Description
技术领域 technical field
本实用新型涉及一种裸眼立体显示器视觉特性测量器。The utility model relates to a visual characteristic measuring device for a naked-eye three-dimensional display.
背景技术 Background technique
立体显示器需要一对等同于双眼实际观看的图像，即通常所说的“立体对”；同时需要把立体对图像正确无误地送到人的眼睛，对裸眼立体显示器而言，是用光学空分法完成视图的分离，每个视图的光线被特制的光学元件分开后在显示器前方的空间里传播，锲形的光束使视图产生会聚作用，形成了分别对应于左右眼亚屏幕的独立视区，独立视区在空间上是呈菱柱状的，立体显示的效果取决于左右眼视图的正确接收，对裸眼立体显示器而言，如果不存在纯净的左、右眼独立视区，或独立视区间的图像存在严重的相互串扰，眼睛将接收不到对应的立体对图像，人脑就无法进行立体融合了。A stereoscopic display requires a pair of images that are equivalent to those actually viewed by both eyes, which is commonly referred to as a "stereo pair". The separation of views is accomplished by using a special optical element. The light of each view is separated by a special optical element and propagates in the space in front of the display. The wedge-shaped beams make the views converge, forming independent viewing areas corresponding to the left and right eye sub-screens. The independent viewing area is rhombic in space, and the effect of stereoscopic display depends on the correct reception of left and right eye views. For naked-eye stereoscopic display, if there is no pure left and right eye independent viewing area, or There is serious crosstalk between the images, and the eyes will not be able to receive the corresponding stereo pair images, and the human brain will not be able to perform stereo fusion.
评价使用测量的方法，根据仪器测试的客观数据与标准参数量值进行比对，从而判断立体显示效果的优劣。定量测量的方法是研究领域和计检部门实施评定的重要依据。The evaluation uses the measurement method, and compares the objective data of the instrument test with the standard parameter values to judge the quality of the stereoscopic display effect. The method of quantitative measurement is an important basis for the evaluation of the research field and the measurement and inspection department.

The measured pitch is selected as 1 degree (or 1 mm), which can also be easily transformed into plane coordinates. According to the image data processing method, the brightness of the own image and the other image of different viewing angles can be obtained, and the corresponding stereoscopic degree can be calculated.
