Abstract

The present disclosure provides a three-dimensional image display apparatus, which includes a first reflecting plate and a display unit. The first reflecting plate corresponds to a first visual angle, has a first reflecting surface, and is made of a translucent material. The display unit receives a first color-depth image corresponding to the first visual angle, and projects the first color-depth image to the first reflecting surface to form a virtual image. The display unit also has a first side, which is used to display the first color-depth image, and a predetermined angle is formed between the first side and the first reflecting surface.

First claim

What is claimed is:

1. A three-dimensional image display apparatus, comprising:
a first reflecting plate, corresponding to a first visual angle, the first reflecting plate having a first reflecting surface, wherein the first reflecting plate is made of a translucent material, and a predetermined angle is formed between a first side and the first reflecting surface;
a second reflecting plate, corresponding to a second visual angle, having a second reflecting surface, wherein the second reflecting plate is made of the translucent material, the predetermined angle is formed between the first side and the second reflecting surface, and the second visual angle is different from the first visual angle;
a third reflecting plate, corresponding to a third visual angle, having a third reflecting surface, wherein the third reflecting plate is made of the translucent material, wherein the predetermined angle is formed between the first side and the third reflecting surface; and
a display unit, receiving a first color-depth image corresponding to the first visual angle, a second color-depth image corresponding to the second visual angle and a complementary color-depth image corresponding to the third visual angle, and projecting the first color-depth image to the first reflecting surface, projecting the second color-depth image to the second reflecting surface and projecting the complementary color-depth image to the third reflecting surface to form a virtual image, wherein the display unit further has the first side, which is used to display the first color-depth image, the second color-depth image and the complementary color-depth image;
wherein the second depth image is obtained by a second depth image-capture device in the second visual angle, and the second color image is obtained by a second color image-capture device in the second visual angle; and
wherein the complementary color-depth image is obtained by matching facial features of a user image in the first color-depth image and the second color-depth image.

2. The three-dimensional image display apparatus as claimed in claim 1 , wherein the first color-depth image is obtained by a first depth image and a first color image, the first depth image is obtained by a first depth image-capture device in the first visual angle, and the first color image is obtained by a first color image-capture device in the first visual angle.

3. A three-dimensional image display method, comprising:
receiving a first color-depth image corresponding to a first visual angle by a display unit;
obtaining a second color-depth image by a second depth image and a second color image, wherein the second depth image is obtained by a second depth image-capture device in the second visual angle, and the second color image is obtained by a second color image-capture device in the second visual angle;
receiving the second color depth image corresponding to the second visual angle by the display unit;
obtaining a complementary color-depth image by matching facial features of a user image in the first color-depth image and the second color-depth image;
receiving the complementary color-depth image corresponding to a third visual angle by the display unit;
projecting the first color-depth image to a first reflecting surface of a first reflecting plate from the display unit, wherein the display unit has a first side, which is used to display the first color-depth image;
projecting the second color depth image to a second reflecting surface of a second reflecting plate;
projecting the complementary color-depth image to a third reflecting surface of a third reflecting plate; and
forming a virtual image based on the first color-depth image through the first reflecting surface, the second color-depth image through the second reflecting plate and the complementary color-depth image through the third reflecting plate;
wherein the first reflecting plate corresponds to a first visual angle, and is made of a translucent material, and a predetermined angle is formed between the first side of the display unit and the first reflecting surface;
wherein the second reflecting plate corresponds to the second visual angle that is different from the first visual angle, and is made of a translucent material, and the predetermined angle is formed between the first side of the display unit and the second reflecting surface; and
wherein the third reflecting plate corresponds to the third visual angle, and is made of the translucent material, the predetermined angle is formed between the first side and the third reflecting surface.

4. The three-dimensional image display method as claimed in claim 3 , further comprising:
obtaining the first color-depth image by a first depth image and a first color image;
wherein the first depth image is obtained by a first depth image-capture device in the first visual angle, and the first color image is obtained by a first color image-capture device in the first visual angle.

5. A three-dimensional image display system, comprising:
a plurality of depth image-capture devices, obtaining a plurality of depth images in a plurality of visual angles, respectively;
a plurality of color image-capture devices, obtaining a plurality of color images in the plurality of visual angles, respectively;
a processing unit, obtaining a plurality of color-depth images in the visual angles according to the depth images and the color images respectively, and obtaining a least one complementary color depth image by matching facial features of a user image in two of the color-depth images;
a plurality of reflecting plates, corresponding to the visual angles and a plurality of reflecting plates, respectively, wherein the reflecting plates are made of a translucent material; and
a display unit, receiving the color-depth images and the complementary color depth image, and projecting the color-depth images and the complementary color depth image to the corresponding reflecting surfaces form a virtual image, wherein the display unit further has a first side, which is used to display the color-depth images and the complementary color depth image, and a predetermined angle is formed between the first side and the first reflecting surfaces.
