Retrieving apparatus and method for unmanned aerial vehicle

Abstract

The invention provides a retrieving apparatus and method for an unmanned aerial vehicle, belonging to the field of unmanned aerial vehicles. The retrieving method for the unmanned aerial vehicle comprises the following steps: acquiring the flight position information of the unmanned aerial vehicle via a wireless network at regular time and storing the flight position information; reading the latest stored position information of the unmanned aerial vehicle after receiving a request for retrieving the unmanned aerial vehicle; positioning the location of the unmanned aerial vehicle according to the position information; acquiring the position information of an operator and determining the location information of the unmanned aerial vehicle relative to the operator according to the position information of the operator and the position information of the unmanned aerial vehicle; and outputting the location information of the unmanned aerial vehicle relative to the operator. According to the method, the position information of the unmanned aerial vehicle in flight is recorded; on the circumstance that the unmanned aerial vehicle is lost, a location range where the unmanned aerial vehicle lands or falls can be positioned according to the latest stored position information of the unmanned aerial vehicle, and the location of the unmanned aerial vehicle relative to the operator is output; thus, a searching range can be reduced, rapid retrieving of the unmanned aerial vehicle can be realized, and economic loss can be decreased.

Description

Technical field [0001] The invention relates to an unmanned aerial vehicle, and in particular to an unmanned aerial vehicle retrieval device and method. Background technique [0002] Micro-unmanned aerial vehicles are particularly suitable for performing surveillance, reconnaissance and other tasks in near-ground environments (such as indoors, urban areas, and jungles), and have broad military and civilian prospects. However, because sometimes the UAV flies far, beyond the sight of the operator, if it is not properly controlled, the UAV may lose control and fall somewhere. If you want to retrieve the fallen one, you will need to search a large area. If the unmanned aerial vehicle falls in the bushes, it will become more difficult to find. [0003] A related search assistance method is to install an alarm on the unmanned aerial vehicle, which automatically emits a warning sound when the unmanned aerial vehicle falls. If the person looking for the unmanned aerial vehicle is not clo...

AI Technical Summary

Problems solved by technology

If the person looking for the UAV is not close enough to the UAV, it is difficult to hear the alarm sound from the siren, that is, the sound alarm has no ability to help narrow the search area

And if the UAV has a battery problem during the fall, or the battery is exhausted, it will not be able to make a sound
