Description

Display method and device of special-shaped display screen, storage medium and processor

Technical Field

The invention relates to the field of display control of LED display screens, in particular to a display method and device of a special-shaped display screen, a storage medium and a processor.

Background

The most common LED display screen is in a planar rectangular shape, and the lamp points are also in a regular row and column arrangement mode. The LED display screen corresponds to a rectangular signal source to be displayed, and due to point-to-point, pixel coordinates of the rectangular signal source corresponding to a lamp point are easy to calculate, and the problem of precision of coordinate conversion does not exist. On the basis of a conventional rectangular LED display screen, a non-rectangular special-shaped LED display screen can be formed, as shown in FIG. 1, the LED display screen is still in a rectangular regular row-column arrangement mode, only a part of light points are not arranged in the rectangular regular row-column arrangement mode, as shown in a black solid block on the right side of FIG. 1, namely, the LED display screen does not exist physically. The special-shaped LED display screen is basically consistent with a rectangular LED display screen in the point screen method.

The other type of special-shaped LED display screen has another regularity in the physical arrangement of the light points, that is, the light points are arranged according to a certain nonlinear curve, and the actual physical characteristic is not necessarily a plane, as shown in fig. 2, the physical arrangement of the light points is a sector. Because the lamp points of the display screen are physically distributed to the pixel points of the rectangular signal source and the point-to-point result is not completely achieved, the process of determining the coordinates is more complex compared with the conventional situation and the precision is lower.

In view of the above problems, no effective solution has been proposed.

In accordance with an embodiment of the present invention, there is provided a display method based on a shaped display screen, it should be noted that the steps shown in the flowchart of the figure may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that here.

The special-shaped display screen is composed of at least one layer of sub-screen, each layer of sub-screen is composed of at least one box body, each box body comprises at least one lamp panel, and the physical arrangement of lamp points on the lamp panels is arc-shaped. Under the condition that the special-shaped display screen comprises a plurality of lamp panels, the shapes and the sizes of the lamp panels are the same. Optionally, the light points of each lamp panel may be arranged in a manner as shown in fig. 2, and at this time, the light points on the lamp panel and the pixel points on the rectangular signal source image are not point-to-point.

In an optional embodiment, the special-shaped display screen can be composed of a plurality of fan-shaped lamp panels, the fan-shaped lamp panels can be spliced into a larger fan shape or a larger circular ring shape to obtain the fan-shaped or circular ring-shaped special-shaped display screen, the fan-shaped lamp panels can also be spliced into a watermelon peel shape, namely, the shape of the spherical shape after being split along the longitude line is not limited to the shape.

Fig. 3 is a display method based on a special-shaped display screen according to an embodiment of the present invention, as shown in fig. 3, the method includes the following steps:

step S302, code table information and a reference point of the lamp panel are obtained, wherein the code table information is used for representing arrangement information of lamp points on the lamp panel, the reference point is used for representing the position relation of a circular arc-shaped rotation center relative to a signal source image, and the shape of the signal source image is rectangular.

The code table information in the above steps may be a row column snapshot point information table of the lamp panel, which records which lamp points actually exist or do not exist in the whole lamp panel, and also includes information such as data group, channel number, scanning number, and the like.

Because the lamp point physics on the lamp plate is arranged and is arc-shaped, arc-shaped has a centre of a circle, also, every lamp plate all corresponds a centre of a circle (foretell rotation center promptly), and the position of this centre of a circle has decided the position of lamp plate, consequently, can confirm the position of every lamp point in the lamp plate through the position of this centre of a circle. In the above steps, a coordinate system may be established on the signal source image, and the lower left corner or the upper right corner of the signal source image may be used as a coordinate origin, but is not limited thereto, and then the coordinates of the reference point in the signal source image are calculated according to the position of the display image corresponding to the lamp panel relative to the signal source image. For example, a coordinate system is established by taking the lower left corner of the signal source image as the origin of coordinates, the display image corresponding to the lamp panel is located at the lower left corner, the reference point is located at the upper left side of the signal source image coordinate system, the transverse distance from the origin of coordinates is x, the longitudinal distance of coordinates is y, and the coordinates of the reference point are (x, y).

