The invention discloses an unmanned aerial vehicle long-distance real-time positioning mapping display
interconnection type control method, which comprises: determining the
longitude, the
latitude and the altitude of an unmanned aerial vehicle position, and the
azimuth angle and the
pitch angle of a camera; determining the altitude of a center point and the liner distance between the center point and the upright projection point of the unmanned aerial vehicle on the ground according to the
linear distance between the unmanned aerial vehicle and the center point, wherein the
linear distance between the unmanned aerial vehicle and the center point is determined by the
laser distance measurement instrument on the unmanned aerial vehicle; determining the geographical coordinates of the center point by using a
latitude and
longitude calculation formula; calculating the true width and the true height of the visual field in the
camera image by using a trigonometric function theorem according to the altitude of the unmanned aerial vehicle and the
pitch angle, and determining the coordinates of other points by combining with the coordinates of the center point and the screen pixel resolution; and defining multiple marking points, calculating the distances between different marking points, and calculating the area of the polygon formed from the marking point by using a Heron's formula. According to the present invention, with the method, the positioning of the geographical coordinates of the any target point in the long-distance real-time video can be achieved, the altitude is determined, and the visual field area is determined.
