[0002] Existing lighting effect displays are divided into two types: lighting effect display chip preset mode and real-time image transmission. The preset mode means that the specified lighting effect is saved in the lighting effect library of the lighting effect controller. When the user sends the lighting mode number to the lighting effect controller, the lighting effect controller controls the vehicle's lights to display the specified lighting effect according to the specified lighting effect in the lighting effect library, but custom control cannot be achieved in this case. Real-time image transmission means that the custom lighting effect image is transmitted to the lighting effect controller in real time through the host, and the lighting effect controller controls the vehicle's lights to display the custom lighting effect image. However, in the process of displaying the custom lighting effect image, due to the large amount of data of the custom image, the real-time transmission of the custom image to the lighting effect controller through the host requires a large amount of communication resources, which is prone to communication congestion and delays.

[0071] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0072] Reference Figure 1 , Figure 1 The figure is a schematic diagram of the device structure of the hardware operating environment involved in the embodiment of the present invention.

[0073] like Figure 1 As shown, the device may include: a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a button, and the user interface 1003 may optionally include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a Wi-Fi interface). The memory 1005 may be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory. The memory 1005 may optionally be a storage device independent of the aforementioned processor 1001.

[0074] Those skilled in the art will understand that Figure 1 The structure of the lighting effect display device shown in the figure does not constitute a limitation on the lighting effect display device, and may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

[0075] like Figure 1As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a lighting effect display program.

[0076] exist Figure 1 In the lighting effect display device shown, the network interface 1004 is mainly used to connect to the server and communicate data with the server; the user interface 1003 is mainly used to connect to the user terminal and communicate data with the terminal; the lighting effect display device of the present invention calls the lighting effect display program stored in the memory 1005 through the processor 1001, and executes the lighting effect display method provided by the embodiment of the present invention.

[0077] Based on the above hardware structure, an embodiment of a lighting effect display method of the present invention is proposed.

[0078] Reference Figure 2 , Figure 2 FIG. 4 is a flow chart of a first embodiment of a lighting effect display method according to the present invention.

[0079] In a first embodiment, the lighting effect display method comprises the following steps:

[0080] Step S10, obtaining lighting effect information to be displayed, and sending the lighting effect information to be displayed to the vehicle body controller.

[0081] It should be noted that the executor of this embodiment is a vehicle, and a lighting effect display program is provided on the vehicle. Customized lighting effect display can be performed according to the lighting effect display program. The vehicle includes a host IVI, a body controller CCM and a light controller. The host includes an encoder, and the light controller includes a decoder. The lighting effect sample is encoded by the encoder in the host to obtain compressed and packaged lighting effect data, and the encoded lighting effect data is decoded by the decoder in the light controller to obtain target lighting effect data, thereby realizing customized lighting effect display through the encoded lightweight lighting effect data.

[0082] In this embodiment, the encoded lighting effect data is still displayed in a static or dynamic image. When the lighting effect is started, the lighting effect information to be displayed, that is, the customized lighting effect data selected by the user, is obtained, and the corresponding encoded lighting effect label information is obtained according to the lighting effect data selected by the user. The lighting effect label information can be identified in the form of an ID, and can also be identified by other forms of labels. This embodiment is not limited to this, and the ID is used as the label information as an example for explanation. When obtaining the lighting effect information to be displayed selected by the user, the lighting effect ID is obtained according to the lighting effect information to be displayed. Since the encoded lighting effect data is cached through the lighting effect library in the body controller, the lighting effect information to be displayed is sent to the body controller, and the lighting effect data is read by the body controller. The lighting effect database can also be stored in the cloud, and the corresponding lighting effect data can be found through the lighting effect library in the cloud.

[0083] In a specific implementation, the lighting effect data is obtained by encapsulating through the encoder in the host, including: obtaining a lighting effect sample; determining the image type of the lighting effect sample, and extracting a foreground image and a background image in the lighting effect sample; obtaining a foreground attribute and foreground data according to the foreground image, and obtaining a background attribute according to the background image; encapsulating according to the tag information, the image type, the background attribute, the foreground attribute and the foreground data to obtain the lighting effect data, such as Figure 3 The schematic diagram of the packaging format of lighting effect data is shown, wherein the image type indicates whether the lighting effect sample belongs to a static image or a dynamic image. When the lighting effect sample belongs to a static image, the static position is 1, and when the lighting effect sample belongs to a dynamic image, the dynamic position is 1. Background attributes include background height, background width, and background color, etc., foreground attributes include foreground height, foreground width, foreground center coordinates, etc., and the tag information can be a tag ID or other forms of tagging. This embodiment does not limit this. The lighting effect data is packaged by setting the tag ID, static or dynamic position, background height, background width, background color, foreground height, foreground width, foreground center coordinates and foreground data. Due to the new data packaging format, the background and foreground are separated, thereby achieving the purpose of reducing the amount of information.

