[0052] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] With the continuous development of the vehicle industry, the configuration of the vehicle interior is also becoming more diversified. The existing central control screen can not only provide users with audio and video, navigation and other consultation, but also show users the three-dimensional car model of the vehicle. Users can know the current status of the vehicle body based on the displayed three-dimensional car model, such as the opening and closing status of the windows, doors, hood, trunk, etc. Of course, the three-dimensional car model can also be displayed in the APP (Application) of the mobile terminal. When the user leaves the vehicle, he can also know the current status of the vehicle body based on the three-dimensional car model in the APP.

[0054] In the prior art, the three-dimensional car model displayed on the central control screen or in the APP only has the basic frame of the vehicle, so that when the user views the three-dimensional car model, he can only feel the function of the three-dimensional car model, but cannot have a sense of connection between the three-dimensional car model and the vehicle itself.

[0055] Therefore, in an embodiment of the present invention, when generating a three-dimensional car model, the license plate information of the own vehicle is added to the three-dimensional car model, so that when the user views the three-dimensional car model, he can have a sense of association between the three-dimensional car model and his own vehicle.

[0056] Reference Figure 1 , shows a flow chart of steps of an embodiment of a method for generating a three-dimensional vehicle model of the present invention, the method can be applied to a vehicle, and specifically may include the following steps:

[0057] Step 102: Obtain the license plate information corresponding to the vehicle.

[0058] In order to generate a three-dimensional vehicle model with license plate information, the license plate information corresponding to the user's vehicle can be obtained first; the license plate information can be obtained from the cloud server by the central control system of the vehicle. The license plate information can be automatically entered and saved in the cloud server when the vehicle registration procedure is carried out for the vehicle, and the embodiment of the present invention does not limit this.

[0059] Step 104: Determine a corresponding license plate texture map based on the license plate information.

[0060] Texture mapping, also known as texture, is one or more two-dimensional graphics that represent the surface of an object. Drawing texture mapping is a common rendering method in computer graphics systems. When the texture is mapped to the surface of an object in a specific way, the object can look more realistic. When understanding texture mapping, you can think of texture as the pixel color applied to the surface of an object. In the real world, texture can represent the color, pattern, and tactile characteristics of an object, but in computer graphics processing, texture only represents the pattern on the surface of an object, and it cannot change the geometric form of the object. Furthermore, it is just a high-intensity calculation behavior.

[0061] In an embodiment of the present application, after the license plate information corresponding to the vehicle is obtained, the corresponding license plate texture map can be determined based on the license plate information.

[0062] As an example, a corresponding license plate texture map library may be generated in advance for the license plate. When the license plate texture map corresponding to the license plate information needs to be determined, it may be obtained from the license plate texture map library based on the license plate information.

[0063] Since the license plate includes the background of the license plate and the characters thereon, the license plate texture map library may be pre-generated for various license plate backgrounds and characters that may constitute the license plate.

[0064] Step 106: Generate a 3D vehicle model with the license plate information based on the license plate texture map.

[0065] After determining the license plate texture map, the license plate texture map can be added to a pre-made 3D vehicle model, thereby generating a 3D vehicle model with the license plate information; the pre-made 3D vehicle model can be generated by model-making software for the vehicle, for example: 3D Studio Max, etc., and the embodiments of the present invention do not limit this.

[0066] After the model-making software generates the pre-made 3D vehicle model, it can be input into the vehicle's central control system; when the central control system receives the license plate information, it can determine the license plate texture map based on the license plate information, and generate a 3D vehicle model with the license plate information based on the license plate texture map and the pre-made 3D vehicle model.

[0067] In summary, in the embodiments of the present invention, first obtain the license plate information corresponding to the vehicle; then determine the corresponding license plate texture map based on the license plate information; and then generate a 3D vehicle model with the license plate information based on the license plate texture map. By generating a 3D vehicle model with the license plate information, when the user views and uses the related functions of the 3D vehicle model, a sense of association can be generated between the 3D vehicle model and the vehicle itself, improving the user experience.

