Description

一种拍照装置、方法及设备 技术领域
本公开涉及摄像技术领域，尤其涉及一种拍照装置、方法及设备。
背景技术
目前，拍照功能已成为智能终端必不可少的功能。人们可以随时随地的记录精彩瞬间。尽管目前的智能终端已可支持1600M像素的摄像头，能获得足够清晰精致画质的图像，但依靠单颗摄像头在拍摄视野开阔的优美风景时，总是受限于视角太小而显得无能为力。一个通用的解决办法是使用广角镜头来弥补视角不足。但广角镜头成像存在前景大，远景小的特点，成品画面变形，与实景相比效果并不理想。另外，广角镜头成本高也是一个值得考虑的因素。
改善智能终端广角摄影效果的措施主要包括采用双摄像头。在这些措施中，通常额外增加广角摄像头，并辅助以软件后期处理。
在一种采用双摄像头方案中，两个摄像头包括一个800万像素135度超广角摄像头和一个1600万像素78度摄像头。两个摄像头不同时工作。普通拍照时使用1600万像素的摄像头，拍风景照时使用超广角摄像头。
在另一种采用双摄像头方案中，两个摄像头包括一个广角摄像头和一个长焦定焦摄像头。广角摄像头的拍摄视野宽，而长焦定焦摄像头可以实现更好的景深效果。通过独特的算法将两张照片拼合，可以让相机模拟出三倍光学变焦效果。
虽然独立使用超广角摄像头可以实现更宽的视角，但是基于广角镜头的成像原理，成像存在前景大，远景小的特点，成品画面变形，与实景相比效果并不理想。
广角镜头和长焦镜头配合使用改善了画面变形的情况，增加 了更多的景深信息，但同时也大大增加了图像软件拼合的复杂程度。因此，这种方式对处理器速度的要求也更高，也增加了成本开销。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述。
根据本公开的一个实施例，提供了一种拍照装置。图1为根据本公开实施例的拍照装置的结构示意图。如图1所示，所述拍照装置包括：第一摄像头101、第二摄像头102、支架103和支架驱动器104，其中，所述支架103被配置成放置第一摄像头和第二摄像头。所述支架103包括一个支撑面和两个对立的侧面形成的壳体。在一个示例性实施例中，所述支撑面与所述两个侧面的上端相连，呈倒U型的形状。所述支架103具有弹性，当所述支架103受到一定的外力作用时会发生形变。同时所述支架103又具有 一定的刚性，当所述第一摄像头和所述第二摄像头放置在所述支架的支撑面且所述支架驱动器未工作时，所述支撑面和载板平行。
所述第一摄像头102和所述第二摄像头103被配置成对拍摄对象进行图像采集。所述第一摄像头102和所述第二摄像头103设置在所述支撑面的外侧，其中，所述支撑面的外侧是所述支撑面位于所述壳体外侧的一个侧面。
在一个示例性实施例中，所述第一摄像头102和所述第二摄像头103可以设置在所述支撑面的外侧的两端，可以是对称设置在所述支撑面的外侧距离两端一定距离的位置，也可以根据实际需要不对称的设置在所述支撑面的外侧。
需要说明的是，在本公开实施例及其他实施例中的“第一”和“第二”仅用于区别各个部件。所述第一摄像头和所述第二摄像头的配置参数可以相同而不存在功能上的差异。
所述支架驱动器104被配置成产生使第一摄像头和第二摄像头发生偏移的驱动力。
在一个示例性实施例中，所述支架驱动器104包括第一电磁铁141、第二电磁铁142、电磁铁驱动电路143和载板144，其中，所述第一电磁铁141在所述壳体中位于所述支架的支撑面的内侧；所述第二电磁铁142放置在载板144上且位于所述第一电磁铁的正下方；所述电磁铁驱动电路143被配置成向所述第一电磁铁和所述第二电磁铁输入电流。
