Problems solved by technology

Because in the prior art, the user inputs or frames the location area of ​​the target to be tracked, and when the target object is too small or the target object is in motion, it is difficult for the user to input or frame the exact location area of ​​the target to be tracked, increasing It increases the difficulty of user operation, affects the accuracy of target area determination, and then affects the accuracy of tracking.

Embodiment 1

[0058] figure 1 A schematic diagram of a target tracking process provided by an embodiment of the present invention, the process includes the following steps:

[0059] S101: Acquire an image of a currently tracked target object.

[0060] The target tracking method provided by the embodiment of the present invention is applied to a drone. During the process of tracking the currently tracked target object, the UAV acquires the image of the currently tracked target object.

[0061] The unmanned aerial vehicle of the embodiment of the present invention is provided with a cloud platform, and the cloud platform can rotate 360 ​​degrees around the rotating shaft relative to the drone body. Turn up. The image acquisition device can perform image acquisition in real time, and the image currently collected by the image acquisition device is the currently tracked image including the target object acquired by the drone.

[0062] S102: Receive an operation of clicking a target object, ...

Embodiment 2

[0071] In order to make the determination of the target area in the image more accurate, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, after acquiring the image of the currently tracked target object and before receiving the operation of clicking the target object, the method further include:

[0072] Identify various regions in the image.

[0073] After the UAV acquires the image of the currently tracked target object, it can automatically determine each area in the image. After determining each area in the image, it receives the operation of clicking the target object, and according to the operation of clicking the target object corresponds to The area in the image can be used to determine the target area.

[0074] In an embodiment of the present invention, the determination of each area in the image includes:

[0075] A. For each pixel in the image, use an image segmentation algorithm to determine the frame selection area in ...

Embodiment 3

[0127] In order to make the determined target area more accurate, on the basis of the above embodiments, in the embodiment of the present invention, the determining the target area in the image according to the click operation includes:

[0128] Identify the coordinates of the first pixel of the display interface corresponding to the click;

[0129] judging whether the coordinates have an assigned area;

[0130] If yes, and the coordinates only belong to one area, the area to which the coordinates belong is taken as the target area;

[0131] Otherwise, output a prompt message indicating that the target object failed to be selected.

[0132] When determining the target area in the image according to the click operation, the UAV can identify the coordinates of the first pixel of the display interface corresponding to the click operation, since the merged area has been determined in the image, The coordinates of the pixels in the merged area can be identified by the drone. Ther...

Abstract

The invention discloses a target tracking method, device and system, which is used for accurately identifying a target object in an image, and improves the tracking accuracy. The method comprises thesteps of acquiring the image of the currently tracked target object; receiving an operation of clicking the target object, and determining a target region in the image according to the clicking operation; and tracking the target region. According to the target tracking method, device and system, an unmanned aerial vehicle receives the operation of clicking the target object, determines the targetregion in the image according to the clicking operation, and tracks the target region, so that the accuracy of the determined target region and the tracking accuracy can be ensured.

Description

technical field [0001] The present invention relates to the technical field of UAV tracking, in particular to a target tracking method, device and system. Background technique [0002] In the past ten years, UAVs have been widely used in disaster assessment, rescue and relief, on-site reconnaissance, military exercises and other fields. In aerial photography, if UAVs can quickly and accurately obtain images containing target objects, they can be Realize the tracking of the target object, so that the real situation of the target object can be understood more quickly, timely and comprehensively. [0003] When the existing target object is tracked based on the image containing the target object, in general, the user inputs the location area of ​​the target object to be tracked, or selects the location area of ​​the target object in the image, and will track the target object The location area is sent to the UAV, and the UAV determines and tracks the target area according to th...
