Description

3D眼镜及3D显示系统 技术领域
本发明的实施例涉及一种3D眼镜及3D显示系统。
背景技术
3D显示技术是人的双眼分别接收不同画面,然后观看者的大脑对图像信息进行叠加,得到一个具有立体效果的图像的显示技术。3D显示技术通常包括3D眼镜式和裸眼3D式等。由于裸眼3D技术目前还不是很成熟,因此,为了便于观看到理想的3D图像效果,3D眼镜式3D显示技术得到广泛应用。通过3D眼镜的两个镜片,佩戴者两只眼睛可分别接收不同图像,由佩戴者的大脑将两个图像合并起来最终形成立体的影像。
3D眼镜式的3D显示技术中,需要佩戴者的注视点与3D显示装置的视点匹配,即只有当3D眼镜的佩戴者的注视点和3D显示装置的3D图像的焦点匹配时,才能看到清晰的3D图像。目前的一种3D眼镜式的3D显示技术中,3D显示装置的视点通常为固定的2视点,即3D图像的焦点无法根据人眼的注视点的位置调节,因此,当佩戴者的眼球移动或头部转动时,难以看到清晰地3D图像,这影响了3D图像的观看效果。
发明内容
本发明的至少一实施例提供一种3D眼镜及3D显示系统,可在佩戴者的眼球移动或头部转动时,也可以实现3D图像的观看效果。
本发明的至少一实施例提供一种3D眼镜,包括:图像获取装置,用于获取3D图像;镜片,用于显示所述图像获取装置获取的3D图像;瞳孔检测模块,用于检测佩戴者的瞳孔中心的位置;调节模块,用于根据所述瞳孔中心的位置调节所述镜片显示的3D图像的焦点,使所述焦点与佩戴者的瞳孔中心的位置匹配。
本发明至少一实施例还提供了一种3D显示系统,包括:3D显示装置,用于显示3D图像;3D眼镜,用于从所述3D显示装置获取3D图像,使佩 戴者眼前出现所述3D显示装置显示的3D图像,其中,所述3D眼镜为上述任一技术方案所述的3D眼镜。
附图说明
为了更清楚地说明本发明实施例的技术方案,下面将对实施例的附图作简单地介绍,显而易见地,下面描述中的附图仅仅涉及本发明的一些实施例,而非对本发明的限制。
图1为本发明实施例3D眼镜的结构示意图一;
图2为本发明实施例3D眼镜的结构示意图二;
图3为本发明实施例3D眼镜获取的眼睛图像;
图4为图3中的眼睛图像在二值化处理并取反后的图像。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面结合附图对本发明实施例的3D眼镜及3D显示系统进行详细描述。显然,所描述的实施例是本发明的一部分实施例,而不是全部的实施例。基于所描述的本发明的实施例,本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例,都属于本发明保护的范围。
在本发明实施例的描述中,需要理解的是,术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。
参照图1、图2,图1为本发明实施例一种3D眼镜的具体实施例,本实施例所述的3D眼镜,包括:图像获取装置1、镜片2、瞳孔检测模块3和调节模块4。
图像获取装置1用于获取3D显示装置上显示的3D图像,并将获取的3D图像信号向镜片2发出。
镜片2接收到图像获取装置1发出的3D图像信号后,用于显示图像获 取装置1获取的3D图像。
瞳孔检测模块3用于检测佩戴者的瞳孔中心的位置,并将检测到的佩戴者的瞳孔中心的位置信息发出。
调节模块4用于在接收到瞳孔中心的位置信息后,根据所述瞳孔中心的位置信息调节所述镜片显示的3D图像的焦点,使所述焦点与佩戴者的瞳孔中心的位置匹配。
本发明至少一实施例提供的3D眼镜中,由图像获取装置1获取3D图像,并由镜片2向佩戴者显示所述3D图像,因此该3D眼镜能够通过所述瞳孔检测模块3和调节模块4,根据佩戴者瞳孔中心的位置,调节镜片上的3D图像的焦点。由于瞳孔中心的位置可反映佩戴者的注视点的位置,因此可使3D图像的焦点与佩戴者的注视点匹配,使得当佩戴者的眼球移动时,仍能看到清晰地3D影像,这保证了3D图像的观看效果。
在一个实施例中,瞳孔检测模块1包括:成像单元31、图像处理单元32和计算单元33。
成像单元31用于采集佩戴者的眼睛图像,并将采集到的眼睛图像信息发送给图像处理单元32,如图3所示。图3为采集到的眼睛的图像。
