[0020] See also Figure 1 , Figure 1 A schematic diagram of a double-sided display synchronization method for a double-sided transparent screen provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the double-sided display synchronization method of the double-sided transparent screen provided in the embodiment of the present application includes steps S1 to S5.

[0021] Step S1: Acquire an initial image, and filter the initial image based on a preset image filtering algorithm to obtain a first target image.

[0022] The initial image includes but is not limited to an image stored in a database, an image obtained by a camera, an image obtained from the Internet, or any image frame in a video. Specifically, filtering the initial image based on a preset image filtering algorithm to obtain a first target image includes the following steps: For each initial pixel of the initial image, the initial pixel is taken as the central pixel, and the initial pixels adjacent to the initial pixel are taken as adjacent pixels to obtain a pixel domain corresponding to the initial pixel, and denoising is performed on the central pixel based on the pixel domain to obtain a target pixel corresponding to the central pixel; each of the target pixels constitutes the first target image.

[0023] The denoising process is performed on the central pixel based on the pixel domain to obtain a target pixel corresponding to the central pixel, comprising the following steps: For each initial pixel in the pixel domain, a first target weight coefficient, a second target weight coefficient and a third target weight coefficient corresponding to the initial pixel are generated based on a preset weight coefficient generation algorithm; the first target weight coefficient is a weight coefficient corresponding to the red value of the initial pixel, the second target weight coefficient is a weight coefficient corresponding to the blue value of the initial pixel, and the third target weight coefficient is a weight coefficient corresponding to the green value of the initial pixel; it can be understood that the initial pixel in this step includes the central pixel and the adjacent pixels in the neighborhood pixels; Based on the first target weight coefficient corresponding to each initial pixel in the pixel domain, weighted sum is performed on the red values ​​of each initial pixel in the pixel domain to obtain a target red value corresponding to the central pixel; performing weighted summation on the blue values ​​of each initial pixel in the pixel domain based on the second target weight coefficient corresponding to each initial pixel in the pixel domain to obtain a target blue value corresponding to the central pixel; performing weighted summation on the green values ​​of each initial pixel in the pixel domain based on a third target weight coefficient corresponding to each initial pixel in the pixel domain to obtain a target green value corresponding to the central pixel; The RGB space of the central pixel is updated based on the target red value, the target blue value, and the target green value to obtain a target pixel corresponding to the central pixel.

[0024] It can be understood that the above-mentioned method of filtering the initial image based on a preset image filtering algorithm to obtain the first target image can more accurately identify and eliminate noise while retaining the main structure and details of the image, on the one hand, and effectively avoid color distortion, maintain the true color and natural transition of the image, and enhance the overall visual effect of the image by filtering each color channel of each pixel of the initial image respectively.

[0025] The step of generating the first target weight coefficient corresponding to the initial pixel based on a preset weight coefficient generation algorithm comprises the following steps: Based on a preset spatial weight coefficient acquisition algorithm, respectively acquire the spatial weight coefficient corresponding to each initial pixel in the pixel domain; Based on a preset color value similarity weight coefficient acquisition algorithm, respectively acquire the color similarity weight coefficient corresponding to each initial pixel in the pixel domain; For each initial pixel in the pixel domain, multiplying the spatial weight coefficient corresponding to the initial pixel by the color similarity weight coefficient to obtain a first intermediate weight coefficient corresponding to the initial pixel; Adding the first intermediate weight coefficients corresponding to the initial pixels in the pixel domain to obtain a sum of the weight coefficients; For each initial pixel in the pixel domain, a ratio of a first intermediate weight coefficient corresponding to the initial pixel to the sum of the weight coefficients is determined as a first target weight coefficient corresponding to the initial pixel.

[0026] The step of respectively acquiring the spatial weight coefficients corresponding to the initial pixels in the pixel domain based on a preset spatial weight coefficient acquisition algorithm comprises the following steps: Constructing a plane rectangular coordinate system with the center point of the initial image as the coordinate origin; Acquire the central coordinate point of the central pixel of the pixel region based on the plane rectangular coordinate system ; For each initial pixel in the pixel domain, the coordinate point of the initial pixel is obtained based on the plane rectangular coordinate system. and through Obtain the spatial weight coefficient of the initial pixel; wherein, is the spatial weight coefficient of the initial pixel, is the standard deviation of the distance values ​​from each adjacent pixel to the middle pixel in the pixel domain.

