The huge image display scheme fused with the venue provided by the present application is specifically explained below with reference to the accompanying drawings.
As shown in fig. 2 and fig. 3, an embodiment of the present application discloses a huge image display system fused in a venue, which includes an image processing apparatus 100, a plurality of controllers 300, and a plurality of single-point light emitting apparatuses 410;
a plurality of image block areas 40 are arranged in the venue, a plurality of single-point light emitting devices 410 are arranged in each image block area 40, the single-point light emitting devices 410 in each image block area 40 are in communication connection with a controller 300, and one controller 300 at least controls the light emitting state of all the single-point light emitting devices 410 in one corresponding image block area 40;
the image processing apparatus 100 that acquires a target jumbo image and distributes screen data of the target jumbo image to the controller 300;
the controller 300 receives the picture data of the target jumbo image, and acquires the picture data of the target area according to the position of the corresponding image block area 40; acquiring the positions of all the single-point light-emitting devices 410 in the corresponding image block area 40, and controlling the light-emitting states of the single-point light-emitting devices in the corresponding positions according to the picture data of the target area; the single-point light emitting devices 410 of the plurality of image block areas 40 collectively complete the display of the target jumbo image.
In a general venue, a playing field or a performance field is arranged in a central area, and audience areas arranged in steps are arranged around the center area. The audience may be divided into east, west, south and north audience areas by orientation. The image block area 40 may be obtained by dividing all the audience areas in the venue, may be obtained by dividing one of the audience areas, or may be obtained by dividing a partial area in one of the audience areas. It is understood that, according to the requirement, the venue may also be divided into a plurality of sub-picture areas, each sub-picture area includes a plurality of image block areas 40, and each sub-picture area may display a different target jumbo image.
In the following, a single sub-picture area is taken as an example — specifically, a viewer area on one side is divided to obtain a plurality of image block areas 40, and the scheme of the present application is specifically described.
The image processing device 100 may be a smart device, a computer, a server, or a cloud with data processing capability. A description will be given below of a computer as the image processing apparatus 100. The image processing apparatus 100 may obtain the target jumbo image from the outside or in a self-generated manner. The target jumbo image is a screen desired to be displayed by the jumbo image display system.
Each controller 300 controls the light emitting operation of the single point light emitting device 410 within at least one image block area 40. Each image block area 40 corresponds to an area in the target jumbo image, i.e., the target area. The controller 300 needs to determine a target area in the target jumbo image corresponding to the image block area 40 according to the position of the image block area 40, and acquire picture data corresponding to the target area from the picture data of the target jumbo image.
In some embodiments, in order to facilitate the controller 300 to acquire the picture data of the corresponding target area, the controller 300 may have a one-to-one correspondence with the image block areas 40, and the controller 300 may store the position information of the corresponding image block area 40 and the corresponding target area. At this time, the controller 300 receives the frame data of the target jumbo image, and then captures the frame data corresponding to the target area.
The single-point light emitting device 410 in the image block area 40 is communicatively connected to the controller 300. The communication connection mode may be wired communication connection or wireless communication connection. After the controller 300 obtains the picture data corresponding to the target area, the single-point light emitting device 410 corresponding to the pixel point position is controlled to operate according to the position of the single-point light emitting device 410 in the image block area 40 and the picture data. Together, the single-point light emitting devices 410 in all of the image block areas 40 collectively display the content of the target jumbo image.
For a target jumbo image, a single-point light emitting device 410 can be regarded as a pixel point in the frame. For a target jumbo image, which may be a monochrome picture, each single-point light emitting device 410 need only emit light of one color. It also can be full-color picture, and is corresponding, and every single-point light emitting device can full-color luminous, including a plurality of sub-luminescence units, and every sub-luminescence unit can send the primary color light of a colour, and the luminous mixed light that forms single-point light emitting device of all sub-luminescence units, and through the different light combination of sub-luminescence unit, can realize that single-point light emitting device 410 carries out full-color and send out. Each of the single-point light emitting devices 410, for example, may include a red sub-light emitting unit, a green sub-light emitting unit, and a blue sub-light emitting unit.