The signal source image in the above steps may be a picture to be displayed, an image frame in a video, but is not limited thereto.

And step S304, calculating relative coordinates of the lamp panel based on the code table information and the reference points, wherein the relative coordinates of the lamp panel are used for representing the position relation of the display image corresponding to the lamp points on the lamp panel relative to the original point of the signal source image.

After the lamp panels are manufactured, the positions of all radian rows in the lamp panels are fixed relative to the reference points, therefore, in the steps, the relative coordinates of each lamp panel can be determined by using the code table information of the lamp panels according to the acquired reference points corresponding to the lamp panels, and the relative coordinates of any one lamp panel can be obtained through rotation calculation of the lamp panel according to a certain angle in sequence, so that the calculated amount is reduced.

And S306, calculating absolute coordinates of the lamp panel based on the relative coordinates of the lamp panel, wherein the absolute coordinates of the lamp panel are used for representing the position relation of a display image corresponding to the lamp points on the lamp panel relative to the original point of the special-shaped display screen.

In the above steps, a coordinate system may be established in the special-shaped display screen, and the lower left corner or the upper right corner of the circumscribed rectangle of the special-shaped display screen may be used as the origin of the special-shaped display screen.

In an optional embodiment, when the special-shaped display screen is composed of at least one box body, and each box body comprises a plurality of lamp panels, coordinate conversion can be performed according to the calculated relative coordinates of the lamp panels, the absolute coordinates of the lamp panels are calculated, and then the absolute coordinates of the box body are calculated, or the relative coordinates of the box body can be directly calculated according to the relative coordinates of all the lamp panels contained in each box body, and then the absolute coordinates of the box body are calculated through coordinate conversion.

And S308, generating routing table information of the special-shaped display screen based on the absolute coordinates of the lamp panel.

In the above steps, the absolute coordinates of each lamp panel on the special-shaped display screen can be converted into routing table information of the special-shaped display screen, which can be realized by adopting a routing table information generation scheme in the related art, and the invention is not particularly limited to this.

In the embodiment of the invention, for the special-shaped display screen composed of a plurality of lamp panels with the same shape and size, the physical arrangement of the lamp points on the lamp panels is in a circular arc shape, the display method of the special-shaped display screen is realized by acquiring the code table information and the reference points of the lamp panels, calculating the relative coordinates of the lamp panels based on the code table information and the reference points, calculating the absolute coordinates of the lamp panels based on the relative coordinates of the lamp panels, and generating the routing table information of the special-shaped display screen based on the absolute coordinates of the lamp panels. It is easy to notice that, because the relative coordinate of the lamp panel is calculated based on the code table information and the reference point, and the code table information and the reference point are fixed and unchangeable, the determination accuracy of the relative coordinate of the lamp panel is higher, in addition, the absolute coordinate of the lamp panel is directly obtained by the relative coordinate conversion, the whole coordinate conversion process is simple, thereby achieving the technical effects of improving the coordinate conversion accuracy and simplifying the processing process, and solving the technical problem of lower coordinate calculation accuracy when the special-shaped LED screen with the lamp points arranged in the arc shape displays the rectangular signal source in the related technology.

The special-shaped display screen in the above step is in a fan shape or a circular ring shape, and as shown in fig. 4, the special-shaped display screen displays a partial image in a rectangular signal source image.

Optionally, contain a plurality of lamp plates at special-shaped display screen, and under the same condition of the rotation center of a plurality of lamp plates, based on stopwatch information and reference point, calculate the relative coordinate of lamp plate and include: calculating relative coordinates of a target lamp panel based on target code list information and a target reference point of the target lamp panel, wherein the target lamp panel is any one of the plurality of lamp panels; and rotating the relative coordinates of the target lamp panel by taking the target reference point as an original point, and calculating to obtain the relative coordinates of other lamp panels.

