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.

It can be understood that the LED screen rotation is a special display control method, and generally speaking, the LED screen is formed by splicing rectangular boxes with specific sizes, and the screen rotation is to rotate the rectangular boxes, but still output images at a viewing angle suitable for human beings. When the actual LED box is rotated, the corresponding displayed image will also be rotated, as shown in fig. 1a, the image displayed by the LED box before and after the rotation is schematic when the LED box is rotated but the displayed image is not adjusted, and as can be seen from the figure, after the LED box is rotated from the position shown in the left diagram of fig. 1a to the position shown in the right diagram of fig. 1a, the image displayed by the LED box after the rotation is not adjusted, the image shown in the right diagram of fig. 1a will be displayed by the LED box after the rotation. Therefore, in practical applications, after the actual LED box is rotated, the image displayed on the rotated LED box needs to be correspondingly adjusted, so that the image displayed on the rotated LED box is displayed in a forward direction, as shown in fig. 1b, when the image displayed on the rotated LED box is adjusted after the rotation of the LED box, the image displayed on the LED box before and after the rotation is a schematic diagram, and as can be seen from the figure, after the LED box is rotated from the position shown in the left diagram of fig. 1b to the position shown in the right diagram of fig. 1b, if the image displayed on the rotated LED box is adjusted, the rotated LED box displays the image displayed in the forward direction as shown in the right diagram of fig. 1 b.

In one embodiment, as shown in fig. 2, a virtual LED box orientation determining method is provided, and this embodiment is illustrated by applying the method to a terminal, wherein the terminal may be, but is not limited to, various personal computers, notebook computers and tablet computers. In this embodiment, the method includes the steps of:

step S202, displaying a virtual LED screen body in a display page; the virtual LED screen body is obtained by splicing a plurality of virtual LED box bodies.

The terminal is provided with upper computer software, the upper computer software is used for visually displaying actual LED boxes, virtual LED boxes can be added into the upper computer software, the virtual LED boxes are numbered, the virtual LED display screens are spliced according to the numbering relation, the upper computer software can also issue parameters related to the LED boxes to receiving cards connected with the LED boxes and can be used for controlling the image output display of each LED box.

Specifically, the number of LED boxes constituting the actual LED screen may be obtained in advance, a plurality of virtual LED boxes corresponding to the number are added to the upper computer software, and a connection relationship between the added virtual LED boxes is established according to a physical connection relationship between the LED boxes constituting the actual LED screen, so that a virtual LED screen body corresponding to the actual LED screen is obtained.

Step S204, responding to the designated angle setting operation aiming at the target virtual LED box body in the plurality of virtual LED box bodies, and adding a first mark pattern to the vertex of the designated angle in the display page; the designated angle is any angle of the virtual LED box body.

The first marking pattern may be a dot (solid or hollow), a figure (e.g., circle, square, etc.), or other patterns with marking function.

The target virtual LED box body can be any one of the virtual LED box bodies forming the virtual LED screen body, and it can be understood that if the whole virtual LED screen is rotated, the target virtual LED box body is all the virtual LED box bodies forming the virtual LED screen.

Specifically, before step S204, the method further includes receiving a click operation on the target virtual LED box, and in response to the click operation, displaying a markup page, where the markup page includes a box designation corner mark entry, and the box designation corner mark entry is used for displaying a plurality of designation corner selection entries when the box designation corner mark entry is in a trigger state. Receiving a selection operation for selecting an entry for any specified corner, and adding a first mark pattern to the position (such as a vertex) of the corresponding corner on the target virtual LED box in the display page. Since the LED box is generally in the form of a quadrangle, the designated corner selection entries may include an upper left selection entry, an upper right selection entry, a lower right selection entry, and an upper left selection entry.

