[0042] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Reference Figure 1 , shows a flowchart of a method for controlling a vehicle projection lamp provided by an embodiment of the present invention, which may specifically include the following steps:

[0044] Step 101: Acquire a target instruction input by a user, and when the target instruction indicates to control a vehicle projection lamp, determine key text information in the target instruction.

[0045] Among them, the user refers to the person who uses and operates the vehicle, which may be the owner, driver, passenger or other individual who interacts with the vehicle. The needs and behaviors of vehicle users directly affect the purchase, use and maintenance decisions of the vehicle. In automobile design and vehicle services, it is crucial to understand the needs and behaviors of vehicle users. The target instruction input by the user refers to the specific operation instructions issued by the user to the system or device in some way (such as voice, text, gesture, etc.). The vehicle projection lamp refers to the lighting equipment installed on the vehicle, which is usually used to project patterns, signs or information onto the ground or other surfaces. It is common in high-end cars or special-purpose vehicles. The target instruction indicates the control of the vehicle projection lamp to realize the operation of the vehicle projection lamp, such as turning on, off, adjusting the brightness, changing the projection content, etc. Key text information refers to the text content used to indicate specific operations in the target instruction input by the user, such as simple "turn on the projection lamp", "turn off the projection lamp", "adjust the brightness to 50%", and personalized ones such as "greet your lover with warm lights", "greet the boss with solemn and majestic lighting effects", etc.

[0046] In some examples of this embodiment, the user can input a target instruction through the vehicle system or through a mobile terminal that can control the vehicle system, such as "greet your lover with warm lights" or "greet your boss with a solemn and majestic lighting effect", or the user can select a specific welcoming scene through the vehicle system or mobile terminal, such as welcoming friends, welcoming children, etc. "Greet your lover with warm lights" indicates that the vehicle user needs to control the vehicle projection lamp, and at this time, it is necessary to determine the key text information in the target instruction. For example, the key text information may refer to "greet", "lover", and "warmth".

[0047] Step 102: Generate lighting effect data for the vehicle projection lamp according to the key text information, and the lighting effect data matches the key text information.

[0048] The lighting effect data refers to the relevant data used to control the vehicle projection lamp to project, including but not limited to: switch state, brightness value, pattern data, etc.; the switch state indicates whether the projection lamp is on or off; the brightness value indicates the brightness level of the projection lamp; and the pattern data indicates the pattern or content to be displayed by the projection lamp. The lighting effect data matches the key text information in the target instruction input by the user.

[0049] In the specific implementation, if the target instruction input by the user is "greet your lover with warm lights", the generated lighting effect data will be a gentle pink lighting effect accompanied by soft light changes, matching the key text information "greet", "lover", and "warmth"; if the target instruction input by the user is "greet the boss with solemn and grand lighting effects", the generated lighting effect data will be a dark, atmospheric and simple lighting effect, highlighting the solemnity; when greeting children, lively and cute lighting effects will be generated, or lighting effects of cartoon characters that children like will be generated.

[0050] In some embodiments of the present application, step 102 may include the following sub-steps:

[0051] Sub-step 11: performing semantic analysis on the key text information to obtain lighting effect indication information;

[0052] Sub-step 12: generating lighting effect data for the vehicle projection lamp according to the lighting effect indication information.

[0053] In the specific implementation, a pre-trained vehicle-side lighting effect model can be deployed in advance in the vehicle. The vehicle-side lighting effect model is based on natural language processing and can parse the key text information input by the user to obtain the lighting effect indication information, and then generate personalized lighting effect data based on the parsed lighting effect indication information. A cloud-based large model can also be deployed in the cloud corresponding to the vehicle system. The cloud-based large model can generalize and understand complex language input, parse the key text information input by the user in the cloud, obtain the lighting effect indication information, and then generate personalized lighting effect data based on the parsed lighting effect indication information, and transmit the personalized lighting effect data to the vehicle control vehicle for projection.

[0054] For example, the vehicle-side lighting effect model and the cloud-based large model can automatically identify and respond to different inputs based on machine learning or deep learning technology to generate corresponding lighting effect data. In actual applications, a large number of input instructions and corresponding lighting effect data are first collected as training data, which are applied to the training of the vehicle-side lighting effect model and the cloud-based large model. Using the collected training data and machine learning or deep learning technology, the vehicle-side lighting effect model and the cloud-based large model are trained to recognize input instructions and generate corresponding lighting effect data. The trained model is called for actual application. Through pre-training, the model can learn the mapping relationship between input and output, and can provide intelligent lighting effect control, so that the vehicle projection lamp can automatically adjust and present appropriate projection effects according to different scenarios and needs.