[0084] It is understandable that the creation of lighting effects is separated from the calling of lighting effects. When creating lighting effects, the lighting effects are stored on the CCM (on-board computer), and the IVI (in-vehicle entertainment system) uses the lighting effect ID to call them, reducing the communication volume. The created lighting effects are dynamically cached in the lighting controller, and the loaded lighting effects can be called by ID during the power-on process.

[0085] Step S20, extracting the label information of the lighting effect information to be displayed through the body controller, and obtaining lighting effect data from a preset database according to the label information, and sending the lighting effect data to the light controller, wherein the lighting effect data is compressed and packaged by the encoder in the host.

[0086] In this embodiment, the preset database includes the local database and the cloud database of the CCM. In order to determine whether to obtain the lighting effect data from the local data or from the cloud database, the lighting effect source information can be determined according to the lighting effect information to be displayed. When the lighting effect source information is local, the lighting effect data is obtained from the local database according to the tag information. When the lighting effect source information is cloud, the lighting effect data is searched from the cloud database according to the tag information and downloaded. Figure 4The overall process diagram of calling lighting effects is shown. After enabling the lighting effect, enable the lighting effect ID, determine the source of the lighting effect, and when the lighting effect source is local, read the lighting effect data from the CCM database. When the lighting effect source is cloud, download the lighting effect from the CCM cloud database and archive it locally. The lighting effect downloaded from the cloud can also be saved in the CCM local database, and then read the lighting effect data from the CCM local database, thereby obtaining the lighting effect data from the database.

[0087] Step S30, decoding the lighting effect data through a decoder in the lighting controller to obtain target lighting effect data, and controlling the vehicle lights to display the lighting effect according to the target lighting effect data.

[0088] It should be noted that since the host cannot communicate directly with the light controller, the lighting effect can be set in the body controller, and the body controller is used as a transfer station between the host and the light controller. The host sends the encoded, compressed and encapsulated lighting effect data to the body controller through Ethernet communication for storage, thereby reducing the occupation of communication resources by transmitting the compressed and encapsulated lightweight data. The body controller and the light controller are connected through the CAN bus, and the body controller transmits the lighting effect data to the light controller through the CAN bus, thereby realizing the display of the lighting effect.

[0089] In this embodiment, the lighting effect information to be displayed is obtained, and the lighting effect information to be displayed is sent to the body controller; the tag information of the lighting effect information to be displayed is extracted by the body controller, and the lighting effect data is obtained from a preset database according to the tag information, and the lighting effect data is sent to the light controller, wherein the lighting effect data is compressed and packaged by the encoder in the host; the lighting effect data is decoded by the decoder in the light controller to obtain target lighting effect data, and the vehicle lights are controlled to display the lighting effects according to the target lighting effect data, so that when performing a customized lighting effect display, only the encoded lighting effect data needs to be sent to the light controller for displaying the lighting effect, and since the amount of data of the encoded lighting effect data is small, lightweight data transmission is achieved, and the data transmission amount and CAN bus load are reduced.

[0090] Reference Figure 5 , Figure 5 The flowchart of the second embodiment of the lighting effect display method of the present invention is as follows. The second embodiment of the present invention is proposed based on the first embodiment. In the second embodiment, sending the lighting effect data to the lighting controller includes:

[0091] Determine whether the lighting effect data is static lighting effect data or dynamic lighting effect data; when the lighting effect data is static lighting effect data, send the static lighting effect data to the lighting controller; when the lighting effect data is dynamic lighting effect data, split the dynamic lighting effect data to obtain processed image data, and send the processed image data to the lighting controller.