在一个示例性实施例中，所述电磁铁驱动电路143向所述第一电磁铁141和所述第二电磁铁142输入电流后，所述第一电磁铁141和第二电磁铁142产生互斥的磁力。所述互斥的磁力使支架在垂直于双摄像头轴向方向上向外产生小角度弯曲隆起，进而带动所述第一摄像头和所述第二摄像头分别向两侧产生小角度偏转，从而扩大摄像头的可视角度。
所述载板144放置在所述壳体的开口处。
在本公开的其他实施例中，所述拍照装置还可以包括图像处理器105，所述图像处理器被配置成将所述第一摄像头采集的第一 图像和所述第二摄像头采集的第二图像进行拼接，得到第三图像。
本公开实施例提供的拍照装置，包括第一摄像头、第二摄像头、支架和支架驱动器，其中，所述支架包括一个支撑面和两个对立的侧面形成的壳体；所述第一摄像头和所述第二摄像头设置在所述支撑面的外侧，其中，所述支撑面的外侧是所述支撑面位于所述壳体外侧的一个侧面；所述支架驱动器被配置成产生使第一摄像头和第二摄像头发生偏移的驱动力。这样，当需要进行广角摄像时，支架驱动器产生驱动力，使支架在垂直于双摄像头轴向方向上向外产生小角度弯曲隆起，进而带动固定在支架两端的两个摄像头向两侧产生小角度偏转。也就是说，第一摄像头和第二摄像头均向外侧略微倾斜，从而扩大两个摄像头的可视角度。两个摄像头在调整到合适的角度后同时拍照，并将拍摄的图像传送给图像处理器。图像处理器对两张照片重叠的部分合并拼接成为一个广视角图像。根据本公开实施例，使用两个普通的摄像头即可实现广角拍摄，并且没有增加景深信息，降低了图像拼接时图像处理的复杂度。
根据本公开的一个实施例，提供一种可应用于拍照装置拍照方法。图2为根据本公开实施例的拍照方法的流程示意图。如图2所示，所述方法包括以下步骤：
步骤S201，确定第一摄像头的第一倾斜角度和第二摄像头的第二倾斜角度；
步骤S202，控制所述第一摄像头对拍摄对象进行图像采集得到第一图像，并控制第二摄像头对所述拍摄对象进行图像采集得到第二图像；
步骤S203，根据所述第一倾斜角度和所述第二倾斜角度将所述第一图像和所述第二图像进行拼接，得到第三图像；以及
步骤S204，输出所述第三图像。
确定第一摄像头的第一倾斜角度和第二摄像头的第二倾斜角 度的步骤S201可以是通过拍照装置来实现的。所述拍照装置在实际应用中可以是具有拍照功能的智能终端。所述第一摄像头和所述第二摄像头的配置参数有相同而不存在功能上的差异。
在本公开其他实施例中，所述步骤S201进一步包括：
步骤S201a，判断是否接收到用户发出的调节所述第一摄像头的第一控制指令；
步骤S201b，如果接收到所述用户发出的第一控制指令，根据所述第一控制指令和第一初始倾斜角度确定所述第一摄像头的第一倾斜角度；
步骤S201c，判断是否接收到用户发出的调节所述第二摄像头的第二控制指令；以及
步骤S201d，如果接收到所述用户发出的第二控制指令，根据所述第二控制指令和所述第二初始倾斜角度确定所述第二摄像头的第二倾斜角度。
在一个示例性实施中，所述判断是否接收到用户发出的调节所述第一摄像头的第一控制指令的步骤S201a可以包括判断是否接收到用户在预设的操作区域的触摸或滑动操作。如果接收到用户在预设的操作区域的触摸或滑动操作，则判定接收到用户发出的调节所述第一摄像头的第一控制指令；如果没有接收到用户在预设的操作区域的触摸或滑动操作，则判定没有接收到用户发出的调节所述第一摄像头的第一控制指令。
在一个示例性实施中，在所述第一控制指令是用户的滑动操作产生的情况下，则基于滑动的距离和第一初始倾斜角度确定所述第一摄像头的第一倾斜角度。
在实际中，可以预先设定一个滑动距离与倾斜角度的对应关系表，根据滑动距离确定该滑动距离对应的倾斜角度，在将所述倾斜角度与所述第一初始倾斜角度进行累加得到第一倾斜角度。
