Mooring unmanned aerial vehicle optical positioning system based on annular laser target and solid-state camera

The invention discloses a mooring unmanned aerial vehicle optical positioning system based on an annular laser target and a solid-state camera. The system comprises the annular laser target deployed on a mooring unmanned aerial vehicle, and a light aiming device and a calculation positioning module which are deployed on a ground control station; wherein the light aiming device comprises a solid-state camera; the annular laser target is used for providing a measurement reference of an air-ground slant distance R and a measurement reference of relative orientation alpha and pitching beta of the mooring unmanned aerial vehicle for the solid-state camera; the light aiming device is used for imaging the annular laser target through the solid-state camera to obtain a coordinate value of the annular laser target on a target surface of the solid-state camera; and the resolving and positioning module is used for resolving the coordinate values according to the optical geometrical relationship to obtain the position in
