Description

全视角全像影像记录方法 技术领域
本发明涉及一种全像影像记录方法，具体涉及一种全视角全像影像记录方法。
背景技术
目前，以新式光学摄影技术在光学全像片上记录所拍摄的影像与传统式光学摄影所制影像相比较而言，所具有的优点为可提供给观看者立体影像与三维的感受。现有的全像片(holographic film)影像制作的基本原理如以下说明(如图1所示)：首先，使用由一影像捕获设备111，例如CCD摄影机，撷取以固定速度旋转的一旋转平台112上的一物体113的影像，并将所摄得的影像经由联机传送至显示面板125。同时使用一发光单元121，例如激光所发射的同调光至一第一反射镜122，第一反射镜122将该同调光反射至一分光镜123，分光镜123将该同调光分成物光(object light)与参考光(reference light)。其中，此物光沿着物光光学路径P1进行，分光镜123将该物光传送至第二反射镜124，第二反射镜124将此物光反射至一显示面板125，显示面板125将该影像捕获设备111所撷取的影像投射且传送至全像底片128上。此外，参考光沿着参考光光学路径P2传送至一第三反射镜126，第三反射镜126将参考光反射至全像底片128上。然后，物光与参考光在全像底片上产生光学干涉，形成许多明暗的干涉条纹(interference fringe)影像。此经曝光后的全像底片经冲洗后为记录物体影像的复合全像片。对此复合全像片只要以参考光为重建光源投射于其上，即可显现物体的三维立体影像。
但是，以上述方式所拍摄与记录的影像仍有缺点与限制，于以上过程中，所拍摄与记录到的为影像捕获设备以固定角度(例如，以某个倾角对X轴固定)所摄得物体旋转360度的影像。故，于影像重建时，观看者并无法看到对X轴变化倾角的影像，且亦无法看到对Y轴变化倾角的影像以及对Z轴变化倾角的影像。因此，以上述传统方式所拍摄与记录的全像影像对于观看者而言，其立体感不足，并非真正的三维立体影像。
因此，目前光学全像影像的记录技术仍有许多不足与缺点，实有进一步改进的必要。
发明内容
为了解决上述现有技术的不足与缺点，本发明提供一种全视角全像影像记录方法，以使所拍摄与记录的影像不仅为围绕目标物体360度的影像，且可记录该目标物体于每一度相对于X轴、Y轴、Z轴倾角所拍摄影像。
本发明提供一种全视角全像影像记录方法，该方法通过一全视角全像影像摄影与记录装置而实施，该全视角全像影像摄影与记录装置包括一全像影像摄影装置与一全像影像记录装置。其中，全像影像摄影装置包含一影像捕获设备与一旋转平台。全像影像记录装置包含一发光单元、一第一反射镜、一分光镜、一第二反射镜、一显示面板、一第三反射镜以及一底片座，该底片座上设有一底片握持器，该底片握持器能够相对于X轴、Y轴及Z轴旋转，该方法包括以下步骤：
使用该影像捕获设备对以固定速度旋转的该旋转平台上放置的一目标物体摄影，并将所摄得的影像经由联机传送至该显示面板上；
使用该发光单元发射同调光至该第一反射镜；
该第一反射镜接收该同调光，并将其反射至该分光镜，该分光镜将该同调光分成物光(object light)与参考光(reference light)；
该分光镜将参考光沿着参考光光学路径传送至该第三反射镜；
该第三反射镜将参考光反射至底片座上的一全像底片上；
该分光镜将物光沿着物光光学路径传送至该第二反射镜；
该第二反射镜将物光反射至该显示面板，并投射且传送至底片座上的该全像底片上。
在本发明的一实施例中，该底片座包括一底盘、一第一旋转装置、一第二旋转装置、一第三旋转装置以及该底片握持器。其中，此第一旋转装置、第二旋转装置以及第三旋转装置设置于该底盘上。该全像底片由该底片握持器牢固地握持，以在旋转时全像底片不会掉落。
在本发明的一实施例中，该第一旋转装置具有一第一马达，其可带动底片握持器以Y轴为旋转轴旋转，从而可使底片握持器与水平方向之 间呈现一倾斜角。该第二旋转装置具有一第二马达，其可带动底片握持器以X轴为旋转轴旋转，从而可使底片握持器与垂直方向之间呈现一倾斜角。该第三旋转装置具有一第三马达，其可带动底片握持器以Z轴为旋转轴旋转，从而可使底片握持器与Z轴方向之间呈现一倾斜角。该底片座由金属或塑料制成，但本发明并不受限于此。
