Problems solved by technology

The main disadvantage of the optical flow method is that it has a large amount of calculation and is easily affected by noise and light. Therefore, the optical flow method is not suitable for use in the tracking of moving targets by drones.
None of the existing methods for tracking targets by UAVs can track moving targets in total darkness

Embodiment 1

[0029] see figure 1 , in an embodiment of the present invention, a system for tracking a target by an unmanned aerial vehicle is composed of a zoom CCD camera, a zoom laser light supplement, a pan / tilt control unit, an intelligent analysis unit, and a flight control unit; a zoom CCD camera, a zoom laser light supplement The controller performs data interaction with the gimbal control unit, the gimbal control unit performs data interaction with the intelligent analysis unit, and the intelligent analysis unit performs data interaction with the flight control unit.

[0030] The pan-tilt control unit can control the zoom CCD camera and the zoom laser fill light device to rotate 120 degrees in the vertical direction and 360 degrees in the horizontal direction and can control the zoom CCD camera to zoom.

[0031] The zoom CCD camera adopts optical zoom method to zoom, which can make the image without loss in the whole focal length range.

[0032] The zoom laser fill light device us...

Abstract

The invention discloses an unmanned aerial vehicle target tracking method and system. The method includes that an image capture unit comprises a zooming CCD camera and a zooming laser light supplement device, and the zooming laser light supplement device is used for supplementing light for the monitored region of the zooming CCD camera to allow the zooming CCD camera to acquire sharp images of the monitored region; a pan tilt control unit controls the pan tilt in horizontal and vertical directions and the focal distance of the zooming CCD camera to allow a tracked target to be in the center of the vision of the zooming CCD camera constantly; an intelligent analysis unit adopts the method of extracting a moving target from the gray level image sequence and detects the moving target from the images; after extraction and positioning of the moving target, a flying control unit feeds the moving state of the target back to an unmanned aerial vehicle, and the unmanned aerial vehicle flies to track the ground dynamic target automatically. The method has the advantages that the visual distance is long, and the unmanned aerial vehicle is capable of tracking a moving target in a completely dark environment.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and system for an unmanned aerial vehicle to track a target. Background technique [0002] A drone is an unmanned aerial vehicle operated by a radio remote control device or its own program control device. With the continuous improvement of the technical level, UAVs have been widely used in intelligence reconnaissance, communication relay, armed strike, target tracking, search and rescue and other fields. Existing UAVs often use a fixed focal length CCD photoelectric camera to monitor the flight area in real time, and can obtain high-resolution image information. After the image information is compressed, it is transmitted back to the ground through a 433MHz radio frequency signal, and the ground is then decompressed. Restore the original monitoring image to realize the monitoring of specific areas. [0003] In order to track the target of interest during ...
