Embodiment 2

[0047] An automatic barrier method for unmanned aerial vehicles based on two-dimensional laser radar, comprising the following steps:

[0048] S1. The data acquisition module collects the real-time data of the UAV in real time;

[0049] S2. The information processing unit of the data acquisition module packages and transmits the information collected by the data acquisition module to the data fusion processing module in real time;

[0050] S3. The data fusion processing module constructs a real-time virtual three-dimensional scene according to the real-time information obtained by the data acquisition module, performs data analysis according to the constructed real-time virtual three-dimensional scene, and generates an obstacle avoidance command according to the analysis result;

[0051] S4. The information processing unit of the data fusion processing module sends the obstacle avoidance command to the information processing unit of the obstacle avoidance control module, repla...

Abstract

The invention discloses an unmanned aerial vehicle automatic barrier avoidance system based on a two-dimension laser radar. The system comprises a data acquisition module, a data fusion processing module and a barrier avoidance control module. The data acquisition module comprises a laser radar unit, a camera unit, a positioning unit and a flight condition monitoring unit. The data fusion processing module comprises a data fusion processing unit, an SLAM operation unit, a data analysis unit and a barrier avoidance command generating unit. The barrier avoidance control module comprises a route planning unit and a barrier avoidance command execution unit. The automatic barrier avoidance method comprises the steps that the data acquisition module acquires unmanned aerial vehicle real-time data in real time and transmits the data to the data fusion processing module; the data fusion processing module constructs a real-time virtual three-dimensional scene according to the real-time data; data analysis is carried out according to the constructed real-time virtual three-dimensional scene; a barrier avoidance command is generated and sent to the barrier avoidance control module; and route re-planning and barrier avoidance control are carried out according to the received barrier avoidance command to realize automatic barrier avoidance of an unmanned aerial vehicle.

Description

technical field [0001] The present invention relates to an unmanned aerial vehicle control system, in particular to an automatic obstacle avoidance system and method for an unmanned aerial vehicle based on a two-dimensional laser radar. Background technique [0002] UAV is a kind of unmanned aircraft operated by radio remote control equipment and self-contained program control device. UAVs are widely used in industries such as electric power, meteorology, agriculture, video photography, emergency rescue and disaster relief. However, as the application of UAVs becomes more and more extensive, and the operating environment becomes more and more complex and changeable, UAVs are required to be more intelligent and convenient. At present, drones are divided into three types of flight modes: manual flight, semi-automatic flight and automatic pilot flight. The first two require flight control technicians to operate the drone in real time to control the flight route. Autopilot fli...