[0092] In this embodiment, in order to determine whether the lighting effect data is static lighting effect data or dynamic lighting effect data, the format of the lighting effect data is obtained, and the lighting effect data is determined to be static lighting effect data or dynamic lighting effect data according to the format of the lighting effect data. For example, when the format of the lighting effect data is PNG format, the lighting effect data is determined to be static lighting effect data, and when the format of the lighting effect data is GIF format, the lighting effect data is determined to be dynamic lighting effect data. Continue as follows Figure 4 As shown, it is determined whether the lighting effect data is static or dynamic. When it is static, the image data is directly sent. When it is dynamic, it is split and processed to obtain the image data, and then the image data is sent. In this way, the redundancy of communication is reduced by separating the dynamic lighting effect from the static lighting effect.

[0093] In one embodiment, the decoder includes a static decoder and a dynamic decoder, and step S30 includes:

[0094] Step S301, when the lighting effect data is composed of static frames, the lighting effect data is sent to the static decoder and decoded by the static decoder.

[0095] Continue as Figure 4 As shown, the decoding process is handled by the decoder in the light controller. The light controller obtains the lighting effect data sent by the body controller, determines whether it is a static frame or a dynamic frame, and decodes it through a static decoder when it is a static frame. When it is a static frame, it is decoded through a dynamic decoder, and the decoded lighting effect is used for lighting control.

[0096] Step S302, when the lighting effect data is composed of dynamic frames, the lighting effect data is sent to the dynamic decoder and decoded by the dynamic decoder.

[0097] In this embodiment, the lighting effect data is divided into static lighting effect data and dynamic lighting effect data, and transmitted to the vehicle speed controller separately, thereby improving the transmission efficiency, and corresponding static decoders and dynamic decoders are used for decoding according to the static lighting effect data and the dynamic lighting effect data, thereby realizing effective decoding processing and ensuring the correctness of the decoding.

[0098] Reference Figure 6 , Figure 6The third embodiment of the lighting effect display method of the present invention is a flow chart of the third embodiment of the present invention. The third embodiment of the present invention is proposed based on the first embodiment. In the third embodiment, the lighting effect data is obtained by compression and packaging through the encoder in the host, including:

[0099] Step S101, obtaining a lighting effect sample to be processed.

[0100] In this embodiment, the main process is to create lighting effects. During the lighting effect creation process, encoding is mainly performed through an encoder in the host. The lighting effect samples to be processed are lighting effect data that have not been encoded. After encoding the lighting effect data that has not been encoded, the display format is the same as the original image. However, due to the compression encoding process, the amount of lighting effect data after encoding is smaller.

[0101] Step S102, when the lighting effect sample to be processed is an image sample, separate the foreground image and the background image in the image sample, and compress and encapsulate the foreground image and the background image to obtain lighting effect data.

[0102] It should be noted that, since static images and dynamic images are encoded in different ways, when encoding static images, they are encoded using an image encoder, and when encoding dynamic images, they are encoded using an animation encoder, thereby ensuring the accuracy of the encoding.

[0103] Step S103, when the lighting effect sample to be processed is an animation sample, separate the dynamic image and the static image in the animation sample, and compress and package the dynamic image and the static image to obtain lighting effect data.

[0104] In this embodiment, the image encoder separates the image foreground and background before compressing the image samples to reduce the amount of background data. When processing animation encoding, the dynamic part and the static part are separated by traversal to reduce the amount of animation data.

[0105] In one embodiment, step S102 includes:

[0106] When the lighting effect samples to be processed are image samples, the image samples are matrixed to obtain an image array. The image samples are matrixed to denoise the pixels of the image samples and filter out pixels with unclear features to obtain an image array with obvious features.

[0107] When the headlight is a multi-color headlight, the image array is separated into channels according to pixel colors; the array corresponding to each channel is binarized, and the foreground image and the background image in the array are separated through the binarized image array; the foreground images of each channel are coupled through preset weights to obtain an integrated foreground image; the integrated foreground image is restored to obtain a restored foreground multi-color image, and the restoration method can be a mask method or other methods. This embodiment does not limit this. The integrated foreground image is restored so that the processed image display is more realistic, and the restored foreground multi-color image is pixelated to reduce the resolution of the integrated foreground image; then the pixelated foreground image is compressed using a first compression method to obtain a compressed foreground image; the compressed foreground image and the background image are encapsulated to obtain lighting effect data.

[0108] like Figure 7 The flowchart of creating lighting effects through an image encoder is shown, wherein the first compression method can be a PNG compression method or other compression methods. This embodiment does not limit this. The PNG compression method is taken as an example for explanation. After obtaining the pixelated foreground image, the PNG compression method is used for compression and data encapsulation to obtain the created image lighting effect data. The image foreground and background are separated by the image encoder before PNG compression. Since the display requirements of the image are not high for the lighting effect, the foreground and background are separated to reduce the amount of background data, thereby improving the processing efficiency of the image data.

