Description

一种屏幕投影系统、方法及装置
本申请要求在2015年8月11日提交中国专利局、申请号为201510490762.9、发明名称为“一种屏幕投影系统、方法及装置”以及申请号为201520602648.6、发明创造名称为“一种屏幕投影系统及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示领域，尤其涉及一种屏幕投影系统、方法及装置。
背景技术
本部分旨在为权利要求书中陈述的本申请的实施方式提供背景或上下文。此处的描述不因为包括在本部分中就承认是现有技术。
人类信息传播科技的发展趋势,是不断降低信息熵值，最终使信息熵值趋近于零，也就是尽量逼真复现真实世界。自电影出现以后，显示装置就在不断变革、进步、更新。
传统的屏幕多为单平面幕，但是在实际应用中，平面幕的尺寸有限，无法给观众提供无边界的感觉，所述无边界是指在无边界是指普通观众在正常视域范围内看不到显示装置上显示的画面与现实世界之间的交界处，也就是看不到显示屏幕的边界，使得观众有较强的沉浸感。为了改善观众的无边界感受，目前已存在多种类型的显示屏幕，例如多平面幕、球幕等，由于不同类型的显示屏幕具有不同的形状，因此其投影方式也各不相同。
例如美国专利US8814367B2(授权日为2014年8月26日)公开了一种立体影院，所述立体影院包括相对的两块平面显示屏幕，投影室位于这两块显示屏幕中间，使用半透半反镜将一台投影机的光线同时投影到所述两块平面显示屏幕上。但是半透半反镜成像效果不佳，图像清晰度较低，实际应用中一般很少使用这种投影方式。
球幕电影，又称“圆穹电影”或“穹幕电影”，是20世纪70年代出现的一种大银幕电影。球幕电影的银幕呈半球形、1/3球形或1/4球形等，观众 被包围其中，且一般伴有立体声环绕，使得观众有一定的沉浸感。
球幕由于其特殊的形状，投影方式与平面幕的投影方式有很大不同。在实际应用中，常见的球幕投影方式是正交投影方式，即多个投影机均匀的分布在半球形幕的边缘，所述多个投影机朝向球幕的内壁进行投影。参见图1，该图中五个投影机2均匀的分布在半球幕1的边缘，每个投影机2各自负责一个扇形投影区域，相邻的扇形投影区域之间形成融合区，即相邻两个投影机投射的显示画面的边缘发生重叠，通过边缘融合技术使得两个显示画面融合为一体，所有显示画面融合后形成一个完整的半球画面，覆盖整个半球屏幕。参见图2，该图为球幕的横剖面示意图，图中示出五个投影机2的其中两个投影机投影的范围，图2中投影机M投影的区域以弧线AB表示，投影机N投影的区域以弧线CD表示，虚线表示投影光路。
但是，采用正交投影的方式时，为保证投影机的光路不被观众所遮挡，观众座椅需安装在投影机的投影光路的后面，但是当屏幕形状不是规则的球形时，观众座椅安装在投影光路的后面，无法保证观众获得全角度的显示图像。

具体实施方式
目前出现了一种新型的显示屏幕，所述新型的显示屏幕呈全封闭式或部分封闭式的壳体结构，所述壳体结构的内部用于在水平方向上提供180度至360度视角的连续图像。所述壳体结构包括筒状部，所述筒状部的侧壁在轴向截面上呈平滑的弧线设置或呈直线设置。所述壳体结构还包括一个或两个端部，所述一个或两个端部与所述筒状部采用平滑过渡的方式连接。举例而言，参见图3，在该图中，所述显示屏幕的筒状部为圆柱体，所述圆柱体的侧壁在轴向截面上呈直线设置，两个端部均为半球结构。观众位于圆柱体部分，面朝半球体方向观看显示画面。由于这种新型显示屏幕的筒状部是端部的延伸，当所述端部和所述筒状部均显示图像时，观众的沉浸感非常强，提高了观众无边界的感觉。
但是由于正交投影方法需要观众坐在所有光路的后面，图3中的新型显示屏幕应用正交投影方法进行图像投影时，投影到两侧面的投影机的投影光路会被观众遮挡，从而导致侧面的显示图像不完整。因此，观众看到的只是正前方的完整显示图像，以及侧面的不完整显示图像。这种新型显示屏幕使用正交投影方法时，无法保证观众获得全角度的显示图像，严重影响观众的观看体验。
其他形状的新型的显示屏幕以及不规则的球形显示屏幕同理亦会出现上述情况，因此正交投影方法无法应用到不规则的球形显示屏幕中。
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然， 所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请一具体实现提供一种屏幕投影系统，所述屏幕投影系统包括：显示屏幕、至少两组投影机，每组投影机包括至少一台投影机。
