Embodiment approach 1

[0024] See figure 1 , figure 1 A schematic flowchart of a tracking and positioning method for stereoscopic display according to Embodiment 1 of the present invention is shown. The tracking and positioning method for stereoscopic display according to Embodiment 1 of the present invention is characterized in that the tracking and positioning method for stereoscopic display includes the following steps:

[0025] S1 setting at least a first auxiliary positioning point and a second auxiliary positioning point corresponding to the position of the viewer's eyes;

[0026] S2 acquiring the position information of the first auxiliary positioning point and the position information of the second auxiliary positioning point in real time;

[0027] S3 Obtain the position information of the center point of the eyes of the viewer according to the position information of the first auxiliary positioning point and the position information of the second auxiliary positioning point, wherein the c...

Embodiment 1

[0030] When the first auxiliary positioning point and the second auxiliary positioning point are infrared signal emitting units arranged on the head of the viewer, the step S2 specifically includes:

[0031] S21 Receive in real time the first infrared signal and the second infrared signal sent simultaneously by the first auxiliary positioning point and the second auxiliary positioning point;

[0032] S22 Obtain the spatial coordinate information of the first auxiliary positioning point and the spatial coordinate information of the second auxiliary positioning point according to the first infrared signal and the second infrared signal.

[0033] If the position of the center point of the eyes is used as the input of the mapping algorithm, the coordinates of the calculated tracking position need to be converted into the coordinates of the center of the eyes (nasion point).

[0034] See figure 2 and image 3 , figure 2 A schematic diagram showing the relationship between the ...

Embodiment 2

[0039] When the first auxiliary positioning point and the second auxiliary positioning point are feature points of the viewer's face, the step S2 specifically includes:

[0040] S210 Recognizing the face of the viewer in real time, extracting at least two feature points of the face of the viewer, obtaining the positional relationship between each feature point and the eyes of the viewer, and arbitrarily selecting two feature points as the first auxiliary positioning point and the second auxiliary positioning point;

[0041] S220 respectively locate the feature point serving as the first auxiliary positioning point and the feature point serving as the second auxiliary positioning point, and obtain the spatial coordinate information of the first auxiliary positioning point and the spatial coordinate information of the second auxiliary positioning point. Spatial coordinate information.

[0042] Specifically, the feature points extracted by general face recognition algorithms are...

Abstract

The invention belongs to the technical field of three-dimensional display, and provides a tracking and positioning method and device for three-dimensional display. The tracking and positioning methodcomprises the steps of s1, arranging at least a first auxiliary positioning point and a second auxiliary positioning point at the positions, corresponding to the eyes of a viewer; s2, acquiring the position information of the first auxiliary positioning point and the position information of the second auxiliary positioning point in real time; and s3, acquiring the position information of the center point of the two eyes of the viewer according to the position information of the first auxiliary positioning point and the position information of the second auxiliary positioning point, wherein thecenter point of the two eyes of the viewer is the center symmetry point of the left eye and the right eye of the viewer, and taking the position information of the center point of the two eyes of theviewer as the tracking and positioning information during the viewer viewing the three-dimensional display with both eyes. Through the tracking and positioning method and device, the positioning information can be accurately acquired when a viewer is watching the three-dimensional display image with sidelong glance. The crosstalk phenomenon in the process of watching a three-dimensional display image by a viewer with sidelong glance is effectively improved, and the three-dimensional display effect is optimized.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic display, in particular to a tracking and positioning method and device for stereoscopic display. Background technique [0002] In recent years, stereoscopic display technology has developed rapidly and has become a research hotspot. Stereoscopic display technology has been more and more widely used in various fields such as medical treatment, advertising, military, exhibition, game and vehicle display. Stereoscopic display technology includes glasses-wearing stereoscopic display technology and glasses-free stereoscopic display technology. Among them, the glasses-wearing stereoscopic display technology has been developed very early, and is currently relatively mature, and is still used in many fields; while the naked-eye stereoscopic display technology started relatively late, and its technical difficulty is higher than that of wearing glasses. There are applications in related field...
