Embodiment 1

[0082] The tracking naked-eye stereoscopic display control method in this embodiment includes a display parameter adjustment process, such as Figure 5 shown, including:

[0083] Step 110, determine the current viewing distance of the viewer;

[0084] If the user's position captured by the tracking device is outside the viewing range allowed by the stereoscopic display, the user is not considered a viewer and his position data is discarded.

[0085] For a dual-viewpoint system, the current viewing distance of the viewer can be determined according to the three-dimensional coordinate information (Z-axis coordinate) of the viewer calculated by the tracking device. For a multi-viewpoint system, the viewing distances of multiple viewers need to be considered. For example, the average viewing distances of all viewers can be used as the current viewing distance, but the present invention is not limited to any specific determination method.

[0086] The current viewing distance deter...

Embodiment 2

[0111] The adjustment process of the display parameters by the tracking type naked-eye stereoscopic display control method in this embodiment is slightly different from that in the first embodiment. Figure 9 As shown, the adjustment process includes:

[0112] Step 210, determine the current viewing distance of the viewer, same as step 110;

[0113] Step 220, from the selected multiple display parameter combinations that include the width of the spectroscopic unit and the display unit arrangement period, select a corresponding display parameter combination that is equal to or adjacent to the current viewing distance, and select a display parameter combination in the display parameter combination. The display parameter of is determined as the target display parameter;

[0114] This step can also include:

[0115]Step 1: Divide the viewing distance range allowed by the stereoscopic display device into a plurality of continuous sections, each section includes an optimal viewing...

Abstract

The invention discloses a tracking type autostereoscopic display control method, a tracking type autostereoscopic display control device, a tracking type autostereoscopic display control system and display equipment. The tracking type autostereoscopic display control method comprises a process for adjusting a display parameter, wherein the process comprises the following steps of: determining the current watching distance of a watcher; and performing joint adjustment on a synthesis parameter of a stereo image and a light split parameter of a controllable light splitter to adjust a watching adaptation distance of the stereo display equipment to the current watching distance. The invention also provides the corresponding tracking type autostereoscopic display control device, the corresponding tracking type autostereoscopic display control system and the display equipment. The watching adaptation distance of the stereo display equipment can be adjusted in a relatively large range by adjusting the controllable light splitter according to a dynamic stereo image synthesis technology, so that the autostereoscopic display equipment has a relatively large watching range.

Description

technical field [0001] The present invention relates to a stereoscopic display technology, and more particularly, to a tracking type naked-eye stereoscopic display control method and device, as well as a corresponding stereoscopic display device and a stereoscopic display system. Background technique [0002] The current stereoscopic image display methods can be roughly divided into three categories, namely, glasses type, head-mounted display (Head Mount Display) type, and naked-eye type which will be introduced in this article. Glasses-free type includes many types, usually realized by lens array technology, parallax barrier technology, etc. The naked-eye stereoscopic display device is mainly assembled from a two-dimensional (2D) flat panel display (including liquid crystal display, plasma display, field emission display, and organic electroluminescence display, etc.) and light-splitting devices such as gratings. The gratings used can be divided into slit gratings and cyli...
