Embodiment 1

[0081] Embodiment 1 of the present invention provides a video terminal control method. By collecting the trajectory image of the moving object, the trajectory feature information of the selected feature point on the moving object is determined, so as to obtain the corresponding input information, and then obtain the operation instruction corresponding to the input information. , realize the interpretation and recognition of the trajectory of the moving object, determine the various input information, and correspond to the operation instructions, so as to meet the input control of various possible operation instructions. The process is as follows figure 1 shown, including the following steps:

[0082] S11: Acquiring the track image of the moving object according to the set acquisition frequency.

[0083] When the moving object of the input command is captured, the trajectory image of the moving object is collected according to the set collection frequency. For example, when t...

Embodiment 2

[0097] The video terminal control method provided by Embodiment 2 of the present invention collects three-dimensional position information of selected feature points on a moving object, and then converts it into two-dimensional position information, so as to realize accurate collection of multi-directional input information and make the control of the video terminal more accurate. Flexible and more convenient to operate, the method flow is as follows figure 2 shown, including the following steps:

[0098] S21: When the moving object of the input information is captured, the trajectory image of the moving object is collected according to the set collection frequency.

[0099] See step S11 for details.

[0100] In this embodiment, the binocular camera is taken as an example. The binocular camera can obtain the depth of field information, so that other interference information can be removed, and the three-dimensional position information such as the three-dimensional space coo...

Embodiment 3

[0172]The video terminal control method provided by Embodiment 3 of the present invention executes different operation processes according to the set current mode, such as terminal control or trajectory model training, and its process is as follows Figure 7 shown, including the following steps:

[0173] S31: When the moving object of the input information is captured, the track image of the moving object is collected according to the set collection frequency.

[0174] Refer to step S11 and step S21, which will not be repeated here.

[0175] S32: Determine the location information of the selected feature points on the moving object in each of the collected trajectory images, and obtain the trajectory feature information of the selected feature points of the moving object according to the determined location information.

[0176] Refer to step S11 and step S23-step S25, which will not be repeated here. It should be noted that, before performing this step, the data preprocessi...

Abstract

The invention discloses a method and a device for controlling a video terminal and the video terminal. The method includes acquiring track images of moving objects according to a set acquisition frequency; determining position information of selected feature points on the moving objects in the acquired track images and obtaining track feature information of the selected feature points according to the determined position information; matching the obtained track feature information of the selected feature points with a preset track model of input information to obtain input information of the moving objects; and controlling the video terminal to execute corresponding operations according to operational orders corresponding to the input information. By means of the method and the device for controlling the video terminal, all kinds of information input by gestures can be recognized, control over the video terminal is achieved, the operation is flexible, and the generality is high.

Description

[0001] technical field [0002] The invention relates to the technical field of video control, in particular to a method and device for controlling a video terminal, and a video terminal. [0003] Background technique [0004] At present, the user needs to realize the control of the TV, including various operation controls such as channel switching and function switching, and generally needs to be realized through a remote control. Realize controlling the TV to display different channels or switch to different functions. [0005] With the increase in TV functions and the increase in the number of channels, the number of buttons that need to be set on the remote control is also increasing. In this way, whenever a new function is added, new buttons need to be set on the remote control, which also increases the number of buttons on the remote control. The complexity of device design and the cost of replacement are not conducive to the realization of human-computer interaction...
