Detailed Description
Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application and not all of the embodiments of the present application, and it should be understood that the present application is not limited by the example embodiments described herein.
Summary of the application
As described above, in the field of large activities, visual effects may be provided to a user through a display device such as a Light Emitting Diode (LED) display. For example, at a concert venue, LED interaction effects may be provided to the user with music, and in particular, images, animations, colors, etc. may be displayed on output display devices disposed in the venue, typically on both sides of the stage. In this way, a particular visual effect may be presented in the venue during the performance.
However, the live situation of the performance is complicated, the emotion and the burst point of the audience cannot be grasped completely in advance, and temporary music effect presentation cannot be realized. Moreover, the relevance between the presentation of the visual effect and the user is low, so that the interactive experience effect obtained by the user is poor.
In view of the foregoing technical problems, it is an idea of the present application to provide a display control method, a display control device, a display system, and an electronic apparatus for a distributed display unit, first obtain position information and status information of a plurality of distributed display units, then generate a display image based on the position information and the status information, and generate a display instruction for controlling each display unit of the plurality of distributed display units to display pixels composing the display image, and finally send the display instruction to the plurality of distributed display units. In this way, by generating images based on the positions and states of the plurality of display units and controlling the images to be displayed as pixels, a better interactive visual effect can be provided for the user, thereby enhancing the user experience.
It should be noted that the above basic concepts of the present application may be applied to various occasions where an interactive visual effect needs to be provided to a user, including, but not limited to, activities such as a large performance, a large conference, and the like. The place where the event is held is not limited to an indoor venue, but may be an outdoor area such as a park.
Having described the basic principles of the present application, various non-limiting embodiments of the present application will now be described in detail with reference to the accompanying drawings.
Exemplary System
Fig. 1 illustrates a flowchart of a display control method for a distributed display unit according to an embodiment of the present application.
As shown in fig. 1, a display control method for a distributed display unit according to an embodiment of the present application includes: s110, acquiring position information and state information of a plurality of distributed display units; s120, generating a display image based on the position information and the state information; s130, generating a display instruction for controlling each display unit in the plurality of distributed display units to display pixel points composing the display image; and S140, sending the display instruction to the distributed display units.
In step S110, position information and state information of a plurality of distributed display units are acquired. As described above, the display control method for a distributed display unit according to the embodiments of the present application may be used to provide interactive visual effects to a user in a large-scale event such as a concert, and thus, a plurality of distributed display units may correspond to respective seats within a venue.
That is, in the display control method for a distributed display unit according to the embodiment of the present application, the distributed display unit is a display unit provided on each seat within a performance venue.
Fig. 2 illustrates a schematic diagram of display unit distribution according to a venue seat being developed according to an embodiment of the present application. As shown in fig. 2, in the performance venue, a plurality of seats S are arranged in accordance with the overall shape of the venue and the position of the stage P, and the seats S are separated by a walkway L. Accordingly, in the display control method for a distributed display unit according to the embodiment of the present application, one display screen may be provided on each seat, which serves as the distributed display unit in the embodiment of the present application. In addition, during the performance, when the spectator sits on the seat, the spectator may carry various display devices that may be used for display, such as a fluorescent wand, a bracelet, an LED display board, etc., and of course may also be a smart phone carried by the user, etc.
Thus, in a display control method for a distributed display unit according to an embodiment of the present application, the display unit includes a display screen mounted on the seat or a display device carried by a viewer on the seat.
Also, with continued reference to fig. 2, in a predetermined area such as a venue, there may be areas such as aisle L, stand P, and other blank areas where seats are not installed. In addition, in an event such as an open-air performance, there is no fixed seat, but area information of the event, such as a specific area where the event is held, can be obtained. In general, seats are provided in a region shape in a venue, for example, in an elliptical venue as shown in fig. 2, and are provided in an outer peripheral shape of an ellipse. Furthermore, in the case of a fixed location, such as an outdoor music festival activity, the location information of the display unit, for example, the user's mobile phone, can also be obtained, thereby obtaining the distribution information of the display unit.
Therefore, in the display control method for a distributed display unit according to the embodiment of the present application, acquiring the position information of the plurality of distributed display units includes: acquiring area information of a predetermined area provided with the plurality of distributed display units; acquiring distribution information of the plurality of distributed display units in the preset area; and obtaining positional information of the plurality of distributed display units based on the area information and the distribution information.
In addition, in the case of fixedly-located seats, such as within a venue, it is possible that some seats may not have spectators in the actual performance. Thus, in order to enhance the visual effect, the influence of these voids should also be considered in generating the image.
Thus, in the display control method for a distributed display unit according to an embodiment of the present application, acquiring the state information of the plurality of distributed display units includes: enabling information indicating whether the plurality of distributed display units are enabled is obtained.
Here, it is understood by those skilled in the art that in the display control method for a distributed display unit according to the embodiment of the present application, the position information and the state information of the distributed display unit may be obtained in various ways. For example, the information of the distributed display units may be collected in real time at the active site, such as by wireless communication over a local area network, which is particularly applicable in the case of non-stationary settings of the distributed display units.
In addition, in a performance held in a venue, for example, the relevant information can be obtained from a background server that holds the activity information. For example, for a particular venue hosting an event, seat coordinate lattice data may be obtained from a background server to obtain coordinate location information for seats within the venue. And, based on ticketing information of a ticketing server or the like, it is possible to determine which seats have been sold/unsold, thereby obtaining enabling information of the display unit.
In step S120, a display image is generated based on the position information and the state information.