The plurality of lamp panels in the above step may be all lamp panels included in each layer of sub-screen.

In the fan-shaped or annular special-shaped display screen, the plurality of fan-shaped lamp panels are spliced together, and the relative coordinates of different fan-shaped lamp panels have an incidence relation, so that the relative coordinates of the lamp panel can be calculated according to the code table information and the reference point corresponding to one lamp panel (namely the target lamp panel) in the steps, and then the relative coordinates of the lamp panel are rotated by taking the reference point corresponding to the lamp panel as an original point, so that the relative coordinates of other lamp panels are calculated.

Optionally, based on the target code table information and the target reference point of the target lamp panel, calculating the relative coordinate of the target lamp panel includes: calculating coordinates of a reference point on a target radian row in the target lamp panel based on the target code table information and a target reference point, wherein the reference point is a middle point on the current radian row, and the target radian row is any one radian row in the target lamp panel; rotating the coordinates of the reference points by taking the target reference points as the original points, and calculating to obtain the relative coordinates of each lamp point on the target radian row; and calculating to obtain the relative coordinates of the target lamp panel based on the relative coordinates of all lamp points on all radian rows in the target lamp panel.

For the light points on the same radian row, the difference between the relative coordinates is that the corresponding angles are different, so that in the above steps, the midpoint coordinate on the current radian row of the lamp panel, i.e. the coordinate of the reference point, can be calculated according to the reference point and the code table information corresponding to the target lamp panel, the coordinate of the reference point is taken as the origin point, the coordinate of the reference point is rotated, and the relative coordinate of each light point on the radian row is calculated. And performing the processing on other radian rows on the lamp panel to obtain the relative coordinates of each lamp point on the other radian rows, wherein the relative coordinates of each radian row of lamp points are the relative coordinates of the lamp panel.

It should be noted that the special-shaped display screen only includes one lamp panel, or the special-shaped display screen includes a plurality of layers of sub-screens, and each layer of sub-screen includes one lamp panel, so that each lamp panel can calculate the relative coordinate by using the above method.

After the lamp plate is manufactured, the position of each radian row in the lamp plate relative to the reference point and the corresponding fan-shaped angle are fixed, so that the distance between each radian row and the reference point can be directly calculated according to the code table information of the lamp plate to serve as the depth of each radian row. And calculating the coordinates of the reference point according to the depth of the radian row and the coordinates of the reference point. For example, if the reference point is (x, Y), and the Y depth of the arc row corresponding to the lamp panel is d, the reference point coordinate corresponding to the arc row is (x, Y + d).

In the above step, each radian row in each lamp panel may be processed in the same manner, and the specific processing flow is as follows: firstly, inquiring the code table information of the lamp panel, and calculating the number of lamp points on a target radian line. And under the condition that the number of the lamp points is even, the coordinates of the reference point are rotated anticlockwise and clockwise by taking the reference point as an origin, and the relative coordinates of each lamp point are obtained through calculation. For example, as shown in fig. 5, where P is a reference point, P 'is a reference point, d is a Y depth of a radian row corresponding to the lamp panel, and θ is a sector angle corresponding to the sector lamp panel, if the reference point is P (x, Y), the coordinate of the reference point P' point is (x, Y + d), the example radian row is 6 lamp points, and the 6 lamp points are sequentially calculated by clockwise rotating the P 'point by 5 θ/12, 3 θ/12, θ/12, counterclockwise rotating the P' point by θ/12, 3 θ/12, and 5 θ/12. And under the condition that the number of the lamp points is odd, taking the coordinates of the lamp points positioned at the central position of the radian row as the coordinates of the reference point, taking the reference point as an original point, carrying out anticlockwise rotation and clockwise rotation on the coordinates of the reference point, and calculating to obtain the relative coordinates of other lamp points on the radian row. For example, as shown in fig. 6, where P is a reference point, P ' is a reference point, d is a Y depth of a radian row corresponding to the lamp panel, and θ is a sector angle corresponding to the sector lamp panel, if the reference point is P (x, Y), the coordinate of the reference point P ' is (x, Y + d), the example radian row is 5 lamp points, where the coordinate of P ' is the coordinate of a middle lamp point, and the remaining 4 lamp points are calculated by clockwise rotating the P ' point by 4 θ/10, 2 θ/10, counterclockwise rotating the P ' point by 2 θ/10, and 4 θ/10.