图像处理单元32,在接收到眼睛的图像信息后,用于对眼睛图像进行二值化处理得到眼睛的二值化图像,并对二值化图像取反,使眼睛图像变得简单,减小数据量,凸显瞳孔的轮廓,从而得到瞳孔在眼睛中的位置信息,并将瞳孔在眼睛中的位置信息发送给计算单元33,如图4示。图4为图3中的眼睛图像经二值化处理并取反后的图像,图中的白色部分可表示瞳孔在眼睛中的位置。
计算单元33用于接收瞳孔的位置信息,并根据所述瞳孔在眼睛中的位置信息计算佩戴者的瞳孔中心的位置信息。
为了进一步提高了3D图像的观看效果,本发明另一个实施例的3D眼镜还可以包括光源5,光源5用于对佩戴者眼睛进行照明。这可以使所述眼睛的图像更加清晰,提高所述瞳孔中心的位置信息的准确性,从而使佩戴者的瞳孔中心与3D图像的焦点更加精确的匹配,便于将佩戴者的注视点与镜片2显示的3D图像的焦点精确匹配。由此,这提高了3D图像的观看效果。
例如,光源5可以有两个,这两个光源5可以与佩戴者的眼睛一一对应, 其中一个光源5对佩戴者的左眼进行照明,另一个光源5对佩戴者的右眼进行照明。这样可分别对佩戴者的左眼和右眼进行照明,提高了对佩戴者的眼睛的照明效果,有利于使佩戴者双眼的图像均更加清晰,进一步提高所述瞳孔中心的位置信息的准确性,从而提高3D图像的观看效果。
在本发明的至少一个实施例中,为了便于屈光不正(近视、远视、散光等)的用户使用所述3D眼镜,成像单元31还可以用于获取光源5发出的光线从佩戴者眼睛反射出时在瞳孔区的光影动态;图像处理单元32还可以用于根据所述光影动态是顺动、逆动来判断光线是平行、散开或集合,基于检影验光法判断佩戴者眼睛的屈光度;调节模块4还可用于根据所述屈光度调节镜片2显示的3D图像的焦距,使所述焦距与佩戴者眼睛的屈光度匹配,从而可使屈光不正的佩戴者看到清晰地3D图像。这样便于屈光不正的用户使用所述3D眼镜,在不使用其他眼镜辅助的情况下,仍能观看到清晰地3D图像。
为了保证成像单元31获取的佩戴者的左眼图像和右眼的图像均清晰、准确,例如,成像单元31可包括两个摄像头,其中一个摄像头用于采集佩戴者的左眼的图像,另一个摄像头用于采集佩戴者的右眼的图像。这使得佩戴者的双眼均有独立的摄像头进行拍摄,避免在使用一个摄像头同时获取双眼的图像时可能发生的误差,便于准确的确定注视点的位置,从而有利于保证3D影像的观看效果。
由于在3D显示技术中,3D佩戴者的左眼和右眼看到的图像不同,因此,为了便于在镜片2上显示左眼图像和右眼图像,例如,图像采集装置1可包括两个摄像头,这两个摄像头分别从两个位置获取3D显示装置上3D图像,即其中一个摄像头用于获取的用于左眼观看的3D图像,另一个用于获取用于右眼观看的3D图像。
由于自动检测佩戴者的屈光度受外界光线以及佩戴者是否正确佩戴眼镜等因素的影响,难以完全保证佩戴者最终看到的3D图像的清晰度,因此,根据本发明至少一个实施例的3D眼镜还可以包括手动调节单元6,该手动调节单元6包括调节按钮61。手动调节单元6用于手动控制调节模块4调节镜片2显示的3D图像的焦距,调节按钮61用于控制手动调节单元6。使得佩戴者可根据实际需求,调节镜片2显示的3D图像的焦距,从而获得用户满 意的3D图像。由此,这可进一步提高3D图像的观看效果。
本发明至少一实施例还提供了一种3D显示系统,包括:3D显示装置和3D眼镜。该3D显示装置用于显示3D图像;该3D眼镜用于从3D显示装置获取3D图像,使佩戴者眼前出现所述3D显示装置显示的3D图像,并且所述3D眼镜为上述任一技术方案所述的3D眼镜。
所述3D显示装置可以为:液晶面板、电子纸、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。由于在本实施例的3D显示系统中使用的3D眼镜与上述3D眼镜的各实施例提供的3D眼镜相同,因此二者能够解决相同的技术问题,并达到相同的预期效果。
在本说明书的描述中,具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述仅是本发明的示范性实施方式,而非用于限制本发明的保护范围,本发明的保护范围由所附的权利要求确定。
本申请要求于2014年6月19日递交的中国专利申请第201410277076.9号的优先权,在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
