Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. The specific technical scheme is as follows:

[0037] The invention discloses an unmanned aerial vehicle group positioning system and a positioning method, which can perform positioning and navigation in places such as tunnels or caves where satellite signals are poor. In places with poor satellite signals such as tunnels or caves, there are multiple drones flying inside to form a drone group, in which each drone carries a tag with or without information. Put a label on the corresponding position, and at the same time give the label location information and return the lo...

Abstract

The invention discloses an unmanned aerial vehicle group positioning system and method. The unmanned aerial vehicle group positioning system can perform positioning navigation in places with poor satellite signals such as tunnels or caves. In places with poor satellite signals such as tunnels or caves, a plurality of unmanned aerial vehicles fly in the places to form an unmanned aerial vehicle group. One unmanned aerial vehicle in the unmanned aerial vehicle group serves as a leader in positioning and navigation and can transmit signals to other unmanned aerial vehicles to inform the other unmanned aerial vehicles of the walking direction so as to control the formation, specify the positioning unmanned aerial vehicle and assist the positioning unmanned aerial vehicle. Each unmanned aerialvehicle carries an information-free label, the unmanned aerial vehicle attaches a label to the corresponding position in the flight process, and label position information is given while labeling is conducted, and the position information of the label at the position is returned to the system, so that subsequent positioning and navigation can be facilitated. The system and the method have the advantages that automatic positioning and navigation can be realized in places with poor satellite signals, such as tunnels or caves, personal safety is guaranteed, and accurate navigation is realized.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle group positioning system and a positioning method, and belongs to the technical field of unmanned aerial vehicles. Background technique [0002] At present, most of the positioning systems at home and abroad are based on satellite navigation systems, such as the commonly used GPS system. The positioning technology used is usually time difference of arrival (TDOA) positioning technology, which can effectively reduce the impact of obstacles on positioning accuracy. However, in places with poor satellite signals such as tunnels or caves, the positioning of the navigation system is not accurate. Therefore, in these special environments, several technologies such as manual detection and positioning and semi-automatic instrument detection and positioning are often used. There is only two or three hours of detection time, which leads to a very short manual detection line; semi-automatic instrument detection ...
