[0028] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] In related technologies, vehicles can only obtain surrounding environment information and perform corresponding projection to prompt pedestrians or users, but lack some entertainment and practical functions regarding headlights and human-computer interaction.

[0030] In order to solve the problem in the related art that vehicles lack some entertainment and practical functions regarding headlights and human-computer interaction, the present application provides a technical concept: by obtaining the user's description information of the projection object, further obtaining the data to be projected, thereby controlling the vehicle's headlights to project the data to be projected, so as to project the information the user wants to project, and increase the practicality or entertainment of human-computer interaction through intelligent headlights.

[0031] The projection method of the present application will be described in detail below.

[0032] Figure 1 This is a system block diagram of an application scenario of a projection method shown in an embodiment of the present application. Figure 1 As shown, it includes a vehicle controller, an information input component, an information output component and a projection system, wherein the projection method is applied to the vehicle controller, the information input component, the information output component and the projection system are respectively communicated with the vehicle controller, and the projection system includes the vehicle's headlights.

[0033] Before obtaining the user's description of the projection object collected by the vehicle's information input component, it is necessary to first turn on the vehicle's projection system. The specific method for turning on the vehicle's projection system is as follows:

[0034] Acquiring user wake-up information of the projection system collected by the information input component of the vehicle;

[0035] According to the wake-up information, the projection system of the vehicle is controlled to enter a start state.

[0036] In this embodiment, the wake-up information is used to wake up the vehicle's projection system. The vehicle's information input component can collect the user's wake-up information and then control the vehicle's projection system to be turned on based on the wake-up information. Specifically, the wake-up information can be gesture wake-up information or voice wake-up information. The information input component can be a built-in camera or a microphone in the vehicle. The built-in camera is used to collect the user's gesture wake-up information, and the microphone is used to collect the user's voice wake-up information.

[0037] For example, the user can make the corresponding gesture to wake up the projection system within the information collection range of the built-in camera: a victory gesture. The built-in camera will transmit the collected gesture wake-up information to the vehicle controller, and the vehicle controller will control the projection system to turn on according to the gesture wake-up information. Alternatively, the user can say the voice "turn on projection" to wake up the projection system in the vehicle. After the microphone collects the voice wake-up information, it will transmit the voice wake-up information to the vehicle controller, and the vehicle controller will control the projection system to turn on according to the voice wake-up information.

[0038] Through the above method, the projection system can be turned on through gestures or voice.

[0039] Figure 2 This is a flowchart of a projection method according to an embodiment of the present application. Figure 2 As shown, the projection method includes:

[0040] Step S201: while the projection system of the vehicle is in an on-state, obtaining description information of the projection object by the user collected by the information input component of the vehicle.

[0041] In this embodiment, after the vehicle's projection system is turned on, the user's projection information can be obtained for corresponding projection. Specifically, the user's description information of the projection object can be collected through the information input component, wherein the projection object can be used to prompt surrounding vehicles or pedestrians, and can also be used for user entertainment interaction. For example, the projection object can be a turn sign for prompting surrounding vehicles or pedestrians, or it can be an animated character or animated video, etc., for user entertainment interaction.

[0042] Step S202: obtaining data to be projected according to the description information of the projection object.

[0043] In this embodiment, the data to be projected may be retrieved from the database according to the description information of the projection object.

[0044] In a feasible implementation, the description information includes at least: a user's voice description of the projection object; and obtaining the data to be projected according to the description information of the projection object includes:

[0045] Recognizing the description voice of the projection object to obtain a description text of the projection object;

[0046] Searching a database according to keywords corresponding to the description text to obtain a first search result, wherein the database stores multiple groups of keywords and their corresponding data to be projected;

[0047] When the first search result is not empty, obtaining at least one piece of data to be projected from the first search result;

[0048] When the first search result is empty, the preset data to be projected is obtained.

[0049] In this embodiment, the description information may be the user's descriptive voice of the projection object. The descriptive voice is collected by the microphone in the information input component and transmitted to the vehicle controller. The vehicle controller obtains the descriptive voice of the projection object, performs voice recognition on the descriptive voice, and obtains a description text of the projection object. Then, based on the description text, the corresponding data to be projected is retrieved. Specifically, based on the keywords corresponding to the description text, the database is searched, wherein the database may be a local database pre-established by the vehicle or a third-party database. The database pre-stores multiple groups of keywords and the data to be projected corresponding to each group of keywords. The first search result can be retrieved from the database using the keywords corresponding to the description text, wherein the first search result may be empty or not empty. If the data to be projected corresponding to the keywords corresponding to the description text can be retrieved from the database, the first search result is not empty. If the data to be projected corresponding to the keywords corresponding to the description text cannot be retrieved from the database, the first search result is empty.

