Description

technical field [0001] The invention relates to an unmanned aerial vehicle-based multi-angle remote sensing automatic observation system. Background technique [0002] In recent years, with the rapid development of quantitative remote sensing, multi-angle remote sensing has become one of the hot research fields, but the acquisition of multi-angle data is a difficult problem, so the development of various multi-angle observation systems is the basic work of multi-angle remote sensing . From the perspective of multi-angle remote sensing data acquisition methods, there are currently three main methods: based on satellite platforms, based on aerial platforms, and based on ground observations. The satellite platform can provide a large amount of multi-angle observation data on the ground through the superposition of the sensor field of view, and the data is stable and reliable. Not applicable in remote sensing. Therefore, various scientific research units have invented a serie...

Problems solved by technology

From the point of view of the existing aviation multi-angle observation data acquisition methods, the observation is mainly carried out by fixed-wing aircraft equipped with sensors. The problems faced by this observation method are huge cost, inflexible flight routes, long flight time, and cumbersome procedures. All the data obtained in this way is relatively small

[0003] At present, the development of the aviation multi-angle automatic observation system needs to solve the following problems: first, the problem of fast data acquisition, the previous aerial telemetry platform is not flexible in flight, and the flight time is long, during which the sun's altitude angle will change significantly , resulting in inaccurate observation data, especially for thermal infrared observations

The second is the issue of flexibility, including both time and space. Traditional aerial observations use large fixed-wing aircraft, which require special airstrips, which is very inconvenient for observations in remote areas. small remote mountains
