【摘要】：立体显示技术突破了传统显示技术的限制,在显示中加入了深度信息。立体显示技术能带给观众逼真的视觉体验,因而成为了新一代显示技术的研究热点。自由立体显示技术能够让观众在不佩戴辅助设备的情况下从多角度观看立体画面,清晰度高,深度感好,受到了观众的好评。同时,其成本低廉,因此在市场上有着良好的发展前景。本文在实验室现有的立体显示系统平台上,重点研究了基于平板显示器的光栅式自由立体显示合成算法,取得的创新性成果包括： 1)在原有的基于黑白图像测量光栅参数方法的基础上,提出了用迭代法测量光栅参数的改进方法,提高了测量的精度。参数精度的提高,有助于提高立体图像的质量,优化显示效果。 2)在原有的立体图像合成方案基础上,通过理论推导,提出了一种处理分数子视点的方法,从而优化了合成图像的效果。结合现有的超多视点合成方案及实验室的工程基础,实现了完整的2路转8路,8路转28的超多视点合成方案,具有良好的显示效果。 3)针对立体显示中出现的串扰现象,本文在总结现有的降低图像串扰方案的基础上,说明了矩阵滤波方案的优点,并优化了当前的矩阵滤波方案。改进后的方案既克服了传统方案调节粗糙的缺点,同时也避免了现有方案在调整后的图像色彩上与原始图像出现较大偏差的缺点,实验证明该方案有助于提高图像质量。
[Abstract]:Stereoscopic display technology breaks through the limitation of traditional display technology and adds depth information to display. Stereoscopic display technology can bring realistic visual experience to the audience, so it has become the research hotspot of the new generation of display technology. Auto-stereoscopic display technology enables viewers to view stereoscopic images from multiple angles without wearing auxiliary devices, with high clarity and good depth, which is well received by the audience. At the same time, its cost is low, therefore has a good development prospect in the market. In this paper, the grating free stereoscopic display synthesis algorithm based on flat panel display is studied on the platform of the existing stereoscopic display system in laboratory. The innovative results are as follows: 1) based on the original method of measuring grating parameters based on black and white images, an improved method of measuring grating parameters by iterative method is proposed, which improves the precision of measurement. The improvement of parameter precision is helpful to improve the quality of stereo image and optimize the display effect. 2) on the basis of the original stereo image synthesis scheme, a method to deal with the fractional sub-viewpoint is proposed through theoretical derivation, thus the effect of the synthesized image is optimized. Combined with the existing super-multi-view synthesis scheme and the engineering foundation of the laboratory, a complete super-multi-view synthesis scheme with two paths to eight paths and eight paths to 28 is realized, which has a good display effect. 3) aiming at the crosstalk phenomenon in stereoscopic display, this paper summarizes the existing image crosstalk reduction schemes, explains the advantages of the matrix filtering scheme, and optimizes the current matrix filtering scheme. The improved scheme not only overcomes the shortcomings of the traditional scheme to adjust the roughness, but also avoids the shortcoming that the existing scheme has a big deviation from the original image in color adjustment. The experiment shows that the scheme is helpful to improve the image quality.
