Abstract

The invention relates to a method for correcting multi-anaglyph color cast, comprising the steps of firstly selecting an image with true color from a plurality of anaglyphs as a standard image, then performing color space conversion from RGB to YUV on the standard anaglyph and the color-cast anaglyphs, obtaining the true color gray values of the to-be-corrected color-cast anaglyphs in the YUV color space according to three color correction coefficients K<Y>, K and K<V> of all pixels of the color-cast anaglyphs in the YUV color space, and finally converting the obtained true color gray values from the YUV to the RGB color space, so as to realize the correction of a plurality of color-cast anaglyphs. The invention is capable of realizing color-case correction of a plurality of anaglyphs before synthesizing a stereo image and improving the effect of a free stereo display. The method is simple and feasible.

Description

1. Technical field [0001] The invention relates to stereo shooting technology and digital image processing technology, especially for color correction of multi-parallax images captured by array cameras. 2. Technical Background [0002] Three-dimensional stereoscopic display has always been the dream of human beings. Among them, the multi-view autostereoscopic display based on binocular parallax is an important three-dimensional stereoscopic display. The reader feels the real three-dimensional effect. Its display content comes from scene images captured from multiple angles, which can be generated by 3D modeling software, or multiple disparity maps captured by camera arrays from different angles. In order to increase the stereoscopic viewing area, the number of cameras that need to be installed is usually relatively large, generally as many as 8, or even more than a dozen. However, camera differences are inevitable, even if they are from the same brand, such as CCD color fi...