For example, referring to fig. 3, fig. 3 is a schematic diagram of a designated corner setting operation on a target virtual LED box, as shown in the drawing, a box designated corner mark entry 302 is included on the mark page 30, when the box designated corner mark entry 302 is in a trigger state, an upper left corner selection entry, an upper right corner selection entry, a lower right corner selection entry and an upper left corner selection entry are displayed, in fig. 3, the selected designated corner is the upper left corner, and therefore, the terminal will add a first mark pattern to the vertex of the upper left corner of the target virtual LED box.

Referring to fig. 4a, a schematic diagram of the virtual LED screen body after the first mark pattern is added when the virtual LED screen is rotated in the whole screen, where the upper left corner of each virtual LED box in the diagram is a designated corner, and each virtual LED box is added with the first mark pattern such as a solid dot in an area 40 in the diagram.

In one embodiment, the location at which the first marker pattern is added may also be a location near the vertex of a specified angle of the target virtual LED box. By setting the position of the designated corner as a position close to the vertex of the designated corner, the problem that when the first mark patterns are added to two adjacent virtual LED boxes, the first mark patterns corresponding to the virtual LED boxes are difficult to accurately distinguish due to too close distance or even overlapping of the two first mark patterns can be avoided.

Step S206, receiving a rotation angle of the actual LED box body corresponding to the target virtual LED box body, and rotating the target virtual LED box body in the display page according to the rotation angle to obtain the rotated target virtual LED box body.

It can be understood that, in the present application, the orientation of the rotated actual LED box is determined, and therefore, when the actual LED corresponding to the target virtual LED box rotates, the target virtual LED box needs to be rotated, and if the actual LED corresponding to the target virtual LED box does not rotate, the target virtual LED box does not need to be rotated.

Specifically, when the actual LED box corresponding to the target virtual LED box rotates, the target virtual LED box may be rotated in the upper computer software in order to facilitate control of forward display of an image of the rotated actual LED box. More specifically, the terminal may receive a rotation angle and a rotation center, which are input by a user and are equal to the rotation angle of the actual LED box, and after the rotation angle and the rotation center are determined, the terminal controls the target virtual LED box to rotate around the rotation center by an angle equal to the received rotation angle, so as to obtain the rotated target virtual LED box.

And step S208, determining a new target position of the vertex of the designated angle on the rotated target virtual LED box body in the display page, and adding a second mark pattern based on the new target position.

Specifically, after the target virtual LED box is rotated, the position of the designated angle on the target virtual LED box is changed, so that a new target position of the vertex of the designated angle on the rotated target virtual LED box in the display page needs to be determined, and a second mark pattern is added based on the new target position, where the second mark pattern may be the same as the first mark pattern or different from the first mark pattern.

Further, after the second mark pattern is added, the terminal can also store related data such as the rotation angle, the rotation center, the position of the first mark pattern and the position of the second mark pattern of the target virtual LED box body in the transmitter, so that when other operators or current operators read back the data of the transmitter from the transmitter through other terminals, the current orientation of the target virtual LED box body can also be determined through the first mark pattern and the second mark pattern in the software interface of the upper computer.

Step S210, obtaining a relative position relationship between the first mark pattern and the second mark pattern, and determining the current orientation of the rotated target virtual LED box body according to the relative position relationship.

Specifically, after the adding of the first mark pattern of the target virtual LED box before rotation and the adding of the second mark pattern of the target virtual LED box after rotation are completed, the relative position relationship between the first mark pattern and the second mark pattern can be determined, and the current orientation of the target virtual LED box after rotation can be determined according to the relative position relationship.

Referring to fig. 4b, fig. 4b is a schematic diagram of the target virtual LED box before and after rotation in one embodiment, in which P0-P1-P2-P3 represents the target virtual LED box before rotation, P0 '-P1' -P2 '-P3' represents the target virtual LED box after rotation, pattern 42 represents a first mark pattern, and pattern 44 represents a second mark pattern, and it can be seen from the figure that the second mark pattern is on the left side of the first mark pattern, so that it can be determined that the target virtual LED box is rotated counterclockwise, and if the counterclockwise direction is the forward direction, the target virtual LED box is rotated by 45 degrees in combination with the rotation angle of the actual LED box by 45 degrees, so that the current direction of the target virtual LED box after rotation is a direction corresponding to an angle of 135 degrees.