其中，所述显示屏幕呈全封闭式或部分封闭式的壳体结构，所述壳体结构的内壁用于在水平方向上提供180度至360度视角的连续图像。
具体地，参看图3，所述壳体结构包括筒状部31，所述筒状部31的侧壁在轴向截面上呈平滑的弧线设置或呈直线设置。所述壳体结构还包括一个或两个端部32，所述一个或两个端部32与所述筒状部31的两端采用平滑过渡的方式连接。
参看图4，其中，两条平行的虚线中间部分代表筒状部，在本申请一具体实现中，所述筒状部的侧壁在轴向截面上呈平滑的弧线设置；其余部分代表端部。虚线xx’表示所述壳体结构的轴线，所述弧线对应的圆的半径为R，所述弧线距离所述轴线xx’的最大距离为h。所述R可以大于或小于所述h，当所述R大于h或小于h时，所述壳体结构可以是椭球体。
参看图5，其中，两条平行的虚线中间部分代表筒状部，在本申请另一具体实现中，所述筒状部的侧壁在轴向截面上呈直线设置；其余部分代表端部。虚线xx’表示所述壳体结构的轴线。
所述筒状部的横截面可以是圆形、椭圆形、不对称圆形、带圆角的四边形等形状。
无论是图4还是图5，观众(以小黑三角表示)在通常情况下都位于筒状部，并朝向显示屏幕观看显示图像。
本实施例中的屏幕投影系统包括至少两组投影机，所述至少两组投影机在所述显示屏幕中心轴线方向上分层排布，每组投影机分别投影在所述显示屏幕内壁上的一部分，且令所述至少两组投影机的光路避开观众及座椅，所述中心轴线为经过所述显示屏幕中心点且令其左右对称的轴线。
每组投影机根据其投影的区域不同而投影待显示图像横向分割的子显示图像，所述子显示图像拼接起来组成完整的待显示图像。
因此，本申请通过分层设置的投影机，分别在显示屏幕内壁投影部分待显示图像，投影机的光路避开观众座椅。从而保证即便屏幕形状是不规则球形，投影机的投影光路亦不被观众所遮挡，在保证投影效果的同时，适用于多种屏幕。
在本申请另一具体实施例中，所述每组投影机中的每台投影机分别投影在所述显示屏幕内壁的垂直其中心轴线方向上的一部分，每台投影机根据其投影的区域不同而投影所述子显示图像在纵向分割的纵向子显示图像，所述纵向子显示图像拼接起来组成所述子显示图像。
因此，本申请可以根据全景屏幕的尺寸、投影机亮度、镜头焦距等参数，确定每组投影机种所包含的投影机数量，从而保证显示图像的显示效果。本申请投影机安装简便，使用灵活，可以更佳的保证显示图像的显示效果。
下面通过一个具体的实施例来详细解释上述技术方案的投影原理。
参见图6，在该实施例中，所述屏幕投影系统包括显示屏幕61，其中，所述显示屏幕61为全封闭式的壳体结构，所述壳体结构的筒状部为圆柱体，端部为半球体。所述圆柱体的底部“切掉”，呈水平平面，以便安装观众座椅。所述显示屏幕中心轴线方向即为垂直方向。
所述系统包括安装在垂直方向上部的第一组投影机62和安装在垂直方向下部的第二组投影机63，其中，所述第一组投影机62投影在所述显示屏幕61内壁在垂直方向上的下半部分，且投影所述待显示图像下半部分图像；所述第二组投影机63投影在所述显示屏幕61内壁在垂直方向上的上半部分，且投影所述待显示图像上半部分图像。
所述第一组投影机62包括第一投影机621、第二投影机622和第三投影机623。参见图7，所述第一投影机621投影在所述显示屏幕61内壁下半部分的水平方向上的左边区域且投影所述待显示图像下半部分的左三分之一图像。参见图8，所述第二投影机622投影在所述显示屏幕61内壁下半部分的水平方向上的中间区域且投影所述待显示图像下半部分的中间三分之一图 像。参见图9，所述第三投影机623投影在所述显示屏幕61内壁下半部分的水平方向上的右边区域且投影所述待显示图像下半部分的右三分之一图像。
参见图10，所述第二组投影机63包括第四投影机631，所述第四投影机631投影在所述显示屏幕内壁在垂直方向上的上半部分且投影所述待显示图像上半部分图像。
参见图11，所述安装在垂直方向上部的第一组投影机62中的第一投影机621、第二投影机622和第三投影机623投影在所述显示屏幕61内壁在垂直方向上的下半部分且投影所述待显示图像下半部分图像。其中，所述第一投影机621投影所述待显示图像下半部分的左三分之一图像，所述第二投影机622投影所述待显示图像下半部分的中间三分之一图像，所述第三投影机623投影所述待显示图像下半部分的右三分之一图像。所述第二组投影机63中的第四投影机631投影所述待显示图像上半部分图像。
