Large-scale cooperative monitoring method and device for UAV group

Abstract

The invention discloses a large-scale cooperative monitoring method and device for a UAV group, and belongs to the technical field of UAVs. The device includes a number of UAVs, and each UAV is provided with a flight control device, a 360-degree laser scanning ranging radar, a development board, a high-definition camera, a three-axis pan / tilt, an optical flow sensor, a high-brightness fill-in light source, and a wind speed measurement instrument. The flight control device controls the UAV to fly autonomously according to the formation. Each UAV detects the surrounding environment through the 360-degree laser scanning ranging radar. If the environment is very dark, the high-brightness fill-in light source is automatically turned on. During the flight, the high-definition camera shoots and monitors the lower environment, and the optical flow sensor and the three-axis pan / tilt maintain the stability of the body and the high-definition camera. When in the conflict state, the flight controldevice changes the flight direction of the UAV and resolves the conflict. The final captured image is sent to the development board to detect the presence of an abnormal area. The invention can realize large-scale monitoring, has high efficiency, and reduces labor cost.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, in particular to a large-scale cooperative monitoring method and device for an unmanned aerial vehicle group. Background technique [0002] With the continuous development of UAV technology, the application fields are also expanding: including crop monitoring, film and television shooting and post-disaster rescue, etc. At the same time, UAV swarm cooperation has also become an important development trend. UAV swarms can control a larger range, realize functional complementarity and task sharing, etc. Therefore, the UAV swarm system can perform complex tasks, shorten the time for performing tasks, and improve attendance efficiency.

[0003] Environmental monitoring under uncertain conditions is a very important task. The traditional method is to monitor by manpower. This monitoring method consumes a lot of labor costs, and some dangerous environments may threaten the lives of inspectors.

At the same time, due to the different working ability of each person, there may be negligence in human monitoring

And areas such as mountains, lakes, and forests cannot be monitored by installing fixed cameras due to their huge size.
