Description

Glasses-free 3D image display

technical field

The present application relates to the field of display, in particular to the field of stereoscopic display, especially to a naked-eye three-dimensional image display.

Background technique

Integrated Imaging Display (Integral Imaging Display, IID) is a naked-eye three-dimensional display technology. An integrated imaging display usually consists of a lens array, a flat panel display (FPD), a control unit and a computing unit. The FPD is usually a liquid crystal display (Liquid Crystal Display, LCD). By displaying images on a flat panel display, a three-dimensional image is created in the viewing space. The image displayed on the FDP is called Elemental Image Array (Elemental Image Array, EIA), which consists of many elemental images (Elemental Image, EI), and each unit image corresponds to a lens. The unit image array is formed by the computer according to the light calculation model (Computational Ray Model) of the integrated imaging display, by graphically drawing a three-dimensional model or rearranging and combining image pixels captured at multiple perspectives. The observer observes the EIA displayed on the FDP through the lens array, and can see the three-dimensional image without wearing any glasses.

According to the working principle of the integrated imaging display, in order to realize the high-resolution three-dimensional image and the integrated imaging display with a large viewing angle, it is necessary to use a high pixel density FPD. The pixel density of the FPD can be measured by the number of pixels per inch (Pixels per inch, PPI). As the PPI of the FPD increases, the allowable viewing angle of the integrated imaging display increases accordingly, making the IID technology closer to practical requirements.

With the development of electronic technology, high-PPI FPD technology is becoming more and more mature. High-PPI FPD technology was first applied to display screens of portable mobile devices such as mobile phone screens. However, in several practical applications, it is necessary to implement a display screen with a certain size, for example: a mobile device with a large screen, a monitor screen of a personal computer, a large-screen TV, a public display, and the like. When the size of the panel becomes larger, in order to maintain a low level of dead pixel rate on the entire panel, FPD with high PPI is very difficult to manufacture, resulting in high cost or difficult to realize. In terms of technology, in order to avoid these difficulties, another solution to realize large-size and high-PPI FPDs is to use a splicing method to splice multiple smaller high-PPI FPDs side by side to form a large-size, high-resolution flat panel display. In order to ensure the visual quality of the image, it is hoped that the stitching seam should be as narrow as possible. Especially for 3D displays, the black borders formed by splicing gaps seriously affect the 3D visual effect, and it is hoped that they can be eliminated.

Various exemplary embodiments of the present application have been described above, and the naked-eye three-dimensional image display provided by the present application uses a special optical structure to make the splicing seams invisible, thereby realizing seamless splicing. Using the naked-eye three-dimensional image display provided by the embodiment of the present application, a large-area integrated imaging display can be realized through seamless splicing under the limitation of the existing limited display technology and optical hardware processing precision.

In order to further improve the image quality, the introduced image deformation is corrected and compensated. In some embodiments, the image may be corrected in software.

This computational model describes the position and pose of light rays in three-dimensional space for each pixel displayed on the flat panel display.

Next, in step 1102, a three-dimensional image is generated using the imaging computational model of the system.

When calculating a three-dimensional image, for each pixel on the flat panel display, intersect its corresponding light with the three-dimensional object model, assign the color value at the intersection to the pixel, and then obtain the three-dimensional image corresponding to the three-dimensional object. Since the system imaging calculation model obtained through calibration describes the actual light propagation with high precision, using this model, the regenerated image imaging geometric relationship conforms to the real lens array imaging model, so that the correct three-dimensional image can be displayed.

Some embodiments of the present application provide a method for correcting a three-dimensional image. First, a calculation model of system imaging is obtained through calibration, and then the calculation model is used to generate a three-dimensional image. This provides an efficient software approach to compensate for image distortion due to the introduction of special optical structures, providing a cost-effective solution for realizing large-screen 3D integral imaging displays.
