Description

立体观片观屏装置 技术领域
本发明涉及一种观看装置, 尤其涉及一种用于观看立体图片或立体视频的观 片观屏装置。 背景技术
早在一百多年前, 人们就用双镜头相机拍出有视差的左右两幅照片, 用特制 的观片器观看立体 (3D) 画面, 这种方式一直流传至今。 其工作原理是, 利用双 镜头相机模拟人的两眼的位置, 对景物分别拍摄两幅有视差的照片。 然后通过观 片器, 使人的左眼仅能看到左镜头拍摄的照片, 右眼仅能看到右镜头拍摄的照 片, 通过大脑合成一幅图像, 产生立体视觉效果。
人们在观看物体时, 双眼的聚焦和视线向内夹角会随物体远近自然调节。 通 常夹角从远处接近 0° 到近处的约 12° 为最佳观看距离。 当人的眼睛聚焦在某一距 离时, 其双眼自然调节观看夹角的范围是有限的。 如果景象需要双眼调节的夹角 超过此范围时, 就需要人用较大的力进行调节, 易使眼睛感觉疲劳和不适。
由于双镜头拍摄的视差效果, 这被拍摄物体显示在相对观看距离固定的左右 两张照片上的间距关系是: 远处的物体间距大、 近处的物体间距小 (如图 1A和图 1B所示) 。 从图 1A和图 1B中可以看出, 物体 C离双镜头照相机 10的距离最远, 物 体 A离双镜头照相机的距离最近。 反映到两幅照片上, 左照片 10A和右照片 10B上 显示的物体 C之间的距离最大, 左照片 10A和右照片 10B上显示的物体 A之间的距 离最小, 左照片 10A和右照片 10B上显示的物体 B之间的距离介于两者之间。
如果观片器设计成适宜于观看远景物 (例如物体 C) (或较大尺寸照片) , 那么用这样的观片器观看具有近景物 (例如物体 A) 时, 两幅画面就会合拢过 头, 无法看到正确的立体景象。 这时往往需要人的双眼使用双眼交叉法 (俗称 "头鸡眼"法) 调节视线向内夹角, 使近景物能正确合拢, 看到立体效果。 简单 地说, 适于观看远景物的观片器, 不适于观看近景物。 反之, 如果观片器设计成 适宜于观看近景物 (例如物体 A) (或较小尺寸照片) , 就不适于观看远景物。 因此, 传统的立体观片器无法同时兼顾各种由于拍摄景物的远近、 镜头数据差 异、 照片或显示屏尺寸差异等原因, 而形成显示在左右画面景物间距相差较大的 问题。
再一方面, 由于人的双眼的瞳距因人而异, 有时相差甚多, 一种规格的观片 器更无法满足不同人的需要。 使用不适合的观片器观看立体图像往往容易产生眼 睛疲劳、 头晕甚至恶心等影响健康的现象。 这也是立体观片不能普及的重要原 因。 发明内容

在描述本发明的立体观片观屏装置之前, 先描述一下立体成像以及双眼重合 的工作原理, 以有助于理解本发明。
众所周知, 光线从空气进入到密度不同的另一种的透光物体 (例如玻璃、 有 机玻璃、 光学树脂等) 时, 会产生折射现象。 图 2示出了光线从空气进入到有机玻 璃时产生的折射现象的光路图。
利用这一原理, 当人眼通过棱镜观物体 1时 (请参见图 3 ) ,经过光线的折射, 人感觉到的物体 1的位置移动到物体 2, 也就是见到的物体会向棱镜薄的方向位 移。 我们常用的放大镜 (凸透镜) 可以看成无限多个连续变化的棱镜拼接而成。 放大镜中心点对应的棱镜夹角为 0度。 也就是说, 通过放大镜的中心点向外看到的 物体不会产生位移。 自中心点向外延伸, 其对应的棱镜夹角越来越大, 也就是光 线透过放大镜的位置离中心点越远其折射角 (棱镜夹角) 也越大, 见到的物体位 移也越大。