在本申请再一具体实现中，所述屏幕投影系统可以还包括图像源装置，所述图像源装置用于根据所述投影机的数量和位置对待显示图像进行切割，所切割的相邻子显示图像彼此具有融合边，并将切割后的子显示图像分别实时传输至对应的投影机。从而，使所述对应的投影机在所述显示屏幕61的内壁投影对应的子显示图像。
具体地，所述图像源装置通常为图像切割处理软件，可以安装在计算机、服务器等硬件设备上，本申请不做具体限定。其中，所述图像可以是静态的图片，也可以是动态的视频。
本申请还可以通过U盘等设备将切割后的图像分别拷贝至与所述图像对应的投影机，这种方式不需要与图像源装置建立实时连接，投影机的安装位置更为灵活，也不会存在因为投影机与图像源传输中断而无法投影显示图像的问题。
在本申请又一具体实现中，为了使得多个投影机投影的显示画面看上去是一体的，没有拼接的痕迹，相邻子显示图像都有一个相互重叠的融合边， 通过将融合边重叠的画面进行变形校正，使得两个相邻的子显示图像融合为一个图像。
例如，图12为将两个子显示图像切割并融合为一个显示图像的示意图。其中，子显示图像1201显示了字母“A”的上半部分，子显示图像1202显示了字母“A”的下半部分，这两个子显示图像均为矩形，且在所述子显示图像1201的下面的边的附近和所述子显示图像1202的上面的边的附近均设置了一个融合边1203，通过对所述融合边1203内的图像进行变形校正，使得所述子显示图像1201和所述子显示图像1202在所述融合边1203重叠后，形成一个完整的显示图像1204，即一个完整的字母“A”。
在本实施例中，第一组投影机投影的三个近似矩形的显示画面进行边对边融合，即将左三分之一图像、中间三分之一图像以及右三分之一图像通过彼此的融合边进行边对边融合处理，成为所述待显示图像下半部分图像。所述待显示图像下半部分图像与显示屏幕61顶部投影德所述待显示图像上半部分图像进行融合处理。
参见图13，所述待显示图像下半部分图像131变形成的矩形形状显示，其融合边为一条边；而所述待显示图像上半部分图像132变形成的矩形形状显示，其融合边为三条边。因此，将待显示图像下半部分图像131和所述待显示图像上半部分图像132进行融合处理并不能简单的应用边对边融合处理，需要将所述待显示图像下半部分图像131的融合边进行切分处理成为三段，再进行融合处理。
此外，如果所述待显示图像上半部分图像132投影至整个显示屏幕的顶部时，所述待显示图像上半部分图像132变形成的矩形形状显示，其融合边为四条边。需要将所述待显示图像下半部分图像131的融合边进行切分处理成为四段，再进行融合处理。
若所述屏幕投影系统每组投影机的数量增一倍，增加的投影机用于投影所述图3中显示屏幕的空白区域，且增加的投影机可与原投影机前后对称设置，那么显示屏幕显示360度全景图像。
由于如何对显示图像的融合区进行融合属于本领域惯用技术手段，因此本实施例不再详细阐述。
另外，拼接融合的计算过程可以由所述投影机来执行；也可以由计算服务器完成。由投影机或者计算服务器处理所述子显示图像之间的融合区，对所述子显示图像之间进行融合校正，令所述子显示图像拼接组成完整的待显示图像。
参见图14，该图为在所述显示屏幕61形成的半封闭式空间的内部布置了观众座椅的情况下，所述两组投影机的投影情况。其中，所述图14(a)为投影所述显示屏幕61的正视图，所述图14(b)为投影所述显示屏幕61的俯视图，所述图14(c)为投影所述显示屏幕61的左视图。因此，本申请通过分层设置的投影机，分别在显示屏幕内壁投影部分待显示图像，投影机的光路避开观众座椅。从而保证即便屏幕形状是不规则球形，投影机的投影光路亦不被观众所遮挡，在保证投影效果的同时，适用于多种屏幕。
此外，在本实施例中，所述屏幕投影系统的投影机设置了两组，在实际应用中，所述屏幕投影系统还以设置三组投影机，所述三组投影机上中下分层排布。或者，所述屏幕投影系统还可以设置四组或四组以上的投影机，本申请不做具体限定。
在本实施例中，所述屏幕投影系统的两组投影机中，第一组设置了三个投影机，第二组设置了一个投影机。在实际应用中，所述屏幕投影系统的至少两组投影机中，每组至少设置一个投影机，至于具体数量本领域技术人员可以根据实际应用中所述显示屏幕的大小、图像显示区域、观众座位的设置情况等自行设定。

在实际应用中，参见图16，在所述步骤S1之前，所述屏幕投影方法还可以包括步骤S0：根据所述投影机的数量和位置对图像进行切割，所切割的相邻子显示图像彼此具有融合边，并将切割后的子显示图像分别传输至对应的投影机。
当所述至少两组投影机分别将子显示图像投影至所述显示屏幕时，相邻的子显示图像相互重叠的融合边可以融为一体，使得所述子显示图像拼接为一个整体的待显示图像。
