[0052] The method, device, and electronic device for adjusting the picture of a rotating display provided by the embodiments of the present application are specifically described through the following embodiments. First, the method for adjusting the picture of a rotating display in the embodiments of the present application is described.

[0055] The following further elaborates on the embodiments of the present application with reference to the accompanying drawings.

[0056] As Figure 1 shown, Figure 1 is an optional flowchart of the method for adjusting the screen of a rotating display provided by an embodiment of the present application. The method for adjusting the screen of a rotating display can be executed by a server, or can also be executed by a terminal, or can also be executed by a server in cooperation with a terminal. The method for adjusting the screen of a rotating display includes but is not limited to the following steps S110 to step S130:

[0057] Step S110, when at a target sampling point, respectively collect the reference angle and the first reference coordinates of each first light-emitting element, where the reference angle refers to the angle between the line connecting the corresponding first light-emitting element and the first rotation center axis and a preset horizontal baseline at the target sampling point;

[0058] Step S120: Obtain the rotation rate of each first light-emitting element and the target time point. According to the target time point, each first reference coordinate, each reference angle, and the rotation rate, determine the first target coordinates of each first light-emitting element, where the first target coordinates represent the positions where the first light-emitting elements are located when the target time point is reached, and the target time point is after the target sampling point.

[0059] Step S130: Obtain image information. When the target time point is reached, control the working states of the first light-emitting elements according to the first target coordinates and the image information.

[0060] Specifically, the reference angle is collected by an inclination sensor installed on the first rotation center axis of the rotating display.

[0061] It can be understood that during the continuous rotation of the first display screen, the first display screen collects the angles between the lines connecting each first light-emitting element and the first rotation center axis and the horizontal baseline at a specific frequency. After reaching the current target sampling point and before the next target sampling point, by obtaining the rotation rate and the target time point, calculating the difference between the target time point and the current target sampling point, the angle swept by the first light-emitting element from the current target sampling point to the target time point can be determined. Through the reference angle and the first reference coordinates collected by each first light-emitting element at the current target sampling point, the first target coordinates of each first light-emitting element at the target time point can be determined. Combining the positions of each pixel point in the preset image information and controlling the working states of the first light-emitting elements, the image information can be continuously and positively displayed on the rotating first display screen. The screen adjustment method proposed in this application can accurately analyze the first target positions of each first light-emitting element between two adjacent target sampling points without rotating the image information, so as to sensitively adjust the working states of the first light-emitting elements according to the image information, reduce the visual rotation deviation of the image on the first display screen due to the sampling interval, optimize the display effect of the rotating display, and improve the clarity of the first display screen.

[0062] In addition, referring to Figure 2 shown in the figure, in some embodiments of the present application, the image information includes a plurality of initial pixel information. Figure 1 The method step S130 in

[0063] includes, but is not limited to, the following steps S210 to S220:

[0064] Step S210: When the target time point is reached, determine the initial pixel information corresponding to each first light-emitting element according to the first target coordinates.

[0064] Step S220: Perform filtering processing on the initial pixel information to obtain the target pixel information corresponding to each first light-emitting element.

[0065] In a specific embodiment, the initial pixel information is the RGB color value of a pixel point, and the initial pixel information of adjacent pixel points is weighted by a preset color weight value to obtain the target pixel information;

[0066] Exemplarily, referring to Figure 3 as shown, the initial pixel information of the pixel points in the 3×3 grid is obtained. The initial pixel information is successively RGB1=(123, 213, 213), RGB2=(132, 206, 232), RGB3=(133, 221, 212), RGB4=(123, 221, 213), RGB5=(123, 213, 213), RGB6=(122, 211, 222), RGB7=(112, 231, 223), RGB8=(121, 213, 213), RGB9=(123, 216, 213), and the color weight value of each initial pixel information is Therefore, the result of the weighted processing of the above initial pixel information is:

[0067]

[0068] In an embodiment, referring to Figure 4 as shown, the initial pixel information includes the initial gray value corresponding to each first light-emitting element, and the target pixel information includes the target gray value corresponding to each first light-emitting element. The formula for filtering the initial pixel information is:

[0069]

[0070] wherein, C(x0, y0) represents the initial gray value of the first light-emitting element with the first target coordinate (x0, y0), C(x1, y1) represents the initial gray value of the first light-emitting element with the first target coordinate (x1, y1), C(x2, y1) represents the initial gray value of the first light-emitting element with the first target coordinate (x2, y1), C(x1, y2) represents the initial gray value of the first light-emitting element with the first target coordinate (x1, y2), C(x2, y2) represents the initial gray value of the first light-emitting element with the first target coordinate (x2, y2), and the values of (x2 - x1), (x0 - x1), (y2 - y0), and (y0 - y1) are all less than the preset distance threshold.

[0071] It can be understood that by filtering the initial pixel information, random noise in the image information can be removed or reduced, making the image look clearer and smoother. It can also reduce the jagged effect in the image information, making the image information look softer. Moreover, in the rotating first display surface, filtering can reduce the visual blur caused by rotation and enhance the viewing experience.

