【具体实施方式】
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
用于拍摄VR图像的移动终端实施例
首先需要说明的是，本发明实施例中的移动终端可以为手机、平板电脑或笔记本电脑等便携式电子设备。
请参阅图1，图1是本发明用于拍摄VR图像的移动终端一优选实施例的背面结构示意简图，该移动终端100包括两个摄像头（110、120），两个摄像头（110、120）分别镶嵌设于移动终端外壳130的表面，在本实施例中的，两个摄像头（110、120）中心位置的连线102平行于移动终端外壳130的顶边。当然，在其他实施例中，两个摄像头（110、120）中心位置的连线102还可以平行于移动终端外壳130的侧边。在本领域技术人员的理解范围内，此处就不再用示意图进行说明。
优选地，两个摄像头（110、120）的物理特性相同，其中，摄像头的物理特性包括最大光圈、焦距、视角、分辨率等。摄像头(Camera)作为一种视频输入设备，在过去被广泛的运用于手机拍照、视频会议，远程医疗及实时监控等方面。近年以来，随着互联网技术的发展、网络速度的不断提高、再加上感光成像器件技术的成熟并大量用于摄像头的制造上，这使得它的价格降到普通人可以承受的水平。
摄像头分为数字摄像头和模拟摄像头两大类，本发明中可以为两者中任意一种。模拟摄像头可以将视频采集设备产生的模拟视频信号转换成数字信号，进而将其储存在移动终端100的存储器（图中未示）里；模拟摄像头捕捉到的视频信号必须经过特定的视频捕捉卡将模拟信号转换成数字模式，并加以压缩后才可以转换到移动终端100上运用；数字摄像头则可以直接捕捉影像，然后传到移动终端100里。现在电子产品市场上的摄像头基本以数字摄像头为主。 摄像头的工作原理为：景物通过镜头(LENS)生成的光学图像投射到图像传感器表面上，然后转为电信号，经过A/D(模数转换)转换后变为数字图像信号，再送到数字信号处理器中加工处理，再通过传输线传输到移动终端100的处理器进行处理，通过显示屏就可以看到图像了。
从摄像头的工作原理就可以列出摄像头的主要结构和组件：主控芯片、感光芯片、镜头以及供电电源等。摄像头内部需要两种工作电压：3.3V和2.5V，因此好的摄像头内部电源也是保证摄像头稳定工作的一个因素。
1、镜头(LENS) 镜头的组成是透镜结构，由几片透镜组成，一般有塑胶透镜(plastic)或玻璃透镜(glass)。通常摄像头用的镜头构造有：1P、2P、1G1P、1G2P、2G2P、4G等。 2、感光芯片(SENSOR) 是组成数码摄像头的重要组成部分，根据元件不同分为： CCD（Charge Coupled Device，电荷耦合元件）应用在摄影摄像方面的高端技术元件。 CMOS（Complementary Metal-Oxide Semiconductor，金属氧化物半导体元件）应用于较低影像品质的产品中。 CCD的优点是灵敏度高，噪音小，信噪比大。但是生产工艺复杂、成本高、功耗高。 CMOS的优点是集成度高、功耗低(不到CCD的1/3)、成本低。但是噪音比较大、灵敏度较低、对光源要求高。在相同像素下CCD的成像往往通透性、明锐度都很好，色彩还原、曝光可以保证基本准确。而CMOS的产品往往通透性一般，对实物的色彩还原能力偏弱，曝光也都不太好。本发明实施例中优选为CCD感光芯片的摄像头。
下面对摄像头主要参数介绍如下。1.最大光圈：最大光圈的真正价值表现在监控摄像头提高弱光情况下的进光量，从而达到最佳曝光组合。最大光圈大的镜头能带来较快的快门速度；2.焦距：焦距实际上就是视角问题，焦距不同视角也不同。
优选地，本发明实施例中的两个摄像头（110、120）被移动终端100的处理器以同步的方式进行控制，即：同步控制两个摄像头的开始及停止拍摄，这样才能保证拍出满足同步性要求的VR图像（保证播放时、左右眼看到的画面同步）。
该移动终端100内部设有位置传感器（图中未示），位置传感器用于检测两个摄像头的中心位置连线102是否处于预设的可拍摄VR图像倾角范围内，该位置传感器可以为外置水平仪140或者内置的陀螺仪（图中未示）的结构。
优选地，在拍摄过程中，两个摄像头（110、120）的中心位置连线102预设的可拍摄VR图像倾角范围为：与水平线之间夹角±10度。且两个摄像头（110、120）的中心位置距离D为3-15cm。进一步优选范围D为5.5-7.5cm，两个摄像头（110、120）的中心位置距离D最佳值为6.5cm。
