Embodiment Construction

[0031] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. 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.

[0032] refer to figure 1 and image 3 It can be seen that the communication steps are:

[0033] Step 1: The first step is based on other technologies, the transmitting UAV sends positioning light to the receiving UAV;

[0034] Step 2: The receiving drone obtains the approximate position of the transmitting drone through the calculation of the acceptance angle;

[0035] Step 3: The receiving UAV feeds back the light angle, intensity, rec...

Abstract

The invention discloses an unmanned aerial vehicle closed-loop positioning device and method based on optical communication, and the device and method are used for receiving an optical signal which can be received by an unmanned aerial vehicle at the most appropriate position through positioning during the optical communication of the unmanned aerial vehicle. In the method, a transmitting unmanned aerial vehicle transmits a time-varying LED matrix to a receiving unmanned aerial vehicle after performing coarse positioning on the receiving unmanned aerial vehicle by using a camera; the receiving unmanned aerial vehicle judges the relative position, the receiving light angle and the like of the receiving unmanned aerial vehicle according to the received data and feeds back to the transmitting unmanned aerial vehicle, and the two are continuously adjusted to achieve optimal information transmission.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicle technology and optical communication technology, specifically a closed-loop positioning device and method for unmanned aerial vehicle based on optical communication. Background technique [0002] Under modern combat conditions, drones have become the main military equipment used in local wars. At present, UAVs use radio frequency communication as traditional battlefield communication, so the UAV system needs to continuously improve its anti-electromagnetic interference capability to adapt to the complex electromagnetic environment requirements of the battlefield. Regardless of the influence of natural magnetic field interference such as lightning and electronic noise interference, on the battlefield, the interference technology for radio frequency communication is also developing continuously. The emerging radiation interference and conduction interference technology can cause errors...
