Description

翻页装置、方法和扫描装置 技术领域
本公开实施例属于扫描领域，具体涉及一种翻页装置、方法和扫描装置。
背景技术
随着互联网技术的快速发展，学习、工作和阅读方式逐渐由纸质方式转变成电子方式，电子化的益处是显而易见的。例如在电子书领域，电子化使得不用随身携带沉重的书籍，而只需要一个移动设备就能够随时随地尽情地阅读感兴趣的资料。又如在档案管理领域，纸质档案所面临的急迫问题包括纸质档案的存放、保管和检索，一方面，纸质档案的存放需要占据大量的空间，如若保管不当，容易导致遗失、损毁，特别是在数量较大的情况下，如何快速找到所需的档案也成为重大的挑战。而电子化能够在很大程度上解决这些问题，电子化档案占据空间小，并且保管容易、检索方便。
然而，如何将诸如书籍、档案之类的对象转换成电子格式仍旧面临着巨大挑战。现在的技术大多采用对书籍档案逐页拍照的方式来使其电子化，且翻页过程多采用人工的方式，这样的工作方式明显效率不高，而且人为的方式具有不确定性，容易造成纸张的损坏。
近年来，出现了能自动翻书扫描的仪器，但在翻书扫描装置中翻页是一个比较难解决的问题，由于书籍档案的纸张不同，尤其是古籍档案年陈久远，许多纸张都十分脆弱，不小心就会将其损坏，造成重大的损失。

还需要说明的是，以下实施例中所提供的图示仅以示意方式说明本公开的基本构想，图式中仅显示与本公开中有关的组件而非按照实际实施时的组件数目、形状及尺寸绘制，其实际实施时各组件的型态、数量及比例可为一种随意的改变，且其组件布局型态也可能更为复杂。
另外，在以下描述中，提供具体细节是为了便于透彻理解实例。然而，所属领域的技术人员将理解，可在没有这些特定细节的情况下实践所述方面。
本公开实施例提供一种翻页方法。本实施例提供的翻页方法可以由一计算装置来执行，该计算装置可以实现为软件，或者实现为软件和硬件的组合，该计算装置可以集成设置在服务器、终端设备等中。
以下，参考附图对根据本公开实施例的技术方案进行详细的描述。应当注意，在以下的描述中，术语“扫描对象”是指其上能够记录信息的载体。扫描对象上所记录的信息通过扫描装置的扫描操作被转换为数字信息。扫描对象例如包含普通纸、铜版纸、塑料片，等等。此外，虽然在以下的描述中，以书本的纸张作为扫描对象的示例来描述本公开，但是扫描对象例如可以是报纸、照片、票据等等。
在以下的描述中，虽然以吸盘为例描述了力施加装置，但是向扫描对象施加的使得当前扫描对象(第一扫描对象)与其后的扫描对象(第二扫描对象) 分开的力不限于吸盘所施加的吸附力，而是可以包括例如静电吸附力、磁吸附力、仿生吸附力中的一个或者多个。并且所生成的力不限于吸附力，也可以是施加在纸张上的推力。
首先，参考图1，描述根据本公开实施例的翻页装置100。在图1中，101为吸盘安装部、102为夹持机构、103为扫描支撑平台、104为水平移动平台、105为机架、106为升降机构、107为扫描对象、108为翻页模组、109为左侧防反弹机构、110为压页机构，并且111为右侧防反弹机构。
在本公开实施例中，将图1中的左右方向定义为x方向，将上下方向定义为y方向，并且将垂直于xy平面的方向定义为z方向。
如图1所示，水平移动平台104被安装在机架105的底板上，并且水平移动平台104可以例如沿导轨在x方向上移动。此外，水平移动平台104上固定安装有升降机构106，扫描支撑平台103被安装在升降机构106上。因此，扫描支撑平台103在升降机构106的作用下可以实现y方向上的移动。另外，扫描支撑平台103可以跟随水平移动平台104在x方向上移动。如此，根据本公开实施例的扫描支撑平台103能够在x方向和y方向这两个自由度上运动。
另外，机架105上安装有翻页模组108，翻页模组108与安装有吸盘的吸盘安装部101相连，翻页模组108可以沿设置在机架105上的导轨往返运动。