[0055] In some embodiments of the present application, the lighting effect indication information includes application scenario information and emotion information, and sub-step 12 may include the following sub-steps:

[0056] Sub-step 111: Generate lighting effect data for the vehicle projection lamp according to the application scenario information and the emotion information.

[0057] In the specific implementation, the trained vehicle-side lighting effect model or the cloud-based large model parses the key text information input by the user, extracts the core emotions and scene requirements, and then generates personalized lighting effect data based on the parsed emotions and scene requirements. For example, when welcoming a lover, a gentle pink lighting effect is generated with soft light changes; when welcoming the boss, a dark-toned, atmospheric and simple lighting effect is generated to highlight the solemnity. In addition, the trained model can generalize and understand complex language input. In the two descriptions of "greeting a lover, the lighting effect should be warm and romantic" and "greeting a lover, I hope there will be some romantic lights", the cloud-based large model can understand their emotional similarities and scene similarities, and generate lighting effect data that meets expectations. In addition, the current time can also be used as a parameter to generate lighting effect data for vehicle projection lights. For example, a warm lighting effect is generated late at night, and a vibrant lighting effect is generated when the current time is in the morning.

[0058] In some embodiments of the present application, sub-step 11 may also include the following sub-steps:

[0059] Sub-step 211: semantically analyzing the key text information to obtain target action information and target user information;

[0060] Sub-step 212: Determine application scenario information and emotion information based on the target action information and the target user information.

[0061] In a specific implementation, the target action information refers to specific operation instructions extracted from the key text information, such as "open", "close", "greet", "welcome", etc., which in turn indicates the specific actions performed by the light projection system, such as controlling the projection lamp to turn on, off, or adjusting the projection lamp to a greeting mode, welcome mode, etc. The target user information refers to user-related information extracted from the key text information. The target user information may include but is not limited to user identity and user characteristics. Specifically, the target user information refers to "lover", "boss", "child", etc. as described above.

[0062] The corresponding application scenario information and emotional information can be determined based on the target action information and target user information. For example, if "greet" is extracted from "greet the boss" or "greet the lover", it can be determined as a greeting scene, and the target user information is "boss" or "lover", then the corresponding emotion can be determined to be solemn and respectful or warm and gentle; for example, if "goodbye" is extracted from "goodbye to the child" or "goodbye to the girlfriend", it can be determined as a farewell scene, and the target user information is "child" or "girlfriend", then the corresponding emotion can be determined to be lively and cute or romantic and gentle.

[0063] In some examples of this embodiment, the target user information may not exist in the key text information. For example, the user inputs "Celebrate birthday, project a birthday celebration light effect". At this time, the target user information cannot be obtained from the key text information. At this time, the owner information corresponding to the vehicle can be used as the target user information to provide projection services for the owner. The in-car image can also be captured by the in-car camera to obtain the age characteristics and gender attributes of the users in the car. These age characteristics and gender attributes can be used as the target user information to provide projection services for the users in the car, and then the corresponding application scenario information and emotional information can be determined based on the target action information "Celebrate birthday" and the target user information.

[0064] In some embodiments of the present application, the target instruction is an instruction input by voice, and before sub-step 212, the following sub-steps are also included:

[0065] Sub-step 311: Acquire voice feature information of the voice input containing the target instruction;

[0066] In a specific implementation, the user can also operate the vehicle projection lamp by voice input. At this time, the target command refers to the command input by the user through voice. Among them, voice feature information refers to the feature parameters extracted from the voice signal by voice recognition technology to describe and identify the voice content. These feature parameters are usually used in applications such as voice recognition, voice synthesis, and sentiment analysis to help computers understand and process voice signals.

[0067] In practical applications, speech signals can be captured to obtain original sound wave data; the original sound wave data can be preprocessed, such as denoising and framing, and the preprocessed speech data can be feature extracted to obtain speech feature information of the speech signal, such as speech rate and intonation. The speech feature information is used for further analysis and processing.

[0068] Sub-step 212 may also include the following sub-steps:

[0069] Sub-step 312: Determine application scenario information and emotion information based on target action information, target user information, and voice feature information.

[0070] In a specific implementation, the voice feature information extracted in sub-step 311 and the target action information and target user information extracted in the above steps can be input into a pre-trained model for semantic analysis and sentiment analysis to determine the corresponding application scenario information and sentiment information. In addition, if the user is inconvenient to input text, the vehicle projection light can be operated only by voice input. For example, the user inputs "greet the lover with warm lights" through the microphone of the user terminal or the microphone of the vehicle-mounted system. Then, the model can be used to perform semantic analysis on the voice information to obtain the corresponding text information "greet the lover with warm lights", and then obtain the target action information "greet" and the target user information "lover". Feature extraction is performed on the voice information to obtain the voice feature information "natural speaking speed, relaxed and happy tone", and then the corresponding application scenario information and sentiment information are determined according to the target action information, target user information and voice feature information.