在本发明的一实施例中，该物光光学路径的长度与该参考光光学路径的长度相等。
在本发明的一实施例中，该影像捕获设备为一CCD摄影机。
在本发明的一实施例中，该显示面板为一液晶显示面板。
在本发明的一实施例中，该发光单元为一气体激光发射器、一二氧化碳激光发射器、一液态激光发射器、一固态激光发射器或一半导体激光发射器。
由于在此全像影像记录过程中，全像底片设置于一底片座上，由底片座上所设的底片握持器牢固地握持。底片握持器可以被第一马达、第二马达和第三马达带动，底片握持器能够相对于Y轴、X轴和Z轴旋转，以使该底片握持器上所放置的全像底片不但可记录目标物体旋转360度的影像，而且可记录相对于每一度具有所要求X轴倾角、Y轴倾角和Z轴倾角的影像，故参考光与物光抵达该全像底片上时会彼此干涉，形成具有X倾角、Y倾角以及Z倾角的一全视角全像影像。此经曝光后的全像底片经冲洗后为记录目标物体影像的复合全像片。对此复合全像片可以参考光为重建光源投射于其上，即可显现物体的三维立体影像。

为使审查员方便了解本发明的内容及所能达成的功效，兹配合图式列举具体实施例，详细说明如下：
首先，如图2所示为本发明提供的全视角全像影像记录方法所使用的全像影像摄影与记录装置的概要图。即，本发明提供一种全视角全像影像的记录方法，其通过该全视角全像影像摄影与记录装置而实施。此全视角全像影像摄影与记录装置200包括一全像影像摄影装置210与一全像影像记录装置220。其中，此全像影像摄影装置210包含一影像捕获设备211以及一旋转平台212，旋转平台212上可设置一目标物体213。此全像影像记录装置220包含一发光单元221、一第一反射镜222、一分光镜223、一第二反射镜224、一显示面板225、一第三反射镜226以及一底片座227，底片座227上可设置一全像底片228。
其次，如图3所示为本发明提供的全视角全像影像记录方法所使用的底片座的概要图。如图3所示，该底片座300包括一底盘340、一第一旋转装置310、一第二旋转装置320、一第三旋转装置330以及一底片握持器350。其中，此第一旋转装置310、第二旋转装置320以及第三旋转装置330设置于该底盘340上。该全像底片228由该底片握持器350牢固地握持，以在旋转时全像底片228不会掉落。该第一旋转装置310 具有一第一马达315，其可带动底片握持器350以Y轴为旋转轴旋转，从而可使底片握持器与水平方向之间呈现一倾斜角。该第二旋转装置320具有一第二马达325，其可带动底片握持器350以X轴为旋转轴旋转，从而可使底片握持器与垂直方向之间呈现一倾斜角。该第三旋转装置330具有一第三马达335，其可带动底片握持器350以Z轴为旋转轴旋转，从而可使底片握持器与Z轴方向之间呈现一倾斜角。该底片座300由金属或塑料制成，但本发明并不受限于此。
该全像底片228设置于一底片座300上，由其上所设的底片握持器350牢固地握持。该底片握持器350通过第一旋转装置310、第二旋转装置320以及第三旋转装置330中的第一马达315、第二马达325和第三马达335带动，从而能够以Y轴、X轴、和Z轴为旋转轴旋转，以使该底片座上所放置的全像底片228不仅可记录目标物体213旋转360度的影像，而且可记录相对于每一度具有所要求X轴倾角、Y轴倾角或Z轴倾角的影像。
然后，如图4所示为本发明提供的全视角全像影像记录方法的步骤流程图，包括以下步骤：使用一影像捕获设备211对以固定速度旋转的一旋转平台212上所放置的一目标物体213摄影，并将所摄得的影像经由联机传送至一显示面板225上(步骤410)；使用一发光单元221发射同调光至一第一反射镜222(步骤420)；该第一反射镜222接收同调光，并将其反射至一分光镜223，该分光镜223将该同调光分成物光(object light)与参考光(reference light)(步骤430)；该分光镜223将参考光沿着参考光(第四)光学路径P4传送至一第三反射镜226(步骤440)；该第三反射镜226将参考光反射至一底片座227上的一全像底片228上(步骤450)；该分光镜223将物光沿着物光(第三)光学路径P3传送至一第二反射镜224(步骤460)；该第二反射镜224将物光反射至该显示面板225，并投射且传送至该底片座227的该全像底片228上(步骤470)；以及由于该底片座上的该底片握持器能够相对于X轴、Y轴和Z轴旋转，以使该底片握持器上的该全像底片不但可记录物体旋转360度的影像，而且可记录相对于每一度具有X轴倾角、Y轴倾角和Z轴倾角的影像，故参考光与物光抵达该全像底片上时会彼此干涉，形成具有X倾角、Y倾角以及Z倾角的一全视角全像影像(步骤480)。
