicle's location, as well as the geographical location and surrounding landmarks, and combined with the starry sky ceiling's current mode, the starry sky ceiling can be controlled to display the image, so as to display distinctive and situational images in combination with the vehicle's location, thereby improving the in-car atmosphere, meeting users' diverse demands for the starry sky ceiling, and creating a unique in-car experience for users.

[0087] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0088] First reference Figure 1 , Figure 1 An application scenario of the present application is schematically illustrated, in which a controller and a starry sky top are included.

[0089] The controller is connected to the starry sky ceiling to control the display of the starry sky ceiling. The starry sky ceiling includes multiple lamp heads, each of which is connected to multiple optical fibers, and the display points of the optical fibers corresponding to each lamp head are arranged into a display strip on the vehicle ceiling. The display points of the multiple optical fibers connected to each lamp head are in a row or a column, which is called a display strip, and all display strips constitute a display array.

[0090] The controller obtains the road signs at the vehicle's current location, as well as location-related data, such as geographic location and surrounding landmarks. It then extracts features from the road signs, obtains target features, and generates images based on the target features, geographic location, and surrounding landmarks. It then controls the display of the starry sky ceiling according to the starry sky ceiling's current mode and image to enhance the interior atmosphere of the vehicle and meet users' diverse needs for the starry sky ceiling.

[0091] Optionally, the controller determines a dot matrix based on the generated image, and then determines the target display point according to the dot matrix, and controls the target lamp head corresponding to the target display point to light up the corresponding target display point to display the image. That is, the controller decomposes the generated image into a dot matrix, and corresponds each dot unit on the dot matrix to the display array, determines multiple target display points, and controls the target lamp head corresponding to the target display point to light up the corresponding target display point to display the generated image. That is, each target lamp head displays a pattern, and the patterns displayed by all target lamp heads constitute the above image.

[0092] For example, the controller can be an on-board controller, an off-board controller, or a combination of an on-board controller and an off-board controller, and is a hardware device with data storage, processing, and analysis functions. Here, the controller is an on-board controller as an example, which can be a multimedia head unit system (HUT) or an electronic control unit (ECU).

[0093] The controller may be built with a map database to obtain the road sign of the vehicle's current location based on the vehicle's current location and the map database. The controller may also be built with a natural language processing (NLP) model and an information fusion processing model to extract features of the road sign using the NLP model to obtain target features, and to generate images based on the target features, geographic location, and surrounding landmarks using the information fusion processing model.

[0094] Combine the following Figure 1 ,refer to Figure 2-Figure 3To describe the display control method of the vehicle starry sky ceiling provided according to an exemplary embodiment of the present application.

[0095] Figure 2 It is a flow chart of a display control method of a vehicle starry sky ceiling provided in one embodiment of the present application.

[0096] like Figure 2 As shown, the method in the embodiment of the present application may include:

[0097] Step 201: Obtain the road sign of the vehicle's current location and data related to the location; wherein the data includes the geographic location and surrounding landmarks.

[0098] In this embodiment, after the vehicle is started, such as during the driving process, the location information of the current location of the vehicle can be obtained through the positioning system, such as the Global Positioning System (GPS). Afterwards, based on the obtained location information and the map database, the road sign of the current location of the vehicle is obtained, and the road sign may include the road name, etc. And based on the obtained location information and the map database, the geographical location and surrounding landmarks related to the current location of the vehicle are obtained. The geographical location may be the city, town, etc. where the vehicle is currently located, and the surrounding landmarks may be landmarks within a preset distance range of the current location of the vehicle, such as iconic buildings and landscapes.

[0099] Step 202: extract features of road signs to obtain target features.

[0100] In this embodiment, the road sign may be a road name, and the target feature may be a keyword.

[0101] In some embodiments, feature extraction is performed on road signs, and road names can be segmented and tagged with parts of speech to obtain segmented words tagged with parts of speech. Among the segmented words tagged with parts of speech, except for preset segmented words, the segmented words with preset parts of speech are used as target words, and the priority of the part of speech of the target words is determined. Thereafter, based on the priority of the part of speech of the target words, keywords are obtained from the target words and used as target features.

[0102] Exemplarily, this embodiment first performs word segmentation processing on the road names, and divides the road names into different word segments. For example, for Sakura Avenue, it can be divided into three word segments, "Sakura", "Big" and "Road", and for Chaoyang Road, it can be divided into two word segments, "Chaoyang" and "Road". After that, the obtained word segments are tagged with parts of speech, for example, the word "Sakura" is marked as a noun, "Big" is marked as an adjective, and "Road" is marked as a noun. Among them, word segmentation processing and part of speech tagging can be performed using NLP models, etc. The NLP model can extract information from the text data by analyzing the text data, and make corresponding predictions or decisions.

