A method for stereoscopic image

Abstract

In order to solve the problem that a 2D display screen does not have a parallax image and a light-splitting element, and it is difficult to realize a stereoscopic display, the present invention proposes a method for stereoscopic image. The method for stereoscopic image includes setting a 2D display screen, a first aperture, a second aperture, a face tracking component and an image processing algorithm. The first aperture and the second aperture are placed in front of the 2D display screen and are placed on the left and right sides of the 2D display screen respectively. The image processing algorithm calculates multiple polygonal areas according to the position of the face, and these polygonal areas are fused with the aperture as a background image to construct a three-dimensional space. At the same time, an object image is added to the background image, thereby producing a visual effect that the object is located in a three-dimensional space.

Description

Technical Field

[0001] The present invention belongs to the field of display technology, and more specifically, relates to a method for stereoscopic image. Background Art

[0002] Traditional grating or integrated imaging stereoscopic display requires the use of a spectroscopic element to split light in order to achieve stereoscopic display. Taking grating 3D display as an example, it uses binocular parallax as the basic principle, and uses cylindrical lenses or slit gratings to project different parallax images to different spatial directions to achieve stereoscopic display; while integrated imaging projects an image element array through a lens array to reproduce a stereoscopic light field to achieve stereoscopic display. For both technologies, it is necessary to prepare multiple parallax images in advance to construct a parallax composite image or an image element array, and cooperate with a spectroscopic element to achieve stereoscopic display. In order to achieve a stereoscopic display effect in combination with existing 2D display devices, such as smart phones, computer monitors and other 2D display devices that do not have a spectroscopic element, the present invention proposes a method for stereoscopic image. This method is combined with aperture technology to perform digital image processing, so that 2D display screens can also produce stereoscopic vision. Summary of the invention

[0003] In order to solve the problem that a 2D display screen is not equipped with parallax images and light splitting elements and is difficult to realize stereoscopic display, the present invention proposes a method for stereoscopicizing an image.

[0004] The image stereoscopic method comprises setting a 2D display screen, a first aperture, a second aperture, a face tracking component and an image processing algorithm.

[0005] The first aperture and the second aperture are placed in front of the 2D display screen and are placed on the left and right sides of the 2D display screen respectively, the first aperture is placed on the left side of the 2D display screen, and the second aperture is placed on the right side of the 2D display screen; the first aperture and the second aperture are coated with colors on one side close to the 2D display screen; the first aperture is coated with the first aperture color; the second aperture is coated with the second aperture color.

[0006] The first aperture light blocking portion intersects with the upper and lower edges of the 2D display screen and has a first intersection point and a second intersection point.

[0007] The second aperture light blocking portion intersects with the upper and lower edges of the 2D display screen, and has a third intersection point and a fourth intersection point.

[0008] The face tracking component is used to detect the position of the face.

[0009] An image processing algorithm for an image stereo method is as follows:

[0010] First, a first depth point and a second depth point are set behind the screen;

[0011] Draw a straight line through the first depth point and the face position, and the straight line intersects the 2D display screen at the first depth intersection point;

[0012] Draw another straight line through the second depth point and the face position, the straight line intersecting the 2D display screen at the second depth intersection point;

[0013] Creating a 2D display screen background image, in which a first polygonal area is formed by connecting the first intersection point, the second intersection point and the first depth intersection point using a line segment in the 2D display screen background image;

[0014] In the 2D display screen background image, a third intersection point, a fourth intersection point, and a second depth intersection point are connected by a line segment to form a second polygonal area;

[0015] In the background image of the 2D display screen, a line segment is used to connect the first depth intersection point and the second depth intersection point, and the first polygonal area and the second polygonal area are divided into a third polygonal area and a fourth polygonal area; a boundary line is set between the third polygonal area and the fourth polygonal area;

[0016] A first area color is set in the first polygonal area, and the first polygonal area color is integrated with the first aperture color; a second area color is set in the second polygonal area, and the second polygonal area color is integrated with the second aperture color.

[0017] Specifically, the color of the first polygonal area is completely consistent with the color of the first aperture; the color of the second polygonal area is completely consistent with the color of the second aperture.

[0018] Optionally, a gradient color is used in the first polygonal area, and its color is different from the first aperture color near the first depth intersection point, but is consistent with the first aperture color near the first intersection point and the second intersection point.

[0019] Optionally, a gradient color is used in the second polygonal area, and its color is different from the second aperture color near the second depth intersection point, but is consistent with the second aperture color near the third intersection point and the fourth intersection point.

[0020] The object image to be displayed is merged with the 2D display screen background image, and the object is placed on the 2D display screen background image to form a three-dimensional image.

[0021] Optionally, more third and fourth depth points are set, and the same processing method is adopted as that of the first and second depth points, so as to form a three-dimensional space with a more complex shape;

[0022] Draw a straight line through the third depth point and the face position, and the straight line intersects the 2D display screen at the third depth intersection point;

[0023] Draw another straight line through the fourth depth point and the face position, the straight line intersecting the 2D display screen at the fourth depth intersection point;

[0024] In the 2D display screen background image, a first polygonal area is formed by connecting the first intersection point, the second intersection point, the first depth intersection point and the third depth intersection point using a line segment;

[0025] In the 2D display screen background image, a third intersection point, a fourth intersection point, a second depth intersection point and a fourth depth intersection point are connected by a line segment to form a second polygonal area;

[0026] A first area color is set in the first polygonal area, and the first polygonal area color is integrated with the first aperture color; a second area color is set in the second polygonal area, and the second polygonal area color is integrated with the second aperture color.

[0027] Optionally, the second aperture is removed and only the first polygonal area is calculated and processed.

[0028] In summary, in the present invention, the first polygonal area can be merged with the first aperture to form the left inner surface of the three-dimensional space, the second polygonal area can be merged with the second aperture to form the right inner surface of the three-dimensional space, the third polygonal area, the fourth polygonal area and their boundary lines can constitute the back surface of the three-dimensional space, thereby forming a visual three-dimensional space in space, and the object can be visually present in the three-dimensional space parallel to the 2D display screen. Therefore, the method can achieve a three-dimensional visual effect without using any light splitting element and parallax image.

[0029] Furthermore, in order to make the object image also have a sense of depth, the 2D display screen can be replaced by a 3D display screen, and the face tracking component can be replaced by an eye tracking component. The exact same method can be used to obtain parallax images corresponding to different eye positions and applied to the 3D display screen. BRIEF DESCRIPTION OF THE DRAWINGS