In order to more conveniently determine the current orientation of the rotated target virtual LED box and improve the accuracy of the determination result, when the target virtual LED box is rotated, a rotation track of the target virtual LED box is generated, and a rotation direction is marked on the rotation track, for example, the rotation direction of the target virtual LED box can be represented by an arrow, and the current orientation of the rotated target virtual LED box is determined by combining the rotation track and the rotation direction of the target virtual LED box.

Further, in an embodiment, after step S210, the method further includes: and adjusting the display angle of the image to be displayed in the rotated target virtual LED box body according to the current orientation so that the image to be displayed is positively displayed in the rotated target virtual LED box body.

Specifically, after the current orientation of the rotated target virtual LED box body is determined, the image to be displayed of the target virtual LED box body can be adjusted according to the current orientation, and the image to be displayed of the target virtual LED box body can be visually rotated, so that the image to be displayed can be displayed in the rotated target virtual LED box body in the forward direction.

For example, in fig. 4b, the current orientation of the rotated target virtual LED box is a direction corresponding to an angle of 135 degrees, and therefore, the image to be displayed in the rotated target virtual LED box can be correspondingly rotated to the direction corresponding to the angle of 135 degrees, so that the image to be displayed is displayed in the rotated target virtual LED box in a forward direction.

In the method for determining the orientation of the virtual LED box body, the virtual LED screen body obtained by splicing a plurality of virtual LED box bodies is displayed in a display page; the method comprises the steps of responding to a designated angle setting operation aiming at a target virtual LED box body in a plurality of virtual LED box bodies, adding a first mark pattern to the vertex of the designated angle in a display page, rotating the target virtual LED box body in the display page according to the rotating angle when the rotating angle of an actual LED box body corresponding to the target virtual LED box body is received, obtaining the rotated target virtual LED box body, determining a new target position of the vertex of the designated angle on the rotated target virtual LED box body in the display page so as to add a second mark pattern based on the new target position, and finally determining the current orientation of the rotated target virtual LED box body according to the relative position relation between the first mark pattern and the second mark pattern. The method determines the orientation of each virtual LED box body through the mark patterns, and then the image required to be displayed by each rotated virtual LED box body can be quickly determined through the orientation of each virtual LED box body, so that the image is transmitted to the receiving card corresponding to the actual LED box body, the issuing efficiency of the program content can be improved, the normal display of the LED box body is prevented from being influenced, a screen assembler can intuitively and accurately determine the image displayed by the actual LED box body on physical connection, the screen adjusting time cost of the screen assembler is saved, and the working efficiency of the screen assembler is improved.

In an embodiment, the step S208 specifically includes: acquiring the size of a target virtual LED box body and the position of a rotating center in a display page; and determining a new target position of the vertex of the designated angle on the rotated target virtual LED box body in the display page according to the size of the target virtual LED box body, the position of the rotation center in the display page, the position of the first mark pattern in the display page and the rotation angle.

Further, in one embodiment, determining a new target position of the vertex of the designated angle on the rotated target virtual LED box in the display page further comprises: determining the initial corresponding position of the vertex of the designated angle on the rotated target virtual LED box body in the display page according to the size of the target virtual LED box body, the position of the rotation center in the display page, and the position and the rotation angle of the first mark pattern in the display page; and adjusting the initial corresponding position to the center direction of the target virtual LED box body to obtain a new target position.

