Video display device for detecting stereoscopic image information

Abstract

This invention, as a video display device for detecting stereoscopic image information, includes a cover plate, a capacitive touch panel, and a glasses-free 3D display panel stacked sequentially from the outside in. A laser camera module is disposed on an inner surface of the cover plate. The laser camera module faces the outer surface of the cover plate to capture images to generate an original image of the captured object or surrounding environment, and a grayscale depth map corresponding to the original image. The original image and the grayscale depth information can be provided to a remote device to generate stereoscopic image information. At the local end, a stereoscopic image of the remote end can also be generated based on the received original image and the corresponding grayscale depth map, and the stereoscopic image can be imaged through the glasses-free 3D display panel.

Claims

1. A video display device for detecting stereoscopic image information, comprising: a naked-eye 3D display panel, which is a parallax-type stereoscopic display panel having a display surface that can be viewed by a user with the naked eye; a capacitive touch panel attached to the display surface of the naked-eye 3D display panel, the capacitive touch panel having an operation surface; a cover plate having an inner surface and an outer surface facing each other, the cover plate being attached to the operation surface of the capacitive touch panel with the inner surface, an opaque ink area being formed around the inner surface, the area surrounded by the ink area being a transparent and visible viewing area; a LiDAR camera module disposed on the ink area of ​​the cover plate, the LiDAR camera module facing the outer surface of the cover plate to take pictures to generate a two-dimensional original color image and a grayscale depth map corresponding to the original color image.
