Example one
And (4) constructing a large-scale display matrix by using the unmanned aerial vehicle. At present, unmanned aerial vehicle has widely used in various occasions, and it has a great deal of advantages such as the flexible control. The control of a large number of unmanned aerial vehicles in a local area needs to plan the flight trajectories of all unmanned aerial vehicles in the area in advance, so that on one hand, collision accidents among the unmanned aerial vehicles are prevented, and on the other hand, the unmanned aerial vehicles can conveniently construct a fleet form to execute related tasks. However, for the present invention, it is possible to construct a large-scale display matrix by planning the unmanned aerial vehicles in advance into an unmanned aerial vehicle fleet, and even if the unmanned aerial vehicles are under autonomous control, they fly by themselves in a limited display area, and as long as no collision occurs between them, all the unmanned aerial vehicles in the display area can construct a large-scale display matrix. The general built-in GPS module that has of current unmanned aerial vehicle can be directly regard as display element's positioner with this GPS module, then fixes the display screen on unmanned aerial vehicle and links to each other with unmanned aerial vehicle's master control. Carry out data exchange through wireless network between unmanned aerial vehicle and the server, above-mentioned wireless network can include that WIFI, 4G, 5G, bluetooth, data broadcast etc. multiple form realize. The server marks out a display area adapted to the display content in a certain space according to the display content and the on-site display requirement. And respectively taking a certain pixel point in the display content as a reference point so as to obtain pixel coordinates of all pixel points of the display content, and also taking a coordinate corresponding to the pixel point in the display area as the reference point so as to obtain a display coordinate corresponding to each pixel coordinate in the display area.
The display content can be stored in a plurality of ways as required:
firstly, the display content is directly pre-stored in the unmanned aerial vehicle. This scheme is mainly applicable to under the relatively fixed circumstances of display content, the server is direct to send whole display content to unmanned aerial vehicle through wireless network, and when unmanned aerial vehicle entered into the display area, unmanned aerial vehicle's display control software calculates the display coordinate that unmanned aerial vehicle is located according to the physical position information that GPS orientation module obtained, then display control software calculates the corresponding display data that obtains from the display content according to the display coordinate. When the unmanned aerial vehicle receives the display synchronization signal sent by the server, the display control software controls the display screen to display according to the display data. The GPS positioning module of the unmanned aerial vehicle updates the physical position information of the unmanned aerial vehicle in real time, and meanwhile, the display control software updates the display data to display according to the physical position information in real time, so that the display content which can be displayed correctly in the display area can be ensured.
And secondly, the display content is stored in the server, and the server sends the real-time display content to the unmanned aerial vehicle. In the case where the display content is updated in real time, the display area is also required to be capable of updating the display content in real time. For this reason, when obtaining real-time display content, the server needs to send the corresponding display content to all the drones in the display area. Also, the drone may update the display content using the methods described above.
And thirdly, the display content is stored in the server, and the server sends the display data of the corresponding display pixels of the display coordinates where the unmanned aerial vehicle is located to the unmanned aerial vehicle in real time. When the display area is great or the number of unmanned aerial vehicles in the display area is great, if the access bandwidth of the server has certain limitation, the display data of all the display contents are sent to all the unmanned aerial vehicles at the same time, so that great delay is caused, and the effect of updating and displaying the display area in real time is influenced. In order to reduce the data volume during real-time transmission, the server calculates in real time to obtain the display data which needs to be displayed by each unmanned aerial vehicle in the display area, the display data are relatively small, a large number of unmanned aerial vehicles exist in the display area, and the bandwidth of the server can meet the use requirement. In addition, in order to reduce the bandwidth pressure of concurrent real-time data transmission of the server, all display contents can be sent to the display area in a broadcast mode in real time, and all unmanned aerial vehicles receive the broadcast data in a unified mode and display the data correspondingly.
Example two
The display unit that moves out of order is a flying bird. Some birds are trained to fly in groups, such as pigeons, but the flight trajectory of each bird is disordered. Generally, this embodiment can be applied to a large-scale event or an open-curtain type event of a game, etc., in which birds are flown, and a display unit is fixed to each bird. The corresponding data transmission method and the corresponding display method can refer to the implementation of one.
EXAMPLE III
The display unit moving in disorder is a stream of people or a stream of vehicles. In the open curtain type of large-scale trip activity or sports activity, have the crowd to constitute different removal square matrixes, everybody can be through handheld or the mode of fixed display element, can be with the region that the square matrix that removes turns into a demonstration. Also in the flow of motorways or in the flow of bike racing, the fixing of the display unit on each vehicle makes it possible to form a moving display matrix in a certain area. The corresponding data transmission method and the corresponding display method can refer to the implementation of one.
Example four
The display unit that moves out of order is a float that floats on the water surface. On the lake surface of the park, the floating objects can be randomly placed, then the display unit is fixed on the floating objects, the floating objects move disorderly along with the blowing of water flow or lake surface wind, and the whole lake surface can form a large-scale display matrix through the technical scheme of the invention. The corresponding data transmission method and the corresponding display method can refer to the implementation of one.
