Unmanned aerial vehicle orientation adjusting method and system

The invention provides an unmanned aerial vehicle orientation adjusting method. The unmanned aerial vehicle orientation adjusting method comprises the steps that an unmanned aerial vehicle records current longitude and latitude coordinates of the unmanned aerial vehicle and current longitude and latitude coordinates of a controller; the unmanned aerial vehicle receives an angle adjusting command and calculates adjusted longitude and latitude coordinates by taking the longitude and latitude coordinates of the controller which sends out the angle adjusting command as a circle center according to the current longitude and latitude coordinates of the unmanned aerial vehicle and a rotation angle; the unmanned aerial vehicle leaves for the position positioned by the adjusted longitude and latitude coordinates. According to the unmanned aerial vehicle orientation adjusting method, by presetting a rotation flying program in the unmanned aerial vehicle, the unmanned aerial vehicle can quickly calculate the coordinate position of the rotated coordinates and fly to the position to complete angle rotation after receiving the angle deflection command sent by the controller.
