Description

说 明 书
【技术领域】 一种三维立体成像设备和系统
本发明属于三维立体成像技术领域， 涉及一种三维立体成像设备和系统。
【背景技术】
三维显示区别于二维显示最根本的区别就在于， 要用各种方法给观看者带 来视觉的深度感知， 使人自然或者不自然的获得画面中第三维的信息。 对于三 维立体成像技术而言， 还原三维立体空间中的真实物理景深非常重要， 也是使 人眼能够感知到三维立体图像的最关键的因素。
发明人之前在专利申请号为 200910109909.X的中国发明专利， 介绍了一 种三维立体成像方法， 该方法是按照物理景物深度将三维景物纵向分切制作成 若干二维层面， 然后将各二维层面分别同时显示出来形成二维画面， 并使显示 的二维画面的像拼合成原三维景物的像， 在该专利中， 是将一个具有深度信息 的三维景物按照景物深度的方向进行层切， 然后将每一层的三维景物制作成一 个二维层面， 将每一个二维层面显示在一个二维的显示器上面， 显示器的个数 和二维层面的个数相同， 而且各显示器的排列方式如下： 多个显示器分两组相 对排列， 每组各显示器在同一平面内， 且每组各显示器的中心在一条直线上， 每一显示器发出的光线都能通过其相对的显示器反射到其相邻的显示器上。 在 每个显示器的表面都设置有半透半反光学器件， 该半透半反光学器件受电信号 控制， 用于在显示画面时透光不显示画面时反光。 由此使得各显示器所发出的 光线经其他显示器表面上的半透半反光学器件反射成像， 各显示器显示的二维 层面的像拼合成三维立体图像。 ik 明 书
在该专利中， 各显示器如此排列方式出现的一个问题是： 假如各显示器的 大小一样， 而各二维层面在制作时其是按照真实三维景物的大小来制作的， 而 各二维层面的像与人眼的距离比真实的各二维层面与人眼的距离要远， 所以导 致因为视距的原因， 导致人眼看到的各二维层面的像比人眼看到的真实的各二 维层面要小， 则导致图像出现失真的问题， 为了消除少因两组平面显示单元距 离造成的像在人眼中的大小失真， 所以所述各二维平面显示单元的大小不一样， 离人眼最近的二维平面显示单元为成像窗口， 离成像窗口由远及近的各二维平 面显示单元的面积大小分别是成像窗口大小的 N2倍…… 16倍、 9倍和 4倍。
仅仅是分成 4个二维层面， 则第 4个显示器的面积大小是第一个显示器面 积大小的 16倍， 如果是分成 N个二维层面， 则第 N个显示器面积大小是第一 个显示器面积大小的第 N2倍， 这样技术限制了实际应用范围， 其三维景物的分 层数量也得到了极大的限制， 则还原三维景物的真实程度还是会大大折扣。 而 其设备成本在制作起来也是相当高。

显示器。 各平板形液晶显示器 111在同一平面， 且各平板形液晶显示器 111 的 中心在一条直线上。
所述偏光装置 12包括四个平板形半反半透玻璃 121， 各半反半透玻璃 121 的形状相同， 面积为各二维显示器的显示窗口面积的 1 .414 倍。 均为 90cmX160cm的长方形平板半反半透玻璃， 每两个平板形液晶显示器 111之间 设置一平板形半反半透玻璃 121， 且位于四个平板形液晶显示器 111 组成的显 示器列的末端 112设置有一平板形半反半透玻璃 121，人眼 17位于显示器列的 前端 113， 观看时从前端像末端观看。 各平板形半反半透玻璃 121 相互平行， 且每一半反半透玻璃 121与平板形液晶显示器成 45° ， 且半反半透玻璃的反射 面 1211与显示器成 45度角， 半反半透玻璃的透射面 1212与显示器成 145° 。 各半反半透玻璃的边沿 1213与显示器的边沿 1111接触， 相邻的两个显示器的 边沿 1111相接触。
采用上述的三维立体成像设备，还可制作成一个三维立体成像系统，如图 2 所示， 一种三维立体成像系统， 该三维立体成像系统除包括上述的三维立体成 像设备 10外， 还包括像源制作设备 20， 所述像源制作设备 20用于按照物理景 物深度将三维景物纵向分切制作成若干二维层面，所述成像设备 10用于将各二 维层面分别显示出来形成二维画面， 并使显示的二维画面的像拼合成原三维景 物的像。
按照景物深度将三维景物纵向分切制作成若干二维层面的方法在专利申请 号为： 200910109909.X中国发明专利里巳经有详细的记载， 在此不再赘述。与 上述专利不同的是：