所述第一初始倾斜角度可以是相机应用启动广角拍摄模式时默认的倾斜角度。
在一个示例性实施中，所述步骤S203进一步包括：
分别提取所述第一图像的第一特征点和所述第二图像的第二特征点；
根据所述第一倾斜角度、所述第二偏转角、所述第一特征点和所述第二特征点，确定所述第一图像和所述第二图像的映射关系矩阵；以及
根据所述映射关系矩阵将所述第一图像和所述第二图像进行拼接，得到所述第三图像。
在一个示例性实施中，所述第三图像为一个广视角图像。
在本公开实施例提供的拍照方法中，首先确定第一摄像头的第一倾斜角度和第二摄像头的第二倾斜角度；然后控制所述第一摄像头对拍摄对象进行图像采集得到第一图像，并控制第二摄像头对所述拍摄对象进行图像采集得到第二图像；再根据所述第一倾斜角度和所述第二倾斜角度将所述第一图像和所述第二图像进行拼接，得到第三图像；输出所述第三图像。这样，通过两个普通的摄像头即可实现广角拍摄，并且仅改变所述第一摄像头和所述第二摄像头的拍摄视角而没有增加景深信息，因而降低了图像拼接时图像处理的复杂度。
根据本公开的一个实施例，还提供一种可应用于拍照装置的拍照方法，其中所述拍照装置在实际应用中可以是具有拍照功能的智能终端。图3为根据本公开实施例的拍照方法的流程示意图。如图3所示，所述方法包括以下步骤：
步骤S301，智能终端基于用户的第一操作，启动相机应用的广角拍摄模式；
在本实施例中，用户可通过多种方式进入广角拍摄模式。例如，用户可以通过相机应用中的控件进入广角拍摄模式，也可以通过终端侧边的触摸操作区域实现，或者还可通过语音以及手势 等控制相机应用进入广角拍摄模式。以上所列举出的广角拍摄模式的触发方式仅仅为示例性的，本领域技术人员利用本公开的技术思想，根据其具体需求所提出的其它广角拍摄模式的触发方式均在本公开的保护范围内。
步骤S302，所述智能终端确定所述第一摄像头的第一初始倾斜角度和所述第二摄像头的第二初始倾斜角度；
这里，所述第一初始倾斜角度和所述第二初始倾斜角度可以是所述智能终端的生产厂商设定的。所述第一初始倾斜角度和所述第二初始倾斜角度可以是相同的，也可以是不同的。
步骤S303，所述智能终端控制所述第一摄像头对拍摄对象进行图像采集得到第四图像，并控制第二摄像头对所述拍摄对象进行图像采集得到第五图像；
步骤S304，所述智能终端根据所述第一初始倾斜角度和所述第二初始倾斜角度将所述第四图像和所述第五图像进行拼接，得到第六图像；
步骤S305，所述智能终端输出所述第六图像；
在一个示例性实施例中，所述第六图像是相机应用启动了广角拍摄模式时，根据两个摄像头的初始倾斜角度拍摄一张初始广视角图像。
步骤S306，所述智能终端判断是否接收到用户发出的调节所述第一摄像头的第一控制指令；
这里，如果用户看到所述第六图像并且对所述第六图像的拍摄视角不满意时，可以自行调节广角拍摄的拍摄视角。
如果所述智能终端接收到用户发出的调节所述第一摄像头的第一控制指令，则所述方法进入步骤S307。如果所述智能终端没有接收到所述用户发出的调节所述第一摄像头的第一控制指令，则所述方法进入步骤S308。
步骤S307，如果接收到所述用户发出的第一控制指令，所述 智能终端根据所述第一控制指令和第一初始倾斜角度确定所述第一摄像头的第一倾斜角度；
步骤S308，所述智能终端判断是否接收到用户发出的调节所述第二摄像头的第二控制指令；
这里，如果所述智能终端接收到用户发出的调节所述第二摄像头的第二控制指令，则所述方法进入步骤S309。如果所述智能终端没有接收到所述用户发出的调节所述第二摄像头的第二控制指令，则结束流程。
步骤S309，如果接收到所述用户发出的第二控制指令，所述智能终端根据所述第二控制指令和第二初始倾斜角度确定所述第二摄像头的第二倾斜角度。