[0103] In this embodiment, the preset participle may be a noun representing a road, such as the preset participle may include road, road, street, lane, lane, alley, and lane. The preset parts of speech may include nouns, adjectives, and numerals, and the priority of the parts of speech may be that the priority of nouns is greater than the priority of adjectives, and the priority of adjectives is greater than the priority of numerals. Here, the preset parts of speech are set to include nouns, adjectives, and numerals, because the participles corresponding to these parts of speech can usually represent the characteristics of the road. When determining the target word, first remove the noun representing the road, and then select the participle of the preset part of speech from the remaining participles as the target word. When determining the keyword, take the target word with the highest priority of the part of speech as the keyword, so that the obtained keyword can better represent the characteristics of the road as the target feature.

[0104] For example, for the obtained participles "cherry blossom", "big" and "road", the noun "cherry blossom" and the adjective "big" are used as target words, and the priority of nouns is higher than that of adjectives, so "cherry blossom" is used as the keyword, that is, as the target feature.

[0105] Step 203: Generate an image based on target features, geographic location and surrounding landmarks.

[0106] For example, different cities and towns have different characteristics, such as tourist cities, industrial cities, and historical and cultural cities, and different geographical locations can also represent the characteristics of the vehicle's location. In addition, different geographical locations may have the same road names, but due to different geographical locations, the meanings of these road names are also different. Similarly, surrounding landmarks can also represent the characteristics of the vehicle's location. Therefore, this embodiment can consider the geographical location and surrounding landmarks while considering the road name, so that the generated image is more distinctive and contextual.

[0107] In some embodiments, an image is generated based on target features, geographic location and surrounding landmarks. Feature words corresponding to the geographic location can be determined from the preset correspondence between the geographic location and the feature words according to the geographic location, and feature words corresponding to the surrounding landmarks can be determined from the preset correspondence between the landmarks and the feature words according to the surrounding landmarks. Then, an image is generated based on the target features, the feature words corresponding to the geographic location and the feature words corresponding to the surrounding landmarks.

[0108] Exemplarily, the correspondence between the preset geographical location and the characteristic words indicates the geographical location and the characteristic words that can characterize its characteristics. For example, if the geographical location is city A, the corresponding characteristic words may be "ancient capital", "culture" and "peony", etc. Similarly, the correspondence between the preset landmarks and the characteristic words indicates the landmarks and the characteristic words that can characterize their characteristics. For example, if the surrounding landmark is building B, the corresponding characteristic words may be "Legend of the White Snake", "sunset", etc.

[0109] In this way, after determining the characteristic words corresponding to the geographical location and the characteristic words corresponding to the surrounding landmarks, the target features are combined to jointly generate relevant images.

[0110] In some embodiments, when generating an image, target features, characteristic words corresponding to the geographic location, and characteristic words corresponding to surrounding landmarks may be input into a preset information fusion processing model to obtain an image output by the information fusion processing model.

[0111] Here, the information fusion processing model can be an artificial intelligence large model, which is a machine learning model with ultra-large-scale parameters and complex computing structure. The information fusion processing model can be trained based on the characteristics of road signs at different locations, the characteristic words corresponding to the corresponding geographical locations and the characteristic words corresponding to the surrounding landmarks, and the corresponding images. By inputting the target features, the characteristic words corresponding to the geographical locations and the characteristic words corresponding to the surrounding landmarks into the information fusion processing model, an image associated with the target features, the characteristic words corresponding to the geographical locations and the characteristic words corresponding to the surrounding landmarks can be obtained, and the image is richer in the characteristics and context of the vehicle's location.

[0112] Step 204: Control the display of the starry sky top according to the current mode and image of the starry sky top.

[0113] Exemplarily, the modes of the starry sky ceiling may include static mode and dynamic mode, etc. Different modes have different display effects of the images displayed by the starry sky ceiling. For example, if the mode of the starry sky ceiling is dynamic mode, the starry sky ceiling will flash and display the image; if the mode of the starry sky ceiling is static mode, the starry sky ceiling will statically display the image.

[0114] In this embodiment, the starry sky top is controlled to display the generated image according to the current mode of the starry sky top.

[0115] Optionally, before obtaining the road signs at the vehicle's current location and data related to the location, it is also possible to detect whether the road mode is activated. If the road mode is activated, the steps of obtaining the road signs at the vehicle's current location and data related to the location are executed. If the road mode is not activated, the starry sky top is controlled to display a preset pattern according to the current mode of the starry sky top, and the preset pattern is a pre-set pattern.