[0027] The method of respectively obtaining the color similarity weight coefficient corresponding to each initial pixel in the pixel domain based on a preset color value similarity weight coefficient obtaining algorithm comprises the following steps: Get the red value of the center pixel of the pixel domain ; For each initial pixel in the pixel domain, obtain the red value of the initial pixel and through Obtain the color similarity weight coefficient of the initial pixel, where: is the color similarity weight coefficient of the initial pixel, is the standard deviation between the red values ​​of each original pixel in the pixel domain.

[0028] It should be noted that the method for obtaining the second target weight coefficient and the third target weight coefficient refers to the method for obtaining the first target weight coefficient mentioned above, which will not be repeated here.

[0029] It can be understood that the above method can more accurately identify and suppress noise in the image by combining the spatial weight coefficient and the color similarity weight coefficient. The spatial weight coefficient takes into account the spatial distance between pixels, and the color similarity weight coefficient is based on the similarity of pixel colors. The combination of the two effectively improves the accuracy of denoising, reduces the impact of noise on image quality, and helps to improve the display effect of the image.

[0030] Step S2: Rotate the first target image by 180 degrees based on a preset rotation axis of the first target image to obtain a second target image. The preset rotation axis refers to a dividing line between the left half and the right half of the first target image. It can be understood that the back side of the first target image is opposite to the back side of the second target image.

[0031] Step S3: construct a plane rectangular coordinate system with the center point of the first target image as the coordinate origin, and construct a plane rectangular coordinate system with the center point of the second target image as the coordinate origin.

[0032] Specifically, a plane rectangular coordinate system is constructed on the front side of the first target image, and a plane rectangular coordinate system is constructed on the back side of the second target image.

[0033] Step S4: for a first pixel and a second pixel at the same coordinate point, perform contrast analysis on the first pixel and the second pixel, and determine a first transparency of the first pixel and a second transparency of the second pixel based on a result of the contrast analysis; the first pixel is a pixel in the first target image, and the second pixel is a pixel in the second target image.

[0034] Specifically, performing contrast analysis on the first pixel and the second pixel, and determining a first transparency of the first pixel and a second transparency of the second pixel based on a result of the contrast analysis, comprises the following steps: Obtain a first RGB color space corresponding to the first pixel, and obtain a second RGB color space corresponding to the second pixel; Obtaining an absolute difference space between the first RGB color space and the second RGB color space; wherein the absolute difference space includes a red absolute difference, a blue absolute difference, and a green absolute difference; Comparing any absolute difference in the absolute difference space with a preset absolute difference respectively; If each of the absolute difference values ​​is less than the preset absolute difference value, it is determined that the first transparency and the second transparency are the original transparency of the double-sided transparent screen; it can be understood that if each of the absolute difference values ​​is less than the preset absolute difference, it means that the RGB color space of the first pixel and the second pixel has a high similarity, and when the first pixel and the second pixel are displayed using the original transparency, the display effects of the first pixel and the second pixel will not cause significant mutual interference. At this time, using the original transparency to display the first pixel and the second pixel helps to ensure the overall transparency effect of the double-sided transparent screen; If any of the absolute difference values ​​is greater than the preset absolute difference value, the first transparency and the second transparency are determined to be preset transparencies; wherein the preset transparency is less than the original transparency; it can be understood that if any of the absolute difference values ​​is greater than the preset absolute difference value, it means that the similarity between the RGB color space of the first pixel and the second pixel is low, and when the first pixel and the second pixel are displayed using the original transparency, the display effects of the first pixel and the second pixel will produce large mutual interference. At this time, using the preset transparency to display the first pixel and the second pixel helps to reduce the mutual interference between the first pixel and the second pixel.

[0035] Step S5: displaying the first target image on a first display panel based on a first transparency of each of the first pixels, and displaying the second target image on a second display panel based on a second transparency of each of the second pixels, wherein the first display panel and the second display panel are arranged opposite to each other in a double-sided transparent screen.

[0036] The method provided in this embodiment, on the one hand, reduces the influence of noise on image quality and ensures the clarity and color information of the image by filtering the initial image, and on the other hand, reduces the mutual interference between the images of the two display panels by performing contrast analysis on the first pixel and the second pixel and determining the first transparency of the first pixel and the second transparency of the second pixel based on the result of the contrast analysis, thereby ensuring the clarity and authenticity of the image display and taking into account the overall transparency effect of the double-sided transparent screen.