另外，扫描支撑平台103上安装有左侧防反弹机构109和右侧防反弹机构111，并且在机架105上还安装有压页机构110。
在进行翻页操作时，使用夹持机构102夹紧扫描对象107，水平移动平台104向右移动，以使得扫描对象107被移动至预定位置。此外，压页机构110动作以使得压页机械手旋转至预定位置，然后升降机构106动作，推动扫描对象107向上移动，直至接触压页机械手后停止。如此，能够在x方向和y方向上将扫描对象107移动至预定位置。
接着，参考图2和图3描述对于较硬的纸张和较软的纸张的翻页过程。
参考图2，描述对于较硬的(不能弯折或不允许弯折)纸张的翻页过程。对于较厚的纸张，由于其无法弯折，因此其翻页过程如下：
S201：翻页模组108动作，带动吸盘安装部101向下移动，至吸盘安装部101上的吸盘接触扫描对象107后停止。
S202：压页机构110动作，使得压页机械手向上运动至预定位置后停止，以远离扫描对象107。随后，吸盘安装部101、翻页模组104和水平移动平台104协调动作，实现页面的翻开动作，直至到达图像采集位置。
具体地，在翻页过程中，翻页模组104(吸盘)沿固定轨道移动的同时，吸盘能够沿着z方向的轴转动，并且水平移动平台104在x方向上移动扫描对象，以使得在翻页过程中纸张不会发生弯折。吸盘沿着z方向的轴转动例如可以通过吸盘安装部101与翻页模组104铰接来实现。
S203：压页机构动作110，压页机械手向下运动直至接触扫描对象107后停止。图像采集完成后，吸盘松开已经拾取的页面，同时右侧防反弹机构111动作，右侧压页杆向左运动，将该页面推至扫描对象107左侧并压紧。
S204：左侧防反弹机构109动作，左侧压页杆压紧左侧已翻的页面，然后，右侧防反弹机构111动作，右侧压页杆回到初始位置。至此，完成一页扫描资料的翻页动作。
参考图3，描述对于较软的(能够弯折的)纸张的翻页过程。由于较软的纸张能够弯折，因此其翻页过程如下：
S301：翻页模组108动作，带动吸盘安装部101向下移动，至吸盘安装部101上的吸盘接触扫描对象107后停止。
S302：压页机构110动作，使得压页机械手向上运动至预定位置后停止，以远离扫描对象107。随后，翻页模组108动作，带动已经拾取的页面沿模组向上移动至图像采集位置。
S303：压页机构动作110，压页机械手向下运动直至接触扫描对象107后停止。图像采集完成后，吸盘松开已经拾取的页面，同时右侧防反弹机构111动作，右侧压页杆向左运动，将该页面推至扫描对象107左侧并压紧。
S304：左侧防反弹机构109动作，左侧压页杆压紧左侧已翻的页面，然后，右侧防反弹机构111动作，右侧压页杆回到初始位置。至此，完成一页扫描资 料的翻页动作。
在根据本公开的实施例中，翻页装置100被配置为使成册的扫描对象107中的第一扫描对象和第二扫描对象分开一角度。
成册的扫描对象可以是其本身处于成册的状态，例如成册的书本。可替代地，成册的扫描对象可以是本身为分散的扫描对象，但其通过夹持机构102夹持其一侧而成为成册的状态。
在本公开的实施例中，第一扫描对象可以是当前需要翻开的页面，并且第二扫描对象可以是与第一扫描对象相邻的页面。
另外，翻页装置100通过如上所述的操作将第一扫描对象和第二扫描对象分开一角度，该角度例如为60°，90°，110°或者其他合适的角度，以便于后续的成像操作。
根据本公开实施例的翻页装置100包括作为力施加装置的示例的吸盘。具体地，吸盘被安装在吸盘安装部101上。在翻页操作过程中，吸盘吸附第一扫描对象，以向第一扫描对象施加使得第一扫描对象与第二扫描对象分开的力。在本公开的实施例中，使得第一扫描对象与第二扫描对象分开的力是吸盘产生的吸附力。
另外，根据本公开实施例的翻页装置110还包括作为力施加装置移动部的示例的翻页模组108，翻页模组108沿着固定的轨道移动。具体地，在本示例性实施例中，固定轨道被设置在机架105上，并且与扫描对象107所在平面成预定的角度，该角度例如为35°，45°或者其他合适的角度。
