Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The special-shaped screen display method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. The terminal 102 may be in communication connection with a sending device, and the sending device is connected to a receiving device to implement communication connection between the sending device and the special-shaped screen, where the receiving device is disposed in the special-shaped screen. After the worker performs the form adjustment on the special-shaped screen, the form adjustment information of the special-shaped screen can be input into the terminal 102, the terminal 102 can determine the picture adjustment information of an output picture in an output window corresponding to the special-shaped screen based on the form adjustment information of the special-shaped screen, and adjust each endpoint based on the picture adjustment information to obtain the endpoint adjustment information, so that the terminal 102 can determine a picture to be displayed in an original picture based on the endpoint adjustment information and output the picture to be displayed to the special-shaped screen after the form adjustment. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, and tablet computers. The special-shaped screen can be realized by a single special-shaped screen or a special-shaped screen combination consisting of a plurality of special-shaped screens.
In an embodiment, as shown in fig. 2, a method for displaying a special-shaped screen is provided, which is described by taking the method as an example for being applied to the terminal in fig. 1, and includes the following steps:
step S202, receiving the form adjustment information of the special-shaped screen, and determining the picture adjustment information of the output picture in the output window corresponding to the special-shaped screen according to the form adjustment information.
The special-shaped screen can be a polygonal LED screen, such as an LED magic cube, a diamond LED display screen, a gem-shaped LED display screen and the like. When the special-shaped screen displays the screen, a worker can have certain adjustment requirements on the special-shaped screen, and can perform shape adjustment on the special-shaped screen based on the adjustment requirements, wherein the shape adjustment comprises adjustment of the number and the position of the special-shaped screen and the like, and the adjustment requirements comprise but are not limited to operations of putting, rotating, replacing other special-shaped screens or adding new special-shaped screens to the original special-shaped screen again or the like. After the worker performs the form adjustment on the special-shaped screen, the form adjustment information can be input into the terminal 102, so that the terminal 102 can receive the form adjustment information of the special-shaped screen and determine the picture adjustment information of the output picture in the output window corresponding to the special-shaped screen based on the form adjustment information. For different adjustment requirements, the terminal 102 may have different screen adjustment modes for the screen. For example, when the special-shaped screen is repositioned, the terminal 102 may adjust the screen in a translational manner; when the special-shaped screen is exchanged for another special-shaped screen (for example, the special-shaped screen is exchanged for a screen with a consistent shape and a higher resolution) or a new special-shaped screen is added (for example, a screen with a consistent size and a smaller dot pitch is added), the terminal 102 may adjust the picture in a zooming manner; when the special-shaped screen is rotated, the terminal 102 may adjust the picture in a rotating manner. The terminal 102 may determine the picture adjustment information for the output picture in the output window corresponding to the special-shaped screen based on different picture adjustment modes.
The output window may be an output window in video playing software in the terminal 102. An initial output picture can be displayed in advance in an output window in the terminal 102 corresponding to the special-shaped screen, and the terminal 102 can determine the initial display picture information of the output window according to a similar principle. For example, in one embodiment, before receiving the form adjustment information of the shaped screen, the method further includes: receiving an input picture, inputting the input picture into an input window to obtain an original picture in the input window, and determining an output picture corresponding to the specification of the output window according to the picture content of the original picture in the input window.
In this embodiment, the special-shaped screen may be a special-shaped screen composed of a plurality of display screens, and the terminal 102 may generate an input window and an output window in video playing software in the terminal 102, where the input window is related to the picture content imported by the user, and may be a part of area or a whole area of the picture content, for example, may be used to display an original picture imported by the user; the output window can display the corresponding output picture, and the output window is related to the last displayed picture content of the display screen, that is, the output picture and the input picture can be similar pictures or equal pictures. For example, the area, size or shape of the output frame may be different from the frame area, frame size and frame shape of the input window, and the output frame and the input frame may be similar frames; the area, size or shape of the output picture can also be the same as the picture area, picture size or picture shape of the input window, and in this case, the output picture and the input picture can be equal pictures, that is, the picture contents of the output picture and the input picture can be the same. In addition, it should be noted that, in some embodiments, the output picture may also be determined according to the similarity between the original picture and the output picture. For example, the terminal 102 may determine, as an output picture in the output window, a picture whose similarity to the original picture in the input window is greater than or equal to a preset similarity threshold.
In some embodiments, the output window may also be used to display the distribution information of the plurality of display screens constituting the special-shaped screen, for example, for an LED display screen magic cube, the terminal 102 may display the planar development of each display screen constituting the LED display screen magic cube in the output window, so as to obtain the distribution information of the plurality of display screens constituting the special-shaped screen. After the terminal 102 obtains the distribution information of the plurality of display screens for forming the special-shaped screen, the distribution information of the plurality of sub-pictures can be determined based on the distribution information of the plurality of display screens.
