Detailed Description
Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and 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 interactive effects may be provided to the user along with music, and in particular, images, animations, colors, etc. may be displayed on output display devices arranged in the venue, typically on both sides of a stage. In this way, a particular visual effect may be presented in the performance venue during performance.
However, the scene of the performance is complicated, the emotion and the explosion point of the audience cannot be completely grasped in advance, and the temporary music effect presentation cannot be realized. Moreover, because the relevance between the presentation of the visual effect and the user is low, the interactive experience effect obtained by the user is poor.
In view of the foregoing technical problems, an idea of the present application is to provide a display control method, a display control apparatus, a display system, and an electronic device for distributed display units, where position information and state information of a plurality of distributed display units are first obtained, then a display image is generated based on the position information and the state information, a display instruction for controlling each display unit of the plurality of distributed display units to display pixel points constituting the display image is generated, and finally the display instruction is sent to the plurality of distributed display units. Therefore, images can be generated based on the positions and the states of the display units and controlled to serve as pixel points to display the images, a better interactive visual effect can be provided for a user, and user experience is enhanced.
It should be noted that the above basic concept of the present application can be applied to various occasions where interactive visual effects need to be provided to users, including but not limited to large-scale performances, large-scale conferences and other activities. The venue for the event is not limited to an indoor venue, and may be an outdoor area such as a park.
Having described the general principles of the present application, various non-limiting embodiments of the present application will now be described 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 forming the display image; and S140, sending the display instruction to the plurality of distributed display units.
In step S110, position information and status information of a plurality of distributed display units are acquired. As described above, the display control method for distributed display units according to the embodiments of the present application may be used to provide interactive visual effects to users in large activities such as concerts, and thus, a plurality of distributed display units may correspond to respective seats within a performance 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 site.
Fig. 2 illustrates a schematic diagram of a distribution of display units per show venue seat according to an embodiment of the present application. As shown in fig. 2, a plurality of seats S are arranged in the performance site according to the overall shape of the venue and the position of the stage P, and the seats S are partitioned 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 to serve as the distributed display unit in the embodiment of the present application. In addition, during the performance, when the audience sits on the seat, the audience may carry various display devices that can be used for displaying, such as a fluorescent stick, a bracelet, an LED display board, and the like, or may be a smart phone carried by the user.
Therefore, in the display control method for a distributed display unit according to the 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 show venue, there may be areas such as hallways L, stands P, and other vacant areas where no seats are installed. In addition, in activities such as open-air shows, there are no fixed seats, but regional information for the activity, such as a particular region where the activity is held, may be obtained. In general, seats are installed in accordance with the shape of an area in a playground, for example, in an oval stadium as shown in fig. 2, seats are installed in accordance with the shape of an oval outer circumference. Furthermore, in the case of a fixed location, such as an open-air music festival event, it is also possible to obtain location information of a display unit, for example, a mobile phone of a user, thereby obtaining distribution information of the display unit.
Therefore, in the display control method for distributed display units 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 in which the plurality of distributed display units are arranged; acquiring distribution information of the plurality of distributed display units in the predetermined area; and obtaining position information of the plurality of distributed display units based on the area information and the distribution information.
In addition, in the case of fixed seating such as within a venue, it is possible that in an actual performance, there are no spectators on some seats. Therefore, in order to improve the visual effect, the influence of these voids should be considered also when generating an image.
Therefore, in the display control method for distributed display units according to the embodiment of the present application, acquiring the state information of the plurality of distributed display units includes: obtaining enabling information indicating whether the plurality of distributed display units are enabled.
Here, it can be understood by those skilled in the art that in the display control method for the distributed display unit according to the embodiment of the present application, the position information and the state information of the distributed display unit can be obtained in various ways. For example, the information of the distributed display unit can be collected in real time in an activity site through a mode such as local area network wireless communication, which is especially suitable for the situation that the distributed display unit is not fixedly arranged.
