[0034] see figure 2 , showing the application provided by the first embodiment of the present invention figure 1 The flow chart of the return-finding method of the aircraft 100 is shown. The method steps defined by the flow process related to the method can be implemented by the processor 106 . The following will be figure 2 The specific process shown will be described in detail. Such as figure 2 As shown, the return-to-home finding method provided in the first embodiment of the present invention may include the following steps.

[0035] The flight test step S11 is to control the aircraft 100 to test the first preset distance along multiple flight test directions, and obtain the distance between the flight test end point and the remote controller in each flight test direction.

[0036] The first execution of the flight test step S11 is triggered when the communication unit 110 receives a return instruction sent by the user through the remote control. Once the return ins...

[0056] see Figure 11 , the return-to-home tracking device 200 provided in the second embodiment of the present invention includes a flight-test control module 210 and a return-to-home control module 220 .

[0057] The flight test control module 210 is used to control the aircraft 100 to test the first preset distance along multiple flight test directions, and obtain the distance between the flight test end point and the remote controller in each flight test direction.

[0058] The flight test control module 210 is initially triggered when the communication unit 110 receives a return instruction sent by the user through the remote controller. Once the return instruction is received, the flight control unit 108 of the aircraft 100 controls the aircraft 100 to hover. Then, the return flight control module 220 controls the aircraft 100 to take the current hovering position as the starting position of the flight test and fly the first preset distance along multiple test flight di...

Abstract

The embodiment of the invention proposes a return hunting method and device and an aircraft. The method comprises a test flight step: controlling the aircraft to flight a preset distance in a plurality of test flight directions, and obtaining the distance between a test flight end point and a remote controller in each test flight direction; a returning step: determining the returning direction of the aircraft according to the distance between the test flight end point and the remote controller in each test flight direction, and controlling the aircraft to flight a second preset distance in the returning direction; a step of repeatedly carrying out the test flight step and the returning step till the distance between the test flight end point and the remote controller is less than or equal to a preset threshold value. According to the embodiment of the invention, after a returning instruction is received, the aircraft can return to the position of the remote controller nearly along a straight line in a mode of carrying out locating through a non-absolute position, and can improve the returning efficiency.

Description

technical field [0001] The present invention relates to the technical field of aircraft control, and in particular, relates to a method and device for returning a route and finding a route, and an aircraft. Background technique [0002] In the field of unmanned aerial vehicles, there are many return modes of the aircraft. The common way is to use GPS (Global Position System, Global Positioning System) or other methods to perform absolute position positioning and then return to the previously set position. Such a method is usually implemented in the following manner: the aircraft performs absolute position positioning according to an absolute position positioning module (such as GPS) when returning home, so as to return to the starting position when the aircraft takes off along a straight line from the current end position. However, the absolute position positioning that utilizes an absolute position positioning module (such as a GPS module) may produce errors in some cases, ...