在本示例性实施例中，吸盘经由吸盘安装部101被连接到翻页模组108，从而在翻页模组108沿着固定轨道移动的过程中，带动吸盘沿着所述固定轨道移动。如上所述，由于固定轨道与扫描对象所在平面相交，因此在翻页模组108带动吸盘沿着固定轨道往返运动时，能够使得吸盘所吸附的第一扫描对象与第二扫描对象分开，并且分开的角度可以通过翻页模组108的移动量来控制。
在本公开的实施例中，通过将翻页模组108安装在机架105上，并且翻页模组108被设置为沿着固定的轨道移动，这能够提高整个扫描装置的稳定性。 具体地，在扫描过程中，对于每次翻页操作，翻页模组108需要往返一次以翻开第一扫描对象。对于高速扫描，翻页模组108的移动行程长，驱动翻页模组108的电机速率高，因此设置固定的轨道能够最大限度地提高扫描装置的稳定性，降低扫描过程的噪音，并且降低驱动翻页模组108的电机的驱动复杂程度。
在翻页模组108带动吸盘沿着固定轨道移动的情况下，对于轨道上的预定位置，吸盘的位置也是固定的。因此，随着翻页过程的进行，已翻页面的页数增加，并且未翻页面的页数减少，从而导致翻页模组108需要下移更长的距离以与扫描对象107接触。在这种情况下，如果在翻页过程中保持扫描对象不动，吸盘与第一扫描对象接触的位置会不断靠近页面的边缘，最终可能无法与页面接触(吸盘被移动到扫描对象的范围之外)。
因此，在本公开的实施例中，翻页装置100还包括扫描对象移动部，扫描对象移动部由图1中所示的水平移动平台104和升降机构106配置。具体地，水平移动平台104被安装在机架105的底板上，并且水平移动平台104可以沿导轨在图1的x方向上移动。此外，水平移动平台104上固定安装有升降机构106，扫描支撑平台103被安装在升降机构106上，因此，扫描支撑平台103在升降机构106的作用下可以实现在图1中的y方向上的移动。如此，扫描对象107能够在第一方向(x方向，与扫描对象107所在平面平行的方向)和第二方向(y方向，垂直于扫描对象107所在平面的方向)上移动。
在翻页过程中，翻页模组108带动吸盘向下移动，以使得吸盘与第一扫描对象接触。在本公开的实施例中，需要吸盘与第一扫描对象的接触位置在靠近第一扫描对象边缘的位置处，如此才能够使得第一扫描对象与第二扫描对象有效地分离。通过实验发现，当吸盘与第一扫描对象的接触位置在距离页面边缘6cm以内的范围时，第一扫描对象与第二扫描对象的分离成功率能够到达96％以上。
因此，在本公开的实施例中，在开始翻页操作的定时处，扫描对象移动部(水平移动平台104和升降机构106)将扫描对象107移动到如下的位置处，该位置使得吸盘的吸附力的作用位置距离第一扫描对象的边缘在预定阈值范围 内。预定阈值例如可以是10cm，8cm，6cm，4cm或者其他合适的值，但是在本公开的实施例中，该预定阈值被设置为6cm，如此能够保证96％以上的分离成功率。
如上所述，对于翻页模组108在固定轨道上的固定位置，吸盘的位置是确定的。因此，只要通过水平移动平台104和升降机构106移动扫描对象107，就能够确保吸盘与第一扫描对象的接触位置。具体地，在x方向上的位置固定的情况下，沿+y方向移动扫描对象107能够增大与页面边缘的距离，并且沿-y方向移动扫描对象107能够减小与页面边缘的距离。此外，在y方向上的位置固定的情况下，沿+x方向移动扫描对象107能够增大与页面边缘的距离，并且沿-x方向移动扫描对象107能够减小与页面边缘的距离。
在本公开的实施例中，将翻页模组108设置为在一个方向上移动，并且将扫描对象设置为在两个自由度上移动，这对于提高扫描装置的稳定性和效率是特别有利的。这是因为在翻页过程中，扫描对象107的移动量小，并且相较于翻页模组108的移动速率低，因此能够有足够的时间在两个方向(x方向和y方向)上移动扫描对象107。如此，在减小了翻页模组108移动所需时间的同时能够最大限度地保证扫描装置的稳定性，并降低电机驱动时的噪声。
