Problems solved by technology

However, there is no good tracking method for targets with non-uniform speed and non-directional movement.
If the UAV does not follow the target movement, the UAV will lose the detection of the target after the target leaves the observation range of the optoelectronic platform

Abstract

The invention discloses a target tracking route generation method based on an unmanned aerial vehicle and a photoelectric platform, and belongs to the technical field of unmanned aerial vehicles. The method comprises the following steps of: acquiring unmanned aerial vehicle parameters, photoelectric platform parameters and distance measurement information at a target positioning moment; calculating the longitude, latitude and height of a target; generating a circular or rectangular tracking air route, and making the unmanned aerial vehicle automatically fly according to the tracking air route; judging whether the target needs to be positioned again or not in the flight process of the tracking route; and generating an air route according to new positioning information, uploading the air route, performing comparing, and enabling the unmanned aerial vehicle to fly according to the new tracking air route so as to dynamically track the target. The method is based on the unmanned aerial vehicle and the photoelectric platform, the longitude, latitude and height of the target are calculated according to the remote measurement information of the unmanned aerial vehicle and the laser ranging value of the photoelectric platform, and the air route for the tracking the target is automatically generated according to the target position information.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method for generating a target tracking route based on an optoelectronic platform of an unmanned aerial vehicle. Background technique [0002] It is an important research topic for the application of UAVs to continuously track the discovered targets. For example, applications such as continuous tracking of moving vehicles and personnel, continuous observation of oil pipeline leakage areas, and continuous observation of fire spread trends in forest areas all require drones to provide a stable observation angle for the payload platform. This puts high demands on the flight path of UAVs. [0003] The optoelectronic platform selects the current domestic mature three-light (visible light, infrared, laser) optoelectronic pod. The functions of the photoelectric pod mainly include visible light / infrared video acquisition, laser irradiation, target recognition, etc. ...