图 4示意性地示出了通过放大镜看到的物体的位移的情况。 图 4中 41为放大 镜。 当人眼通过放大镜观看物体 1时, 如果将放大镜 41向左移动, 根据上述的原 理, 由于其对应的棱镜夹角变小, 见到的物体 2离物体 1的位移越小; 反之, 如果 将放大镜 41向右移动, 由于其对应的棱镜夹角变大, 见到的物体 2离物体 1的位移 越大。 也就是说, 根据这一原理, 可以通过移动放大镜的位置来改变物体的位 移。 如果同时调节左右眼的放大镜, 则可以改变两眼看到的物体的间距。 本发明 就是基于这一原理而设计的。
下面将结合图 6至图 10详细描述本发明的立体观片观屏装置的具体实施例。 请参见图 6,本实施例中的立体观片观屏装置包括本体 61、 目镜 62L、 62R、 暗 箱 63等。 本体 61分成两个部分, 前部设置左目镜 62L和右目镜 62R; 后部形成置片 架 (或置屏架) 64。 暗箱 63设置于本体 61的中部, 即暗箱 63位于目镜 62L、 62R与 置片架 64之间。 置片架 64上可以放置照片或者具有显示屏的手机、 数码相机等。
在目镜 62L、 62R上设置有目镜调节手柄 64L、 64R。 为更好地解释和示出目 镜调节手柄 64L和 64R的结构, 请结合参见图 7。 如图 7所示, 在本体 61上开设有滑 槽 65, 目镜 62L、 62R置于该滑槽中 65, 且目 62L、 62R可沿该滑槽 65左右滑动。 在 目镜 62L、 62R上分别设置目镜调节手柄 64L、 64R。 在左目镜 62L和右目镜 62R之 间设置一个摇臂 66,该摇臂 66的中心点通过一螺钉 67固定在本体 61上, 固定时, 需 要确保摇臂 66能自由转动。 在摇臂 66的两端分别开设通孔, 两根 (钢丝) 连杆之 一 68L的一端连接左目镜 62L上, 另一端连接到摇臂 66—端的通孔中。 同样, 两根 (钢丝) 连杆之另一 68R的一端连接右目镜 62R上, 另一端连接到摇臂 66另一端的 通孔中。 如此形成了可以使左目镜 62L和右目镜 62R连动的目镜调节机构。 当然, 这里仅通过一个具体实施例列举了目镜调节机构的一个具体实例, 可以理解, 本 领域普通技术人员可以根据上述的目的, 设计出各种目镜调节机构。 例如本实施 例中, 可以仅保留一个调节手柄; 也可以省略摇臂 66等部件, 直接通过调节手柄 来调节; 还可以采用丝杆等连动方式, 在此不再一一列举。 即使未被列举, 这些 机构也应当被包含在本发明的保护范围内。
请同时参见图 6和图 8,为了显示出暗箱 63的结构, 图 8中以虚线形式作了图 示。 如上所述, 暗箱 63设置于本体 61的中部。 在本实施例中, 置片架 64被设计成 与本体 61成为一体。 在另外的实施例中, 置片架 64也可以单独制作, 并通过连接 元件与本体 61相连接即可。 置片架 64可以设置一个槽口, 用于放置照片或者小型 视频播放器 (例如 MP4或带视频播放的手机) 。 暗箱 63位于目 62L、 62R与置片架 64之间。 暗箱 63的一端可以制成开放的形式, 并与设置有目镜 62L、 62R的本体 61 相连接; 另一端开设有左视孔 63L和右视孔 63R。 左视孔 63L与左目镜 62L相对应, 确保通过左目镜 62L看到且仅能看到左面的图像; 右视孔 63R与右目镜 62R相对 应, 确保通过右目镜 62R看到且仅能看到右面的图像。
