  • Publication number: 20240161381
    Abstract: A computer-executable method for generating a side-by-side three-dimensional (3D) image includes the steps of creating a 3D mesh and estimating depth information of the raw image. The method further includes the steps of updating the left mesh area and the right mesh area of the 3D mesh based on the estimated depth information of the raw image and projecting each of the mesh vertices of the left mesh area onto a coordinate system of the side-by-side 3D image based on a left eye position, and projecting each of the mesh vertices of the right mesh area onto the coordinate system of the side-by-side 3D image based on a right eye position. The method further obtains the side-by-side 3D image by coloring the left mesh area and the right mesh area projected onto the coordinate system of the side-by-side 3D image based on the raw image.

  • Publication number: 20240121373
    Abstract: Disclosed are an image display method and a 3d display system. The method is adapted to the 3d display system including a 3d display device and includes the following steps. A first image and a second image are obtained by splitting an input image according to a 3d image format. Whether the input image is a 3D format image complying with the 3D image format is determined through a stereo matching processing performed on the first image and the second image. An image interweaving process is enabled to be performed on the input image to generate an interweaving image in response to determining that the input image is the 3D format image complying with the 3D image format, and the interweaving image is displayed via the 3D display device.

  • Publication number: 20240046608
    Abstract: A 3D format image detection method and an electronic apparatus using the same are provided. The 3D format image detection method includes the following steps. A first image and a second image are obtained by splitting an input image according to a 3D image format. A 3D matching processing is performed on the first image and the second image to generate a disparity map of the first image and the second image. The matching number of a plurality of first pixels in the first image matched with a plurality of second pixels in the second image is calculated according to the disparity map. Whether the input image is a 3D format image conforming to the 3D image format is determined according to the matching number.

  • Patent number: 11836875
    Abstract: An augmented reality screen system includes an augmented reality device and a host. The augmented reality device is configured to take a physical mark through a camera. The host is configured to receive the physical mark, determine position information and rotation information of the physical mark, and fetch a virtual image from a storage device through a processor of the host. The processor transmits an adjusted virtual image to the augmented reality device according to the position information and the rotation information, and the augmentation device projects the adjusted virtual image to a display of the augmented reality device. The adjusted virtual image becomes a virtual extended screen, and the virtual extended screen and the physical mark are simultaneously displayed on the display of the augmented reality device.

  • Publication number: 20220286658
    Abstract: A stereo image generation method and an electronic apparatus using the same are provided. The stereo image generation method includes the following steps. A two-dimensional (2D) original image corresponding to a first viewing angle is obtained, and a depth map of the 2D original image is estimated. Interpupillary distance information of a user is detected. A pixel shift processing is performed on the 2D original image according to the interpupillary distance information and the depth map to generate a reference image corresponding to a second viewing angle. An image inpainting processing is performed on the reference image to obtain a restored image. The restored image and the 2D original image are merged to generate a stereo image conforming to a stereo image format.