应当理解，虽然以上描述了在两个方向(x方向和y方向)上移动扫描对象107以将吸盘的吸附力的作用位置控制为距离第一扫描对象的边缘在预定阈值范围内，但是本发明不限于此。根据本公开实施例的扫描装置还可以仅仅在x方向或者y方向上移动扫描对象107来实现上述效果。具体地，随着翻页过程的进行，可以仅仅在+x方向上移动扫描对象107。可替代地，可以仅仅在+y方向上移动扫描对象。这能够实现相同的效果，即将吸盘的吸附力的作用位置控制为距离第一扫描对象的边缘在预定阈值范围内。根据本公开实施例的一种具体实现方式，在开始翻页操作的定时处，扫描对象107在x方向上被移动到第一预定位置处。也就是说，对于每次翻页操作，在开始翻页时扫描对象107在x方向均被移动到固定的位置。如此，一方面减少了控制的难度，另一方面则只需要在y方向上保证扫描对象107的位置，就能够保证吸盘与当前页面的接触 位置。
在本公开的实施例中，不必每次都将扫描对象107移动到y方向上的预定位置，这是因为随着翻页过程的进行，吸盘与第一扫描对象的接触位置会向着页面边缘移动，如此，能够提高页面分离的成功率。因此，在本公开的实施例中，只有当扫描对象107的第一扫描对象距y方向上的预定位置的距离大于预定值时，扫描对象107才被移动到该第二预定位置处。
该预定值可以根据吸盘与第一扫描对象的接触位置距离页面边缘的阈值和固定轨道与扫描对象107所成角度来确定。例如，在第一扫描对象距y方向上的预定位置的距离为所述预定值时，吸盘的吸附位置刚好处于第一扫描对象的边缘位置。如此，通过逐步而不是连续地移动扫描对象107，进一步减少了扫描对象107的控制量。
根据本公开实施例的一种具体实现方式，翻页装置100包括防反弹装置109和111，左侧防反弹机构109和右侧防反弹机构111在第一扫描对象和第二扫描对象被分开预定角度之后按压已翻页的扫描对象(具体操作参见前文的描述)。
在根据本公开的实施例中，防反弹装置109和111被布置在扫描装置的一侧，具体地，防反弹装置109和111被布置在远离操作者进行操作的一侧，从而防止防弹装置109和111对操作者的操作的干扰。
根据本公开实施例的一种具体实现方式，防反弹装置109和111通过旋转按压的方式按压已翻页的扫描对象，并且防反弹装置109和111的旋转角度根据扫描对象107的已翻页的页数或者在y方向上的总移动距离、在x方向上的移动距离或者在y方向上的总移动距离来调整。在这种情况下，已翻页的页数、在x或y方向上的总移动距离与已翻页的页面的厚度相对应。在本示例性实施例中，x方向上的移动距离是指与x方向上的预定位置的距离，并且y方向上的总移动距离是指扫描对象在y方向上的总移动量。
具体地，随着翻页过程的进行，已翻页面的页数增多，厚度增大，因此需要减小防反弹机构409和411的转动角度。根据一个实施例，扫描装置可以对已翻页页数进行计数，而对于特定类型的纸张，其厚度基本均匀，因此，已翻 页页数与已翻页页面的厚度对应。如此，能够直接根据已翻页的页数来调整防反弹装置的转动角度。
根据另一个实施例，防反弹装置的转动角度的调整量与扫描对象107在y方向上的总移动量相关，在本公开的实施例中，y方向上的总移动量指示升降机构106在y方向上的驱动量，并且对应于已翻页面的页数和厚度，如此，能够间接地根据扫描对象在第二方向上的总移动距离来调整防反弹装置的转动角度。这种间接的方式是特别有利的，因为扫描对象在y方向上的总移动量能够通过驱动升降机构106的电机的脉冲数容易地获得。
根据另一个实施例，在扫描对象仅能够在x方向上移动的情况下，为了实现吸盘位置距离页面边缘预定阈值范围内，此时扫描对象需要根据其已经翻页的厚度而在x方向上移动。也就是说，在这种情况下，翻页装置根据在第一方向(x方向)上的移动距离来调整防反弹装置的转动角度。
