Referring to fig. 1-8, a method for collecting mapping data of an unmanned aerial vehicle comprises the following steps:
s1, fixing a mounting plate 5 and a camera body 51 at the bottom of a rotary disk 41, then driving the unmanned aerial vehicle body 1 to lift up with the camera body 51, and then remotely controlling an adjusting motor 52 to rotate so as to adjust the mapping angle of the camera body 51;
s2, during mapping, the servo motor 43 is remotely controlled to drive the driving gear 44 to rotate, the driving gear 441, the driving gear 44 and the rotary fluted disc 42 are utilized to synchronously drive the rotary fluted disc 42 to rotate, and the camera body 51 can slowly rotate through the speed change function of the driving gear 441 and the driving gear 44, so that mapping data in a mapping range can be better acquired, and the position of the unmanned aerial vehicle body 1 does not need to be adjusted, so that the acquired mapping data are all kept at the same height, and the stability is ensured, and meanwhile, the large-range mapping data acquisition is realized;
s3, when mapping, if the unmanned aerial vehicle body 1 encounters windage and offsets, the first inclination condition is: the counterweight ball 36 will slide along the limiting chute 311 toward the center of the unmanned aerial vehicle body 1, and pull the pull rope 37 to pull the moving magnetic plate 352 to move in a reverse direction toward the inclined side, so as to break the balance between the fixed magnetic plate 351 and the first magnetic plate 34, at this time, the fixed magnetic plate 351 is unchanged from the position, and the moving magnetic plate 352 moves in a direction for weakening the repulsive force, i.e. the moving magnetic plate 352 reduces the repulsive force action on the first magnetic plate 34, so that the repulsive force action of the fixed magnetic plate 351 on the first magnetic plate 34 will be increased, and the counterweight 33 is pushed to move in a reverse direction toward the inclined direction under the repulsive force action; the second tilt condition is: the counterweight ball 36 will slide to one side of the second telescopic rod 39, so that the second telescopic rod 39 is retracted inwards, and the gas inside the second telescopic rod 39 will be filled into the first telescopic rod 38 through the gas guide pipe 381, so that the first telescopic rod 38 extends outwards, so as to push the moving magnetic plate 352 to move towards the counterweight 33, so that the counterweight 33 can move towards the opposite direction of the inclined side under the repulsive force; in summary, when the unmanned aerial vehicle body 1 is deviated, the gravity center of the unmanned aerial vehicle body 1 is quickly changed, so that the unmanned aerial vehicle body 1 is quickly and stably balanced, the stability of the unmanned aerial vehicle body 1 in suspension and staying is ensured, and the accuracy of mapping data acquisition is improved;
s4, finally controlling the unmanned aerial vehicle body 1 to descend, effectively damping the landing rod 24, the supporting rod 22 and the damping spring 23 by means of the arrangement of the landing rod, reducing impact force generated when the unmanned aerial vehicle body 1 descends to the ground, and improving protection of the unmanned aerial vehicle body 1.
