Title:
OPTICAL CONTROL METHOD AND SYSTEM FOR AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2017/124840
Kind Code:
A1
Abstract:
An optical control method and system for an aircraft. The optical control method for an aircraft (2) comprises: S1, setting a plurality of mark points (6) on the aircraft (2), establishing a 3D cartesian coordinate system which always takes a flight controller (1) with a shooting apparatus (101) as an origin; S2, when the aircraft (2) is in a reference flight posture, photographing the aircraft (2) and extracting projections of a graph enclosed by the plurality of mark points (6) in an image on three coordinate planes of the coordinate system as reference projection graphs; S3, photographing the aircraft (2) in real time, extracting projections of the enclosed graph in the photographed image respectively on the three coordinate planes respectively as real-time projection graphs, analysing the deflection of the real-time projection graph on each coordinate plane with respect to the reference projection graphs, so as to get a real-time posture, and working out the position of the aircraft (2) in the coordinate system according to the mark points (6); and S4, after receiving a flight control instruction, adjusting flight parameters of the aircraft (2) and controlling the flight of the aircraft (2), according to the position and the posture of the aircraft (2).