在以上，已翻页页数、扫描对象在第一方向、第二方向上的总移动距离均与已翻页厚度相关联。
根据本公开实施例的一种具体实现方式，扫描对象107通过夹持机构102被固定于扫描支撑平台103。在根据本公开的实施例中，根据扫描对象107在y方向上的总移动量来使得夹持机构102进行转动。
具体地，如图4所示，随着翻页操作的进行，已翻页面会在靠近夹持部位的位置处形成隆起(书肚)，这会造成页面的弯曲，从而对后续的成像过程造成影响，特别是在扫描对象107较厚的情况下，甚至出现无法翻页的状况。因此，在根据本公开的实施例中，随着扫描对象107向上移动(翻页过程的进行)，夹持机构102能够转动以减小书肚。在如图4所示的翻页过程中，夹持机构102能够逆时针转动，从而减少书肚。
根据一个实施例，翻页装置直接根据书肚的大小来使得夹持机构转动或者调整加持机构102的转动量。书肚的大小一般与已翻页页面弯曲的曲率半径相关，如此，通过检测已翻页页面弯曲的曲率半径即可得到书肚大小。
根据另一实施例，可以根据扫描对象在第二方向上的总移动距离来使得夹 持机构102转动，也就是说，夹持机构102的转动量与扫描对象107在竖直方向上的总移动量相关。具体地，扫描对象107在竖直方向上的总移动量越大，夹持机构102的转动量也越大，如此能够减小书肚(隆起)的产生。
根据又一个实施例，在扫描对象仅能够在x方向上移动的情况下，为了实现吸盘位置距离页面边缘预定阈值范围内，此时扫描对象需要根据其已经翻页的厚度而在x方向上移动。也就是说，在这种情况下，翻页装置根据在第一方向(x方向)上的移动距离来使得夹持装置转动。
在以上，书肚大小、扫描对象在第一方向、第二方向上的总移动距离均与已翻页的厚度相关联。
根据本公开实施例的一种具体实现方式，在力施加装置移动部沿固定轨道移动的同时，扫描对象移动部在图1中的x方向上移动扫描对象，并且力施加装置(吸盘)能够沿着z方向的轴转动，以使得在翻页过程中第一扫描对象不会发生弯折。
对于较软的纸张，其在翻页过程中能够发生弯折以提高翻页效率，然而，对于较厚的纸张，其不能够发生弯折，因此需要水平移动平台104和吸盘的配合运动以使得纸张不发生弯折。具体地，在本公开实施例中，水平移动平台104能够在x方向上移动，并且吸盘安装部101可转动地安装在翻页模组108上，以使得在翻页过程中能够使得吸盘的力施加方向改变。也就是说，在这种情况下，纸张发生围绕书脊部分的转动而不会弯折。
换句话说，翻页模组108和水平移动平台104的运动能够被控制，以使得所翻页面在翻页过程中不发生弯折。这种控制对于硬壳书籍是特别有用的。可替代地，对于较软的纸张，在翻页过程中，水平移动平台104可以不移动，而翻页模组108直接沿着固定导轨移动。这种情况虽然使得页面发生弯折，但是能够提高翻页效率，这对于较软的纸张特别有利。
根据本公开实施例的一种具体实现方式，翻页装置100还包括位置传感器，位置传感器被配置为使得在第一扫描对象与第二扫描对象分开角度达到预定值时，使翻页动作停止。
在翻页过程中，需要将第一扫描对象和第二扫描对象分开预定角度。在本公开的实施例中，通过位置传感器来实现位置的控制。如图5所示，该位置传感器502可以是设置在吸盘安装部503上的光感传感器。
光感传感器通常是指能敏感由紫外光到红外光的光能量，并将光能量转换成电信号的器件。光感传感器主要由光敏元件组成，主要分为环境光传感器、红外光传感器、太阳光传感器、紫外光传感器等等，在本公开实施例中，光传感器采用环境光传感器。
此外，如图5所示，与吸盘501相比，该光感传感器被安装在更靠近扫描对象107的边缘的位置处，并且在开始翻页操作时，当吸盘501与第一扫描对象接触时，光感传感器被设置为被第一扫描对象遮挡，即，在开始翻页操作时，光感传感器在扫描对象的范围内。