The sub-pictures can be pictures displayed in the display screens forming the special-shaped screen, each sub-picture can be displayed in the output window, each sub-picture displays corresponding picture content, and the whole picture formed by the sub-pictures can be used as an output picture, so that the display picture of the special-shaped screen is obtained. Therefore, the terminal 102 may first determine distribution information of a plurality of sub-pictures and determine the picture content displayed in each sub-picture from the original picture, and the determining process may be that the terminal 102 randomly selects a picture corresponding to the shape and size of each display screen from the original picture as the sub-picture of each display screen. The terminal 102 may combine the plurality of sub-pictures according to the display order based on the distribution information of the plurality of sub-pictures to obtain a combined picture composed of the plurality of sub-pictures, where the combined picture may be an output picture in an output window, so that the terminal 102 may obtain a similarity between the combined picture and an original picture, and determine a picture to be mapped in a display screen corresponding to the plurality of sub-pictures based on the similarity between the combined picture and the original picture. So that the output window can display a picture similar to the original picture. That is, the terminal 102 may determine, after acquiring the original picture input by the user, an output picture similar to the input picture for the first time by using a similar principle.
Step S204, adjusting each endpoint corresponding to the output picture according to the picture adjustment information to obtain endpoint adjustment information.
The picture adjustment information may be the picture adjustment information of the output picture in the output window corresponding to the special-shaped screen, which is obtained by the terminal 102 after the special-shaped screen is subjected to the form adjustment. The shape of the output picture in the output window may be the same as the shape of the special-shaped screen, since the special-shaped screen is a polygon, the polygon may have a plurality of end points, and the picture adjustment information includes operations such as rotation, translation, and zooming, the terminal 102 may adjust each end point in the output picture in the output window according to the various kinds of picture adjustment information to obtain the end point adjustment information. The endpoint adjustment information may be implemented by an adjustment matrix corresponding to the picture adjustment information, and the adjustment matrix includes a scaling matrix, a translation matrix, a rotation matrix, and the like. That is, for each type of screen adjustment information, the terminal 102 may calculate each endpoint in the output screen using a corresponding adjustment matrix to obtain an adjusted endpoint, and the terminal 102 may obtain the endpoint adjustment information based on the adjustment information of multiple endpoints.
And step S206, slicing the original picture in the input window according to the endpoint adjustment information to obtain a picture to be displayed.
The endpoint adjustment information may be information for adjusting each endpoint of the output screen in the output screen. The to-be-displayed picture can be a picture displayed in the special-shaped screen, and the to-be-displayed picture can be a picture obtained after the adjustment requirement of the special-shaped screen is correspondingly adjusted. The requirements for adjusting the special-shaped screen include, but are not limited to, a translation adjustment of the screen when the special-shaped screen is repositioned, a zoom adjustment when the special-shaped screen is exchanged for another special-shaped screen (for example, the screen is exchanged for a screen with a consistent shape and a higher resolution) or a new special-shaped screen is added (for example, the screen is added with a consistent size and a smaller dot spacing), a rotation adjustment of the screen when the special-shaped screen is rotated, and the like. The original image and the output image may be provided with coordinate systems, and the endpoint adjustment information may include information such as coordinates of the adjusted endpoint. The coordinate system may be a coordinate system in a target rectangular region associated with the material in the original picture in the input window, and the size of the target rectangular region may be adjusted. The terminal 102 may use the uppermost edge of the target rectangular region as the positive half axis of the X-axis and the leftmost edge of the target rectangular region as the positive half axis of the Y-axis to obtain the position coordinates of all points of the target rectangular region, store all the position coordinates in the form of an array, and the terminal 102 corresponds a subscript to the position coordinates of each point, for example, corresponds (0,0) to 0. And in the output picture, a target rectangular area corresponding to the size of the actual special-shaped screen can be determined in the output picture in the same way, and a coordinate system is established in the target rectangular area to obtain the position coordinates of all points in the target rectangular area in the output picture and the subscript of each position coordinate point. Wherein the subscripts of the respective points in the output picture and the original picture may be identical. When determining the endpoint adjustment information, the terminal 102 may obtain the subscript corresponding to the clicked point in the output picture, and obtain the position coordinate corresponding to the subscript in the array of the position coordinates corresponding to the input window based on the subscript, thereby obtaining the position of the adjusted point corresponding to the output picture in the original picture, and further obtaining the endpoint adjustment information. After the terminal 102 acquires the endpoint adjustment information, a to-be-displayed picture can be determined in the original picture. For example, the terminal 102 may map the adjustment information of each endpoint to a corresponding position in the original screen through a corresponding linear matrix based on the endpoint adjustment information, so that the terminal 102 may obtain a plurality of pieces of coordinate information corresponding to the target rectangular region in the original screen based on linear matrix operations of the plurality of endpoints, and the terminal 102 may determine the screen to be displayed from the original screen based on the plurality of pieces of coordinate information.
