Embodiment Construction

[0025] Hereinafter, preferred examples of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the protection scope of the present invention.

[0026] Such as figure 1 As shown, the present invention includes the following steps:

[0027] 1) The detection device is mainly composed of a small drone and its supporting remote control and a host computer. The host computer and the small drone are connected by a wireless transmission module. The small drone is equipped with a GPS positioning module and a barometer. , Gyroscope and PTZ mechanism with camera;

[0028] 2) Divide the area to be detected into sub-regions, and set the image collection point of each sub-region and the coordinate position, height and aerial angle of the image collection point;

[0029] 3) The coordinate position, height, and aerial angle information of ...

Abstract

The invention discloses a real-time detection method for drought status in a detected area based on a miniature unmanned plane. By employing the miniature unmanned plane and a matched remote controller and a host computer, the host computer and the miniature unmanned plane are connected through a wireless transmission module, a cloud deck mechanism with a camera is loaded on the miniature unmanned plane; sub areas are divided, image acquisition points, coordinate position, height and aerial photography angles can be set, and are sent to the miniature unmanned plan according to a sampling sequence, the coordinate position information received by the miniature unmanned plane is used, automatic cruise acquisition detection is carried out, the plane images in the detected area can be obtained by splicing images, and the drought status can be determined through a meteorology drought grade standard. The drought status detection is carried out by employing the camera of the unmanned plane, the camera can substitute a satellite for real-time monitoring, acquisition of high-resolution image is realized, disadvantage that image can not be obtained due to shielding of a cloud layer by satellite remote sensing can be made up, and problems of long revisiting period and untimely emergency of traditional satellite remote sensing can be solved.

Description

Technical field [0001] The invention relates to a drought monitoring method, in particular to a drought monitoring method in a detected area based on a small drone. Background technique [0002] Drought usually refers to a climatic phenomenon in which the total amount of fresh water is insufficient for human survival and economic development. It is generally a long-term phenomenon. Drought has been a major natural disaster faced by humans since ancient times. Even today when science and technology are so advanced, the catastrophic consequences it causes are still everywhere. It is especially worth noting that with human economic development and population expansion, water shortages have become more and more serious. This has also directly led to the expansion of arid areas and the increase of aridification. The trend of aridification has become a global concern. [0003] The national standard of "Meteorological Drought Grades" divides drought into five grades, and assesses the imp...