The single-point light emitting device 410 may be a common light source device, such as a low-pressure discharge lamp including a neon lamp and a low-pressure sodium lamp, a high-pressure discharge lamp including a high-pressure sodium lamp, a high-pressure mercury lamp, and a metal halide lamp, or an electroluminescent light source including a Light Emitting Diode (LED) and an EL light emitting point. The single-point light emitting device 410 can emit light in full color, i.e., red, green, and blue LEDs are used as sub-light emitting units, and the scheme of the present application is described below as an example. When the single-point light emitting device 410 emits light in full color, the controller 300 controls not only the light emitting state of the single-point light emitting device 410 but also the light emitting color of the single-point light emitting device 410.
Each image block area 40 corresponds to a local area in the audience area. Within each image block area 40, a plurality of single-point light emitting devices 410 are disposed. The single point light emitting devices 410 may correspond to spectator seats, such as one spectator seat, corresponding to one or more single point light emitting devices 410. As shown in fig. 1, each image block area 40 may be an area that includes a plurality of viewer seats. The single-point light emitting device 410 may be stationary or mobile.
In some embodiments, the single point light emitting device 410 may be a stationary light emitting device 411. The fixed light emitting devices 411 are fixedly disposed in the image block region 40, and may be arranged in an array to correspond to pixel positions in the picture data of the target region. The stationary light emitting device 411 may be provided for each auditorium, e.g. on each seat, or beside the seat. The stationary light emitting devices 411 within each image block area 40 may form a lighting map. The controller 300, according to the lighting map, may correspond to the position of each fixed lighting device 411 in the image block area 40, and obtain the pixel position corresponding to the target area.
In some embodiments, as shown in fig. 1, the single point light emitting device 410 may be a mobile light emitting device 412. The mobile light emitting device 412 may be specifically a wearable structure such as a bracelet, a handheld light bar, a head ring, and clothes, and may be held or worn by the audience, and may change positions along with the movement of the audience. The mobile light emitting device 412 and the controller 300 may be connected by using a common wireless communication method, such as WiFi, bluetooth, ZigBee, NB-IoT (Narrow Band Internet of things), Long Range Radio (Long Range Radio), 5G communication technology, laser communication, and UWB (Ultra Wide Band).
When the single-point lighting device 410 is the mobile lighting device 412, since the mobile lighting device 412 may change its position with the movement of the viewer, after the controller 300 acquires the image data corresponding to the target area, the controller 300 may further locate the mobile lighting device 412 to determine the position of the mobile lighting device 412 in the image block area 40, determine the image data of the pixel point corresponding to the mobile lighting device 412, and control the lighting state and the lighting color of the mobile lighting device 412.
To facilitate the controller 300 to position the mobile light emitting device 412, the controller 300 may be arranged inside the image block area 40, such as in a central position. The controller 300 positions the mobile light-emitting device 412 using a conventional positioning method. Taking the controller 300 and the mobile light-emitting device 412 wirelessly communicate via WiFi as an example, a triangulation method may be used to observe one of the observed quantities such as RSSI, toa (time of arrival), tdoa (time difference of arrival), aoa (angle of arrival), and the like between the mobile light-emitting device 412 and a plurality of signal nodes ap (access points), and position the mobile light-emitting device 412 by using a triangulation algorithm. In some embodiments, a signal node AP may be provided on each controller 300, and the location of the controller 300 may be predetermined. Triangulation is achieved using the controller 300 in the adjacent image block area 40. In some embodiments, 2 or more signal nodes AP may be provided within each image block area 40, and the inside of each image block area 40 may be triangulated.
It is understood that other positioning methods, such as centroid positioning, polytropic positioning, fingerprint positioning, etc., may be used to position the mobile light-emitting device 412.