进一步地，该移动终端100还包括指示灯150，指示灯150镶嵌设于移动终端的外壳130的表面，用于指示两个摄像头（110、120）的中心位置连线102是否处于预设的可拍摄VR图像倾角范围内。
譬如，当位置传感器检测到两个摄像头（110、120）的中心位置连线102处于预设的可拍摄VR图像倾角范围内时，指示灯150发出绿色的光；而当位置传感器检测到两个摄像头（110、120）的中心位置连线102不在预设的可拍摄VR图像倾角范围内时，则指示灯150发出红色的光，同时移动终端100可以发出“滴滴滴”的提示音，以提示当前姿态无法拍摄满足要求的VR图像，进而使用者将移动终端100摆正，使两个摄像头（110、120）的中心位置连线102靠近水平方向。
两个摄像头（110、120）拍摄的图像以分屏的方式显示在移动终端100的显示屏上。左侧摄像头110拍摄的画面在显示屏的左侧显示，右侧摄像头110拍摄的画面在对应显示在显示屏的右侧，在利用VR播放设备观看时，两侧画面分别对应人的左右两只眼睛。
进一步地，该移动终端100上还设有图像传输接口160，该图像传输接口160嵌设于移动终端100一侧的外壳边沿，用于与外置摄像装置信号传输连接，关于外置摄像装置的具体结构特征将在后续实施例中详细描述。
相对于现有技术，本发明提供的用于拍摄VR图像的移动终端，通过在移动终端上设置两个摄像头，并保证以下条件：1、两个摄像头中心位置的连线基本处于水平位置；2、两个摄像头的物理特性相同；3、两个摄像头被同步驱动控制；以及4、两个摄像头之间的距离与人眼距离相同。满足以上条件就可以利用移动终端拍摄出VR图像。其中，移动终端可以为人们常用的手机、平板电脑的便携式电子设备，可以大大方便VR图像的拍摄，且操作简单、成本低廉，有利于VR产业的推广。

摄像单元（210、220）包括摄像头201以及摄像头固定座202，摄像头固定座202用于固定摄像头201并与滑块243对应固定连接。两个摄像头201的物理特性相同，其中，摄像头的物理特性包括最大光圈、焦距、视角、分辨率等。
优选地，摄像头固定座202的外侧边沿设有卡位凸起2021，支撑框体241的侧边设有与卡位凸起2021配合的多个卡接槽2411，卡位凸起2021与卡接槽2411配合实现将摄像头固定座202卡接定位到支撑框体241的不同位置，进而实现两个摄像头距离H的调节。
信号传输连接端子230与移动终端100上的图像传输接口160连接，用于将摄像单元拍摄的VR图像传输到移动终端100，并传输移动终端100发出对拍摄装置两个摄像单元（210、220）的同步驱动控制信号。
拍摄装置200还包括位置传感组件250，该位置传感组件250与支撑框体241的边沿固定连接，位置传感组件250用于检测两个摄像单元（210、220）的中心位置连线是否处于预设的可拍摄VR图像倾角范围内，位置传感组件250的检测信号通过信号传输连接端子230传输到移动终端100。

进一步优选地，该位置传感组件250进一步包括指示灯252，指示灯252镶嵌设于固定外壳251的外表面，用于指示两个摄像单元（210、220）的中心位置连线222是否处于预设的可拍摄VR图像倾角范围内。
譬如，当位置传感组件250检测到两个摄像单元（210、220）的中心位置连线222处于预设的可拍摄VR图像倾角范围内时，指示灯252发出绿色的光；而当位置传感组件250检测到两个摄像单元（210、220）的中心位置连线222不在预设的可拍摄VR图像倾角范围内时，则指示灯252发出红色的光，同时移动终端100可以发出“滴滴滴”的提示音，以提示当前姿态无法拍摄满足要求的VR图像，进而使用者将移动终端100摆正，使两个摄像单元（210、220）的中心位置连线222靠近水平方向。进而满足拍摄要求。
优选地，在拍摄过程中，两个摄像单元（210、220）的中心位置连线222预设的可拍摄VR图像倾角范围为：与水平线之间夹角±10度。且两个摄像单元（210、220）的中心位置距离H为3-15cm。进一步优选范围H为5.5-7.5cm，两个摄像单元（210、220）的中心位置距离H 最佳值为6.5cm。
