METHOD OF OBSERVATION OF OBJECTS FROM REMOTELY-PILOTED FLYING VEHICLE, REMOTELY-PILOTED FLYING VEHICLE AND ITS OBSERVATION FRAME-TYPE SYSTEM Russian patent published in 2006 - IPC B64D47/08 

FIELD: unmanned flying vehicles used for air observation of areas and objects located on them.

SUBSTANCE: observation is carried out with the aid of frame-type observation system. Image of object is transmitted from remotely-controlled flying vehicle at present time. In the course of observation, cameras of frame-type observation system with different fields of vision are changed-over. Flying vehicle is controlled in heading holding the image of object in vertical center line of frame. Cameras are changed-over when images of one field of vision of one camera shift to field of vision of next camera. When image gets in field of vision with narrower field of vision, frame is stored. Coordinates of object are calculated by position of image in stored frame, coordinates and angles of orientation of flying vehicle. Flying vehicle has fuselage, wing or another lifting system, power plant, control system with command radio line receiver, frame-type observation system and information signal transmitting system. Frame-type observation system consists of one or more TV and/or infra-red cameras; this system is arranged inside fuselage. Optical axes of cameras are fixed in plane of vertical symmetry of flying vehicle and are oriented forward and downward at different angles from 0 to 90° relative to its vertical axis. Fields of vision of cameras have different width. Cameras with more sloping orientation of optical axes have equal or wider field of vision as compared with cameras at lesser sloping of orientation.

EFFECT: reduced mass and overall dimensions and cost at simultaneous enhanced aerodynamics.