And S208, displaying the picture to be displayed on the special-shaped screen after the form adjustment through the output window.
The to-be-displayed picture can be a picture determined from an original picture, and the to-be-displayed picture can be a picture obtained by correspondingly adjusting an output picture in an output window corresponding to the special-shaped screen based on the adjustment requirement of the special-shaped screen and then slicing the original picture based on the adjustment. The terminal 102 may display the to-be-displayed picture on the form-adjusted special-shaped screen through the output window. The picture to be displayed may be a picture obtained by slicing an original picture. For example, the irregular screen may be a single polygonal screen or an irregular screen formed by combining a plurality of display screens. For a single polygonal screen, the terminal 102 may segment the original picture after the adjustment to obtain a picture to be displayed; for the special-shaped screen obtained by combining a plurality of display screens, the terminal 102 can obtain the form adjustment information of each display screen forming the special-shaped screen, so that the picture adjustment condition of each display screen is determined based on the form adjustment information of each display screen, the terminal 102 can segment the picture from the original picture to obtain the picture to be displayed corresponding to each display screen, and the terminal 102 can determine the picture to be displayed corresponding to the special-shaped screen after the form adjustment based on the picture to be displayed which is adjusted based on the adjustment requirement of the plurality of display screens, and display the picture to be displayed on the special-shaped screen after the form adjustment.
In the method for displaying the special-shaped screen, the picture adjustment information of the output picture in the output window corresponding to the special-shaped screen is determined based on the received form adjustment information of the special-shaped screen, each endpoint corresponding to the output picture is adjusted according to the picture adjustment information to obtain the endpoint adjustment information, the picture to be displayed is determined in the original picture based on the endpoint adjustment information, and the picture to be displayed is displayed on the special-shaped screen after the form adjustment. Compared with the traditional mode of adjusting the display picture based on the number of edges of the plane to be played, the scheme determines the endpoint adjustment information of each endpoint based on the picture adjustment information of the output picture in the output window corresponding to the special-shaped screen when the special-shaped screen is subjected to the form adjustment, so that the picture adjustment can be performed in the original picture based on the endpoint adjustment information, repeated cutting based on the number of edges of the picture is not needed to search for a proper picture segmentation mode, the performance of video playing software is improved, and the efficiency of adjusting the display picture of the special-shaped screen when the special-shaped screen is changed is improved.
In one embodiment, as shown in fig. 3, fig. 3 is a flowchart illustrating a step of determining a to-be-displayed frame in one embodiment. Determining a picture to be displayed in an original picture according to the endpoint adjustment information, wherein the method comprises the following steps: step S302, a linear matrix used for representing the corresponding relation between an original picture and an output picture is obtained; step S304, obtaining a first coordinate of the adjusted endpoint according to the endpoint adjustment information; step S306, aiming at each adjusted endpoint, determining a second coordinate corresponding to the adjusted endpoint in the original picture according to the first coordinate and the linear matrix of the adjusted endpoint; and step S308, obtaining a to-be-displayed picture according to the second coordinate corresponding to the first coordinate of each adjusted endpoint in the original picture.
In this embodiment, the terminal 102 may determine the picture to be displayed from the original picture in a linear matrix manner. The endpoint adjustment information may be obtained by adjusting, by the terminal 102, each endpoint of the target rectangular region in the output picture in the output window corresponding to the special-shaped screen based on the form adjustment requirement of the special-shaped screen. The endpoint adjustment information may include coordinates for each adjusted endpoint in the output frame. Because a coordinate system is set in the target rectangular area in the picture in the output window corresponding to the original picture and the special-shaped screen, and the coordinate system can be the coordinate system in the target rectangular area associated with the material in the original picture set in the input window, the target rectangular area corresponding to the size of the actual special-shaped screen can be determined in the output picture in the same way in the output picture, and a coordinate system is generated in the target rectangular area, wherein the coordinates in the coordinate system are stored in an array form, each coordinate corresponds to a subscript, and the subscripts of each point in the output picture and the original picture can be consistent. The terminal 102 may first obtain a linear matrix representing a correspondence between an original picture and an output picture in an output window corresponding to the odd-shaped screen. The terminal 102 may further obtain the adjusted first coordinates of each endpoint from the endpoint adjustment information.
