Problems solved by technology

When the positioning module is far from the center of the display screen, the error of the positioning data of the three-dimensional spatial position of the user's eyes will be exacerbated, and the crosstalk of the display signal will increase due to inaccurate positioning data, and the effective viewing area will be relatively smaller. This has a negative impact on naked-eye stereoscopic display

Embodiment 1

[0076] Please refer to figure 1 , the naked-eye three-dimensional display method provided by the embodiment of the present invention includes the following steps:

[0077] Step 11, acquiring the first coordinates of the user's face of the current user in the camera coordinate system corresponding to a camera.

[0078] Here, the embodiment of the present invention uses the camera of the positioning module to track and detect the three-dimensional spatial position coordinates of the user's face in the camera coordinate system in real time. Specifically, there are many ways to obtain the first coordinates. For example, a single camera can be used to collect the facial image of the face, and combined with laser ranging or infrared ranging to determine the coordinates of the face; Two cameras collect facial images of people's faces, and use positioning algorithms to determine the coordinates of people's faces in the coordinate system of one of the cameras; for another example, use...

Embodiment 2

[0093] When only a single camera is used to track the face in real time, it is usually necessary to pre-establish and save the coordinate data of a standard face in the camera coordinate system. When tracking the face, based on the actual collected user face image and the standard face coordinate data to determine the actual position of the user's face.

[0094] The above-mentioned standard face is used to simulate the frontal face of the user. For example, the shape and size of the standard face can be determined based on the statistical average data of a large number of sample user faces, such as the interpupillary distance of the eyes is 65mm. Then, assuming that the standard human face faces the camera, the coordinate data (hereinafter referred to as standard coordinates) of the standard human face in the camera coordinate system are collected and saved. Here, the facing camera may be that the center point between the eyes of a standard human face coincides with the origin...

Embodiment 3

[0147] Since the positioning error of the user's face cannot be completely eliminated, in naked-eye stereoscopic display, in addition to reducing the positioning error as much as possible, the image layout algorithm can also be optimized to improve the stereoscopic effect caused by positioning errors. The problem.

Abstract

The invention provides a method, device and electronic equipment for auto-stereoscopic display. The method comprises the following steps: obtaining first coordinates of the face of a current user in a camera coordinate system corresponding to a camera; according to a displacement between an origin of a predetermined display screen coordinate system corresponding to a display screen and an origin of the camera coordinate system, and a first rotation matrix of the camera coordinate system relative to the display screen coordinate system, converting the first coordinates into second coordinates in the display screen coordinate system; and according to the second coordinates, carrying out auto-stereoscopic display drawing processing of a stereoscopic film source to be displayed on the display screen. The method, device and electronic equipment for auto-stereoscopic display provided by the invention has the advantages that positioning errors of the eyes of the user in auto-stereoscopic display can be reduced, so that the auto-stereoscopic display effects are better.

Description

technical field [0001] The invention relates to the technical field of naked-eye stereoscopic display, in particular to a method, device and electronic equipment for naked-eye stereoscopic display. Background technique [0002] In the tracking-type naked-eye stereoscopic display, a positioning module (device) is usually required to locate the current three-dimensional space position of the user's eyes, usually the three-dimensional space position of the center point of the two eyes. Then, according to the spatial position, the naked-eye three-dimensional image layout algorithm is processed and displayed on the display screen, so that the left and right views in the three-dimensional film source are accurately projected into the left and right eyes of the user, achieving the tracking-naked-eye three-dimensional display effect. [0003] Due to various reasons, the location where the positioning module is actually installed is usually not at the center of the display screen, an...