随着翻页过程的进行，吸盘501在吸附第一扫描对象的情况下沿斜向上的方向移动，使得第一扫描对象和第二扫扫描对象之间的角度不断增大，当二者之间的角度达到预定值时，此时第一扫描对象被展平。当吸盘501继续带动第一扫描对象移动时，吸盘501会相对于第一扫描对象发生相对滑动，从而使得光感传感器从第一扫描对象漏出，即不被第一扫描对象遮挡。
在这种情况下，光感传感器发送信号，以使得带动翻页模组108移动的电机停止驱动，从而实现了将第一扫描对象和第二扫描对象之间的角度保持在预定值，并且能够确保第一扫描对象和第二扫描对象的平整，以便于后续的成像操作。
如此设置位置传感器502是特别有利的，其能够对于不同尺寸的扫描对象107都确保其被翻页到合适的位置。例如，对于A4尺寸的纸张和A3尺寸的纸张，其被展平翻页模组所需要移动的距离是不同的，通过这种方法能够确保对于任何尺寸的纸张都能够移动到合适的位置，并且对于同一尺寸的纸张，其分开的角度大致相等。
虽然以上以光感传感器为例描述为位置传感器，但是其他类型的传感器也是可能的。例如，位置传感器还可以是激光二极管等等，其只要能够检确定第 一扫描对象与第二扫描对象分开角度是否达到规定即可。
参见图6，本公开实施例还提供了一种与上述翻页装置对应的翻页方法，该方法用于使成册的扫描对象中的第一扫描对象和第二扫描对象分开一角度。该翻页方法包括：
S601：在第一方向和第二方向上将扫描对象移动到预定位置，其中所述第一方向与所述扫描对象所在平面平行，并且所述第二方向与所述扫描对象所在平面垂直。
S602：经由力施加装置向所述第一扫描对象施加使得所述第一扫描对象与第二扫描对象分开的力。
S603：使得所述力施加装置沿固定轨道移动，其中所述固定轨道与所述扫描对象所在平面相交。
在根据本公开的实施例中，在开始翻页操作的定时处，所述扫描对象被移动到如下的位置处：所述力施加装置向所述第一扫描对象所施加的力的作用位置距离所述第一扫描对象的边缘在预定阈值范围内。
由于在上文已经参考翻页装置100描述了根据本公开实施例的翻页方法，因为在此不再赘述。
本公开实施例还提供了一种扫描装置，该扫描装置包括：
如前所述的翻页装置；
图像获取装置，被配置为对已经翻页的第一扫描对象和/或第二扫描对象成像，并将所获得的图像转换为电子数据。
本公开实施例还提供了一种扫描装置，该扫描装置包括：
至少一个处理器；以及，
与该至少一个处理器通信连接的存储器；其中，
该存储器存储有可被该至少一个处理器执行的指令，该指令被该至少一个处理器执行，以使该至少一个处理器能够执行前述方法实施例中的翻页方法。
下面参考图7，描述根据本公开实施例的扫描装置700的框图。如图7所示，根据本公开实施例的扫描装置700包括翻页装置710和成像装置720。此外，根 据本公开的扫描装置700还包括控制器200，控制器200包括作为控制单元的中央处理单元(CPU)201。
此外，控制器200包括只读存储器(ROM)202、随机存取存储器(RAM)203和硬盘驱动器(HDD)204。此外，控制器200包括接口205。ROM 202、RAM 203、HDD 204和接口205经由总线连接到CPU 201。用于使CPU 201运行的基本程序被存储在ROM 202中。RAM 203是在其中临时存储诸如CPU 201的计算处理结果之类的各种数据的存储设备。HDD 204是在其中存储CPU 201的计算处理的结果、由成像装置720获取的图像数据等的存储设备，并且还用于在其中记录用于使CPU 201执行各种控制的程序。
CPU 201通过根据记录在HDD 204中的程序来控制翻页装置710和成像装置720的操作。
应当理解，本公开的各部分可以用硬件、软件、固件或它们的组合来实现。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
