Problems solved by technology

[0003] Mobile phone APP control requires the use of low-cost micro-electromechanical sensors in smartphones. Large measurement errors will cause large attitude estimation errors, resulting in increased flight instability of UAVs during somatosensory control. At the same time, today's commercial The mobile phone APP control scheme is only applicable to a specific series of drones and is not universal

Embodiment Construction

[0045] The present invention will be further described below in conjunction with the description of the drawings and specific embodiments.

[0046] like figure 1 Shown, a kind of UAV mobile phone APP control method that supports ROS, comprises the following steps:

[0047] S1, sensor calibration;

[0048] S2, attitude estimation;

[0049] S3, wireless data transmission;

[0050] S4. Aircraft control.

[0051] like figure 1 As shown, a ROS-supporting UAV mobile phone APP control method provided by the present invention is mainly divided into four parts: sensor calibration part, attitude estimation part, wireless transmission part and aircraft control part. The sensor calibration part mainly includes magnetometer calibration, accelerometer calibration and gyroscope calibration; the attitude estimation part is mainly used to estimate the attitude of the smartphone; the wireless transmission part is mainly used to transmit flight instructions between the mobile phone and the UA...

Abstract

The invention provides a mobile phone APP control method of an unmanned aerial vehicle supporting an ROS. The control method comprises the following steps: S1, sensor calibration; S2, posture estimation; S3, wireless data transmission; and S4, unmanned aerial vehicle control. The control method provided by the invention has the advantages that all unmanned aerial vehicles supporting the ROS can becontrolled, the operation is simple, the portability is high, the cost is low, and the university is high; the posture of the smart phone can be accurately estimated, and the unmanned aerial vehiclecan be controlled through stable somatosensory system.

Description

technical field [0001] The present invention relates to unmanned aerial vehicle, relate in particular to a kind of APP control method of unmanned aerial vehicle mobile phone supporting ROS. Background technique [0002] UAVs are widely used in aerial photography, military, agriculture and other fields, and are now gradually expanding to the field of personal consumption. For example, the Spark drone released by DJI, a leading drone company, in June 2017 is small in size and light in weight, and mainly meets the needs of ordinary people for taking selfies. For small UAVs in the personal consumption field, the control modes mainly include remote control and mobile APP control. DJI's Spark UAV supports remote control and mobile APP control, which can not only meet the needs of close-range selfies, but also realize the needs of mid-range aerial photography. The DOBBY pocket drone of Zero Degree Intelligent Control only supports mobile phone APP control, including somatosensory...
