具体实施方式
以下结合附图对本发明进行详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。
如图1所示，本发明实施例提供一种拍摄装置，其中，图1(a)为其正面结构示意图，图1(b)为其背面结构示意图，包括：
本体10，本体10上分别设置有第一摄像头21和外设接口30；
外设接口30通过柔性电缆可拆卸地与第二摄像头21电连接；其中，第一摄像头21和第二摄像头22位于所述本体的同一侧；第二摄像头22上设置有第一滑动部221，本体10上设置有与第一滑动部221相配合的第二滑动部102，第二摄像头22通过第一滑动部221和第二滑动部102在本体10上滑动，以调整自身与第一摄像头21之间的距离。第一摄像头21与第二摄像头22同时对拍摄对象拍摄以形成立体影像。
本发明实施例提供的拍摄装置，通过外设接口30可以连接第二摄像头22，该第二摄像头22可以通过在本体10上滑动来调整自身与第一摄像头21之间的距离，这样，就能够适应远近不同的拍摄对象，使两个摄像头与该拍摄对象之间形成合适的角度，当两个摄像头同时拍摄时，即可形成立体感较强的影像。
为了便于确定拍摄对象距离摄像头的距离，可选的，本体10上还可以设置有触控显示屏40，第一摄像头21和第二摄像头22分别可以将拍摄对象在触控显示屏40成像，以确定拍摄对象与本体10之间的距离。
为了确定第二摄像头22在本体10上滑动到哪个位置，从而度量出第二摄像头22与第一摄像头21之间的距离，进一步的，在本发明的一个实施例中，触控显示屏40上还可设置有定位部，在滑动过程中，第二摄像头22可以通过设置在第二摄像头22上的触控感应部222与触控显示屏40相接触并通过定位部定位。其中，触控感应部222可以由任何能够对电容屏进行有效触控的材料制成。当第二摄像头22在本体10上滑动时，触控感应部222也在触控显示屏40上做相应滑动，定位部可以触控跟踪感应部222的滑动轨迹从而确定第二摄像头22的位置。可选的，定位部可以是分布在触控显示屏40上的标尺、栅格、定位标点等多种可以作为距离度量的标志，定位部既可以是由程序生成的虚拟标志，也可以是设置在触控显示屏40上的物理标志，只要能够确定触控感应部222的位置即可。本发明的实施例对此不作限定。
进一步的，在本发明的一个实施例中，本体10内部还可设置有处理部，处理部 可以根据定位部指示的第二摄像头22与第一摄像头21之间的距离、第二摄像头22和第一摄像头21各自聚焦拍摄对象的焦距，确定拍摄对象与本体10之间的距离。
在确定了拍摄对象与本体10之间的距离后，处理部还可用于根据拍摄对象与本体10之间的距离调整第一摄像头21与第二摄像头22之间的距离。可选的，在第二摄像头22滑动过程中，可以通过定位部获知第二摄像头22的位置并反馈给处理部，形成对第二摄像头22的闭环控制，从而大大提高了移动控制精度。
举例而言，如图2所示，在双摄像头系统中，两个摄像头可以同时对拍摄对象进行聚焦，如果已知摄像头之间的初始距离A1C1以及摄像头聚焦拍摄目标时的焦距F，双摄像头系统就能计算出拍摄对象B1与摄像头之间的距离L1。获知L1后，再根据L1与两摄像头的目标距离L2之间的对应关系调整摄像头1和摄像头2之间的距离。当A1、B1、C1的位置关系满足预设角度时，即可获得一个比较好的立体拍摄效果。其中，L1和L2之间的对应关系可以是某种函数关系，也可以是建立的映射表，本发明的实施例对此不做限定。
进一步的，处理部对于第二摄像头22的移动控制需要通过驱动实现。可选的，第二摄像头22上可以设置有驱动部，驱动部通过外设接口30与本体10电连接，该驱动部可以用于根据处理部的控制驱动第二摄像头22沿第二滑动部102滑动，以调整第二摄像头22与第一摄像头21之间的距离。可选的，该驱动部可以是马达等动力部件。
具体的，第一滑动部221与第二滑动部102可以包括各种相互配合的滑动装置，只要能使第二摄像头22沿本体10表面滑动即可，本发明的实施例对此不做限定。例如，在本发明的一个实施例中，第一滑动部221包括设置在第二摄像头22上的滑块，第二滑动部102可包括设置在本体10上的滑轨。
