Embodiment 1
[0038] Such as figure 1 As shown, this embodiment provides a method for controlling a display device. The display device to which this method is applicable includes a naked-eye 3D display unit 1 , an image acquisition unit 5 , a gesture recognition unit, and preferably a positioning unit.
[0039] Wherein, the naked-eye 3D display unit 1 refers to any display unit that enables a user to see a three-dimensional 3D image with naked eyes without using 3D glasses.
[0040] Preferably, the naked-eye 3D display unit 1 is any one of a grating type 3D display unit, a prism film type 3D display unit, and a directional light source type 3D display unit.
[0041] The above three types of display units are known glasses-free 3D display units 1 .
[0042] Among them, the grating type 3D display unit is provided with a grating outside the 2D display device. For the left and right eyes of the user, the grating can respectively block different areas of the display device, so that the left an...
Embodiment 2
[0078] This embodiment provides a gesture recognition method, which includes:
[0079] The naked-eye 3D display unit displays a virtual 3D control picture, wherein the virtual distance between the virtual 3D control picture and the user's eyes is equal to a first distance, and the first distance is smaller than the distance between the naked-eye 3D display unit and the user's eyes;
[0080] The image acquisition unit acquires the image of the click action of the user on the virtual 3D control screen;
[0081] The gesture recognition unit judges the click position of the user on the virtual 3D control screen according to the image collected by the image acquisition unit, and sends the control instruction corresponding to the click position to the corresponding execution unit.
[0082] That is to say, the above-mentioned gesture recognition method is not limited to controlling the display device, and it can also be used to control other devices, as long as the gesture recognitio...

Abstract
The invention provides a display device and a control method thereof and a gesture recognition method and belongs to the technical field of gesture recognition. The problem that selection and determination operations in existing gesture recognition must be performed respectively is solved. The display device control method comprises the steps of enabling a naked eye three-dimensional (3D) display unit to display a virtual 3D control picture, enabling a virtual distance between the virtual 3D control picture and a user's eyes to be equal to a first distance, and enabling the first distance to be smaller than the distance between the naked eye 3D display unit and the user's eyes; enabling an image collection unit to collect images of clicking motion on the virtual 3D control picture by the user; enabling a gesture recognition unit to judge the position of clicking on the virtual 3D control picture by the user according to images collected by the image collection unit, and sending control instructions corresponding to the clicking position to a corresponding execution unit. The control method can be used for controlling the display device and is particularly suitable for television control.
Description
technical field [0001] The invention belongs to the technical field of gesture recognition, and in particular relates to a display device, a control method thereof, and a gesture recognition method. Background technique [0002] With the development of technology, it has become possible to control display units (TVs, monitors, etc.) with gestures. A display device with a gesture recognition function includes a display unit for display and an image acquisition unit (camera, camera, etc.) for capturing gestures; by analyzing the captured images, the user's intended operation can be determined. [0003] In the current gesture recognition technology, the "select" and "confirm" operations must be performed separately through different gestures, which is cumbersome to operate. Each time you wave your hand, the station number changes. When the correct station number is selected, you can enter the station through a second gesture (such as waving from top to bottom). That is to say...