[0071] In some embodiments of the present application, when the target instruction is an instruction inputted by voice, before determining the application scenario information and emotional information according to the target action information and the target user information in sub-step 312, the voice input may also be authenticated. Specifically, the voice features corresponding to the voice input information may be extracted, and the voice features include speech speed, intonation, frequency, energy, etc. These voice features are inputted into a preset vehicle owner voice matching model to obtain a voice matching score. Based on the relationship between the voice matching score and the preset matching threshold, it is determined whether the identity authentication is successful. If it is determined that the identity authentication is successful, sub-step 312 is executed again to achieve that the vehicle projection lamp can be controlled to perform projection only when the user corresponding to the voice input has the operation authority, thereby ensuring the safe operation of the vehicle.

[0072] Specifically, the voice data of common users of the vehicle can be collected in advance, and then the voice data of common users can be used to train the owner's voice matching model to obtain the owner's voice matching model of the user; wherein, the training of the owner's voice matching model can include forward propagation and back propagation. Forward propagation: input the collected voice data into the voiceprint model to obtain the matching score obtained by the voiceprint model; back propagation: compare the matching score with the reference value, and adjust the weight of the owner's voice matching model so that the matching score output by the owner's voice matching model approaches the reference value. Of course, after determining that the identity authentication is successful, the received voice data can be used to optimize the owner's voice matching model to improve the accuracy of identity authentication.

[0073] Step 103: Control the vehicle projection lights to present according to the lighting effect data.

[0074] Among them, controlling the vehicle projection light for presentation refers to displaying the generated lighting effect data on the target surface, such as the ground, wall, etc., that is, achieving a specific visual effect by controlling the parameters of the projection light (such as brightness, pattern).

[0075] In the example of this embodiment, firstly, the lighting effect data generated in step 102 is received, and these data are usually transmitted in a specific format. The received lighting effect data is parsed to extract specific operation instructions and parameters. The parsed data is mapped to specific control instructions of the vehicle projection lamp hardware. For example: the switch state is mapped to the hardware on or off instruction, the brightness value is mapped to the hardware brightness adjustment instruction, and the pattern data is mapped to the hardware pattern loading and display instructions. According to the mapped data, specific hardware control instructions are generated, such as pattern loading instructions for loading and displaying specified patterns. The generated hardware control instructions are transmitted to the control unit of the vehicle projection lamp to trigger the corresponding operation.

[0076] In some embodiments of the present application, step 103 may include the following sub-steps:

[0077] Sub-step 411: obtaining user-defined adjustment parameters for lighting effect data;

[0078] Sub-step 412: adjusting the lighting effect data according to the custom adjustment parameters to obtain adjusted lighting effect data;

[0079] Sub-step 413: Control the vehicle projection lights to present according to the adjusted lighting effect data.

[0080] In a specific implementation, the user can also adjust the generated lighting effect data. For example, the user may want the generated lighting effect to be more cheerful or brighter, or the user may want to adjust the generated color style lighting effect to black and white style or adjust the generated black and white style lighting effect to color style. At this time, the user can enter custom adjustment parameters.

[0081] After obtaining the custom adjustment parameters input by the user, these parameters can be used to adjust the generated lighting effect to obtain the adjusted lighting effect data, and then control the vehicle projection lamp to use the adjusted lighting effect data for projection. For example, for "welcome the boss, the lighting effect is solemn and majestic", the generated lighting effect is a majestic phoenix flying lighting effect, but in a high-brightness environment, a higher brightness is required to show a better effect. At this time, the user enters a custom adjustment parameter such as "brighten the lights" to adjust the brightness of the phoenix flying lighting effect and obtain a custom lighting effect that is more suitable for the current scene.

[0082] In some examples of this embodiment, the vehicle's environmental information can be collected in real time through various sensors and cameras in the vehicle-mounted system, and the generated lighting effect data can be further adjusted according to the vehicle's external environment. For example, the current ambient light can be determined through an optical sensor, and the projected light can be brightened or dimmed according to the current ambient optics; or when it is determined through a temperature sensor that the current environment is relatively cold, the projected light can be adjusted to a warm-colored light.

[0083] In some embodiments of the present application, the vehicle-mounted system can also continuously collect user feedback information on the data lighting effects generated by the vehicle projection lamp, and transmit this feedback information to the cloud for analysis and model optimization, to ensure that the trained vehicle-side lighting effect model or the cloud-based large model can continuously improve the personalized effect of the generated lighting effect data according to user preferences. The vehicle-mounted system can also establish a lighting effect parameter library, which contains lighting effect parameters corresponding to different emotional information and scene information, such as color, brightness, flashing frequency, etc. When happy, it can be red, yellow, blue and other colors flashing alternately, flashing 5 times per second; when the user is excited, the flashing frequency of the happy lighting effect is increased.

