Embodiment 1

[0031] figure 1 It is a schematic flow chart of a method for target tracking control in an embodiment of the present invention, see figure 1 , including the following steps:

[0032] Step S101, adding an instruction for acquiring the position information of the tracked target in real time and following the position movement of the target object in the target object of the tracked target;

[0033] Step S102, control and adjust the position of the shooting device according to the acquired position information of the target, so that when the position of the target moves, the focus of the shooting device tracks the movement of the target and shoots the target in real time, and when the target rotates, the focus of the shooting device does not track the target turn.

[0034] Depend on figure 1 As can be seen from the method shown, in this embodiment, an instruction for obtaining the location information of the tracked target in real time and following the position movement of th...

Embodiment 2

[0036] In this embodiment, the implementation details of the object tracking control method of the present invention are focused on description.

[0037]In Unity3D, in order to clearly display the position of the positioning and tracking target, first, move the viewpoint of the camera to a suitable viewing angle and position, and then position and track the observed target. Because the angle of view movement is a transition effect, there is a certain animation transition time, and during the movement of the angle of view, the target may also move, so that the target cannot be located and observed after the angle of view is moved. Ensure accurate positioning of the target and follow the target position and the camera angle of view does not follow the target rotation.

[0038] The overall implementation process of the target tracking control in the embodiment of the present invention: firstly, without changing the height of the camera, the camera moves to a position obliquely ab...

Embodiment 3

[0062] A device for target tracking control is provided in this embodiment, and the device 20 for target tracking control includes:

[0063] The position information acquisition unit 201 is used to add an instruction for acquiring the position information of the tracked target in real time and following the position movement of the target object in the target object of the tracked target;

[0064] The tracking control unit 202 is configured to control and adjust the position of the shooting device according to the acquired position information of the target, so that when the position of the target moves, the focus of the shooting device tracks the movement of the target and shoots the target in real time, and when the target rotates, the focus of the shooting device Focus does not track target rotation.

[0065] In one embodiment of the present invention, the location information acquisition unit 201 is specifically configured to find the class of the tracked target, and insta...

Abstract

The invention discloses a method and device for target tracking control. The method includes: adding an instruction for acquiring the position information of the tracked target in real time and following the position movement of the target object in the target object of the tracked target; The position information of the target is controlled to adjust the position of the photographing device, so that when the position of the target moves, the focus of the photographing device tracks the movement of the target and photographs the target in real time, and when the target rotates, the The focus of the camera device does not track the target rotation. In the method and device for target tracking control of the present invention, an instruction to maintain consistency in position movement is added to the target object, so that when the position of the target moves, the camera observation point always takes the tracking target as the focus center, and since there is no The shooting device is assigned as a sub-object of the tracked target, which also solves the problem that the camera rotates following the tracked target.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for target tracking control. Background technique [0002] Unity3D is a multi-platform comprehensive development developed by Unity Technologies that allows users to easily create interactive content such as 3D video games, architectural visualization, and real-time 3D animation. In the prior art, Unity3D provides a mechanism to realize object positioning and tracking, that is, the tracking object is assigned as a sub-object of the tracked object, so that when the tracked object moves or rotates, since the tracking object is a sub-object of the tracked object Object, so the tracked object will also move or rotate with the tracked object. However, in the target positioning and tracking based on Unity3D, the existing solutions have at least the following defects: [0003] Deficiency 1: Since the position of the camera's viewpoint is not fixed when the positi...
