Image generation method, test method and system of lenticular grating naked eye 3D display screen

Abstract

The invention discloses a 3D image generation method, test method and system for a lenticular grating naked-eye 3D display screen, the resolution of a 3D image is the same as that of each preset viewpoint image, and the method comprises the following steps: for each row of sub-pixels in the 3D image, determining whether sub-pixel migration exists in the sampling process of the 3D image of the row, and if yes, determining whether the sub-pixel migration exists in the sampling process of the 3D image of the row; determining a target sequence of each viewpoint image; and determining the value of each sub-pixel in the 3D image in a sub-pixel manner one by one according to each viewpoint image and the target sequence thereof. The 3D image generated by the method has the same resolution as each viewpoint image, the calculation process is simple, the optical parameters of the lenticular grating display screen are fully considered, and the 3D image required by the test can be effectively generated. Furthermore, through the test system of the lenticular grating naked-eye 3D display screen, a required 3D test image is generated based on the image generation method, so that the standardized test of multiple optical properties of the lenticular grating naked-eye 3D display screen is realized. 本申请公开了一种柱镜光栅裸眼3D显示屏的3D图像生成方法、测试方法及系统，所述3D图像与预设的各视点图像的分辨率相同，所述方法包括：对于3D图像中的每一行子像素：确定在所述行的3D图像的采样过程是否存在子像素迁移，并据此确定各视点图像的目标顺序；根据各视点图像及其目标顺序，逐个子像素地确定3D图像中各个子像素的值。用所述方法生成的3D图像与各视点图像具有相同的分辨率，计算过程简单，且充分考虑了柱镜光栅显示屏的光学参数，能够有效生成测试所需的3D图像。进一步地，通过柱镜光栅裸眼3D显示屏的测试系统，基于所述图像生成方法生成所需的3D测试图像，以实现柱镜光栅裸眼3D显示屏多项光学性能的标准化测试。