As described above, in the display control method for a distributed display unit according to the embodiment of the present application, in order to obtain an enhanced interactive visual effect, a display image is generated according to position information and state information of an actual display unit on site, instead of always displaying a fixed image. Moreover, based on the distribution situation of the distributed display units, especially the large number of distributed display units in a large-scale activity, each display unit in the embodiment of the present application displays only the pixel points that constitute the display image, not the complex pattern that is a part of the image. For example, for a display screen, a bracelet, or a mobile phone carried by a user, or the like, only a single-color pattern may be displayed so as to splice into a complete pattern based on the distribution of display units. Even for a display unit such as a three-color LED that can have a variable display mode, it is a component of the pixel points of the display image, not for displaying a complex pattern that can constitute a part of the image.
In addition, the display image according to the embodiment of the present application may be dynamically generated based on the live situation, for example, in a concert, dynamically changed according to music.
Thus, in the display control method for a distributed display unit according to the embodiment of the present application, generating a display image based on the position information and the state information includes: acquiring real-time sound data; and generating the display image based on the real-time sound data, the display image including a pixel point combination based on the position information.
In particular, the music tempo may be identified in real-time on site and converted into a predefined visual effect of images/graphics/colors. The visual effect is displayed by an LED display device on the seat coordinate points with the full-field seat coordinate points as canvas. And, the display image may include an animation, an image, a color, etc. displayed and changed following the music tempo.
Thus, for a performance scene such as a concert, a song may be imported in real-time and the song tempo and/or melody automatically identified to generate a video script. The video script includes graphics, video, or colors that match according to songs, and can change, display/disappear, or change in color darkness according to songs in real time.
That is, in the display control method for a distributed display unit according to the embodiment of the present application, generating the display image based on the real-time sound data includes: identifying rhythm and/or melody information of the real-time sound data; and generating a video script based on the rhythm and/or melody information.
As described above, since the display control method for a distributed display unit according to the embodiment of the present application is preferably used to provide interactive visual effects to users in a large-scale scene such as a large-scale event, the generated display image also needs to be optimized in consideration of specific requirements in the scene. Specifically, the display image needs to be optimized with respect to the distribution information of the display unit in terms of image details, so that the display effect is improved.
For example, at a large performance venue such as a concert, it is desirable to determine how well the automatically generated display image is presented based on the venue's seat sales situation and venue seating layout. Based on a basic graphic presentation test (experimental test) in a venue, it can be seen that a graphic composed of a seat lattice of a predetermined size is the smallest graphic unit that is easily recognized by the vision. For example, for a typical stadium size room stadium, the size of the seat lattice is 4 x 4. And, in view of the actual rendering effect, the scene pattern and animation changes are rendered in substantially the same color system or the same color base pattern or color band. Therefore, whether the coverage of the same color system/the same color lattice is larger than or equal to the preset size of the lattice is judged through the image frame or the animation static frame, and whether the basic graph can be visually identified by a user is judged.
Furthermore, depending on the frame rate of the generated images, when a set of static image sequence diagrams of 24 frames/second within 5 seconds is changed in a venue, whether the passing open area (including empty seats, and typically unmanned seats of an access port or reserved explosion proof area) exceeds a predetermined threshold, for example, 30% will affect the basic graphic presentation.
Thus, in a display control method for a distributed display unit according to an embodiment of the present application, generating the display image based on the real-time sound data includes: acquiring a candidate image based on the real-time sound data; determining whether the size of a homochromatic system or a homochromatic pixel lattice in the candidate image is larger than or equal to a preset pixel lattice; and setting the candidate image as the display image in response to the size of the same-color system or the same-color pixel lattice in the candidate image being greater than or equal to a predetermined pixel lattice.
Further, in the display control method for a distributed display unit according to an embodiment of the present application, generating the display image based on the real-time sound data includes: acquiring a candidate image based on the real-time sound data; determining whether the sum of the non-activated display unit and the blank pixel point in the candidate image exceeds a hollowed-out threshold value of the candidate image or not based on the state information and the position information; and setting the candidate image as the display image in response to determining that the sum of the non-enabled display unit and the blank pixel point in the candidate image does not exceed the hollowed-out threshold.
Fig. 3 illustrates a flowchart of a show live image generation according to an embodiment of the present application. As shown in fig. 3, in step S210, sound data is collected in real time; in step S220, the collected sound data is loaded into an image server; at step S230, identifying a rhythm/melody of the sound data; in step S240, candidate images conforming to the music style are selected, which may be graphics, video, colors, etc., for example; in step S250, it is determined whether the size of the same color system or the same color pixel lattice in the candidate image is greater than or equal to a lattice size threshold; in step S260, in response to determining in step S250 that the size of the co-color system or co-color pixel dot matrix in the candidate image is greater than or equal to a dot matrix size threshold, determining whether a sum of non-enabled display units and blank pixel dots in the candidate image exceeds a hollowed-out threshold of the candidate image further based on the state information and the position information of the plurality of distributed display units; in step S270, in response to determining in step S260 that the sum of the non-enabled display unit and the blank pixel point in the candidate image does not exceed the hollowed-out threshold of the candidate image, the candidate image is set as a display image. In addition, if it is determined in step S260 that the size of the same-color system or the same-color pixel dot matrix in the candidate image is smaller than the dot matrix size threshold, or it is determined in step S270 that the sum of the non-enabled display unit and the blank pixel dot in the candidate image exceeds the hollowed-out threshold of the candidate image, the flow is exited.
In step S130, a display instruction for controlling each of the plurality of distributed display units to display pixels constituting the display image is generated.
That is, based on the generated display image and the related information of the distributed display unit, a display instruction is generated to control the display unit to display a pixel point.
In step S140, the display instruction is sent to the plurality of distributed display units.
Finally, a display instruction is sent to the plurality of distributed display units, for example, through an RF broadcast signal on site, so that the display units exhibit a visual interaction effect.
