实施该发明的最佳实施例
本发明的最佳实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解,现对照附图详细说明本发明的具体实施方式。
发明实施例
实施例
参考图1,本实施例的裸眼3D显示屏排图自动校准方法应用于具有显示屏的电子设备,电子设备在显示屏侧具有摄像头,该显示屏上覆盖有3D膜。作为选择,3D膜可选用柱状透镜式3D膜,也可以选用视障式3D膜,以及其它具有裸眼显示作用的3D膜。在自动校准前,首先在显示屏上覆盖3D膜,然后将平面镜放置在显示屏侧,平面镜的镜面(正面)与显示屏相对设置,且保证平面镜和显示屏平行,需要注意的是:平面镜和显示屏并非保持绝对平行,这对于用户来说比较难操作,本实施例要求平面镜和显示屏的平行误差在预设误差范围内即可。平面镜可使用支架进行支撑,支架的种类和形状在此不做限定,支架能够支撑平面镜并保证平面镜和显示屏平行即可。另外本实施例中平面镜与显示屏之间的距离为预设观看距离的一半,因为根据平面镜成像原理,摄像头(摄像头与显示屏在同一平面上)与平面镜的镜面图像之间的距离为摄像头与平面镜之间距离的两倍。设置完成后即可开始自动校准,该方法包括下述步骤:
S1、显示屏按照预设观看距离显示第一3D测试图,通过摄像头获取第一3D测试图在平镜面中的镜面图像,其中第一3D测试图包括第一单色3D左图和黑色3D右图,由第一单色3D左图和黑色3D右图可构成3D图。第一单色3D左图和黑色3D右图即为纯色3D图,例如第一单色3D左图为绿色纯色图,即RGB(0,255,0),黑色3D右图为黑色纯色图。
S2、按照预设算法调整显示屏的3D显示旋转角度和左右偏移量,通过摄像头获取每次调整后的镜面图像,并获取每次镜面图像中的最大像素块的有效像素点数。
具体的,获取每次调整后的镜面图像后,查找镜面图像中颜色接近的连续像素块,并获取每次镜面图像中的最大像素块的有效像素点数。步骤S2中按照预设算法调整显示屏的3D显示旋转角度和左右偏移量包括:3D显示旋转角度保持不变,调整左右偏移量;以及左右偏移量保持不变,调整3D显示旋转角度。以下分别进行说明。
首先,3D显示旋转角度保持不变,调整左右偏移量包括:3D显示旋转角度保持不变,从初始偏移量起按照预设步长逐步增加或逐步减小左右偏移量,预设步长可根据调节精度进行设置,例如调节过程使用百分比作为度量,每次预设 步长为0.1。进一步,从初始偏移量起按照预设步长逐步增加或逐步减小左右偏移量包括:在每次调整左右偏移量后,若镜面图像中的最大像素块的有效像素点数在持续增加,即调整后的有效像素点数大于调整前的有效像素点数,则说明调整的方向是正确的,可继续进行调整直至出现有效像素最大值。当然,在调整过程中还可能出现另一种情况,即在每次调整左右偏移量后,若镜面图像中的最大像素块的有效像素点数在调整后减小,说明调整方向是不正确的,则从初始偏移量起反向按照预设步长逐步调整左右偏移量,此处的反向是指若原来是增加的,则调整为减小;若原来是减小的,则调整为增加。
其次,左右偏移量保持不变,调整3D显示旋转角度包括:左右偏移量保持不变,从初始旋转角度起按照预设步长逐步增加或逐步减小3D显示旋转角度,预设步长可根据调节精度进行设置,例如0.1度。进一步,从初始旋转角度起按照预设步长逐步增加或逐步减小3D显示旋转角度包括:在每次调整3D显示旋转角度后,若镜面图像中的最大像素块的有效像素点数在持续增加,即调整后的有效像素点数大于调整前的有效像素点数,则说明调整的方向是正确的,可继续进行调整直至出现有效像素最大值。当然,在调整过程中还可能出现另一种情况,即在每次调整3D显示旋转角度后,若镜面图像中的最大像素块的有效像素点数在调整后减小,说明调整方向是不正确的,则从初始旋转角度起反向按照预设步长逐步调整3D显示旋转角度,此处的反向是指若原来是增加的,则调整为减小;若原来是减小的,则调整为增加。
