Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] figure 1 101 in is to design the naked-eye three-dimensional calibration software according to the naked-eye three-dimensional display characteristics. In naked-eye 3D display, in order to obtain the correct naked-eye 3D display effect, the RGB values of the sampled M viewpoint images must be calculated according to the actual line number LPI value of the lenticular lens grating, the actual tilt angle α, and the dot pitch DOT of the display screen of the mobile phone device. The components are filled into the RGB components of the stereoscopic image to obtain a stereoscopic image that can be displayed correctly. For different mobile devices and different lenticular devices, the naked-eye 3D calibration software only needs to adjust the actual line number LPI value of the lenticular grating, the actual tilt angle α value and ...

Abstract

The invention relates to the technical field of naked eye 3D display, and discloses a mobile phone grating film calibration method based on naked eye 3D. Parameters of a grating film of a mobile phoneare calibrated through naked eye three-dimensional calibration software. The parameters are recorded and transmitted to the naked eye three-dimensional display software at the same time, and the naked eye three-dimensional display software corrects the presented content through the parameters so as to achieve the correct naked eye three-dimensional display effect. The method can adapt to lenticular gratings of any model and mobile phone equipment, naked eye three-dimensional display content can be calibrated rapidly and efficiently to achieve a correct naked eye display effect, and meanwhilethe problem that the display effect is wrong due to mobile phone film pasting deviation is solved. The development of a lenticular grating type naked eye three-dimensional mobile phone display technology is greatly promoted.

Description

technical field [0001] The invention relates to the technical field of naked-eye 3D display, in particular to a method for calibrating a grating film of a mobile phone based on naked-eye 3D. Background technique [0002] With the rapid development of mobile terminals, ordinary two-dimensional display technology can no longer satisfy people's pursuit of display effects. Compared with two-dimensional display technology, naked-eye three-dimensional display technology uses advanced optical technologies such as beam lenses and special algorithms to customize video clips. The source can allow the audience to obtain an unprecedented "high-fidelity" visual experience. It has the advantages of lifelike images, strong immersion, simultaneous observation by multiple people and real-time interaction, etc., and quickly occupied the display market. At present, the mainstream naked-eye 3D mobile phone is implemented in the form of an ordinary mobile phone and a mobile phone case with a gra...