如图3所示，对于不同终端，第一摄像头21在本体10上的位置也可能有所不同，例如有的摄像头位于靠近终端一侧的中间位置，有的摄像头则位于终端的一个角落，如左上角或右上角等。为了便于适应各种位置的第一摄像头21，在本发明的一个实施例中，本体10上的滑轨可以包括两组，其中一组可以在另一组上滑动。具体而言，所述滑轨包括两条平行设置的第一滑轨1031，以及横跨在两条第一滑轨1031上的第二滑轨1032；第二摄像头22可滑动地设置在第二滑轨1032上，第二滑轨1032可滑动地设置在第一滑轨1031上。
下面通过具体实施例对本发明提供的拍摄装置进行详细说明。如图4所示，在图4(a)中，手机进入立体拍照模式，外置的第二摄像头22可调整到起始基准位置，以图4中空心黑圆表示(例如，根据手机背后的标尺，确定该基准位置为第二摄像头22与手机内置的第一摄像头21距离60mm)。手机聚焦拍摄目标后，手机即计算出该目标的立体拍摄双摄像头最佳位置在实心黑圆位置，再将第二摄像头22调整到拍摄该目标的最佳位置，移动后第二摄像头22的位置可如图4(b)所示。
本实施例中，第二摄像头22上设置有触控感应部222，该触控感应部222可以由柔性导电材料制成，触控感应部222可随第二摄像头22在触控显示屏40上滑动，触控显示屏40上的定位部能侦测到触控感应部222的当前位置。第二摄像头22上的驱动部可以按照处理部的指令调整第二摄像头22的位置，触控感应部222又能将第二摄像头22的当前位置通过触控显示屏40上的定位部及时反馈给处理部，形成闭环系统。
需要说明的是，上述实施例中第一摄像头21是移动终端的后置摄像头，为了形成立体摄像，第二摄像头22需要与第二摄像头21同侧，因此第二摄像头22也设置在移动终端背面。相应的，本体10上的第二滑动部102也设置在本体10的背面，即设置在与触控显示屏40相对的一面。第二摄像头22的触控感应部222可以从第二摄像头22上延伸出，绕到本体10的触控显示屏40上，从而通过触控显示屏40上的定位部进行定位。但本发明不限于此，在本发明的其他实施例中，第一摄像头21和第二摄像头22也可以位于移动终端的前侧，即二者都可以是前置摄像头。
相应的，如图5所示，本发明的实施例还提供一种前述实施例提供的拍摄装置的工作方法，包括：
S11，确定所述第一摄像头和所述第二摄像头聚焦的拍摄对象与所述拍摄装置之间的拍摄距离；
S12，根据所述拍摄距离确定所述第一摄像头与所述第二摄像头之间的目标距离；
S13，调整所述第二摄像头的位置，以使所述第二摄像头与所述第一摄像头之间的距离等于所述目标距离；
S14，控制所述第一摄像头与所述第二摄像头同时对所述拍摄对象成像。
本发明实施例提供的拍摄装置的工作方法，能够确定拍摄对象与拍摄装置之间的拍摄距离，然后根据拍摄距离确定第一摄像头和第二摄像头之间的目标距离，并对第 二摄像头的位置进行相应的调整。这样，当第一摄像头与第二摄像头同时对拍摄对象拍摄成像时，即可合成立体感强的影像，从而显著提升了拍摄装置的立体拍摄性能。
具体而言，如图6所示，在本发明的一个实施例中，用户用智能手机拍摄立体照片或视频时，启动手机3D拍摄应用，进入拍摄状态，其步骤包括：
S21、安装外置的第二摄像头，手机与第二摄像头系统建立连接；
S22、手机启动立体拍摄模式，将外置摄像头调整到基准位置；
S23、手机按用户意图，聚焦拍摄对象；
S24、手机计算拍摄目标的距离及双摄像头之间的最佳拍摄距离；
S25、手机调整第二摄像头到最佳拍摄位置；
S26、手机按用户意图，双摄像头同时拍摄目标(拍照或录像)。
可选的，调整位置也可手动进行。即用户首先将第二摄像头调整到基准位置，手机聚焦拍摄对象后，在触控显示屏上显示第二摄像头调整的目标位置，用户将第二摄像头手动调整到该位置进行拍摄。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本发明各个实施例所述的方法。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