进一步,上述两个参数可进行间隔轮训式调整,即每调节一个3D显示旋转角度,对左右偏移量进行一轮调节,获取本轮调节中每次镜面图像中的最大像素块的有效像素点数。然后调整3D显示旋转角度,再对左右偏移量进行一轮调节,获取本轮调节中每次镜面图像中的最大像素块的有效像素点数。按照该规律找到可调参数范围内的镜面图像中的最大像素块的有效像素点数。
S3、将筛选出的最大有效像素点数所属镜面图像对应的3D显示旋转角度和左右偏移量作为校准参数。
本实施例通过摄像头获取镜面内的显示效果图像,并根据镜面图像自动完成校准,不需要用户再一点点的手动进行调节,大大提高用户体验,且本实施例的 调整效果更优。
实施例
参考图2,在上述实施例的基础上,本实施例的裸眼3D显示屏排图自动校准方法,在步骤S1之后步骤S2之前,方法还包括:
S121、获取镜面图像中同色素的连续像素块,查找镜面图像中颜色接近的连续像素块,连续像素块会形成斜条纹。
S122、判断连续像素块形成的斜条纹数量是否大于预设条纹数量。
S123、若连续像素块形成的斜条纹数量不大于预设条纹数量,则将当前3D显示旋转角度作为初始旋转角度。说明此时的3D显示旋转角度接近最佳旋转角度,可直接执行步骤S2。
进一步,在步骤S122之后方法还包括:
S1241、若连续像素块形成的斜条纹数量大于预设条纹数量,则获取斜条纹之间的水平宽度。在获取斜条纹之间的水平宽度时,要选取连续斜条纹中间的条纹,计算两条相邻斜条纹之间的宽度;为提高精度,可计算多个相邻斜条纹之间的宽度,然后求平均值。例如连续斜条纹一共有5条,则计算2-3条纹、3-4条纹之间的宽度,然后计算平均值。
S1242、根据斜条纹之间的水平宽度计算出显示屏上斜条纹的实际宽度。
S1243、根据显示屏上斜条纹的实际宽度和当前排图截距计算出最佳排图截距。
S1244、根据最佳排图截距和物理光栅宽度计算出当前3D显示旋转角度,将当前3D显示旋转角度作为初始旋转角度。
本实施例中考虑到用户在粘贴3D膜后与最佳3D显示旋转角度的差别较大问题,通过条纹数量判断是否需要计算最佳排图截距,进一步提高了自动调节的精度,同时也可提高调节效率。
实施例
参考图3,上述实施例中,平面镜与手机屏之间的距离为预设距离,
在上述实施例的基础上,本实施例的裸眼3D显示屏排图自动校准方法,在步骤S1之前方法还包括:
S01、显示屏显示第二3D测试图,通过摄像头获取第二3D测试图在平镜面中的镜面图像,第二3D测试图包括第三单色3D左图和第三单色3D右图,由第三单色3D左图和第三单色3D右图可构成3D立体图。例如第三单色3D左图和第三单色3D右图分别为绿色单色3D左图和绿色单色3D右图,即RGB(0,255,0)。
S02、根据第二3D测试图的镜面图像确定显示屏在第二3D测试图中的位置和大小。获取镜面图像后,查找颜色接近的连续像素块,如果第三单色3D左图和第三单色3D右图为绿色单色3D左图和绿色单色3D右图,则查找绿色接近的连续像素块。找到连续像素块中形状与显示屏形状最接近的连续像素块,其中显示屏形状长宽比已知,则该像素块即为第二3D测试图在平镜面中的镜面图像。
S03、根据显示屏在第二3D测试图中的位置和大小,以及显示屏的实际长度PL和摄像头的视场角fov计算显示屏到镜面图像的距离L:
L=(PL*(W/pw)/2.0)/tan(fov/2.0)
其中,W为摄像头的最大像素宽度,pw为显示屏在镜面图像中的长度,tan为三角函数。
相较于上述实施例,本实施例不再需要用户将平面镜摆放在预设距离,而是可任意距离摆放,摄像头可通过测试图像获取显示屏到镜面图像的距离,从而更加简化校准操作,用户在放置平面镜时只需保证平面镜与显示屏平行即可。
