An unmanned aerial vehicle based on angle correction and its correction control method

Abstract

The invention discloses an unmanned aerial vehicle based on angle correction and a correction control method. The unmanned aerial vehicle based on angle correction comprises a vehicle body, four vehicle arms connected with the vehicle body, corresponding rotors, power devices, and an angle correction device, wherein the angle correction device comprises a measurement device and a calibrator; the measurement device is arranged on one vehicle arm through a connection rod; the measurement device comprises a shell, a base, a first distance measurement unit, a second distance measurement unit and a third distance measurement unit; the outer wall of the shell is provided with a distance measurement sensor; the setting position of the distance measurement sensor is flush with the lower edge of the calibrator in the horizontal direction; the calibrator has a scale and is provided with a sensor for sensing signals transmitted by the distance measurement sensor in a scale range and recording the sensing position in real time; and the lower end of the calibrator is provided with a calibration sensor for measuring the vertical distance between the calibrator and the ground. Thus, the measurement precision can be improved, angle correction on flight equipment can be carried out after the tilt angle change trend is measured precisely, the monitoring efficiency is thus improved, and the monitoring precision is improved.

Description

technical field [0001] The invention relates to the field of measurement, in particular to an angle correction-based unmanned aerial vehicle 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 ...

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.