Since the position of the mobile lighting device 412 is changed, the position in the image block area 40 may not correspond to the pixel point corresponding to the target area, and at this time, the controller 300 may calculate the picture data of the corresponding position of the mobile lighting device 412 in the target area according to the picture data of the pixel points around the corresponding position of the mobile lighting device 412 in the target area. For example, the picture data of the corresponding position of the mobile light emitting device 412 in the target area may be obtained by interpolation according to the picture data of the surrounding pixel points. In some embodiments, the interpolation may also take into account the distance between the corresponding location of the mobile light-emitting device 412 in the target area and the corresponding location of the surrounding pixel points in the target area. In some embodiments, the image data of the corresponding position of the mobile light-emitting device 412 in the target area may also be directly the image data of the closest pixel point, so as to reduce the data processing amount and increase the processing speed.
In some cases, the mobile lighting apparatus 412 may be in a mobile state when displaying a target jumbo image, and at this time, if the mobile lighting apparatus 412 still performs lighting operation according to the picture data of the previous position, it may cause the wrong picture data to be displayed at the new position. To avoid such a problem that the mobile lighting device 412 is continuously moved to cause a display error, during the process of displaying a huge target image, the controller 300 may periodically acquire the position of the mobile lighting device 412 according to a certain positioning frequency, and then determine the current screen data of the mobile lighting device 412 according to the current position of the mobile lighting device 412 to control the mobile lighting device 412 to perform a corresponding lighting operation. The positioning frequency can be determined according to the moving speed of the viewer and the distance from the pixel point to the image block area 40; it can also be set directly to a fixed value, such as 24Hz, 60Hz, etc., as long as it can be ensured that the mobile light-emitting device 412 can be prevented from moving from one pixel point position to another between two positioning.
In some embodiments, the single point light emitting device 410 is a mobile light emitting device 412, wherein a portion of the mobile light emitting device 412 is configured as a boundary point light emitting device for determining the boundary of the image block area 40. For example, 4 mobile lighting devices 412 can be set as boundary point lighting devices, the positions of the boundary point lighting devices are four vertices of the image block area 40, and the four vertices are connected to obtain the image block area 40. Since the border point lighting is a mobile lighting 412, the position can be moved and thus the image block area 40 can also be moved and not fixed at a specific location in the venue.
It is understood that the number of the boundary point light-emitting devices may be 1, 2, 3 or more, as long as one image block area 40 can be formed by the boundary point light-emitting devices. The shape of the image block area 40 is not limited to a square, and may be a polygon or a circle. For example, when 1 boundary point light emitting device is adopted, the position of the boundary point light emitting device may be used as the center of the image block area 40, and a circular image block area 40 may be obtained according to a preset radius; alternatively, a square image block area 40 may be obtained by extending a predetermined length in two predetermined directions perpendicular to each other. For example, when 2 boundary point light emitting devices are adopted, a connecting line of the positions of the 2 boundary point light emitting devices may be used as a diameter to obtain a circular image block area 40; a square image block area 40 may be obtained as a diagonal line of the square.
Then, by locating the positional relationship between the mobile light-emitting device 412 and the boundary point light-emitting device, its corresponding pixel point position in the target area is determined. The controller 300 controls the mobile lighting device 412 in the image block area 40 to perform lighting operation, thereby displaying a huge image.
Therefore, a dynamic image block area 40 can be formed by utilizing the mobile light-emitting device, the image block area 40 is not fixed any more but can be moved, a mobile huge image can be conveniently formed on the spot of a venue, and the display effect and the on-spot atmosphere are effectively improved.
In some embodiments, within one image block area 40, both the stationary light emitting device 411 and the mobile light emitting device 412 may be disposed.
The light emitting areas of the fixed light emitting device 411 and the movable light emitting device 412 may be the same or different. In order to ensure the picture effect, when the light-emitting areas of the single-point light-emitting devices 410 are different, the light-emitting brightness can be adjusted correspondingly. For example, a single-point light emitting device 410 with a large light emitting area may have a lower light emitting brightness; and a single-point light emitting device 410 with a small light emitting area may have a relatively high light emitting brightness.
