采用上述步骤S10-S70的处理流程,可有效去除图像白点干扰,滤除图像噪声,结合视距和瞳距调节过程,可使得佩戴者观看到的图像更加清晰。

具体地,在获取用户输入的瞳距调节信号时,显示瞳距调节界面。上述瞳距调节界面包括从左至右延伸的横线条和从上至下延伸的竖线条,横线条的两端设置有垂直于横线条的短纵线条,竖线条的两端设置有垂直于竖线条的短横线条,如图2d所示。

在头戴显示器系统上电启动,显示开机界面,预定时间之后自动进入左眼视度调节界面,用户根据提示旋转左眼视度调节旋钮进行视度调节,如调整清晰,单击模式按键退出并进入右眼视度调节界面,用户根据提示旋转右眼视度调节旋钮进行视度调节,如调整清晰,单击模式按键退出并进入瞳距调节界面,用户根据提示滑动瞳距调节滑钮调节瞳距,如画面无重影,单击模式按键退出并进入视频播放主界面,如视频播放主界面显示不清晰,可单击模式按键重新进行视度和/或瞳距调节步骤。
进一步地,上述双目3D视频显示方法中,产生与视频数据的分辨率对应的标准时序信号的步骤具体包括:分别产生行同步信号、场同步信号和数据使能信号DE,通过该三个信号保证后续处理流程同步。
如图3所示,上述双目3D视频显示方法中步骤S40具体包括:
S41、在所述数据使能信号DE有效时,依次读取当前3D视频数据帧第m行、第m+1行和第m+2行像素点的数据,并分别存入三个缓存单元:第一缓存单元、第二缓存单元和第三缓存单元;
S42、对当前像素点的数据进行非线性平滑处理;其中,m为自然数。

步骤S421、读取以当前像素点为中心点的原始3x3矩阵像素点对应的数据,对3x3矩阵中的每行像素点的数据按由大到小顺序进行排序,形成新的3x3矩阵;即,参阅图5,对于由P11、P12……P32、P33构成的3X3像素点矩阵,对第一行三个像素点数据进行排序为:Pmax1、Pmed1、Pmin1;对第二行三个像素点数据进行排序为:Pmax2、Pmed2、Pmin2;对第三行三个像素点数据进行排序为:Pmax3、Pmed3、Pmin3,得到新的3x3矩阵;