[0068] Refer to Figure 2 , which shows the step flow chart of an alternative embodiment of the method for generating a 3D vehicle model of the present invention. The method can be applied to a vehicle and specifically may include the following steps:

[0069] Step 202: Obtain the license plate information corresponding to the vehicle.

[0070] This step 202 is similar to the above step 102 and will not be elaborated here.

[0071] Step 204: Determine the license plate number and license plate type based on the license plate information.

[0072] A license plate is composed of multiple characters on the license plate and the background of the license plate. The multiple characters on the license plate can form the license plate number of the license plate, such as "Hu A******". And the background of the license plate corresponds to different colors according to different license plate types. For example, the background of a new energy type license plate is green.

[0073] Therefore, in order to make the license plate in the generated 3D vehicle model with the license plate information consistent with the license plate of the vehicle itself, the license plate number and license plate type can be determined first according to the license plate information to determine the multiple characters on the license plate and the color of the background of the license plate.

[0074] Step 206: Determine the target license plate background texture map corresponding to the license plate type from the pre-set correspondence between license plate types and license plate background texture maps.

[0075] In an embodiment of the present invention, the license plate texture map includes a target license plate background texture map and a plurality of target character texture maps.

[0076] After determining the license plate number and license plate type corresponding to the license plate information of the vehicle, a plurality of target character texture maps can be determined according to the license plate number, and the target license plate background texture map can be determined according to the license plate type.

[0077] As an example, license plate background texture maps of multiple different license plate types can be determined in advance. For example: License plates of multiple different license plate types can be photographed first, then the characters on them can be removed, only the blank license plates are left, and then the blank license plates are rendered into texture objects, and then the corresponding license plate background texture maps are generated according to the texture objects.

[0078] As an example, Canvas2D can be used to perform Off-Screen drawing on the blank license plate to obtain a texture object, and then the corresponding license plate background texture map is generated according to the obtained texture pair.

[0079] After obtaining the corresponding license plate background texture maps according to license plates of multiple different types, the correspondence between license plate types and license plate texture maps can be established.

[0080] When it is necessary to determine the license plate background texture map of the vehicle, the license plate texture map corresponding to the license plate type of the vehicle can be determined by looking up the correspondence between the license plate type and the license plate texture map, and it is used as the target license plate texture map.

[0081] Step 208: Analyze the license plate number to obtain a plurality of single characters.

[0082] Step 210: Determine the target character texture map corresponding to each single character from the pre-set correspondence between characters and character texture maps.

[0083] The license plate number is composed of geographical location identifiers, numbers, and letters. Therefore, logical analysis can be performed on the license plate number first to obtain a plurality of single characters. For example: If the license plate number is "沪A12345B", the first part of the license plate can be parsed into the geographical location identifier "沪" and "A", and the second part of the license plate can be parsed into the numbers and letters "1", "2", "3", "4", "5", "B", so as to obtain eight single characters: "沪", "A", "1", "2", "3", "4", "5", and "B".

[0084] After multiple single characters are parsed, the corresponding target character texture maps for each single character can be determined respectively by looking up the corresponding relationship between the preset characters and the character texture maps.

[0085] As an example, the character texture maps in the corresponding relationship between the preset characters and the character texture maps can be generated in the following way:

[0086] First, determine the characters corresponding to the geographical location identifiers. For example, Beijing corresponds to "Jing", Guangdong corresponds to "Yue", Hunan corresponds to "Xiang", etc.

[0087] Then, render the characters corresponding to the geographical location identifiers into map objects respectively, and then generate the corresponding character texture maps according to the map objects.

[0088] The numbers in the license plate number can include integers from 0 to 9, and the letters can include A - Z. Therefore, the numbers 0 - 9 and the letters A - Z can also be rendered into map objects respectively, and then the corresponding character texture maps are generated according to the map objects.

[0089] After generating the character texture maps corresponding to the characters of the geographical location identifiers, as well as the character texture maps corresponding to 0 - 9 and A - Z, the corresponding relationship between the characters and the character texture maps can be established, so that when it is necessary to determine the character texture maps corresponding to multiple single characters of the license plate number, the corresponding multiple target character texture maps can be determined by looking up the corresponding relationship between the characters and the character texture maps.