[0109] In one embodiment, when the lighting effect samples to be processed are image samples, after matrixing the image samples to obtain an image array, the method further includes:

[0110] When the vehicle light is a monochrome light, the image array is gray-binarized, and the main image portion is determined by the binarized image array; the contour position is determined according to the main image portion; the foreground image and the background image are extracted according to the contour position; the foreground image is restored by masking to obtain a restored foreground grayscale image; the restored foreground grayscale image is compressed by a second compression method to obtain a compressed foreground image; the compressed foreground image and the background image are encapsulated to obtain lighting effect data.

[0111] In this embodiment, since the processing methods of monochrome images and multi-color images are different, after determining the monochrome image and the multi-color image, lighting effect encoding processing is performed separately, wherein the second compression method can be a PNG compression method, or other compression methods. This embodiment does not limit this, and takes the PNG compression method as an example for explanation. After obtaining the pixelated foreground image, the PNG compression method is used for compression and data encapsulation to obtain the created image lighting effect data. The image encoder is used to separate the image foreground and background before PNG compression, thereby reducing the amount of background data and improving the processing efficiency of image data.

[0112] In one embodiment, step S103 includes:

[0113] When the lighting effect sample to be processed is an animation sample, the animation sample is disassembled to obtain each frame image information; each frame image information is pixelated to obtain an image with a changed position and an image with an unchanged position; the image with a changed position is used as a foreground image, and the image with an unchanged position is used as a background image; the foreground image and the background image in each frame image information are respectively extracted; a dynamic scene frame is extracted from the foreground image in each frame image information to obtain a dynamic image, and the background image in each frame image information is used as a static image; the dynamic image is compressed using a third compression method to obtain a compressed dynamic image; the compressed dynamic image is encapsulated with the background image in each frame image information to obtain lighting effect data.

[0114] like Figure 8 The flowchart of creating lighting effects through an animation encoder is shown, which obtains the loaded animation or hand-drawing, restores the animation or hand-drawing to a bmp image, and pixelates it frame by frame, extracts the dynamic scene frame, and then compresses the dynamic scene frame into a GIF format, and finally encapsulates the data to obtain the lighting effect data of the animation. During the animation encoding process, the dynamic part and the static part are separated by traversal, thereby reducing the amount of animation data.

[0115] like Fig. 9 The overall process diagram of lighting effect creation is shown. When the user needs to create a lighting effect, it is determined whether it is static or dynamic. When it is a static image, it is encoded through an image encoder, and when it is a dynamic image, it is encoded through a video encoder. The encoded lighting effect data is saved in the local host database, and the host is connected to the body controller through Ethernet. The lighting effect data is transmitted to the body controller through Ethernet. The body controller saves the lighting effect data received through Ethernet in the local database of the body, and can also save it in the cloud archive and save it in the cloud database of the body controller, thereby realizing the caching of lighting effect data to facilitate the call of the encoded lighting effect data.

[0116] The present invention further provides a lighting effect display device.

[0117] Reference Fig.10 , Fig.10 Schematic diagram of functional modules of the first embodiment of the lighting effect display device of the present invention.

[0118] In a first embodiment of the lighting effect display device of the present invention, the lighting effect display device comprises:

[0121] The decoding module 30 is used to decode the lighting effect data through a decoder in the lighting controller to obtain target lighting effect data, and control the vehicle lights to display the lighting effect according to the target lighting effect data.

[0122] In this embodiment, the lighting effect information to be displayed is obtained, and the lighting effect information to be displayed is sent to the body controller; the tag information of the lighting effect information to be displayed is extracted by the body controller, and the lighting effect data is obtained from a preset database according to the tag information, and the lighting effect data is sent to the light controller, wherein the lighting effect data is compressed and packaged by the encoder in the host; the lighting effect data is decoded by the decoder in the light controller to obtain target lighting effect data, and the vehicle lights are controlled to display the lighting effects according to the target lighting effect data, so that when performing a customized lighting effect display, only the encoded lighting effect data needs to be sent to the light controller for displaying the lighting effect, and since the amount of data of the encoded lighting effect data is small, lightweight data transmission is achieved, and the data transmission amount and CAN bus load are reduced.
