Unmanned plane automatic landing system

Abstract

The invention relates to an unmanned plane automatic landing system. The system comprises an aerial photography camera, a landmark positioner, unmanned plane driving equipment and a main controller, wherein the aerial photography camera shoots suspected landmark region under an unmanned plane, so as to obtain a suspected landmark image; the landmark positioner performs image processing on the suspected landmark image, so as to obtain the relative height and the relative positioning distance from the unmanned plane to a landmark when the fact that the landmark exists in the suspected landmark image is determined; the main controller is respectively connected with the landmark positioner and the unmanned plane driving equipment, and controls the unmanned plane driving equipment to drive the unmanned plane to be landed on the landmark according to the relative height and the relative positioning distance. The unmanned plane automatic landing system can accomplish automatic and accurate landing of the unmanned plane in various different landforms, and improves the intelligence level of the unmanned plane.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle navigation, in particular to an automatic landing system for unmanned aerial vehicles. Background technique [0002] With the maturity of drone technology and the further expansion of aerial photography technology, in the field of military drone applications, drones are often used in forms of combat support such as reconnaissance and surveillance. More importantly, the application of civilian drones The fields are also becoming more and more extensive, including: photogrammetry, emergency relief, public safety, resource exploration, environmental monitoring, natural disaster monitoring and assessment, urban planning and municipal management, forest fire pest protection and monitoring, etc. [0003] As drones play an increasingly important role in various fields, people's requirements for intelligent flight of drones are also getting higher and higher. Generally speaking, it is more convenie...

Problems solved by technology

However, the equipment of INS is expensive, the accuracy of the simple GPS navigation system is not high, and the inertial navigation system INS, GPS navigation system or INS and GPS integrated navigation system cannot realize the complete intelligence of landing. In addition, the existing UAV landing control It is only limited to landmark finding, positioning and landing on specific terrains, and it is impossible to realize the automatic landing of UAVs in all terrains
