Description

Technical Field

[0001] The invention belongs to the technical field of water quality remote sensing monitoring, and in particular relates to a throwing target device for unmanned aerial vehicle water quality remote sensing monitoring. Background Art

[0002] Environmental monitoring refers to determining environmental quality (or pollution level) and its changing trend by measuring the representative values ​​of factors that affect environmental quality. Monitoring methods include all methods that can characterize environmental quality, such as chemistry, physics, biology, physicochemistry, biochemistry and biophysics; monitoring objects include air, water, soil, solid waste, organisms and other objects.

[0003] Accurate and comprehensive water quality monitoring is one of the important tasks of water environment protection. Remote sensing technology, especially drone remote sensing, is increasingly used in water quality monitoring due to its advantages of wide monitoring area, high data accuracy, strong mobility and low economic cost.

[0004] The main principle of remote sensing water quality monitoring is to estimate the water quality parameter content based on the ability of water to reflect sunlight, that is, reflectivity. Therefore, in the remote sensing water quality monitoring work by drone, it is necessary to place a target with a known reflectivity in the open space of the monitoring area in advance, and obtain the radiance signal of the target based on the sensor carried by the drone to estimate the downward irradiance of the sun.

[0005] However, due to the influence of factors such as cloud cover and solar altitude angle, the downward solar irradiance will change during the entire UAV flight. Therefore, it is necessary to dynamically place targets during the UAV flight to complete the calculation of the downward solar irradiance at different time periods during the UAV flight.

[0006] The existing radiation calibration boards are still made of the most primitive flexible cloth material or hard plate structure and cannot support mobile deployment. Moreover, due to the large monitoring range of drones, some areas are difficult to enter by car, making it impossible to achieve radiation calibration settings for the entire route. Remote sensing monitoring lacks radiation calibration work, resulting in the drone remote sensing water quality inversion results being seriously affected by light at different times, and the quality of remote sensing monitoring reflectivity results is seriously disturbed.

[0007] In view of this, it is very necessary to invent a throwing target device for remote sensing monitoring of water quality by unmanned aerial vehicles. Summary of the invention