这里需要说明的是，在本公开实施例中所述第一摄像头和所述第二摄像头的倾斜角度可以单独进行调节；在本公开其他实施例中所述第一摄像头和所述第二摄像头的倾斜角度可以通过一个调节指令进行调节。
步骤S310，所述智能终端控制所述第一摄像头对拍摄对象进行图像采集得到第一图像，并控制第二摄像头对所述拍摄对象进行图像采集得到第二图像；
步骤S311，所述智能终端根据所述第一倾斜角度和所述第二倾斜角度将所述第一图像和所述第二图像进行拼接，得到第三图像；
步骤S312，所述智能终端输出所述第三图像。
在本公开实施例提供的拍照方法中，首先确定第一摄像头的第一倾斜角度和第二摄像头的第二倾斜角度；然后控制所述第一摄像头对拍摄对象进行图像采集得到第一图像，并控制第二摄像头对所述拍摄对象进行图像采集得到第二图像；再根据所述第一倾斜角度和所述第二倾斜角度将所述第一图像和所述第二图像进行拼接，得到第三图像；输出所述第三图像。这样，通过两个普通的摄像头即可实现广角拍摄，并且仅改变所述第一摄像头和所 述第二摄像头的拍摄视角而没有增加景深信息，因而降低了图像拼接时图像处理的复杂度。
根据本公开的一个实施例，还提供一种拍照装置。图4-1为根据本公开实施例的拍照装置的结构示意图。如图4-1所示，所述拍照装置包括第一摄像头411、第二摄像头412、形变支架413、支架驱动装置414、图像处理器415。所述第一摄像头411和所述第二摄像头412被配置成同时拍摄摄影对象的图像。所述形变支架413被配置成扩大摄像主体的可视角。所述驱动装置414向所述形变支架施加力以使其产生形变。所述图像处理器415被配置成将图像进行后期处理合成。
在图4-1中，所述第一摄像头和所述第二摄像头水平固定在形变支架的两端。当需要进行广角摄像时，支架驱动装置产生驱动力，使形变支架在垂直于双摄像头的轴向方向上向外产生小角度弯曲隆起，进而带动固定在支架两端的第一摄像头和第二摄像头向两侧产生小角度偏转。也就是说，第一摄像头和第二摄像头均向外侧略微倾斜，从而扩大两个摄像头的可视角度。两个摄像头在调整到合适的角度后同时拍照，并将拍摄的图像传送给图像处理器，图像处理器对两张照片重叠的部分合并拼接，最后合成为一个广视角图像。
根据本公开的一个实施例，提供一种广角拍摄的磁控实现方法。该方法可应用于如图4-2所示的拍照装置。如图4-2所示，所述拍照装置包括：第一摄像头421、第二摄像头422、形变支架423、支架驱动装置424和图像处理器425。
所述第一摄像头421和所述第二摄像头422不存在功能上的差异。
所述形变支架423除了具有一定的弹性外，还需具备必要的刚性。当两个摄像头分别安装在支架的两端并且支架被安置于载 板上时，摄像头的安装平面能与载板平面保持平行。
所述支架驱动装置424由第一电磁铁4241、第二电磁铁4242以及电磁铁驱动电路4243构成。第一电磁铁4241安装在形变支架的中心位置，与第一和第二摄像头保持等距。第二电磁铁4242安装在载板上并位于第一电磁铁相对的正下方。通过控制两个电磁铁线圈的绕向，确保第一电磁铁与第二电磁铁在通电后产生的磁极同向相对。
当移动终端启动广角拍摄模式时，电磁铁驱动电路分别向第一电磁铁和第二电磁铁输出电流，使第一电磁铁与第二电磁铁间产生互斥磁力。固定在形变支架上的第一电磁铁在互斥磁力的作用下，带动形变支架向外产生小角度变形，进而使固定在弹性支架两端的第一摄像头和第二摄像头向两侧产生小角度偏转。也就是说，第一摄像头和第二摄像头均向外侧略微倾斜，从而实现可视角度的扩大。电磁铁驱动电路通过调节输出电流的大小来控制支架形变，进而控制摄像头倾斜角度的大小，实现摄像头可视角度的可调性。两个待双摄像头在调整到合适的角度后进行同时拍照，可获得两张部分角度重叠的图像。图像处理器根据电磁铁驱动电路的输出电流计算出摄像头的倾斜角度，并将两张照片中角度重叠的部分合并拼接成为一个广视角图像。
