[0039] The following will elaborate in detail on the main implementation principles, specific implementation manners, and corresponding beneficial effects that can be achieved of the technical solutions of the embodiments of the present application with reference to the accompanying drawings.

[0040] Embodiment

[0041] Please refer to Figure 1 , an embodiment of the present application provides a method for processing an automotive starry sky ceiling image, and the method includes:

[0042] S101. According to the pixel data in the obtained starry sky playback data, establish a two-dimensional array, and store the color value corresponding to each pixel in the storage address of each pixel array in the two-dimensional array;

[0043] S102. Determine N two-dimensional data for starry sky projection from the two-dimensional array according to the color values stored in the storage addresses of the two-dimensional array, where N is an integer greater than 1;

[0044] S103. According to the N two-dimensional data, obtain N starry sky lights corresponding to the N two-dimensional data from the starry sky light array in the starry sky ceiling;

[0045] S104. Turn on the N starry sky lights in the starry sky light array, and control the remaining starry sky lights to be in an off state, where the remaining starry sky lights are the starry sky lights other than the N starry sky lights in the starry sky light array.

[0046] In the embodiments of this specification, the vehicle may include a fuel vehicle and an electric vehicle. The electric vehicle may be, for example, a pure electric vehicle, an extended-range electric vehicle, a hybrid vehicle, a fuel cell electric vehicle, and a hydrogen engine vehicle, etc.

[0047] Among them, in step S101, first obtain starry sky playback data. The starry sky playback data can be video data or picture data containing starry sky images. After obtaining the starry sky playback data, obtain the pixel data in the starry sky playback data, and then establish a two-dimensional array according to the pixel data in the starry sky playback data.

[0048] Specifically, when establishing a two-dimensional array according to the pixel data in the starry sky playback data, a two-dimensional array can be established to define the coordinates of each pixel according to the coordinates of each pixel in the pixel data, and a two-dimensional array can be obtained according to the established coordinates of each pixel; or a two-dimensional coordinate matching the resolution of the data frame picture can be established according to the resolution corresponding to the pixel data, and then the coordinates in the two-dimensional coordinate are corresponding to the coordinates of each pixel in the pixel data, thereby establishing a two-dimensional array.

[0049] Specifically, if the starry sky playback data is video data, extract the data according to a set duration to obtain a set of data frame pictures; for the pixel data in each data frame picture in the set of data frame pictures, establish a two-dimensional array, and for each data frame picture, execute steps S101 - S104. Among them, when establishing a two-dimensional array for the pixel data in each data frame picture in the set of data frame pictures, for each data frame picture in the set of data frame pictures, a two-dimensional coordinate matching the resolution of the data frame picture can be established according to the resolution of the data frame picture; then, according to the position of each pixel in the data frame picture, obtain the two-dimensional data of each pixel in the established two-dimensional coordinate; establish a two-dimensional data according to the two-dimensional data of each pixel.

[0050] In addition, when establishing a two-dimensional coordinate matching the resolution of the data frame picture for each data frame picture in the set of data frame pictures, any pixel in the data frame picture can be used as the origin to establish a two-dimensional coordinate matching the resolution of the data frame picture based on the origin; or an origin can be preset outside the data frame picture, and then a two-dimensional coordinate matching the resolution of the data frame picture can be established based on the origin. Preferably, the first pixel in the data frame picture can be used as the origin to establish a two-dimensional coordinate matching the resolution of the data frame picture.

[0051] In the embodiments of this specification, the set duration can be set according to actual needs, or can be set manually or by the device itself. The set duration can be, for example, 100 milliseconds (ms), 200 ms, 500 ms, 800 ms, etc.

[0052] Specifically, if the starry sky playback data is a starry sky image, a two-dimensional array is directly established according to the pixel data in the starry sky playback data. The establishment method specifically refers to the establishment method when the starry sky playback data is video data. For the sake of simplicity of the specification, it will not be elaborated here.

[0053] Moreover, after establishing the two-dimensional array, obtain the color value of each pixel in the playback data. For example, it can be an RGB value or a grayscale value. For each pixel, store the color value of the pixel at the storage address of the pixel in the two-dimensional array. For example, taking pixel A as an example, determine the storage address of A in the two-dimensional array as A1, and store the color value of A in A1.

