Embodiment 1
[0022] figure 1 As shown, a naked-eye 3D display mobile phone case, the body part corresponding to the screen is a 3D grating panel with tempered glass as the base material, the edge of the mobile phone case is a cavity made of TPU material, and the 3D grating panel is covered on the mobile phone screen, and the 3D grating is parallel Arranged lenticular lenses, the lenticular lenses are arranged at a certain angle with the pixels of the mobile phone screen, and the simple 3D calibration device is used for automatic 3D calibration, and the 3D display unit displays 3D images according to the calibrated 3D display parameters.
[0023] Specifically in this implementation example, the 3D effect needs to be calibrated because of errors. The main sources are the production process error of the mobile phone case itself, the assembly error of the mobile phone screen and camera, the error caused by the thermal expansion and contraction of the temperature, aging, and drop. System errors...

The invention relates to the field of 3D display technology, and in particular, to a 3D display device and a 3D calibration device and a 3D calibration method. The 3D display device comprises a frontcamera, 2D display panel, an external fixing device, a 3D raster panel, a 3D display unit and a 3D calibration unit. The 3D calibration device is also a kind of packaging box, the packaging box is a heaven and earth cover type, a supporting device is attached to the interior of the box body for supporting and fixing the box cover at a certain height, an optical reflection lens is arranged on the inner surface of the box cover, the display screen of the 3D display device is flatly placed in the box body, the camera is aligned to the lens in the box cover, the 3D display unit displays a featurepattern sequence through the screen, and shoots a mirror sequence of the feature patterns, and the 3D calibration unit processes the image sequence and obtains preferred 3D display parameters. The invention provides an inexpensive 3D display scheme and an automatic calibration scheme, which is beneficial to the promotion of 3D products.
Description
technical field [0001] The present invention relates to the technical field of 3D display, in particular to a 3D display device and a 3D calibration device and method. Background technique [0002] In recent years, with the continuous maturity of 3D technology, the 3D display industry has developed rapidly, various 3D display products have been introduced to the market, and naked-eye 3D display technology has emerged as the times require. Glasses-free 3D display technology allows the left and right eyes to see two different pictures with parallax on the display screen without using any tools, and when they are reflected to the brain, people will have a three-dimensional sense. It also uses The principle of parallax of the human eye is realized, and different images are sent to the left and right eyes of the viewer, so as to achieve a three-dimensional visual effect. Since the observer of naked-eye 3D display can experience 3D display without wearing glasses, it is more in li...