[0050] When the first search result is not empty, that is, the first search result contains at least one piece of data to be projected, at least one piece of data to be projected can be directly obtained from the first search result for projection. Specifically, one piece of data to be projected can be obtained so that the vehicle controller controls the headlights to project the one piece of data to be projected. Alternatively, a preset number of data to be projected can be obtained from the first search result, and the vehicle controller controls the headlights to project a preset number of multiple pieces of data to be projected in turn.

[0051] When the first search result is empty, that is, there is no data to be projected in the first search result, the preset data to be projected is directly obtained. The preset data to be projected can be stored in a database. The preset data to be projected can be a preset picture or preset text.

[0052] Figure 3This is a schematic diagram of a projection result when no result corresponding to the description of the voice is retrieved, as shown in an embodiment of the present application. For example, the user can directly say the name of the object to be projected in the vehicle, such as "chicken leg". When the microphone collects the voice information of "chicken leg", it transmits it to the vehicle controller. The vehicle controller recognizes the voice information and obtains the corresponding text information "chicken leg". The vehicle controller searches the local database or calls a third-party database based on the keyword "chicken leg" to obtain the first search result. If multiple data are retrieved, 3 of them are randomly selected as the data to be projected, and then the vehicle lights are controlled to project the 3 data in turn. If no data is retrieved, the preset text "What you said is so profound, it is beyond my understanding" is obtained, and then the vehicle lights are controlled to project the preset text, such as Figure 3 shown.

[0053] Through the above method, when the user's description information is a descriptive voice, the corresponding text information can be identified and generated according to the user's descriptive voice, and the data to be projected can be retrieved from the database according to the corresponding keywords of the text information to realize the voice projection function of the vehicle.

[0054] In a feasible implementation, when the first search result is empty, feedback data matching the keywords corresponding to the description text is obtained from the material library;

[0055] Updating the feedback data and its corresponding keywords into the database;

[0056] When it is detected again that the projection system of the vehicle enters the on state, controlling the headlights of the vehicle to project the feedback data and the first prompt text associated with the description text; or

[0057] When it is detected again that the projection system of the vehicle enters the on state, the vehicle lights are controlled to project the feedback data, and the first prompt text associated with the description text is displayed through the information output component of the vehicle.

[0058] In this embodiment, when the first search result is empty, the feedback mode can be turned on to feed back the database. Specifically, when the first search result is empty, feedback data that matches the keywords corresponding to the description text is obtained from the material library, where the material library is one or more other third-party information libraries different from the currently searched database, and then the obtained feedback data is updated to the database.

[0059] For example, during the feedback process, the vehicle controller searches for corresponding images in various material libraries based on the text information corresponding to the unrecognizable voice, and then stores the text information and images in combination. The system administrator manually reviews the above information regularly and updates the status of the combination after the review. When the status of the combination is updated to "feedback successful", the combination is updated to the database so that the text information can be used when it is projected again.

[0060] Figure 4 This is a schematic diagram of a feedback projection result shown in an embodiment of the present application. When the projection system of the vehicle is detected to be turned on again, the vehicle's headlights can be controlled to project the feedback data and the first prompt text associated with the description text. The first prompt text associated with the description text is a prompt text generated based on the description text. For example, if the description text is "chicken leg", the first prompt text can be "The content you wanted to project last time was 'chicken leg'. I found the answer. Please enjoy it." Figure 4 shown.

[0061] Or, when the vehicle's projection system is detected to be on again, the vehicle's lights are controlled to project the feedback data, and the first prompt text associated with the description text is displayed through the vehicle's information output component. The information output component can be a display panel or a microphone. The first prompt text associated with the description text is displayed through the vehicle's information output component. Specifically, the first prompt text can be output through the display panel, or the voice information corresponding to the first prompt text can be output through the microphone.

[0062] Through this method, if the first search result is empty, feedback data matching the keywords corresponding to the description text can be obtained from the material library, and the database can be updated so that the next time the same description text is encountered, the data to be projected can be retrieved. In addition, when the vehicle is next turned on, the data to be projected corresponding to the last time the user attempted to project but failed can be displayed to the user in a timely manner.

[0063] In a feasible implementation manner, the description information further includes: a gesture made by the user with respect to the projection object; and obtaining the data to be projected according to the description information of the projection object includes:

[0064] Recognizing the gesture and generating a description picture of the projection object;

[0065] Searching the image library according to the described image to obtain a second search result;

[0066] If the second search result is not empty, obtaining at least one image to be projected from the second search result;

[0067] When the second search result is empty, a preset picture to be projected is obtained.