[0054] In the actual application process, the starry sky playback data is usually stored in the vehicle's multimedia system. When obtaining the starry sky playback data, it needs to be selected from the multimedia system. After selecting the starry sky playback data, the multimedia system will execute steps S101 - S103, and then send N starry sky lights to the body controller; when executing step S104, at this time, the body controller will generate a control command according to the received N starry sky lights, and the body controller will transmit the control command to the starry sky ceiling electronic control unit (Electronic Control Unit, abbreviated as ECU), and then the starry sky ceiling ECU will execute step S104.

[0055] After establishing the two-dimensional array, execute step S102.

[0056] In step S102, the color values of every two adjacent pixels in the two-dimensional array can be compared according to the color values stored at the storage addresses of the two-dimensional array to obtain N pixels whose color change value is greater than the set value; obtain the two-dimensional data corresponding to the N pixels from the two-dimensional array as N two-dimensional data. Of course, the color values of every three or more adjacent pixels can also be compared to obtain N pixels whose color change value is greater than the set value; obtain the two-dimensional data corresponding to the N pixels from the two-dimensional array as N two-dimensional data.

[0057] In another embodiment, the two-dimensional array can also be divided into multiple small regions according to the color values stored at the storage addresses of the two-dimensional array. For each small region among the multiple small regions, obtain the pixels whose color value difference within the small region is greater than the set value, and use the two-dimensional data corresponding to all the pixels whose color change value within each small region is greater than the set value as N two-dimensional data. Among them, the set value can be set according to actual needs, or can be set manually or by the device itself, and this specification does not make specific limitations.

[0058] Since the color difference value between each pixel point corresponding to each of the N two-dimensional data obtained and its adjacent pixel points is greater than the set value, the N two-dimensional data can well reflect the starry sky contour in the starry sky playback data.

[0059] In another embodiment of this specification, after determining N two-dimensional data for starry sky projection from a two-dimensional array, a projection sketch boundary may also be determined according to the N two-dimensional data, where the projection sketch boundary is an image composed of the N two-dimensional data.

[0060] After determining the N two-dimensional data, step S103 is executed.

[0061] In step S103, first, obtain the starry sky lamp array in the starry sky ceiling, and then establish a starry sky coordinate system for the starry sky lamp array; after establishing the starry sky coordinate system, if the projection sketch boundary has not been obtained, directly project the N two-dimensional data into the starry sky coordinate system to obtain N starry sky lamp coordinates mapped by the N two-dimensional data; obtain the N starry sky lamps corresponding to the N starry sky lamp coordinates; if the projection sketch boundary has been obtained, map the projection sketch boundary into the starry sky coordinate system according to a ratio to obtain N starry sky lamp coordinates mapped by the N two-dimensional data; obtain the N starry sky lamps corresponding to the N starry sky lamp coordinates. The N starry sky lamps may be the addresses of the N starry sky lamps. When each starry sky lamp has an identifier, the N starry sky lamps may also be the addresses of the N starry sky lamps. This specification does not make specific limitations.

[0062] Since the N two-dimensional data can well reflect the starry sky contour in the starry sky playback data, thus, when applying current to the N starry sky lamps mapped by the N two-dimensional data and turning off the remaining starry sky lamps, the starry sky lamp array can also better reflect the starry sky contour in the starry sky playback data.

[0063] After obtaining the N starry sky lamps, step S104 is executed.

[0064] In step S104, after determining the N starry sky lamps, obtain the remaining starry sky lamps in the starry sky lamp array except the N starry sky lamps, then generate a control command to turn on the N starry sky lamps and turn off the remaining starry sky lamps, send the control command to the starry sky lamp array, and then turn on the N starry sky lamps in the starry sky lamp array and turn off each of the remaining starry sky lamps, thereby achieving turning on the N starry sky lamps and controlling the remaining starry sky lamps to be in an off state.

[0065] Specifically, when turning on the N starry sky lamps, the N starry sky lamps may be turned on according to the addresses of the N starry sky lamps; and the remaining starry sky lamps are controlled to be in an off state according to the addresses of each of the remaining starry sky lamps.

[0066] In the actual application process, after determining N star lights and the remaining star lights, the body controller will automatically generate a control command to turn on the N star lights and turn off the remaining star lights, and then send the control command to the star ceiling ECU. The star ceiling ECU obtains the addresses of the N star lights in the control command according to the control command and turns on the N star lights; and obtains the addresses of each of the remaining star lights in the control command to control the remaining star lights to be in the off state.

[0067] When the star playback data is star video data, since the video data consists of multiple frame data pictures, thus, the multiple frame data pictures can be processed in sequence, continuously controlling the lighting and extinguishing of the star lights in the star light array. After processing the last frame data picture, start processing from the first frame data picture, and so on in a loop, continuously sending the processed message data, then the dynamic lighting effect of the star ceiling according to the star video loaded by the vehicle user can be achieved.

