The invention discloses an unmanned aerial vehicle for geographic information data acquisition, which comprises a fuselage, a driving motor is mounted on the fuselage, the driving motor is connected with a propeller, and a damping mechanism is mounted on the outer side of the driving motor; the vibration reduction mechanism comprises a mounting hole formed in the machine body, a plurality of outer supporting pieces are annularly fixed to the inner side of the mounting hole, the bottoms of the outer supporting pieces are obliquely arranged towards the center of the mounting hole, a through hole is formed in the center of the bottom of the mounting hole, and a threaded hole matched with the through hole is formed in the bottom of the driving motor. The fixing bolts penetrate through the through holes and then are in threaded connection with the threaded holes, inner supporting pieces in one-to-one correspondence with the outer supporting pieces are fixed to the outer side of the driving motor, the outer supporting pieces are parallel to the inner supporting pieces, rubber layers are fixed to the inner sides of the outer supporting pieces and the outer sides of the inner supporting pieces respectively, and the rubber layers on the outer supporting pieces make contact with the rubber layers on the inner supporting pieces. According to the invention, the defects in the prior art can be overcome, and the anti-interference capability of airborne camera imaging on high-frequency vibration is improved.