[0068] In this embodiment, the descriptive information may be a gesture made by the user toward the projection object. The gesture is captured by a camera in the information input component and transmitted to the vehicle controller. The camera captures the gesture using the principle of 3D structured light imaging, and the gesture is recognizable within a specified area. The vehicle controller obtains the gesture of the projection object and recognizes the gesture to obtain a corresponding descriptive image. Then, based on the descriptive image, the corresponding data to be projected is retrieved. Specifically, based on the descriptive image, a similarity comparison is performed with images in the database, and images with a similarity greater than a preset value are determined as second search results. The database contains multiple images, and the second search result may or may not be empty. If an image with a similarity greater than the preset value to the image can be retrieved from the database, the second search result is not empty. If an image with a similarity greater than the preset value to the image cannot be retrieved from the database, the second search result is empty.

[0069] When the second search result is not empty, that is, the second search result contains at least one picture, at least one picture can be directly obtained from the second search result for projection. Specifically, one picture can be obtained so that the vehicle controller controls the headlights to project the obtained picture. Alternatively, a preset number of pictures can be obtained from the second search result, and the vehicle controller controls the headlights to project a preset number of pictures in turn.

[0070] When the second search result is empty, that is, there is no picture in the second search result, the preset picture to be projected is directly obtained. The preset picture to be projected can be stored in the database. Specifically, one or more pictures can be regularly obtained as the preset pictures to be projected.

[0071] Figure 5 This is a schematic diagram of a projection result when no result corresponding to a gesture is retrieved, as shown in an embodiment of the present application. For example, after the gesture is recognized, it is saved in the form of a description picture. The vehicle controller can perform a similarity comparison based on the local database or call a third-party picture library, and select the picture to be projected according to the algorithm. Specifically, a picture with a similarity greater than a preset value or a picture with the highest similarity can be selected. When there are multiple pictures with a similarity greater than a preset value or a picture with the highest similarity, one or more pictures are randomly selected; when no picture is matched, one or more specific pictures (for example: aliens) are obtained as data to be projected, and text information can also be obtained at the same time: "Oops, it cannot be recognized", so that the data to be projected (alien) and text information can be output through the car lights, such as Figure 5 The method for obtaining and using the above-mentioned specific images is as follows: the vehicle controller periodically (which can be set to 1 month) retrieves 10 alien images from a third-party image library and stores them. During the current time period, the specific projection image is randomly obtained from these 10 images.

[0072] Through the above method, when the user's description information is a gesture, a description picture can be identified and generated according to the user's gesture, and the data to be projected can be retrieved from the database according to the description picture to realize the gesture projection function of the vehicle.

[0073] In a feasible implementation, when the second search result is empty, a feedback picture having a similarity with the description picture greater than a preset similarity is obtained from the material library;

[0074] Updating the feedback picture to the picture library;

[0075] When it is detected again that the projection system of the vehicle is in the on state, controlling the headlights of the vehicle to project the feedback picture and the second prompt text associated with the description picture; or

[0076] When it is detected again that the projection system of the vehicle has entered the on state, the vehicle lights are controlled to project the feedback picture, and the second prompt text associated with the description picture is displayed through the information output component of the vehicle.

[0077] In this embodiment, when the second search result is empty, the feedback mode can be turned on to feed back the database. Specifically, when the second search result is empty, feedback data corresponding to the description picture is obtained from the material library, where the material library is one or more other third-party information libraries different from the currently searched database, and then the obtained feedback data is updated to the database.

[0078] When the vehicle's projection system is detected to be turned on again, the vehicle's headlights can be controlled to project the feedback picture and the second prompt text associated with the description picture, wherein the second prompt text associated with the description picture is a prompt text generated based on the description picture. For example, if the description picture is a "heart" picture, the second prompt text can be "The content you wanted to project last time was 'heart'. I found the answer, please enjoy it."

[0079] Or, when the vehicle's projection system is detected to be on again, the vehicle's lights are controlled to project the feedback picture, and the second prompt text associated with the description picture is displayed through the vehicle's information output component. The information output component can be a display panel or a microphone. The second prompt text associated with the description picture is displayed through the vehicle's information output component. Specifically, the second prompt text can be output through the display panel, or the voice information corresponding to the second prompt text can be output through the microphone.

[0080] Through the above method, if the second search result is empty, the feedback data corresponding to the description image can be obtained from the material library and the database can be updated so that the next time the same description image is encountered, the data to be projected can be retrieved. In addition, when the vehicle is next turned on, the data to be projected corresponding to the last time the user attempted to project but failed can be displayed to the user in a timely manner.