[0072] In addition, referring to Figure 5 as shown, in some embodiments of the present application, Figure 1 step S120 includes, but is not limited to, the following steps S510 to S530:

[0073] Step S510, obtaining historical sampling points and the initial angles of each first light-emitting element at each historical sampling point;

[0074] Step S520, filtering each initial angle to obtain the historical angles of each first light-emitting element at each historical sampling point;

[0075] Step S530, determining the rotation rate of the first light-emitting element according to each historical angle and its corresponding historical sampling point, and each reference angle and its corresponding target sampling point, where the calculation formula for the rotation rate is:

[0076]

[0077] where V t represents the rotation rate of the first light-emitting element at the target sampling point, T i represents the i-th historical sampling point, A i represents the historical angle of the first light-emitting element at the i-th historical sampling point, T n represents the n-th historical sampling point, A n represents the historical angle of the first light-emitting element at the n-th historical sampling point, T t represents the target sampling point, A t represents the reference angle of the first light-emitting element at the target sampling point, and n represents the number of historical sampling points.

[0078] It can be understood that based on the current target sampling point, obtaining n historical sampling points and their corresponding historical angles forward, and determining the rotation rate of the first light-emitting element within n + 1 sampling points based on the current target sampling point and reference angle, as well as n historical sampling points and their corresponding historical angles, can ensure the effectiveness of the rotation rate and improve the accuracy of judging the position of the first light-emitting element.

[0079] In addition, referring to Figure 6 as shown, in some embodiments of the present application, Figure 5Step S520 therein includes, but is not limited to, the following steps S610 to S620:

[0080] Step S610: Taking the historical sampling point as the center, obtaining the corresponding mirror sampling points and the initial angles of each first light-emitting element at the mirror sampling points;

[0081] Step S620: Obtaining the filtering weights of each initial angle, and based on each initial angle and its corresponding filtering weight, performing filtering processing on the initial angle corresponding to the current historical sampling point to obtain the historical angle of the first light-emitting element at the current historical sampling point, where the sum of all filtering weights is equal to 1, and the calculation formula for the filtering processing is:

[0082]

[0083] where the number of initial angles is equal to 2m + 1, a t-j represents the initial angle of the first light-emitting element at the (t - j)-th mirror sampling point, ω t-j represents the filtering weight corresponding to the (t - j)-th initial angle, a t+j represents the initial angle of the first light-emitting element at the (t + j)-th mirror sampling point, ω t+j represents the filtering weight corresponding to the (t + j)-th initial angle, a t represents the initial angle of the first light-emitting element at the current historical sampling point, ω t represents the filtering weight corresponding to the current historical sampling point, and for any j, ω t > ω t-j > ω t-j-1 , ω t > ω t+j > ω t+j+1 ,

[0084] It can be understood that during the process of sampling the angle of the first display surface, the sampling values often have noise fluctuations. Therefore, by taking the current historical sampling point as the center, obtaining multiple mirror sampling points and their corresponding initial angles forward and backward, and performing filtering processing on the initial angle of the current historical sampling point through the above initial angles. Since the initial angles of each mirror sampling point and the initial angle of the current historical sampling point are collected by the same sampling device, there are positive errors and negative errors generated during the sampling process of the sampling device in the above initial angles. Therefore, by obtaining the filtering weights, the sum of all filtering weights is equal to 1, and the values of the filtering weights decrease from the center to both sides, emphasizing the value of the current historical angle. Based on each filtering weight and each initial angle, performing filtering processing on the initial angle of the current historical sampling point can effectively reduce the errors in the initial angles, and thus a more accurate historical angle can be obtained.

[0085] In addition, referring to Figure 7 as shown, for some embodiments of the present application, Figure 1 step S120 in

[0086] includes, but is not limited to, the following steps S710 to S720:

[0087] A * = V t × (T * - T t )

[0088] θ * = A * × π / 180°

[0089] wherein, A * represents the rotation angle, T * represents the target time point, and θ * represents the rotation radian;

[0090] Step S720, determine the first target coordinates of each first light-emitting element at the target time point according to the first center coordinates of the first rotation central axis, each first reference coordinate, and the target angle, wherein the calculation formula for the first target coordinates is:

[0091]

[0092] wherein, represents the first target coordinates of the first light-emitting element, (M x , M y ) represents the first reference coordinates of the first light-emitting element, represents the first center coordinates, and θ * represents the rotation radian.

[0093] In addition, referring to Figure 8 as shown, for some embodiments of the present application, the rotating display further includes a second display screen and a bracket. The back surface of the second display screen and the back surface of the first display screen are respectively fixedly connected to the bracket. The back surface of the second display screen is close to the back surface of the first display screen. The second rotation central axis of the second display screen coincides with the first rotation central axis. The second display screen rotates in the same direction as the first display screen. The second display screen includes a plurality of second light-emitting elements. The screen adjustment method further includes steps S810 to S820:

[0094] Step S810, when reaching the target sampling point, respectively collect the second reference coordinates of each second light-emitting element;

[0095] Step S820: When the target time point is reached, determine the second target coordinates of each second light-emitting element at the target time point according to the second central coordinates of the second rotation center axis, each second reference coordinate, and the target angle.
