Problems solved by technology

[0004] However, in the face of complex environments affected by multiple factors in reality, this control mode is no longer sufficient to effectively avoid unforeseen threats
At the same time, in some small-scale complex terrain environments, the success rate of drones avoiding obstacles has dropped significantly.

Abstract

The invention discloses an unmanned aerial vehicle autonomous flight system based on image recognition. The unmanned aerial vehicle autonomous flight system is applied to an autonomous flight task composed of n unmanned aerial vehicles and a ground command center. The unmanned aerial vehicle autonomous flight system is characterized by comprising a flight communication module, a ground communication module, an input module, an FFMPEG module, a video display module, an image recognition module, an instruction generation module and an output module. The flight communication module and the ground communication module each comprise a UDP5556 port and a TCP5555 port. When the unmanned aerial vehicles fly autonomously, the unmanned aerial vehicle autonomous flight system can make more timely response and adjustment according to the random environmental change to ensure stability and flexibility of autonomous flight of the unmanned aerial vehicles.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle control and decision-making. Specifically, it is a UAV autonomous flight system based on image recognition. Background technique [0002] In recent years, UAVs have been widely used in communication, meteorology, military and other fields because of their excellent performance of high-risk tasks in boring and harsh environments. UAV technology has developed rapidly in the direction of miniaturization, invisibility and intelligence. [0003] However, in the current mainstream design of UAV autonomous flight system, the ground control base station program involved—whether it is simply with the help of a program or a hierarchical structure control system based on an intelligent agent—the underlying navigation control is based on The real-time position of the UAV is determined by the direction positioning system (mainly including the three parts of GPS positioning system, compass system and he...