[0081] Step S203: controlling the vehicle lights to project the data to be projected.

[0082] In this embodiment, after obtaining the data to be projected, the vehicle controller can control the vehicle's lights to project the data to be projected. The lights here can specifically be the vehicle's headlights. Specifically, when the description information is a description of voice or gesture, any one of the two headlights of the vehicle can be controlled to project the data to be projected.

[0083] When the descriptive information is a description of voice and gestures, one of the headlights can be controlled to project the data to be projected corresponding to the description of voice and gestures, that is, the left headlight or the right headlight can be controlled to project the data to be projected corresponding to the description of voice and gestures. Specifically, the left headlight can be controlled to first project the data to be projected corresponding to the description of voice, and then the left headlight can be controlled to project the data to be projected corresponding to the gestures. Alternatively, the left headlight can be controlled to first project the data to be projected corresponding to the gestures, and then the left headlight can be controlled to project the data to be projected corresponding to the description of voice.

[0084] When the descriptive information is a description of voice and gestures, the left headlight and the right headlight can be used respectively to project the data to be projected corresponding to the description of voice and gestures, that is, the left headlight can be controlled to project the data to be projected corresponding to the description of voice, and the right headlight can be controlled to project the data to be projected corresponding to the gesture; or, the right headlight can be controlled to project the data to be projected corresponding to the description of voice, and the left headlight can be controlled to project the data to be projected corresponding to the gesture.

[0085] The specific method for controlling the vehicle's headlights to project the data to be projected is: the vehicle controller transmits the data to be projected to the pixel matrix driver module of the projection system, and the pixel matrix driver module drives the LED pixel matrix of the headlights according to the instructions of the vehicle controller to realize the display of graphics or animations.

[0086] The projection method provided by an embodiment of the present invention is that when the projection system of a vehicle is in an on-state, the information input component can collect the user's description information of the projection object. At this time, the vehicle controller can obtain the description information of the projection object and process the description information of the projection object to obtain the data to be projected corresponding to the description information of the projection object. Finally, the vehicle controller controls the vehicle's headlights to project the data to be projected. Through the above method, information can be obtained from the user, and the data to be projected corresponding to the user's description information of the projection object can be projected through the headlights, thereby increasing the entertainment and practical functions of the vehicle's headlights and human-computer interaction.

[0087] In a feasible implementation manner, before step S203, the method further includes:

[0088] Obtaining the collection time of the description information;

[0089] The projection background color is determined according to the acquisition time of the description information.

[0090] The step S203 specifically includes:

[0091] The headlights of the vehicle are controlled to perform projection according to the projection background color and the data to be projected.

[0092] In this embodiment, the projection background color is determined by obtaining the acquisition time of the description information, so that different projection background colors can be determined according to different acquisition times, so as to improve the projection effect.

[0093] Specifically, the projection background color can be divided into day mode and night mode. 06:00-18:00 is defined as day mode, and the rest of the time is defined as night mode. In day mode, the projection background color can be fluorescent purple, and in night mode, the projection background color can be fluorescent green. Specifically, when controlling the vehicle lights to project data based on the projection background color and the data to be projected, the data to be projected is placed on the projection background color.

[0094] In a feasible embodiment, the method further includes:

[0095] When detecting that the projection system of the vehicle enters an on state, starting timing;

[0096] If the description information is not obtained within the first preset time period, generating prompt information and displaying the prompt information through the information output component of the vehicle;

[0097] If no description information is obtained within a second preset time period, controlling the projection system of the vehicle to enter a shutdown state;

[0098] If the description information is obtained within the second preset time period, the timing is restarted.

[0099] In this embodiment, when the vehicle's projection system is detected as being in the on state, a timer begins. If no description information is obtained within a first preset time period, the projection system is determined to be in a silent state. At this point, a prompt message is generated and displayed via the vehicle's information output component to alert the user. Specifically, the first preset time period may range from 10 to 15 minutes, and the prompt message may read, "Master, I haven't detected your instructions for a long time. Do you want to turn off the projection function?" If no description information is obtained within a second preset time period, the vehicle's projection system is controlled to be turned off. The second preset time period may range from 12 to 17 minutes. Displaying the prompt message via the vehicle's information output component may specifically include outputting the prompt message via text or voice output via the vehicle's information output component. If a voice message or gesture message indicating the projection system is turned off is obtained within the second preset time period, the projection system is also controlled to be turned off. If a description message is obtained within the second preset time period, the timer restarts. Alternatively, if a voice message or gesture message indicating the projection system is resumed is obtained within the second preset time period, the timer restarts. By using the above method, the projection system can be automatically shut down to avoid excessive consumption of the projection system.