Furthermore, in a performance, for example, held in a venue, the relevant information may be obtained from a backend server holding the activity information. For example, for a particular venue hosting an event, the seat coordinate lattice data may be obtained from the backend server, thereby obtaining coordinate location information for the seats within the venue. And, based on the ticketing information of the ticketing server or the like, it is possible to determine which seats are sold/unsold, thereby obtaining the 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 distributed display units 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 a live actual display unit, rather than always displaying a fixed image. Moreover, based on the distribution of the distributed display units, especially the large number of distributed display units in a large-scale event, each display unit in the embodiment of the present application only displays the pixel points that constitute the display image, rather than displaying a complex pattern that is part of the image. For example, for a display device such as a display screen, a bracelet, or a mobile phone carried by a user, only a single-color pattern may be displayed, thereby stitching into a complete pattern based on the distribution of the display units. Even for display units such as three-color LEDs that can have varying display modes, they are part of the pixels of the displayed image and are not used to display complex patterns that can form part of the image.
In addition, the display image according to the embodiment of the present application may be dynamically generated based on the situation of the scene, for example, in a concert, dynamically changed according to music.
Therefore, 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 combination of pixels based on the location information.
In particular, a music tempo can be identified in real time in the live and converted into a predefined visual effect of images/graphics/colors. The visual effect is displayed by using a full seat coordinate point as a 'canvas' through an LED display device on the seat coordinate point. Also, the display image may include animation, images, colors, and the like, which are 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 a video script generated automatically identifying song tempos and/or melodies. The video script comprises a graph, a video or a color matched according to the song, and can change, display/disappear or change in color brightness in real time according to the song.
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 distributed display units 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 distribution information of the display unit in terms of image details, thereby improving the display effect.
For example, at a large performance scene such as a concert, it is desirable to determine how well the automatically generated display image is rendered based on the on-site seat sales and venue seat layout. Based on basic pattern presentation tests (experimental tests) in a venue, it can be seen that a pattern consisting of a predetermined size of seat lattice is the smallest graphic unit that is easy to recognize visually. For example, for a typical indoor stadium sized performance venue, the size of the seat lattice is 4 × 4. In addition, in consideration of the actual presentation effect, the scene pattern and animation change are presented by the basic figure or color bar with the same color system or the same color. Therefore, whether the basic figure can be visually recognized by the user is judged by judging whether the coverage of the homochromatic system/homochromatic lattice is greater than or equal to the predetermined size of the lattice through the image frame or the animation static frame.
Furthermore, depending on the frame rate of the images generated, when a set of 24 frames/second static image sequence charts within 5 seconds changes in the venue, whether the passing through hollowed-out area (including the empty seats, and the unmanned seats, which are typically entrances or reserved explosion-proof areas) exceeds a predetermined threshold, e.g., 30%, will affect the basic image presentation.
Therefore, 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 size of a homochromatic system or a homochromatic pixel lattice in the candidate image is greater than or equal to a predetermined pixel lattice; and setting the candidate image as the display image in response to the size of a homogeneous or homogeneous pixel dot matrix in the candidate image being greater than or equal to a predetermined pixel dot matrix.
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 display unit and the blank pixel points which are not started in the candidate image exceeds the hollow threshold 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 display unit and the blank pixel points which are not started in the candidate image does not exceed the hollow threshold.
Fig. 3 illustrates a flow diagram of a presentation scene image generation according to an embodiment of the application. As shown in fig. 3, in step S210, sound data is collected in real time; in step S220, loading the collected sound data into an image server; in step S230, recognizing a rhythm/melody of the sound data; in step S240, candidate images conforming to the music style, such as graphics, video, color, etc., are selected; in step S250, determining whether the size of the homochromatic system or homochromatic 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 homochromatic or homochromatic pixel lattice in the candidate image is greater than or equal to a lattice size threshold, determining whether the sum of inactive display units and blank pixels in the candidate image exceeds a hollow-out threshold of the candidate image further based on the status information and the location information of the plurality of distributed display units; in step S270, in response to determining in step S260 that the sum of the display unit and the blank pixel that are not enabled in the candidate image does not exceed the hollow 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 homochromatic system or homochromatic pixel lattice in the candidate image is smaller than the lattice size threshold, or it is determined in step S270 that the sum of the inactive display units and the blank pixels in the candidate image exceeds the hollow threshold of the candidate image, the process exits.
In step S130, a display instruction for controlling each of the plurality of distributed display units to display pixel points 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 pixel points.
In step S140, the display instruction is sent to the plurality of distributed display units.
Finally, display instructions are sent to the plurality of distributed display units, for example, by live RF broadcast signals, so that the display units exhibit visual interactive effects.
