Problems solved by technology

However, a common problem in these studies is that the characters or graphics to be displayed are pre-customized and designed formation scripts, and designers need to pre-calculate the positions of all UAV nodes. This system is difficult to expand and Multiplexing, while complex formation transformations cannot be realized

Embodiment Construction

[0044] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0045] In the present invention, a character display method based on multi-rotor UAV formation is provided, such as figure 1 As shown, after receiving the character display task, according to the acquired characters to be displayed, the following eight steps S1-S8 are performed, specifically including:

[0046] S1, extract character binary code;

[0047] Utilize the existing dot-matrix font to extract the multi-bit binary code corresponding to the character to be displayed. In this embodiment, the HZK16 font is used, which is a dot-matrix font that meets the GB2312 standard. Therefore, each character is represented by 32 bytes and converted i...

Abstract

The invention relates to a character display method and a character display system based on a multi-rotor unmanned aerial vehicle formation. The character display method comprises the steps of 1, acquiring a to-be-displayed character in a task, and extracting a plurality of binary system codes which correspond with the to-be-displayed character in a lattice character database; 2, arranging the plurality of binary system codes of the to-be-displayed character to a lattice, and calculating spatial geographical positions of all 1 bits in the plurality of binary system codes; 3, establishing a corresponding designation relation between all the 1 bits and the multi-rotor unmanned aerial vehicles; and 4, making the corresponding multi-rotor unmanned aerial vehicles fly to the assigned spatial geographical position according to the spatial geographical positions of each 1 bit, thereby forming the multi-rotor unmanned aerial vehicle formation display of the to-be-displayed character. The character display method and the character display system realize random formation combination and furthermore realize quick, visual and dynamic design of the formation, and basic element splitting and recombination of a complicated formation.

Description

technical field [0001] The invention relates to the application field of formation flight of multi-rotor UAVs, in particular to a character display method and system based on multi-rotor UAV formations. Background technique [0002] In the media advertising industry, effective information dissemination is crucial for businesses to build brand effects. However, in today's information surplus, traditional print media, multimedia, mobile media, etc. are difficult to quickly attract consumers' attention in terms of form. Today's era has already entered the era of two-way information interaction from the era of one-way information consumption. Industries such as media advertising face an inevitable technological revolution. On the other hand, the multi-rotor UAV technology is becoming more and more mature, and has become a hot spot for high-tech development in recent years. The use of multi-rotor UAV formations to display advertising slogans, brand images and other aerial chara...