该实施例提供的拍摄装置，通过设置滑动组件结构，使两个摄像单元之间实现滑动连接，进而达到调节两个摄像单元之间距离的目的；另外设置有水平传感器，保证拍摄过程中两个摄像单元的中心位置连线处于预设的可拍摄VR图像倾角范围内（与水平线之间夹角±10度）；该种拍摄装置结构简单，成本低，使用过程中可以佩戴在头上或者夹持在移动终端上等位置，通过信号传输连接端子与移动终端连接后，既可以实现VR图像的拍摄，在很大程度上有利于VR产业的推广与普及。

请一并参阅图3和图4，图3是拍摄装置的两个摄像单元另一位置状态的正面结构示意图，图4是图2实施例中VR图像的拍摄装置的背面结构示意图。
该滑动组件240包括支撑框体241、以及设于支撑框体241内部并与支撑框体241内侧壁固定连接的导轨242，导轨242上设有配合滑动连接的两个滑块243，每一滑块243分别对应与一摄像单元（210、220）连接。
摄像单元（210、220）包括摄像头201以及摄像头固定座202，摄像头固定座202用于固定摄像头201并与滑块243对应固定连接。两个摄像头201的物理特性相同，其中，摄像头的物理特性包括最大光圈、焦距、视角、分辨率等。
优选地，摄像头固定座202的外侧边沿设有卡位凸起2021，支撑框体241的侧边设有与卡位凸起2021配合的多个卡接槽2411，卡位凸起2021与卡接槽2411配合实现将摄像头固定座202卡接定位到支撑框体241的不同位置，进而实现两个摄像头距离H的调节。
信号传输连接端子230与移动终端100上的图像传输接口160连接，用于将摄像单元拍摄的VR图像传输到移动终端100，并传输移动终端100发出对拍摄装置两个摄像单元（210、220）的同步驱动控制信号。
拍摄装置200还包括位置传感组件250，该位置传感组件250与支撑框体241的边沿固定连接，位置传感组件250用于检测两个摄像单元（210、220）的中心位置连线是否处于预设的可拍摄VR图像倾角范围内，位置传感组件250的检测信号通过信号传输连接端子230传输到移动终端100。
该位置传感组件250包括固定外壳251以及设于固定外壳251内部的位置传感器（图中未示），固定外壳251与支撑框体241的边沿固定连接。该位置传感器可以为水平仪或者陀螺仪等，在本领域技术人员的理解范围内，此处不再一一列举。
进一步优选地，该位置传感组件250进一步包括指示灯252，指示灯252镶嵌设于固定外壳251的外表面，用于指示两个摄像单元（210、220）的中心位置连线222是否处于预设的可拍摄VR图像倾角范围内。
譬如，当位置传感组件250检测到两个摄像单元（210、220）的中心位置连线222处于预设的可拍摄VR图像倾角范围内时，指示灯252发出绿色的光；而当位置传感组件250检测到两个摄像单元（210、220）的中心位置连线222不在预设的可拍摄VR图像倾角范围内时，则指示灯252发出红色的光，同时移动终端100可以发出“滴滴滴”的提示音，以提示当前姿态无法拍摄满足要求的VR图像，进而使用者将移动终端100摆正，使两个摄像单元（210、220）的中心位置连线222靠近水平方向。进而满足拍摄要求。
优选地，在拍摄过程中，两个摄像单元（210、220）的中心位置连线222预设的可拍摄VR图像倾角范围为：与水平线之间夹角±10度。且两个摄像单元（210、220）的中心位置距离H为3-15cm。进一步优选范围H为5.5-7.5cm，两个摄像单元（210、220）的中心位置距离H 最佳值为6.5cm。
该拍摄装置，通过设置滑动组件结构，使两个摄像单元之间实现滑动连接，进而达到调节两个摄像单元之间距离的目的；另外设置有水平传感器，保证拍摄过程中两个摄像单元的中心位置连线处于预设的可拍摄VR图像倾角范围内（与水平线之间夹角±10度）；该种拍摄装置结构简单，成本低，使用过程中可以佩戴在头上或者夹持在移动终端上等位置，通过信号传输连接端子与移动终端连接后，既可以实现VR图像的拍摄，在很大程度上有利于VR产业的推广与普及。
本发明实施例提供的VR图像拍摄系统，通过在移动终端上连接外置双摄像头结构，可以在移动终端自身摄像头以及外置摄像头中选择使用其中的一组用作拍摄VR图像来使用，插接即可实现配合连接，通过移动终端即可控制外接摄像头，其结构简单，操作方便。
以上所述仅为本发明的部分实施例，并非因此限制本发明的保护范围，凡是利用本发明说明书及附图内容所作的等效装置或等效流程变换，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。