Specifically, assuming that a point before rotation is M, a point after rotation is M ', the rotation angle is θ, and the rotation center is C, the position (x, y) of the point after rotation M' can be expressed by the following relational expression:

thus, when the upper left corner of the target LED box is designated as P0 (X0, Y0), the rotation angle is designated as P0

The width of the box body is recorded as width, and the height of the box body is recorded as height. When the upper left corner point confirms the position, remaining 3 summits when the box level was placed: top right corner point P1 (X1, Y1), bottom right corner point P2 (X2, Y2), bottom left corner point P3 (X3,y3) can be determined according to the width and height of the box body, and can be expressed by the following relation:

X1 = X0+width，Y1 = Y0

X2 = X0+width，Y2 = Y1+height

X3 = X0，Y3 = Y1+height

suppose 4 vertices are rotated counterclockwise (in the positive counterclockwise direction) by an angle around the top left corner point

If P0 '(X0', Y0 ')), P1' (X1 ', Y1'), P2 '(X2', Y2 '), P3' (X3 ', Y3') are obtained, the coordinate values of P0 ', P1', P2 'and P3' can be calculated by the following relations:

X0＇= X0，Y0＇= Y0

X1＇=（X1-X0）*cosθ-（Y1-Y0）*sinθ+ X0

Y1＇=（Y1-Y0）*cosθ-（X1-X0）*sinθ+ Y0

X2＇=（X2-X0）*cosθ-（Y2-Y0）*sinθ+ X0

Y2＇=（Y2-Y0）*cosθ-（X2-X0）*sinθ+ Y0

X3＇=（X3-X0）*cosθ-（Y3-Y0）*sinθ+ X0

Y3＇=（Y3-Y0）*cosθ-（X3-X0）*sinθ+ Y0

in addition, since trigonometric functions result in decimals, the calculated point locations require the addition of approximations, and if the X and Y values of P0 ', P1', P2 ', P3' differ from their nearest integer value by less than 0.000001, then it is default that X or Y is equal to the nearest integer value.

By the above example, when determining the size of the target virtual LED box, the position of the rotation center in the display page, the position of the first mark pattern in the display page, and the rotation angle, the initial corresponding position of the vertex of the designated angle on the rotated target virtual LED box in the display page may be calculated based on the principle of the above relational expression. After the initial corresponding position is obtained, in order to facilitate the determination of the orientation of the rotated target LED box, the initial corresponding position may be further adjusted toward the center direction of the target virtual LED box to obtain a new target position, and a second mark pattern is added based on the new target position.

In this embodiment, after the initial corresponding position of the vertex of the designated angle on the rotated target virtual LED box in the display page is determined by the size of the target virtual LED box, the position of the rotation center in the display page, and the position and the rotation angle of the first mark pattern in the display page, the initial corresponding position is adjusted toward the center direction of the target virtual LED box, so that convenience in determining the orientation of the rotated target virtual LED box and determination rate can be improved.

In an embodiment, the step of adjusting the initial corresponding position to obtain a new target position includes: acquiring length adjustment parameters for adjusting the initial corresponding positions; and moving the initial corresponding position to the center direction of the target virtual LED box body on the diagonal line of the rotated target virtual LED box body by the length adjustment parameter to obtain a new target position.

Wherein the length adjustment parameter may be 1/8 for the diagonal length.

Wherein the diagonal line for adjusting the initial corresponding position is a diagonal line passing through the vertex of the specified angle.

Specifically, for two adjacent virtual LED boxes, if the designated corner of the left virtual LED box is the upper right corner and the designated corner of the right virtual LED box is the upper left corner, when the two adjacent virtual LED boxes rotate with the same rotation center, rotation direction and rotation angle, after the rotation, if the second mark patterns are added to the top of the upper left corner of the right virtual LED box and the top of the upper right corner of the left virtual LED box respectively, the two mark patterns are close to each other, so that the problem of overlapping of the mark patterns is likely to occur, and at this time, it is difficult to accurately distinguish the second mark patterns corresponding to the virtual LED boxes. Therefore, in this embodiment, a method for adjusting the initial corresponding position to the center direction of the target virtual LED box by setting the length adjustment parameter and using the length adjustment parameter is proposed to solve the problem.

