Three-dimensional image display apparatus, methods and systems

The present disclosure provides a three-dimensional image display apparatus, methods and systems. The three-dimensional image display apparatus 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. The user is able to build a complete virtual image by using four color-depth images captured by only four image-capture devices and a display device, thereby improving the visual effect of the virtual image.