如图4-3所示，在所述第一电磁铁和所述第二电磁铁的作用下，所述形变支架向上产生高度为h的弯曲形变，使得第一摄像头和第二摄像头的底面与载板平面均形成θ夹角。支架的总长度为2L，第一摄像头和第二摄像头到形变支架中心的距离均为L。对于小角度形变，θ可近似大致上等于h和L为直角边构成的直角三角形产生的夹角替代。在这种情况下，因此θ≈arctg(h/L)。第一摄像头和、第二摄像头在支架的形变作用下，分别向远离支架中心的方向偏转θ角，进而摄像组的可视角可向外扩张2倍θ角。针对同等距离的景物，拍摄者可看到的成像范围将从原来的M，扩展到M’。
需要说明的是，由于本公开实例采用的是一种利用电磁效应获得力学变形的实现方法，在使用中会产生较强的电磁场。为避免对系统中的其他电子器件产生电磁干扰，如有必要可以在装置外部采取必要的电磁屏蔽措施，如增设屏蔽罩，来减少对外的电磁辐射。
本公开包括但不限于使用固定斜面支架来使固定于其上的双摄像头模组与载板平面产生固定交角来扩大模组的可视角。作为选择，可以使用机械传动等方法代替本公开实例中的电磁铁驱动方式使支架变形而获得可调的广视角效果。
根据本公开的一个实施例，提供一种拍照设备。图5为根据本公开实施例的拍照设备的结构示意图。如图5所示，所述拍照设备500包括：第一确定模块501、第一控制模块502、第一拼接模块503和第一输出模块504。
所述第一确定模块501被配置成确定第一摄像头的第一倾斜角度和第二摄像头的第二倾斜角度。
所述第一确定模块501进一步包括：第一判断单元，被配置成判断是否接收到用户发出的调节所述第一摄像头的第一控制指令；第一确定单元，被配置成如果接收到所述用户发出的第一控制指令，根据所述第一控制指令和所述第一倾斜角度确定所述第一摄像头的第一倾斜角度；第二判断单元，被配置成判断是否接收到用户发出的调节所述第二摄像头的第二控制指令；第二确定单元，被配置成如果接收到所述用户发出的第二控制指令，根据所述第二控制指令和所述第二初始倾斜角度确定所述第二摄像头的第二倾斜角度。所述第一控制模块502，被配置成控制所述第一摄像头对拍摄对象进行图像采集得到第一图像，并控制第二摄像头对所述拍摄对象进行图像采集得到第二图像；以及所述第一拼接模块503，被配置成根据所述第一倾斜角度和所述第二倾斜角度将所述第一图像和所述第二图像进行拼接，得到第三图像。
所述第一拼接模块503进一步包括：提取单元，被配置成分别提取所述第一图像的第一特征点和所述第二图像的第二特征点；第三确定单元，被配置成根据所述第一倾斜角度、所述第二偏转角、所述第一特征点和所述第二特征点，确定所述第一图像和所述第二图像的映射关系矩阵；以及拼接单元，被配置成根据所述映射关系矩阵将所述第一图像和所述第二图像进行拼接，得到所述第三图像。
所述第一输出模块504被配置成输出所述第三图像。
在本公开的一个示例性实施中，所述拍照装置还包括：启动模块，被配置成基于用户的第一操作，启动相机应用的广角拍摄模式；第二确定模块，被配置成确定所述第一摄像头的第一初始倾斜角度和所述第二摄像头的第二初始倾斜角度；第二控制模块，被配置成控制所述第一摄像头对拍摄对象进行图像采集得到第四图像，并控制第二摄像头对所述拍摄对象进行图像采集得到第五图像；第二拼接模块，被配置成根据所述第一初始倾斜角度和所述第二初始倾斜角度将所述第四图像和所述第五图像进行拼接，得到第六图像；以及第二输出模块，被配置成输出所述第六图像。