又如图 2所示， 所述像源制作设备 20包括画面分切单元 21和画面拼合单 元 22， 所述画面分切单元 21 用于将三维景物按照物理景物深度纵向分切制作 ik 明 书
成若干二维层面，所述画面拼合单元 22用于将各二维层面按顺序拼接成一个二 维画面。
如图 3所示， 该三维立体成像设备 10还包括一多屏显示卡 13和一与多屏 显示卡 13连接的主机 14， 该多屏显示卡 13与多个液晶显示器 111连接。所述 二维画面经主机 14播放后通过所述该多屏显示卡 13 输出给多个液晶显示器 111。
本发明的三维立体成像设备以及三维立体成像系统的工作原理如下： 如图 4所示， 由于半反半透玻璃 121具有在黑色背景下反射光线， 在光亮 的背景下透射反射的作用， 即半反半透玻璃即具有透射光线的功能又具有反射 光线的功能，所以距离人眼最近的平板形液晶显示器 111上显示的二维层面 15， 该液晶显示器 111 发出的光线被离人眼最近的半反半透玻璃 121 反射到人眼 17， 形成直立的与该显示器上显示的二维层面等大的虚像 15， 而距离人眼 17 第二近的平板形液晶显示器 111 发出的光线经距离人眼第二近的半反半透玻璃 121 反射， 再透射过距离人眼最近的半反半透玻璃进入人眼， 形成直立的与距 离人眼第二近的显示器上显示的二维层面等大的虚像 16， 以此类推， 距离人眼 第三近的显示器发出的光线经半反半透玻璃反射后并连续穿透前面的两个半反 半透玻璃进入人眼， 也形成直立的与距离人眼第三近的显示器上显示的二维层 面等大的虚像， 距离人眼最远的显示器发出的光线经半反半透玻璃反射后并连 续穿透前面的三个半反半透玻璃进入人眼， 也形成直立的与距离人眼最远的显 示器上显示的二维层面等大的虚像。 人眼从显示器列的前端 113 向显示列的末 端 112观看， 可以看到多个虚像重叠在一起， 而由于各个虚像的相对位置和各 二维层面的相对位置关系相同， 所以多个虚像拼合在一起即形成具有物理深度 的三维景物的像。 ik 明 书
当三维景物分层越多， 则分切出的二维层面越多， 所需的液晶显示器也越 多， 采用上述成像设备形成的二维层面的像越多， 而且当分切的二维层面数量 越多， 所分切出的二维层面内所包含的虚拟的景深信息越少， 而由于各二维层 面的像的位置关系与二维层面在三维景物中的位置相同， 所以多个二维层面的 像拼合成的三维景物的像所包含的真实的物理景深的信息也就越多， 则该三维 景物的像与原三维景物越接近。
而且由于液晶显示器排成一列， 则只需将液晶显示器的大小设置成一样大 小就可以实现人眼观察到二维层面的像的大小与真实的二维层面的大小相同， 使得拼合出的三维景物的像不会失真。 如此则可以使得显示器的数量增加到很 多， 可以较真实的显示出三维景物的像， 而且设备和系统的成本也大大降低。
需要说明的是：
将上述的半反半透玻璃改换成 45° 玻璃材质的棱镜也是可行的， 所述棱镜 的斜面与液晶显示器呈 45° ， 棱镜的两直面分别与液晶显示器平行和垂直， 由 于玻璃的全反射， 所以该棱镜的斜面可以将与该棱镜接触的显示器发出的光线 反射到人眼， 而棱镜的直面又可以使光线通过， 但是由于光的折射作用， 所以 不与该棱镜接触的其他显示器上显示的其他二维层面的像会出现偏移， 如果不 矫正该偏移量， 则会各二维层面的像的位置关于会发生改变， 则拼合出的图像 则不是原三维景物的像， 所以需要将显示器上显示的二维层面偏移一定的距离。
所述显示器也可为 CRT球面显示器， 但是各显示器的显示窗口大小和形状 相同， 各显示器的显示窗口的中心在一条直线上。
显示器与半反半透玻璃的夹角可为其他角度， 但是较优的是 45° 。
半反半透玻璃的个数可比液晶显示器的个数多， 多出的一个半反半透玻璃 各半反半透光学器件的反射面面积也可为各二维显示器的显示窗口面积的
2倍。总之，各半反半透光学器件的反射面面积大于或者等于各二维显示器的显 示窗口面积的 1 .414倍。
相邻的两个显示器之间可保留一定的距离， 各个距离的大小可不同。
总之： 上述实施例中重点对本发明的设计原理和设计思想做了详细的说明， 同时也列举了一些具体的技术方案对其设计原理和设计思想的支持， 本领域的 技术人员很容易通过上述的说明对本发明做一些简单改进和优化， 毫无疑问的 是， 这些简单的改进和优化应在本发明的保护范围之内。