Optionally, before calculating the absolute coordinates of the lamp panel based on the relative coordinates of the lamp panel, the method further includes: correcting the coordinates of the lamp panel relative to the coordinates of the lamp panel, and calculating the corrected coordinates of the lamp panel; performing precision processing on the corrected coordinates of the lamp panel, and calculating to obtain the processed coordinates of the lamp panel; and calculating absolute coordinates of the lamp panel based on the processed coordinates of the lamp panel.

In the above steps, the relative coordinates of each lamp panel in the lamp box can be corrected according to a coordinate correction algorithm, the corrected coordinates are obtained through calculation, the corrected coordinates are subjected to precision processing, the floating point type coordinates are converted into integer type coordinates, the processed coordinates are obtained through calculation, the processed coordinates of all the lamp panels are subjected to combined processing, the relative coordinates of the special-shaped display screen are obtained through calculation, and finally the absolute coordinates of the special-shaped display screen are obtained through coordinate conversion.

The information of the first rectangular frame in the above steps may be circumscribed rectangle information of the fan-shaped lamp panel, and the correction value may be a pixel correction value.

In an alternative embodiment, the whole coordinate correction process is shown in fig. 7: inputting relative coordinates (floating point type) of a fan-shaped lamp panel to be corrected; then inputting pixel correction values v _ x and v _ y in the x and y directions, and calculating circumscribed rectangle information of the fan-shaped lamp panel; respectively taking y 'as yMin-yMax of the circumscribed rectangle, increasing the value from yMin to yMax by 1, obtaining a point Pij which is offset from the y-axis direction to be y' on each radian row on the lamp panel and has a difference smaller than a correction value v _ y, and correcting the y coordinate of the point to be y 'if | pij.y-y' | < v _ y; and respectively taking x 'as xMin-xMax of the circumscribed rectangle, gradually increasing the value from xMin to xMax by 1, obtaining a point Pij which is offset from the direction of the x axis by x' on each radian row on the lamp panel and has a difference smaller than a correction value v _ x, and correcting the x coordinate of the point to be x 'if | pij.x-x' | < v _ x, wherein 0< v _ x <1, and 0< v _ y < 1.

In the above step, for the special-shaped display screen, the processed relative coordinates of all lamp panels in the special-shaped display screen can be combined, so that the relative coordinates of the special-shaped display screen can be obtained through calculation.

The information of the second rectangular frame in the above step may be obtained by using the prior art, such as Python opencv minarea extract (a method for generating a minimum circumscribed rectangle), but is not limited thereto, and the detailed implementation process is not repeated here. And performing coordinate conversion according to the relative coordinates of the special-shaped display screen and the information of the corresponding second rectangular frame, and calculating to obtain the absolute coordinates of the special-shaped display screen.

However, the floating point type is converted into the integer type which is actually needed by the precision processing module, so that the problem of secondary precision loss of other target lamp panels exists in the scheme, the actual display effect is poor, and the image skew and dislocation are serious.

In an optional embodiment, as shown in fig. 9, the floating point type relative coordinates of the reference lamp panel may be directly rotated to obtain the relative coordinates of the other lamp panels (i.e., the target lamp panel 1 to the target lamp panel N), and after coordinate correction and precision processing, the floating point type relative coordinates are converted into integer coordinates, and finally, combined processing is performed to obtain the relative coordinates of the box body.