[0068] In the actual application process, as Figure 2 shown, the method for processing the automotive star ceiling image provided in the embodiments of this specification is applied in an automotive star ceiling image projection system. The system includes a multimedia system 20, a body controller 30, a star ceiling ECU 40, and a star light array 50. Among them, the multimedia system 20 includes a multimedia display screen 201, a multimedia file library 202, and a star ceiling image processing application program 203. Of course, the star ceiling image processing application program 203 can also be deployed in the body controller 30, and this specification does not make specific limitations.

[0069] Among them, the projection system further includes four-door status acquisition micro switches 60 for triggering the lighting of each star light. The four-door status acquisition micro switches 60 are electrically connected to the body controller 30; and the star light array includes a lamp head 501 with an address of x0, y0; a lamp head 502 with an address of x1, y0; a lamp head 503 with an address of x2, y0; a lamp head 504 with an address of x0, y1; a lamp head 505 with an address of x1, y1; a lamp head 506 with an address of x2, y1.

[0070] Specifically speaking, first, after the vehicle uses and completes data loading, video or picture data is loaded in the star ceiling image processing application program 203. The star ceiling image processing application program 203 processes the picture through the following steps and feeds back to the operator whether the data entry is successful in a pop-up window manner, which specifically includes the following steps:

[0071] A1. If the loaded data is a video file, first extract the data at intervals of 500 ms (to reduce the memory consumption caused by the images extracted from the video). After obtaining the data frame images, store the extracted images according to the extraction time. If the loaded data is an image, store it directly.

[0072] A2. Establish coordinates: Based on the stored data, the resolution can be obtained. Starting from the first pixel of the image, create an empty two-dimensional array that matches the length of the resolution to define the coordinates of the image.

[0073] A3. Obtain color values: Obtain the RGB color values of each pixel in each image, and use the address of the two-dimensional array to store the RGB color values corresponding to the pixel coordinates.

[0074] A4. Outline the boundary: Use an algorithm to compare adjacent RGB color values to find the pixel points with large pixel mutations, and outline the sketch boundary of the image.

[0075] A5. Mapping projection: According to the arrangement of the lamp heads on the starry sky ceiling, first determine the two-dimensional coordinates of the lamp heads, and enter its resolution into the starry sky ceiling image processing application program. Map the outlined sketch boundary proportionally to the two-dimensional coordinates of the starry sky ceiling lamp heads. According to the mapping result, obtain a set of lamp head addresses that need to be lit on the starry sky ceiling, and the remaining are the lamp head addresses that are not lit.

[0076] A6. Output control: Next, the multimedia system 20 converts the lit and unlit lamp head addresses into automotive CAN bus messages and transmits them to the body controller 30 in multiple frames. The body controller 30 then converts the bus messages into LIN bus messages and sends them to the starry sky ceiling ECU 40. The starry sky ceiling ECU 40 performs multi-frame message parsing to obtain the complete lamp head addresses that need to be controlled to be lit and extinguished, and drives the lamp heads that need to be lit to complete the control.

[0077] In the actual application process, as long as the starry sky ceiling switch is not turned off, continuously process the stored images and continuously control the lighting of the starry sky ceiling. If the processed data is video data, the processing steps from A3 to A6 will be repeated. After processing each image in turn, return to the initial state to process the first photo, and so on in a loop. By continuously sending the processed message data, the effect of dynamically lighting the starry sky ceiling according to the video loaded by the vehicle user can be achieved.

[0078] Such as Figure 3As shown in the figure, this specification provides a schematic flowchart of the lighting logic of an automotive starry sky ceiling image projection system, including the following steps: B1. Load data; after loading the data, if it is video data, then execute steps B2 - B3; if it is a picture, directly execute step B3; where step B2. Extract pictures; then execute step B3. Store pictures; after storing the pictures, execute step B4. Establish coordinates; and after establishing coordinates, execute step B5. Obtain color values; and after obtaining color values, execute step B6. Outline the boundary; after outlining the boundary, execute step B7. Map the projection; after mapping the projection, execute step B8. Output; after executing step B8, execute step B9. Determine whether it is a video; if so, sequentially execute B5 - B9 for the next frame of picture; if not, execute step B10. Determine whether to turn off the starry sky ceiling, if not, return to execute B4 - B9.
