Problems solved by technology

[0003] At present, there are still many problems to be solved urgently in the practical application of virtual reality hardware equipment, including: (1) the film source has no versatility: different stereoscopic display devices can only use the film source of its own special format, and the different film source The impact of versatility on the popularization and application of emerging stereoscopic display devices is particularly obvious. These stereoscopic display devices have very few film sources at the beginning of their launch. To reach a certain number of users, it is necessary to continue to increase a large amount of investment in the software produced by film sources.
(2) The volume and weight of the helmet-mounted display and professional-grade stereoscopic glasses are still too large. Compared with Microsoft's augmented reality holographic glasses Hololens, they are much bulkier and have an impact on viewing comfort and immersion
This algorithm reduces the impact of visual competition to a certain extent, but its color distortion is relatively serious, especially in blue and red areas.

Abstract

The invention provides a visual rivalry improving method of a complementary color three-dimensional image for improving color fidelity. The method comprises the steps of transforming symmetrical left view and right view of a three-dimensional image from an RGB color space to a CIE L*a*b* color space; then calculating the sensing area of a cyan lens in the CIE L*a*b* color space; matching and mapping the right view to the two-dimensional sensing area of the cyan lens, and calculating corresponding a* and b* values of each pixel in the matched and mapped right view; adjusting the brightness of the left view and the right view based on a chromatic value, and separately calculating a corresponding L* value of each pixel in the adjusted left view and right view; inversely transforming the processed left view and right view from the CIE L*a*b* color space to the RGB color space to synthesize a red and cyan complementary color three-dimensional image. The method can improve the color fidelity of the complementary color three-dimensional image on the premise of effectively reducing the visual fatigue in view of the three-dimensional image and obtaining more comfortable three-dimensional visual experience.

Description

technical field [0001] The invention relates to a color-complementary stereoscopic image synthesis technology, in particular to a red-cyan complementary color stereoscopic image synthesis technology for improving the visual competition phenomenon of the complementary-color stereoscopic image and improving color fidelity. Background technique [0002] As virtual reality technology entered the "first year of virtual reality" in 2016, virtual reality applications began to enter the stage of commercial promotion. Correspondingly, the hardware level of stereoscopic display devices continues to improve, and people's demand and enthusiasm for stereoscopic display is unprecedentedly high. Stereoscopic display technology can be divided into two categories: one is free stereoscopic display without wearing any auxiliary tools, that is, naked eye stereoscopic display technology, including stereoscopic display, free stereoscopic display based on liquid crystal display, non-glasses hologr...