[0116] Exemplarily, this embodiment controls the starry sky roof to display the generated image according to the current mode of the starry sky roof until the vehicle drives to another road, repeats the steps of obtaining the road signs of the vehicle's current position and data related to the position, generates a new image, and controls the starry sky roof to display the new image.

[0117] The display control method of the vehicle starry sky ceiling provided in the embodiment of the present application generates relevant images according to the road signs at the vehicle's location, as well as the geographical location and surrounding landmarks, and controls the starry sky ceiling to display the image in combination with the current mode of the starry sky ceiling. It can display distinctive and situational images in combination with the vehicle's location, thereby improving the in-car atmosphere, meeting the user's diverse needs for the starry sky ceiling, and creating a unique in-car experience for the user.

[0118] In addition, in order to further meet the diverse needs of users for the starry sky ceiling, the display effect of the starry sky ceiling can be adjusted and optimized according to the different modes of the starry sky ceiling and the emotions of the passengers in the vehicle.

[0119] Figure 3 FIG. 1 is a flow chart of a method for controlling the display of a vehicle starry sky ceiling provided by another embodiment of the present application. Figure 3 As shown, the method in the embodiment of the present application may include:

[0120] Step 301: Obtain the road sign of the vehicle's current location and data related to the location; wherein the data includes the geographic location and surrounding landmarks.

[0121] Exemplarily, this embodiment can obtain the location information of the vehicle's current location through the positioning system, and then obtain the road signs of the vehicle's current location based on the obtained location information and the map database, as well as the geographical location and surrounding landmarks related to the vehicle's current location.

[0122] Step 302: extract features of road signs to obtain target features.

[0123] In this embodiment, the road sign may be a road name, and the target feature may be a keyword. First, the road name is segmented into different segmented words, and then the obtained segmented words are tagged with parts of speech. Among the segmented words tagged with parts of speech, except for the preset segmented words, the segmented words with the preset parts of speech are taken as target words, and the keywords are obtained from the target words according to the priority of the parts of speech of the target words, and the keywords are taken as target features.

[0124] Step 303: Generate an image based on target features, geographic location, and surrounding landmarks.

[0125] Optionally, in this embodiment, the target features, the characteristic words corresponding to the geographical location, and the characteristic words corresponding to the surrounding landmarks can be input into the artificial intelligence big model to obtain an image associated with the target features, the geographical location, and the surrounding landmarks output by the artificial intelligence big model. Among them, according to the geographical location, the characteristic words corresponding to the geographical location can be determined from the preset correspondence between the geographical location and the characteristic words, and according to the surrounding landmarks, the characteristic words corresponding to the surrounding landmarks can be determined from the preset correspondence between the landmarks and the characteristic words.

[0126] The specific implementation process and principles of steps 301 to 303 in this embodiment can refer to the relevant description in the above-mentioned embodiment, which will not be repeated here.

[0127] Step 304: Identify the emotions of the passengers in the vehicle.

[0128] Step 305, control the starry sky top display image, and according to the current mode of the starry sky top, control the dynamic and static effects of the starry sky top display image, and control the brightness of the starry sky top display image according to the mood.

[0129] Exemplarily, in this embodiment, the emotions of the passengers in the vehicle may include positive emotions and negative emotions. In order to better improve the atmosphere in the vehicle and further enhance the interaction with the passengers in the vehicle, the starry sky ceiling display image can also be controlled according to the emotions of the passengers.

[0130] In some embodiments, when the brightness of the starry sky top display image is controlled according to the emotion, it can be determined whether the emotion is a positive emotion. If the emotion is a positive emotion, the brightness of the starry sky top display image is controlled to be a first brightness. If the emotion is not a positive emotion, it is determined that the emotion is a negative emotion, and the brightness of the starry sky top display image is controlled to be a second brightness. The second brightness is higher than the first brightness.

[0131] In this embodiment, facial images of passengers in the vehicle can be collected by a camera, and then emotion recognition is performed on the collected facial images to obtain the emotions of each passenger, and the emotions of each passenger are classified to determine whether they are positive emotions. For example, positive emotions may include happiness, excitement, and tranquility, while negative emotions may include sadness, anger, and anxiety.

[0132] If it is recognized that the emotions of the passengers of a preset proportion or more are positive, the overall emotion is considered to be positive, indicating that the atmosphere in the car is relatively pleasant at this time, and the brightness of the starry sky ceiling display image is controlled to be the first brightness, that is, the brightness of the starry sky ceiling display image is controlled to be lower. Otherwise, the overall emotion is considered to be negative, indicating that the atmosphere in the car is relatively depressing at this time, and the brightness of the starry sky ceiling display image is controlled to be the second brightness, that is, the brightness of the starry sky ceiling display image is controlled to be higher, so as to adjust the atmosphere in the car and make the atmosphere in the car less depressing.
