Problems solved by technology

Wearing linear polarized glasses to watch 3D images greatly restricts the doctor's habit of adjusting the head angle, which brings inconvenience to doctors during surgery.
In addition, in the stereoscopic display devices of the prior art, there is a technology that uses a single-point infrared light as a tracking mark, but the data tracked by the single-point infrared light will be different from the actual situation when the doctor turns his head and tilts his head to watch, which will affect the viewing effect.

Embodiment approach 1

[0028] See figure 1 , figure 1 It is a schematic diagram of the structure of the stereoscopic display device of the present invention. Such as figure 1 As shown, the stereoscopic display device of the present invention includes a tracking device 30, a spectroscopic unit 50, and a display unit 40. The tracking device 30 is used to obtain position information of a target object, and the spectroscopic unit 50 is located on the display side of the display unit 40, The image displayed by the display unit 40 is spatially divided into a left view and a right view. The stereoscopic display device also includes an image playback processing unit 20, respectively connected to the tracking device 30 and the display unit 40. The image playback processing unit 20 is based on the position information of the target object, the grating parameters of the spectroscopic unit 50, and the display unit 40. The image to be played is processed in real time with the display parameters of, and then sent ...

Embodiment 1

[0037] In Embodiment 1 of the present invention, in order to obtain a better real-time stereoscopic display effect, it is necessary to perform an optical design on the spectroscopic unit and the display unit according to the grating parameters of the spectroscopic unit and the display parameters of the display unit. The optical design is based on the following formula:

[0038]

[0039]

[0040] (3) m*t=p-pitch

[0041] In the above formula, F is the distance between the light splitting unit and the display unit (that is, the distance between the grating in the above-mentioned grating parameter and the display panel), L is the distance between the viewer and the display unit,

[0042] IPD is the matching interpupillary distance, the distance between ordinary people’s pupils, for example, the general value is 62.5mm, l-pitch is the pitch of the light splitting unit, and p-pitch is the pixel arrangement on the display unit Pitch, n is the number of stereo views, m is the number of pixe...

Embodiment 2

[0049] See Figure 4 , Figure 4 It shows a schematic structural diagram of a preferred embodiment of the tracking device in the stereoscopic display device of the first embodiment of the present invention. Such as Figure 4 As shown, Embodiment 2 of the present invention also proposes another tracking device 30, which includes:

[0050] The marker point setting unit 1 is used to set more than three marker points corresponding to the spatial position of the target object; the marker points here can be set on the target object, or not on the target object, but set relative to the target object The position relationship is also available on objects that move synchronously with the target object. For example, if the target object is the human eye, you can set mark points around the orbit of the human eye; or arrange glasses around the human eye and set the mark point on the frame of the glasses, or set the mark point in the position relationship with the human eye On the ears of re...

Abstract

The invention provides a stereoscopic display device and method, and belongs to the technical field of stereoscopic display. The method comprises a tracking step in which position information of a target object is tracked, and a display step in which a stereoscopic image is displayed according to the position information. The tracking step further comprises the following steps that S11) more than three marking points are arranged in corresponding to the spatial position of the target object; S12) position information of the marking points is obtained; and S13) according to the inclination angle of the target object relative to the horizontal surface, the position information of the marking points is corrected. The stereoscopic display device and method have the advantages the tracking position is more accurate and a display effect is better compared with tracking by human eyes.

Description

Technical field [0001] The present invention relates to the field of stereo display technology, in particular to a stereo display device and a stereo display method. Background technique [0002] In recent years, the three-dimensional display technology has developed rapidly and has become a research focus. Stereoscopic display technology has become more and more widely used in various fields such as medical care, advertising, military, exhibitions, games and vehicle displays. Stereoscopic display technology includes glasses-wearing stereoscopic display technology and glasses-free stereoscopic display technology. Among them, the glasses-wearing stereoscopic display technology developed very early, and the technology is relatively mature and is still used in many fields; while the naked-eye stereoscopic display technology started late, and its technical difficulty is higher than that of the glasses-type. There are applications in related fields, but the display effect cannot mee...