在使用本实施例的立体观片观屏装置时, 使用者可以通过移动调节手柄 64L 或 64左右移动目镜 62L、 62R, 从而实现重合度调节, 实现了同一观片观屏器即可 以看远景物, 又可以看近景物, 还可以适应不同瞳距的人使用。
在本发明的另一个实施例中, 在上一实施例的基础上, 还可以增设一个位移 扩展器 9。 该位移扩展器的结构如图 9和图 10所示。 请同时参见图 9和图 10,它包括 一个扩展器本体 91和棱镜组 93L、 93R。 扩展体本体 91上开设有观看孔 92L、 92R, 左棱镜组 93L设置于左观看孔 92L区域, 右棱镜组 93设置于右观看孔 92R区域。 棱 镜组包含增合棱镜和减合棱镜。 请具体参见图 10,图 10示出了其中右棱镜组 93R的 结构, 右棱镜组 93R包括增合棱镜 93R1以及减合棱镜 93R2。 在扩展器本体 91上通 过滑槽等方式设置增合棱镜 93R1和减合棱镜 93R2,使增合棱镜 93R1和减合棱镜 93R2可以在滑槽中自由滑动。 在增合棱镜 93R1和减合棱镜 93R2上各自设置一个棱 镜调节手柄 94R1、 94R2。 通过棱镜调节手柄 94R1、 94R2可以使增合棱镜 93R1和 减合棱镜 93R2在滑槽中左右滑动。 左棱镜组的结构与右棱镜组相同, 在此不再赘 述。
位移扩展器可以与图 6中的立体观片观屏装置组合使用, 组合的方式请参见 图 11所示。 在扩展器本体 91左右两端分别延伸出一接耳 95 ; 在接耳 95上开了通 孔; 同样, 在本体 61的相应位置也开设一对螺孔 65, 通过螺钉 97把位移扩展器连 接到本体 61上, 以使位移扩展器位于目镜 62L、 62R的前方, 且使左观看孔 92L对 应左目镜 62L, 左观看孔 92R对应右目镜 62R。
位移扩展器的工作原理, 请参见图 5A和图 5B所示。 图 5A示出了增合棱镜 93R1的示意图, 图 5B示出了减合棱镜 93R2的示意图。 如图 5A所示, 增合棱镜 93R1的棱镜夹角方向与放大镜的棱镜夹角方向一致, 也就说是, 增合棱镜 93R1产 生的物体位移与放大镜产生的位移方向一致, 从而实现两个位移的叠加 (即此处 称之为增合) 。 反之, 如图 5B所示, 减合棱镜 93R2的棱镜夹角方向与放大镜的棱 镜夹角方向相反, 也就说是, 减合棱镜 93R2产生的物体位移与放大镜产生的位移 方向相反, 从而实现两个位移的部分或全部的抵消 (即此处称之为减合) 。 因 此, 通过增合棱镜和减合棱镜可以进一步对看到的图像的位移进行调整。
下面请参见图 12,在图 12中示出本发明的立体观片观屏器的再一个实施例。 如 图 12所示, 在该实施例中, 包括一个位移扩展器 9和一个暗箱 12。
位移扩展器 9的结构与图 9中所示的位移扩展器 9相同, 因此在此不再重复。 暗箱 12是一个一端可以制成开放形式的箱体其开放的一端位移扩展器 9相连, 另一 端开设有左视孔 12L和右视孔 12R。 左视孔 12L与位移扩展器 9的左观看孔 93L相对 应, 确保通过左观看孔 93L看到且仅能看到左面的图像; 右视孔 12R与位移扩展器 9的右观看孔 93R相对应, 确保通过右观看孔 93R看到且仅能看到右面的图像。
图 12所示的实施例适用于观看电视屏幕、 计算机屏幕或者较大的照片或图片 等。 使用时仅需将增合棱镜移入到观看孔中即可。
