Example

[0029] First embodiment

[0030] Please refer to figure 2 , figure 2 It shows a flowchart of a method for setting a flight route provided by a preferred embodiment of the present invention. The flight route setting method is applied to drone aerial photography, which includes the following steps:

[0031] Step S101: Obtain the flight altitude of the drone, and set the flight altitude as the altitude of the first flight path.

[0032] In the embodiment of the present invention, the flying altitude of the drone may be the height of the drone from the ground, which can be calculated by the following calculation formula:

[0033] Among them, H is the flight altitude, GSD is the ground resolution, f is the focal length of the camera, and a is the pixel size of the camera CCD (Charge-coupled Device). The unit of flight altitude is meters, and in actual use, use 2 decimal places, which is accurate to millimeters. It should be noted that the ground height needs to be collected during the...

Example Embodiment

[0051] Please refer to Figure 4 , Figure 4 This is the laying diagram of the inter-cultivation route provided by the first embodiment of the present invention. As an implementation manner, the survey area is divided into a first survey area and a second survey area, in the first survey area and the second survey area respectively Set the same number (for example, 4) inter-cultivation routes, and the distance between any two adjacent inter-cultivation routes is the distance between the UAV's air belt. It is possible to set multiple inter-farming routes in the first measurement area to be in the first direction, and multiple inter-farming routes in the second measurement area to be in the second direction. The first direction is opposite to the second direction. For example, the first direction is To the right, the second direction is to the left. in Figure 4 In the laying diagram of the inter-farming route, the flying direction of the drone is to fly along the inter-farming r...

[0081] Second embodiment

[0082] Please refer to Picture 8 , Picture 8 It shows a schematic block diagram of a flight route setting device 200 provided by a preferred embodiment of the present invention. The flight path setting device 200 includes a flight altitude acquisition module 201, a first flight path setting module 202, a second flight path setting module 203, a flight path determination module 204, and an exposure point setting module 205.

[0083] The flight altitude obtaining module 201 is used to obtain the flight altitude of the drone, and set the flight altitude as the altitude of the first flight path.

[0084] In the embodiment of the present invention, the flight altitude acquisition module 201 may be used to execute step S101.

[0085] The first flight path setting module 202 is configured to set a first flight path according to the obtained flight parameters of the drone, where the first flight path includes multiple cropping routes.

[0086] In the embodiment of ...

Abstract

The invention relates to the technical field of unmanned aerial vehicles, provides a flight route setting method and device, and is applied to aerial photography of the unmanned aerial vehicle. The method comprises the steps that a first flight path is set according to the acquired flight parameters of the unmanned aerial vehicle, wherein the first flight path includes multiple double plough routes; a second flight path is set according to the first flight path, wherein the second flight path includes multiple skeleton routes, and the skeleton routes and the double plough routes are distributed in an interwoven way; and the first flight path and the second flight path are combined so as to determine the flight route of the unmanned aerial vehicle. The first flight path and the second flight path are combined to set the flight route of which the skeleton routes and the double plough routes are distributed in an interwoven way so that the number of field operation control points can be effectively reduced and the field operation difficulty of the aerial photography of the unmanned aerial vehicle can be reduced.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular, to a method and device for setting flight routes. Background technique [0002] In recent years, UAV aerial photogrammetry has developed rapidly. Compared with traditional photogrammetry technology, UAV has the advantages of high mobility, high resolution, low cost, and flexible operation. It has been widely used in small and medium-sized area measurements. application. UAV aerial photography not only requires high-level flight technology, but also includes efficient route design. The accuracy and automation level of the plan directly affect the quality and efficiency of aerial photography. [0003] At this stage, UAV aerial photogrammetry mainly adopts the common serpentine route flight mode for flight. After the flight operation, it mainly relies on the field measurement image control point and manual pricking method for processing in the office, which c...