For example, referring to fig. 5, fig. 5 is a schematic diagram of a new target position on the rotated target virtual LED box in an embodiment, in which the vertex of the designated angle of the target virtual LED box is P0, then P0 ' may represent the initial corresponding position of the vertex of the designated angle on the rotated target virtual LED box in the display page, the distance between the points P0 ' -O represents the length adjustment parameter, two diagonal lines in the diagram, i.e., P0 ' P2 ' and P1 ' P3 ', since the designated angle is the angle corresponding to P0 ', and thus the diagonal line for adjusting the initial corresponding position P0 ' should be the diagonal line P0 ' P2 ' passing through the vertex P0 '. The initial corresponding position P0 ' is shifted 1/8 of the length of the diagonal line P0 ' P2 ' to the center direction of the target virtual LED box body on the diagonal line P0 ' P2 ' of the rotated target virtual LED box body, and a new target position shown by the point O in the figure is obtained.

In this embodiment, the initial corresponding position is moved to the center direction of the target virtual LED box on the diagonal of the rotated target virtual LED box by the length adjustment parameter to obtain a new target position, and the second mark pattern is added based on the new target position, so that the accuracy of the determination result of the current orientation of the rotated target virtual LED box can be improved.

In one embodiment, the step of adding the second mark pattern based on the new target position in step S208 includes: acquiring a first vertical distance and a second vertical distance of the new target position relative to two edges forming a designated angle respectively; determining a target vertical distance from the first vertical distance and the second vertical distance based on the magnitude relation of the first vertical distance and the second vertical distance; and drawing a marking circle according to the new target position and the target vertical distance to serve as a second marking pattern of the rotated target virtual LED box body.

Further, in one embodiment, the step of determining the target vertical distance from the first vertical distance and the second vertical distance includes: and determining the vertical distance with a smaller value in the first vertical distance and the second vertical distance as the target vertical distance.

Specifically, the two sides of the designated angle represent the two sides forming the designated angle on the rotated target virtual LED box, and after determining a smaller vertical distance from the first vertical distance and the second vertical distance based on the magnitude relationship between the first vertical distance and the second vertical distance, the method further includes: and acquiring a distance adjusting parameter, calculating a product of the distance adjusting parameter and the vertical distance with a smaller value as a target vertical distance, wherein the distance adjusting parameter can be 2/3, and then drawing a marking circle by taking the new target position as a circle center and the target vertical distance as a radius as a second marking pattern of the rotated target virtual LED box body. More specifically, before drawing the marker circle, it is also necessary to acquire the coordinates of the vertex of the specified corner, coordinates of another vertex forming a diagonal line adjusting the initial corresponding position together with the vertex of the specified corner, and determine the coordinates of the new target position in the display page based on the coordinates of the two vertices.

It can be understood that, when two adjacent virtual LED boxes rotate simultaneously with the same rotation center, rotation direction and rotation angle, and the designated angle of the left virtual LED box is the upper right corner, and the designated angle of the right virtual LED box is the upper left corner, if the second mark pattern is larger, the problem of overlapping the second mark pattern also easily occurs, therefore, in this embodiment, after a smaller vertical distance is determined from the first vertical distance and the second vertical distance, the smaller vertical distance is further adjusted by the distance adjustment parameter, and the pattern area of the second mark pattern is reduced, so as to solve the problem.

For example, referring to fig. 6, fig. 6 is a schematic diagram of a rotated target virtual LED box with a second mark pattern added thereto in an embodiment, in which P0 ' represents an initial corresponding position of a vertex of a specified angle on the rotated target virtual LED box in a display page, point O represents a new target position obtained after adjusting P0 ', two sides forming the specified angle are P0 ' P1 ' and P0 ' P3 ', respectively, a first vertical distance and a second vertical distance of the new target position with respect to the two sides forming the specified angle are OB and OC, respectively, and if the angle P2 ' P0 ' P3 ' is β, lengths of the first vertical distance OB and the second vertical distance OC can be represented by a relational expression:

OB=P0＇O*cosβ，OC=P0＇O*sinβ

as can be seen from the trigonometric function formula, when β =45 °, sin β = cos β, OB = OC; when 90 ° > β >45 °, sin β > cos β, then OB > OC; when 45 ° > β >0 °, sin β < cos β, then OB < OC. In fig. 6, β >45 °, so OB > OC is present, and therefore 2/3 of OC length is taken as the target vertical distance, so that a marking circle as shown in the figure can be drawn with O point as the center and 2/3 of OC length as the radius as the second marking pattern of the rotated target virtual LED box P0 'P1' P2 'P3'.