[0084] In some embodiments of the present application, step 103 may also include the following sub-steps:

[0085] Sub-step 511: collecting external image information of the vehicle;

[0086] In a specific implementation, collecting external image information of a vehicle means obtaining visual data of the vehicle's surrounding environment through a camera or other image acquisition device, and other image acquisition devices refer to optical devices used to capture images and videos. Cameras or other image acquisition devices can capture images and video data in front of the vehicle in real time.

[0087] Sub-step 512: When it is determined that the external image information includes a user outside the vehicle, determine the current position of the user outside the vehicle.

[0088] After the external image information is collected, the collected image data is transmitted to the central processing unit of the vehicle, and the image data is preprocessed, such as denoising, enhancing, correcting, etc., and then the road signs, pedestrians, other vehicles, etc. in front of the vehicle are identified by image processing technology. In the case where the external image information is identified by image processing technology and includes the user outside the vehicle, the current position of the user outside the vehicle can be determined by a variety of sensors in the vehicle, such as by collecting the footsteps or speaking sounds of the user outside the vehicle through a sound sensor, and according to the changes in the footsteps or speaking sounds. Of course, the current position of the user of the vehicle can also be determined based on the image data collected by the camera, for example, using the target detection algorithm to locate the user position in the image, combining the position information of the camera and the position of the user outside the vehicle in the image, and determining the precise position of the user outside the vehicle through geometric calculation.

[0089] Sub-step 513: Calculating the position relationship between the user outside the vehicle and the vehicle according to the current position of the user and the current position of the vehicle;

[0090] Sub-step 514: Based on the position relationship, control the vehicle projection light to use the lighting effect data for presentation.

[0091] In a specific implementation, if it is detected that the user is approaching the vehicle and falls within the projection range of the vehicle-mounted projector, the projection can be performed directly in front of the user outside the vehicle based on the relationship between the user's position and the vehicle's current position. The positional relationship between the user's position and the vehicle's position can be calculated in real time, and the position of the projected image can be changed as the positional relationship changes, further enhancing the interactivity of the welcome lighting effect.

[0092] In some examples of this embodiment, if the user stays in a certain area or suddenly changes the moving speed, the projection position will be switched in real time according to the position relationship between the user and the vehicle. Specifically, it is necessary to confirm that the projection video or projection image corresponding to the generated lighting effect data is always located in front of the user's walking trajectory. The user's feet can be identified by the sensor on the vehicle. For example, the image information of the position of the user outside the vehicle is collected by the camera, and the projection light control system is input in real time through the video stream format. The left and right feet of the user outside the vehicle are identified by the computer vision detection algorithm, and the position relationship between the left foot and the right foot relative to the center of the vehicle is obtained, and the position information of the foot closest to the vehicle is obtained, so that the presented projection video or projection image is always in front of the user. In the specific implementation, the projected lighting effect can also be reflected in the breathing effect. If the user walks faster, the frequency of the breathing effect is faster; if the user walks slower, the frequency of the breathing effect is slower. The above method is used to further enhance the vehicle user experience.

[0093] like Figure 2As shown, it is a lighting effect generation flow chart provided by some embodiments of the present application. In a specific implementation, when a user needs to control a vehicle projection lamp, in the first step, the user inputs a target instruction for the vehicle projection lamp, and the target instruction can be a text message or voice message input by the user; in the second step, a video script is generated, and a corresponding projection video script is determined according to the obtained text information or voice information; in the third step, the video is refined, and specifically, the video script can be further refined according to the generated text, such as scene division, target person identity determination, setting dialogue, etc.; in the fourth step, after the video is refined, the corresponding music, video, and human voice are obtained. For example, when celebrating a birthday, the birthday image of the other party is projected and accompanied by birthday music and birthday voices; in the fifth step, the generated music, video, and human voice are synthesized, and the synthesized lighting effect is projected, and the generated audio is synchronously played through the audio playback system.

[0094] The embodiment of the present application obtains a target instruction input by a user, and when the target instruction indicates to control the vehicle projection light, determines key text information in the target instruction, generates lighting effect data for the vehicle projection light according to the key text information, matches the lighting effect data with the key text information, and controls the vehicle projection light for presentation according to the lighting effect data. Different vehicle projection effects are generated according to different input information, so that the lighting effect of the vehicle projection light is more in line with the user's personalized needs, thereby enhancing the interactivity between the vehicle and the user.

Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.