The target jumbo image is displayed mainly for viewing by the audience in the field and other areas. To further ensure that the displayed target jumbo image can be viewed in multiple directions, the single-point light emitting device 410 may be configured to emit light in multiple directions. For example, the single-point light emitting device 410 may include three sub-light emitting units, namely a red LED, a green LED, and a blue LED, and each sub-light emitting unit is provided with LED beads emitting light in multiple directions, for example, the light emitting directions may include a front direction, a left direction, and a right direction, and may further include a direction inclined to the ground. It will be appreciated that more or different light emitting directions may be provided according to actual needs, for example, a direction toward a camera for shooting on the scene, and so on.
The image processing apparatus 100 may directly transmit the picture data of the complete target jumbo image to each controller 300, or may respectively transmit the picture data of the corresponding target area according to the image block area 40 corresponding to each controller 300. The image processing apparatus 100 is communicatively connected to the controller 300, such as a wired communication connection or a wireless communication connection. Generally, the area of the stadium is large, and a plurality of image block regions 40 may be divided, and accordingly, the number of the controllers 300 is very large. If the image processing apparatus 100 transmits the complete picture data of the target jumbo image to each controller 300 without dividing the target jumbo image, it may impose a relatively high requirement on the communication bandwidth, and the controller 300 needs to intercept the picture data of the corresponding target area from the target jumbo image, which results in a large data processing amount and a slow processing speed, and seriously affects the display speed. However, if the image processing apparatus 100 divides the target jumbo image into the frame data corresponding to the respective controllers 300, the image processing apparatus 100 may consume a lot of time for the division process because of the large number of controllers 300, which may affect the display speed.
In order to balance the communication bandwidth and the display speed, as shown in fig. 2 and fig. 3, the jumbo image display system may further include a plurality of card receiving units 200, wherein a plurality of controllers 300 are grouped into one group, and each group of controllers 300 is communicatively connected to one card receiving unit 200; the image processing apparatus 100 transmitting the picture data of the target jumbo image to the receiving card unit 200; the receiving card unit 200, which divides the received image data of the target jumbo image according to the image block area 40 corresponding to the connected controller 300, and transmits the intercepted image data of the target area to the corresponding controller 300; the controller 300 receives the picture data of the target area, acquires the position of the single-point light emitting device 410 in the image block area 40, and controls the light emitting state and the light emitting color of the single-point light emitting device at the corresponding position.
The image processing apparatus 100 may transmit the picture data of the complete target jumbo image to each of the receiving card units 200. In some embodiments, the image processing apparatus 100 may also divide the target jumbo image, and send only the picture data of the control area corresponding to the receiving card unit 200 to the corresponding receiving card unit 200.
The receiving card unit 200 may perform the aforementioned point-to-point communication with each group of controllers 300, and the receiving card unit 200 divides the picture data of the target jumbo image and transmits only the picture data corresponding to the respective target areas to the corresponding controllers 300. Communication between the receiving card unit 200 and each group controller 300 may also be in the form of broadcasting. At this time, the receiving card unit 200 does not divide the received screen data of the target jumbo image, but the controller 300 itself performs the division processing. In some embodiments, each group of controllers 300 is connected in series, and the first controller 300 receives the picture data of the target jumbo image from the receiving card unit 200, intercepts the picture data corresponding to its target area therefrom, and then forwards the remaining picture data to the subsequent controller 300, and the subsequent controller 300 intercepts the picture data therefrom and forwards it backward in turn.
In order to improve the display effect of the target huge image, the huge image display system can also comprise an ambient brightness sensor for acquiring ambient brightness; an image processing apparatus 100 that can set the display luminance of the target jumbo image according to the ambient luminance; the controller 300 controls the luminance of the single-point light emitting device according to the display luminance of the target jumbo image.
Since the image block area 40 in the jumbo image display system may include a large area, and different areas may have different brightness, i.e. different light emitting brightness is required, in some embodiments, a plurality of ambient brightness sensors may be provided, each ambient brightness sensor may correspond to an area of one set of the controller 300, and the receiving card unit 200 may set the display brightness of the target jumbo image according to the ambient brightness.
In some embodiments, an ambient brightness sensor may be disposed corresponding to each image block area 40, and the controller 300 may set the display brightness of the target jumbo image according to the ambient brightness, and control the light emitting brightness of the single-point light emitting device.