由本发明方法所制全像底片经冲洗后为记录物体影像的复合全像片。对此复合全像片可以参考光为重建光源投射于其上，即可显现物体的三维立体影像。
上述由分光镜223经由第二反射镜224至显示面板225、再至全像底片228的光学路径为第三光学路径P3(亦称为物光光学路径)，其路径长度为d3。上述由分光镜223经由第三反射镜226至全像底片228的光学路径称第四光学路径P4(亦称为参考光光学路径)，其路径长度为d4。此P3的长度d3与P4的长度d4相等。
本发明中所使用的全视角全像影像摄影与记录装置200，可以应用于各种全像影像记录系统，例如可用于将全视角全像影像记录于彩虹全像片、反射式全像片、真彩全像片或是积体式全像片等上，但是本发明并不受限于此。
在本实施例中，此发光单元221可以为一气体激光发射器、一二氧化碳激光发射器、一液态激光发射器、一固态激光发射器或一半导体激光发射器，但本发明并不受限于此。又，在本实施例中，该同调光可以为一可见光或一不可见光。影像捕获设备211可以为一CCD摄影机。另外，该显示面板225可以为液晶显示面板。
根据本发明的一实施例，本发明提供的全视角全像影像记录方法在记录影像的实际情况如以下说明。参考图5(a)至图5(c)，其显示本发明实施例的将全视角全像影像记录于全像底片上的概要图。如图5(a)所示，在记录影像时，可控制底片握持器350改变X轴倾斜角度、Y轴倾斜角度以及Z轴倾斜角度，以在全像底片228上记录影像捕获设备211环绕目标物体213的角度为1°时所拍摄影像(参考该图中的A1)。如图5(b)所示，在记录影像时，可控制底片握持器350改变X轴倾斜角度、Y轴倾斜角度以及Z轴倾斜角度，以在全像底片上记录影像捕获设备211环绕目标物体213的角度为2°时所拍摄影像(参考该图中的A2)。综合上述，如图5(c)所示，在记录影像时可以在全像底片228上记录影像捕获设备211环绕目标物体213的角度为1°、2°、3°时所拍摄的影像(参考该图中的A3、A4、A5)。在上述影像记录过程中，在每次曝光之间，可以改变X轴倾斜角度、Y轴倾斜角度以及Z轴倾斜角度，以重复曝光影像于全像底片228上，如此重复此步骤，一直至目标物体213的360 °影像均被记录于全像底片228上为止。
又，本发明提供的所记录全视角全像影像的重建方式如以下说明。参考图6(a)至图6(c)。如图6(a)所示，其显示将LED灯置于全像底片228下，以显示环绕目标物体213的角度为1°时所拍摄的影像(参考该图中的A6)。如图6(b)所示，其显示将LED灯置于全像底片228下，以显示环绕目标物体213的角度为2°时所拍摄的影像(参考该图中的A7)。在上述情形中，使用LED灯作为重建光源从下方照射全像底片228，于同时旋转全像底片228，随着底片与重建光源角度的不同，以获得各种不同影像。如图6(c)所示，其显示随着底片旋转，可以重建环绕目标物体213的角度为1°、2°、3°....时所拍摄影像(参考该图中的A8、A9、A10)。在观看影像时，眼睛如图所示在全像底片上方俯视，随着底片旋转角度不同，首先例如会看到物体的左边影像，然后此全像片旋转至下一角度时，例如会看到物体的右边影像。由于视觉暂留作用，物体的左边影像与右边影像同时存在于观看者的脑海中，其大脑会将此两个二维影像自动理解为一个三维立体全像影像。
综上所述，本发明的特点与优点为，本发明提供的“一种全视角全像影像记录方法”实施时，底片座上所置的全像底片不但可记录目标物体旋转360度的影像，而且可记录相对于每一度具有所要求X轴倾角、Y轴倾角和Z轴倾角的影像，以达成全视角全像影像记录的目的与功效，以记录全视角三维立体影像。因此，本发明具有现有技术无法达成的功效，具有创造性。
以上说明内容仅为本发明一较佳实施例，其并非用来限定本发明实施的范围，故举凡依本发明申请专利范围所述的形状、构造、材质、特征及精神所为的等同变化与修饰，均应包括于本发明的保护范围内。
