Title:
FLIGHT POSITIONING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/027451
Kind Code:
A1
Abstract:
A flight positioning method and device. The flight positioning method comprises: acquiring a target region image (11); identifying a predetermined marker in the target region image, wherein the predetermined marker is marked with two-dimensional coordinate information used to identify two-dimensional coordinates of the predetermined marker (12); determining, according to the two-dimensional coordinate information, two-dimensional coordinates of an aircraft (13); and determining, according to a distance sensor or according to a pixel width of the predetermined marker and a correspondence relationship between pixel widths of the predetermined marker and a flying height, a flying height of the aircraft (14). The flight positioning method of the present invention enables determination of three-dimensional coordinates of an aircraft, thus realizing accurate positioning during flight for an aircraft.
