after the above process is finished, the topographic survey camera 10 is vertically downward, i.e. perpendicular to the ground, when the unmanned aerial vehicle 1 advances or turns according to the demand of topographic survey for adjusting the homeland space plan, the unmanned aerial vehicle 1 will generate a forward tilt or an inclined forward tilt, the topographic survey camera 10 will autonomously generate adjustment according to the situation, and the specific analysis is as follows:
if the unmanned aerial vehicle 1 advances linearly, the unmanned aerial vehicle 1 will incline forward, at this moment, the rotating plate 4 and the cross rod 5 will incline forward synchronously along with the unmanned aerial vehicle 1, thereby make the guide frame 12 on the cross rod 5 incline, initially, the guide frame 12 drives the terrain measurement camera 10 to incline through the first connecting rod 9 and the second connecting rod 11, the inclined upward supporting force of the guide frame 12 to the first connecting rod 9 and the second connecting rod 11 Shi Jiatong is generated by the inclined rear guide frame 12, at this moment, the resultant force of the terrain measurement camera 10 is horizontal, the terrain measurement camera 10 rotates, after the rotation of the terrain measurement camera 10, the supporting force of the guide frame 12 to the first connecting rod 9 changes direction, the inclined direction is reversed, but the supporting force of the first connecting rod 9 is less than the supporting force of the second connecting rod 11, the terrain measurement camera 10 continues to turn until the supporting force of the first connecting rod 9 = the supporting force of the second connecting rod 11, at this moment, the terrain measurement camera 10 stops rotating, the first connecting rod 9, the second connecting rod 11 and the guide frame 12 form an isosceles right triangle, and the terrain measurement camera 10 is vertically downward again, namely vertical to the ground.
II, if the unmanned aerial vehicle 1 forwards, the unmanned aerial vehicle 1 will incline forward, the inclined forward incline process is that the unmanned aerial vehicle 1 inclines transversely after inclining forward, the forward incline is the same as the analysis, the unmanned aerial vehicle 1 transversely rotates during the transverse incline, the gravity center of the terrain measurement camera 10 is positioned below the first connecting rod 9 and the second connecting rod 11, the rotating point of the rotating plate 4 is positioned right above the circle center of the rotating plate 4, so that the whole gravity centers of the terrain measurement camera 10, the rotating plate 4 and the cross rod 5 are positioned below the rotating point of the rotating plate 4, the rotating plate 4 can also reset after inclining transversely, and the terrain measurement camera 10 is vertically downwards again, namely, is vertical to the ground.
In summary, the topography measurement camera 10 can be kept downward all the time, and even if the unmanned aerial vehicle 1 advances or turns, the topography measurement camera 10 will not incline randomly, so that the topography measurement camera 10 is always perpendicular to the bottom surface, and the measurement quality of the topography measurement camera 10 for planning topography in the homeland space can be ensured.
After the topographic survey for adjusting the homeland space planning is finished, the unmanned aerial vehicle 1 falls vertically, the motor 15 is reversely started, the motor 15 drives the movable block 17 to return through the screw rod 16, the second embedded block 18 on the movable block 17 is embedded with the first embedded block 8 again, the operation is reversely repeated, the topographic survey camera 10, the baffle 35 and the telescopic frame 36 are restored to the initial state again, the closing of the photographic part and the closing of the protecting device are synchronously performed, the requirement on the subjective activity of a user is further reduced, the protecting device is prevented from being not closed due to forgetting, the photographic part can be fully protected, the effect of the protecting device is further improved, and the operation is finished.
