UAV based on four-way angle correction and calibration control method thereof

Abstract

The invention provides a UAV based on a four-way angle correction and a calibration control method thereof. The UAV includes a machine body, four machine arms connected with the machine body, corresponding rotor and power devices thereof, and an angle correction device. The angle correction device comprises first, second, third and fourth measuring devices and a calibrator, the first, second, third and fourth measuring devices are respectively disposed on the four machine arms through connecting rods respectively, and the first , second, third and fourth measuring devices can respectively be retracted and accommodated in the four machine arms. The calibrator is disposed on the machine body through a flexible connecting wire, and the calibrator can be accommodated inside the machine body. A distance measuring sensor is respectively arranged on the outer wall of the outer shell of each of the first and the second measuring devices, and the calibrator has a scale and is provided with inductors for sensing signals and timely recording sensing positions. The lower end of the calibrator is provided with a calibration sensor to improve the measurement precision. The angle correction of flight equipment is performed after precise measurement of the inclination angle change trend, so that the monitoring efficiency is improved and the monitoring precision is improved.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a UAV based on four-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 as tilt) will make If ...

AI Technical Summary

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.
