基于柱镜光栅LCD自由立体显示设备的通用立体图像分解方法
摘要：
本发明公开了一种基于柱镜光栅LCD自由立体显示设备的通用立体图像分解方法。包括以下步骤：1)测量柱镜光栅的实际线数LPI值和实际倾斜角α值；2)根据实际线数LPI值和实际倾斜角α值以及立体图像的视点个数N和分辨率，将立体图像的RGB分量填充到N个视点图像的RGB分量中，得到N个粗略视点图像，其中，N≥2；3)对N个粗略视点图像中的部分RGB分量进行修正，得到最终的N个视点图像。本发明能够从具有特定视点个数、特定分辨率和特定光栅参数的立体图像中分解出具有不同视觉角度的N个视点图像，然后再利用通用的立体图像合成方法将其合成为所需分辨率、视点个数和光栅参数的立体图像，从而大大扩展了立体图像的应用领域。

The invention discloses a universal three-dimensional picture dissection method based on lenticular grating LCD (liquid crystal display) free three-dimensional display device, comprising the followingsteps: 1) measuring the actual lines LPI value and actual elevation angle Alpha value of the lenticular grating; 2) filling the RGB (red, green, blue) components of N sampled viewport pictures in theRGB components of the three-dimensional pictures according to the actual lines LPI value, the actual elevation angle Alpha value and the viewport number N and resolution factor of the three-dimensional picture so as to obtain N rough viewport pictures, wherein, N is more than or equal to 2; 3) amending partial RGB components of N rough viewport pictures so as to obtain N final viewport pictures.The universal three-dimensional picture dissection method can dissect N viewport pictures with different visual angles from three-dimensional pictures with specific viewport numbers, specific resolution factors and specific grating parameters, and then utilizes a general three-dimensional picture synthesis method to synthesize into three-dimensional pictures with required resolution factors, viewport numbers and grating parameters, thereby greatly expanding the application fields of three-dimensional pictures.