[0090] Step 212: Obtain the pre - made three - dimensional vehicle model corresponding to the vehicle, and the three - dimensional vehicle model includes a license plate bottom frame.

[0091] Since the running memory required by three - dimensional model - making software is relatively large, and if a model - making software is embedded in the vehicle's central control information, additional software that can be applied to the vehicle's central control system needs to be developed. Therefore, in order to reduce the investment in development resources, the three - dimensional model of the vehicle can be generated in the model - making software in the computer according to the actual parameters of the vehicle in advance, and the three - dimensional model includes a license plate bottom frame for adding license plate information.

[0092] As an example, the license plate bottom frame includes a front license plate bottom frame and a rear license plate bottom frame.

[0093] A real vehicle has a license plate at the front and rear of the vehicle head respectively. Therefore, in order to establish a more realistic sense of association between the three - dimensional vehicle model and the vehicle itself, when making the three - dimensional vehicle model in advance, a license plate bottom frame can be made at both the front and rear of the vehicle head.

[0094] Step 214: Add a display object on the license plate bottom frame, and assign the target license plate background texture map to the display object.

[0095] After obtaining the pre-made three-dimensional car model, a display object can be added to the license plate bottom frame, and then the target license plate background texture map corresponding to the license plate information can be assigned to the display object, so that the background color of the license plate bottom frame in the three-dimensional car model is consistent with the background color of the real license plate of the vehicle.

[0096] As an example, display objects may be added to the front license plate bottom frame and the rear license plate bottom frame respectively, and the target license plate background texture map may be assigned to the display objects added to the front and rear license plate bottom frames respectively.

[0097] Step 216: Add multiple sub-objects on the license plate bottom frame, and assign the multiple target character texture maps to the multiple sub-objects.

[0098] After assigning the target license plate background texture map to the display object, multiple sub-objects can be added to the license plate bottom frame, for example, 8 sub-objects can be added to the license plate bottom frame, and each sub-object can add a single character.

[0099] After adding multiple sub-objects to the license plate bottom frame, multiple target character texture maps determined in advance can be assigned to the multiple sub-objects respectively.

[0100] Since the multiple single characters of the license plate number have a certain order, when assigning the multiple target character texture maps to the multiple sub-objects, the following steps may also be included:

[0101] Determining the order of the plurality of target character texture maps according to the license plate information;

[0102] The target character texture maps are assigned to the sub-objects according to the order of the target character texture maps.

[0103] First, the order of the multiple single characters determined in advance is determined according to the license plate information, and then the order of the target character texture maps corresponding to the multiple single characters is determined according to the order of the multiple single characters; then, according to the order, the target character texture maps are assigned to the sub-objects in turn, ensuring that the order of the license plate numbers in the generated three-dimensional car model with license plate information is consistent with the order of the real license plate numbers of the vehicle, giving users a more realistic usage experience.

[0104] In one embodiment of the present invention, when assigning the plurality of target character texture maps to the plurality of sub-objects, the following steps may also be included:

[0105] Adjusting the multiple target character texture maps to be consistent with the size of the multiple sub-objects;

[0106] The resized target character texture maps are assigned to the plurality of sub-objects.

[0107] In order to ensure that the target character texture map will not exceed the boundary of the sub-object and affect the user experience after being assigned to the sub-object, the size of the sub-object can be obtained, and based on the size of the sub-object, the target character texture map can be adjusted to be consistent with the size of the sub-object; then the adjusted target character texture map is assigned to the sub-object to generate a three-dimensional car model with license plate information.

[0108] In summary, in the embodiment of the present invention, a three-dimensional car model with license plate information is generated by generating a license plate background texture map and a license plate number character texture map, so that the generated three-dimensional car model has a stronger sense of association with the vehicle itself, further improving the user experience.

[0109] In addition, a three-dimensional vehicle model with license plate information is generated based on the order and size of the license plate numbers, ensuring the consistency between the license plate in the three-dimensional vehicle model and the license plate of the vehicle.
