Abstract

The invention discloses an ultrasonic positioning device for a four-rotor unmanned aerial vehicle. The device comprises the four-rotor unmanned aerial vehicle, an ultrasonic emission control module, an ultrasonic emission module, an ultrasonic receiving control module and a plurality of ultrasonic receiving modules. The ultrasonic receiving control module is connected with the ultrasonic receiving modules and fixed to the ground, one end the ultrasonic emission control module is connected to the output end of a flight control plate of the ultrasonic emission control module, and the other end of the ultrasonic emission control module is connected with the ultrasonic emission module. According to an ultrasonic positioning method for the four-rotor unmanned aerial vehicle, the ultrasonic receiving modules are adopted, every three ultrasonic receiving modules form one set for spatial positioning, the positioning result and positioning results of other sets are corrected mutually, positioning precision is improved, and errors are reduced. The ultrasonic positioning method for the four-rotor unmanned aerial vehicle has the advantages of being easy to operate, simple and accurate in calculation, low in computing resource requirement for a factual system and relatively low in cost, and can achieve the positioning precision of the four-rotor unmanned aerial vehicle more easily.

Description

technical field

[0001] The invention relates to the field of UAV positioning, in particular to an ultrasonic positioning device and method for a quadrotor UAV. Background technique

[0002] In recent years, the role of unmanned aerial vehicles (UAVs) in ground reconnaissance and surveillance, intelligence acquisition, inspection of high-voltage lines and road sections after earthquakes, aerial photography and imaging has become more and more obvious. The six-degree-of-freedom front-drive system has a more compact structure and a simpler mechanical structure, and the four rotors of the quadrotor UAV can cancel each other's counter-torque, and the attitude and trajectory can be controlled by controlling the speed of the motor. control. However, the research on target positioning in the use of quadrotor UAVs is a little lagging behind, especially the precise positioning of targets is more difficult, which is not conducive to the realization of quadrotor UAVs for reconnaissance...
