Embodiment Construction

[0053] The present invention is described in detail by the following examples. It is necessary to point out that this example is only used to further illustrate the present invention, and can not be interpreted as limiting the protection scope of the present invention. Those skilled in the art can according to the above invention Some non-essential improvements and adjustments have been made to the content. In the case of no conflict, the embodiments and the features in the embodiments of the present invention can be combined with each other.

[0054] At a certain moment, when both UAVs have finished tracking the target, the UAV can return the azimuth and elevation values ​​of its line of sight in the UAV body coordinate system. The line of sight must be pointed to the target by the drone, so the intersection of the two lines of sight is the target.

[0055] The spatial analysis method of line-of-sight intersection can obtain the spatial coordinates of the target by calculati...

Abstract

The present invention discloses a dual-unmanned aerial vehicle distance measurement method. Two unmanned aerial vehicles equipped with optoelectronic tracking devices are configured to track an objectat the same time and transmit orientation values and pitching values of lines of sight to a ground control system, and the ground control system uses a space analytical algorithm to obtain coordinates of the object. The dual-unmanned aerial vehicle distance measurement method employs the two unmanned aerial vehicles to track the object at the same time to obtain the position of the object in a three-dimensional space through the space analytical algorithm so as to solve the problem that a distance of distance measurement is near and power supply is needed when a laser echo distance measurement method performs object space positioning.

Description

technical field [0001] The invention relates to the technical field of spatial analysis tracking and ranging, in particular to a method for tracking and ranging of dual drones. Background technique [0002] In recent years, the development of drones has been extremely rapid. The civilian rotor UAV is easy to fly and recover, and the price is cheap. It can carry photoelectric tracking equipment (such as a TV tracker) and navigation and positioning equipment. After installing a laser ranging device, the rotor UAV can track and measure space targets and determine the target. Spatial location. However, limited by the load capacity of the rotor UAV, it is difficult to mount the heavy mid-range and long-range laser ranging equipment on the rotor UAV, which greatly limits the target tracking distance of the rotor UAV. Contents of the invention [0003] In order to solve the problem that the laser echo ranging method has a short ranging distance and needs power supply in the tar...
