Embodiment 1

[0106] A piece of geomorphic data with an orthographic area of ​​about 9 mu was collected in a mountainous area. In remote mountainous areas, AutoNavi, Baidu, Tencent, Tiantu, etc. do not have high-resolution satellite remote sensing images and vector map data in the area. Collect data according to the following procedure.

[0107] 1. Turn on the drone and the remote controller of the drone.

[0108] 2. Fly the UAV at a certain height, so that the pre-acquisition area is in the interface of the UAV's gimbal camera, which is assumed to be 50m here.

[0109] 3. Click Generate Route, the software will automatically generate the route, the specific calculation is as follows:

[0110] (1) First calculate the size of the actual area imaged by the UAV at a height of 50m,

[0111] Width W = 2*tan(84 / 2)*50 ≈90.04,

[0112] Image height H = 3*W / 4=67.53,

[0113] Distance from four anchor points ≈112.55,

[0114] phase angle =23.57°;

[0115] (2) Then calculate the latitude a...

Embodiment 2

[0135] Collect data of an agricultural water conservancy project with an orthographic area of ​​about 36 mu in a mountainous area. In remote mountainous areas, AutoNavi, Baidu, Tencent, Tiantu, etc. do not have high-resolution satellite remote sensing images and vector map data in the area. Collect data according to the following procedure.

[0136] 1. Turn on the drone and the remote controller of the drone.

[0137] 2. Fly the UAV at a certain height, so that the pre-acquisition area is in the interface of the UAV's gimbal camera, which is assumed to be 100m here.

[0138] 3. Click Generate Route, the software will automatically generate the route, the specific calculation is as follows:

[0139] (1) First calculate the size of the actual area imaged by the UAV at a height of 100m,

[0140] Width W = 2*tan(84 / 2)*100 ≈180.08,

[0141] Image height H = 3*W / 4=135.06,

[0142] Distance from four anchor points ≈225.1,

[0143] phase angle =23.57°,

Abstract

The invention belongs to the technical field of unmanned aerial vehicle aerial photography collection, and particularly relates to a method for rapidly and accurately collecting low-altitude remote sensing images based on an unmanned aerial vehicle technology, the unmanned aerial vehicle flies to a certain height, a camera vertically faces the ground, and the imaging range of the camera completely covers a target area, namely a collection area range; the width of the imaging range is calculated through the flight height of the unmanned aerial vehicle and the wide angle of the camera, and the length of the imaging range is calculated through the width-to-length ratio of the camera; longitudes and latitudes of four vertexes of an imaging range are calculated according to the longitudes and latitudes of a current GPS positioning point of the unmanned aerial vehicle, and a target area is determined; and a task route of the unmanned aerial vehicle is planned according to the target area, wherein the unmanned aerial vehicle flies according to the task route to complete the aerial photography task. The method is mainly used for solving the problems of how to quickly, accurately and automatically complete route planning of a target area and how to integrally and automatically collect orthoimages under the condition that no available satellite remote sensing image data exists or the satellite remote sensing image data is invalid in the aerial photography activity of the unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle aerial photography acquisition technology, and specifically designs a method for quickly and accurately collecting low-altitude remote sensing images based on unmanned aerial vehicle technology.