The coordinates of the new target position O point, i.e. the coordinates of the center of the marking circle, can be determined by using the similarity of the trigonometric functions. For example, in FIG. 6, right triangles P0 'P2' N are constructed, with angle P0 'NP 2' being right angles, and then a perpendicular OA from point O to segment P0 'N is made, creating similar triangles P0' OA and P0 'P2' N. If the center of the drawing circle is O (Xo 0, Yo 0), the coordinates of the center of the circle O can be expressed as:

Xo0 = 1/8*（X2＇-X0＇） +X0＇，Yo0 = 1/8*（Y2＇-Y0＇）+Y0＇

similarly, if other angles are taken as the designated angles, the coordinates of the corresponding circle center can be determined, and the marking circle can be drawn.

In this embodiment, after the smaller vertical distance is determined from the new target position in the first vertical distance and the second vertical distance respectively corresponding to the two sides forming the designated angle, the smaller vertical distance is adjusted by the distance adjustment parameter, so that the problem that the second mark pattern is determined incorrectly due to the overlapping of the second mark patterns when two adjacent virtual LED boxes rotate simultaneously is further avoided, and therefore, the accuracy of the determination result of the current orientation of the rotated target virtual LED box is improved.

In another embodiment, as shown in fig. 7, a method for determining the orientation of a virtual LED box is provided, and in this embodiment, the method includes the following steps:

step S702, displaying a virtual LED screen body in a display page; the virtual LED screen body is obtained by splicing a plurality of virtual LED box bodies;

step S704, responding to the designated angle setting operation aiming at the target virtual LED box body in the plurality of virtual LED box bodies, and adding a first mark pattern to the vertex of the designated angle in the display page; the designated angle is any angle of the virtual LED box body;

step S706, receiving a rotation angle of the actual LED box body corresponding to the target virtual LED box body, and rotating the target virtual LED box body in the display page according to the rotation angle to obtain the rotated target virtual LED box body;

step S708, acquiring the size of the target virtual LED box body and the position of the rotation center in the display page; determining the initial corresponding position of the vertex of the designated angle on the rotated target virtual LED box body in the display page according to the size of the target virtual LED box body, the position of the rotation center in the display page, and the position and the rotation angle of the first mark pattern in the display page;

step S710, acquiring length adjustment parameters for adjusting the initial corresponding position, and moving the length adjustment parameters of the initial corresponding position on the diagonal line of the rotated target virtual LED box body towards the center direction of the target virtual LED box body to obtain a new target position;

step S712, acquiring a first vertical distance and a second vertical distance of the new target position with respect to two edges forming the designated angle, respectively;

step S714, determining a target vertical distance from the first vertical distance and the second vertical distance based on the magnitude relation of the first vertical distance and the second vertical distance;

step S716, drawing a marking circle according to the new target position and the target vertical distance, wherein the marking circle is used as a second marking pattern of the rotated target virtual LED box body;

step S718, obtaining a relative position relationship between the first mark pattern and the second mark pattern, and determining the current orientation of the rotated target virtual LED box according to the relative position relationship.

In this embodiment, when the screen output of LED box is controlled through host computer software, orientation before the virtual LED box is rotated can be visually recorded through orientation prompt of the virtual LED box in the host computer software after the box is rotated, the current orientation of the virtual LED box after the rotation is visually determined, the output image of the LED box is visually rotated, the output effect can be visually seen on the screen, and therefore a user who assembles the actual LED screen box can conveniently maintain the LED screen.
