Three-direction angle correction-based unmanned aerial vehicle and correction control method

Abstract

The invention relates to a three-direction angle correction-based unmanned aerial vehicle and a correction control method thereof. The three-direction angle correction-based unmanned aerial vehicle comprises a vehicle body, three vehicle arms connected with the vehicle body, rotor wing and power device assemblies corresponding to the three vehicle arms, and an angle correction device; the angle correction device comprises a first measuring device, a second measuring device, a third measuring device and a calibrator; the first measuring device, the second measuring device and the third measuring device are respectively arranged on the three vehicle arms through connecting rods; the first measuring device, the second measuring device and the third measuring device can be respectively accommodated in the three vehicle arms after being contracted; the calibrator is arranged on the vehicle body through a flexible connecting wire and can be accommodated inside the vehicle body; the outer walls of the housings of the first measuring device and the second measuring device are provided with a distance measuring sensor separately; the calibrator is provided with scale marks and a sensor which is used for sensing signals and recording a sensing position in real time; and the lower end of the calibrator is provided with a calibration sensor. With the three-direction angle correction-based unmanned aerial vehicle and the correction control method thereof of the invention adopted, measurement accuracy can be improved; after the change trend of a tilt angle is accurately measured, the angle correction of the flight device can be performed; and therefore, monitoring efficiency can be improved, and monitoring accuracy can be also improved.

Description

technical field [0001] The invention relates to the field of measurement, in particular to an unmanned aerial vehicle based on three-way angle correction and a correction control method. Background technique [0002] This year, with the development of social economy and science and technology, aviation technology has received extensive attention in the military and civilian fields. Future aviation technology is also an important development trend. With the development of aviation technology, more and more technological equipment can be loaded in UAVs, such as monitoring and sensing equipment, communication equipment, positioning equipment, shooting equipment, etc., which are widely used in the field of aviation technology. [0003] Among them, through the equipment loaded in the UAV, it is possible to monitor the image on the ground, measure the height in the air, etc., and different altitudes have different monitoring environments, and unexpected measurement angles (such a...

Problems solved by technology

However, when UAVs are currently monitoring the ground, due to the influence of the external environment (such as wind, air pressure, altitude, etc.), it is often impossible to use equipment such as cameras to take accurate pictures at the desired angle.

Although there are measuring devices such as gyroscopes for angle measurement in the prior art, so as to realize angle correction equipment, it still cannot meet the requirements of high-precision measurement.
