Abstract

The invention provides an intelligent course control method for a UAV, including: self-checking when the UAV is powered on, recording the course and GPS coordinates in the northeast coordinate system at the take-off point, and taking off in the normal remote control mode; selecting the initial course to lock mode or home point lock mode; if the initial course lock mode is selected, the aircraft course at the take-off point will be used as the initial course, and the intelligent course control will be realized in the Cartesian coordinate system of the origin of the take-off point; if the home point lock mode is selected, then Intelligent heading control is realized under polar coordinates with the take-off point as the pole. According to the intelligent course control method of the UAV in the embodiment of the present invention, it can effectively reduce the crash or loss of the UAV caused by the unskilled operation of the controller or the flight distance is too far to judge the current course. Greatly simplifies the operation of drones and improves their flight safety.

Description

Technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an intelligent heading control method for unmanned aerial vehicles. Background technique [0002] UAVs are widely used in military and civilian fields because of their low cost-effectiveness, rapid deployment and zero casualties. Controllers control the flight actions of UAVs through traditional remote control operations, which can play an important role in disaster scene monitoring, aerial photography, search and rescue, and infrastructure monitoring. [0003] UAV heading control in traditional remote control means that in normal (no smart heading) mode, the forward direction of the joystick corresponds strictly to the forward direction of the drone head. Flight action. There are big problems with this traditional control method. On the one hand, when the controller is not familiar with the drone control, it is easy to cause the drone's heading to be confused and ca...
