A fast mapping and plotting method of multi-rotor UAV

The present invention discloses a mapping method for mapping a fast multi-rotor UAV, belonging to the field of aviation technology mapping. The present invention includes a frame, a lifting mechanism flight, pan and tilt mechanism and a control mechanism, the rack extending along the machine body four arms, the lower body is provided with a stand, the stand arm and the machine are collapsible structure, lifting flight means the arm is provided at the end of four, the mount head means mounted at the bottom of the rod body UAV, means mounted on a camera head, camera pan and tilt mechanism for adjusting the optical axis is always perpendicular to the ground, using the control means UAV flight control and adjust the pedestal to a specified height reversing mechanism; mapping method of the present invention by analyzing the camera lens parameters, determining the relationship between the photographing height and the imaging scale, reset UAV flight path. The present invention can be obtained quickly mapping a result, high accuracy and efficiency mapping.