Compared with the existing scheme of forming a huge image by the resultant force of audiences, the huge image display system fused in the venue provided by the embodiment of the application can realize the automatic display of the huge image in the audience area in the venue without the cooperation of the audiences; moreover, the content of the huge image can be randomly changed, the display effect is better, the watching experience of audiences can be effectively improved, and the field atmosphere is improved.
As shown in fig. 4, an embodiment of the present application discloses a method for controlling display of a jumbo image fused in a venue, including:
s100, the image processing equipment acquires a target jumbo image and distributes the picture data of the target jumbo image to a receiving card unit;
the image processing equipment can send the picture data of the complete target jumbo image to each receiving card unit; the target jumbo image may be divided, and only the picture data of the area corresponding to the card receiving unit may be sent to the corresponding card receiving unit.
S200, the receiving card unit receives and divides the picture data of the target jumbo image to obtain the picture data of the target area corresponding to each controller, and sends the picture data of the target area to the corresponding controller;
the receiving card unit corresponds to a set of controllers. And the receiving card unit is used for intercepting the image data of the target area corresponding to the controller from the received image data of the target jumbo image according to the position of the image block area corresponding to the controller and sending the intercepted image data of the target area to the corresponding controller.
S300, the controller receives the picture data of the target area, obtains the position of the single-point light-emitting device in the image block area corresponding to the controller, determines the picture data of the position corresponding to the single-point light-emitting device, and controls the single-point light-emitting device to emit light.
The single-point light emitting device may be a fixed light emitting device, is fixedly disposed in the image block region, and may be arranged in an array to correspond to the pixel positions in the image data. Therefore, the controller can store a lighting map of the single-point light-emitting devices in the image block area, and according to the lighting map, the position of each fixed light-emitting device in the image block area can be correspondingly determined. The image data of the target area corresponds to the image block area, that is, the image data corresponding to the specific position in the image block area can be determined, and the controller controls the single-point light-emitting device at the specific position to perform the corresponding light-emitting state and light-emitting color according to the image data at the specific position.
In some embodiments, a single point lighting device, which may also be a mobile lighting device, is held or worn by a viewer and may change position as the viewer moves. And the mobile light-emitting equipment is in wireless communication connection with the controller. And the controller needs to position the single-point light-emitting device to acquire the position of the single-point light-emitting device in the image block area corresponding to the controller. The mode of the controller for positioning the single-point light emitting device can be common positioning methods such as a triangulation positioning method, a centroid positioning method, a changeable positioning method, a fingerprint positioning method and the like. For example, the controller and the mobile lighting device may communicate using WiFi. The controller obtains one of observed quantities such as signal strength RSSI, propagation time TOA (time of arrival), propagation time difference TDOA (time difference of arrival), and incidence angle AOA (angle of arrival) between the mobile light-emitting device and a plurality of signal nodes AP (access point), and uses a triangulation algorithm to position the mobile light-emitting device. The signal node AP may be provided in the controller, or may be provided separately.
The position of the mobile light-emitting device in the image block region may not correspond to the pixel point corresponding to the target region, and at this time, the controller may calculate the picture data of the corresponding position of the mobile light-emitting device in the target region according to the picture data of the pixel points around the corresponding position of the mobile light-emitting device in the target region, for example, the picture data of the pixel point closest to the corresponding position of the mobile light-emitting device may be calculated by using an interpolation method, or may directly adopt the picture data of the pixel point closest to the corresponding position of the mobile.
In order to avoid the problem of picture display errors caused by continuous movement of the mobile light-emitting device, in the process of displaying a target huge image, the controller can periodically acquire the position of the mobile light-emitting device according to a certain positioning frequency, then determine the current picture data of the mobile light-emitting device according to the current position of the mobile light-emitting device, and control the mobile light-emitting device to perform corresponding light-emitting work. The positioning frequency can be determined according to the moving speed of the audience and the distance of the pixel points corresponding to the image block area; it can also be set directly to fixed values such as 24Hz, 60Hz, etc.
It is understood that the single-point lighting device may include both a stationary lighting device and a mobile lighting device.
