 本发明的实施方式
下面结合实施例对本申请进行详细说明。其中相同的零部件用相同的附图标记表示。需要说明的是，下面描述中使用的词语“前”、“后”、“左”、“右”、“上”和“下”指的是附图中的方向，词语“内”和“外”分别指的是朝向或远离特定部件几何中心的方向。
图1为本申请实施例提供的立体摄像机的主视图，图2为图1在竖直方向上旋转一定角度后的侧视图，图3为图1的俯视图。从图1至图3可以看出，本申请实施例提供了一种立体摄像机1，包括多个摄像头11、齿轮组12、用于固定多个齿轮121的多个连接杆13。
所述齿轮组12包括多个齿轮121，多个所述齿轮121相互啮合，每个齿轮121的端面上固定有所述摄像头11，多个所述连接杆13与多个所述齿轮121一一对应地连接；其中，所述连接杆131的端部固定连接在所述齿轮121上背向所述摄像头11的端面上，并且相互连接的所述连接杆13和所述齿轮121共轴设置。
请同时参照图1至图3，本申请实施例提供的立体摄像机1，其中包括的多个摄像头11用于获取图像，将多个所述摄像头11固定在齿轮组12中相互啮合的齿轮121上，通过齿轮121之间的相互转动，可以使与齿轮121固定的摄像头11随之发生转动，使摄像头11的摄像角度在水平方向可调。本申请实施例提供的立体摄像机1中还包括连接杆13，通过将连接杆13的另一端可拆卸地固定在其他设备上，可使与连接杆13固定连接的齿轮121的位置得以固定，进而保证了齿轮组12中的多个齿轮121的相对位置的固定。同时，为了防止连接杆13与齿轮121连接后，齿轮121发生倾斜，本申请实施例提供的立体摄像机1将相互连接的连接杆13与齿轮121共轴设置。此外，还可以通过设置连接杆13的另一端固定时在竖直方向上具有一定的倾角，使所述立体摄像机1的摄像头11在竖直方向上具有一定的倾角，通过改变所述连接杆13的另一端的倾斜角度，从而达到使所述立体摄像机1的摄像角度在竖直方向上可调的效果。本申请实施例提供的立体摄像机1，可以灵活调节摄像头11之间的夹角和摄像头11在水平、竖直方向上的视角，增加了所述立体摄像机1与其他设备的关联性。
在上述实施例的基础上，所述摄像头11的数量为两个。将所述立体摄像头11的数量设置为两个是目前较为常见立体摄像机的镜头设置方式，在满足拍摄要求的前提下，便于与其他设备相关联，同时可简化所述齿轮组12的设置，直接将所述齿轮121的数量设置为两个即可，降低了生产成本。在实际拍摄过程中，可根据拍摄要求的不同对齿轮121进行旋转，进而调节与所述齿轮121固定连接的摄像头11的视角。本技术领域人员可以理解的是，所述摄像头11的数量并不仅限于两个，可以根据实际拍摄的要求进行灵活设置。
优选的是，本申请实施例提供的立体摄像机1还包括横向连接轴14，多个所述连接杆13均可转动地连接在所述横向连接轴14上，每个所述连接杆13与所述横向连接轴14之间的相对转动轴线与所述连接杆13的中心轴线重合。本申请实施例通过设置一个横向连接轴14达到固定多个连接杆13的效果，使其结构紧凑化和集成化，同时设置为每个所述连接杆13与所述横向连接轴14之间的相对转动轴线与所述连接杆13的中心轴线重合，以保证多个所述连接杆13平行设置，达到使连接杆13平稳固定在横向连接轴14上的目的。同时将多个连接杆13同时固定在一个横向连接轴14上，便于将与连接杆13相固定的齿轮121的相对位置固定，在移动立体摄像机1时，所述齿轮组12中的齿轮121不会发生分离的现象，保证所述齿轮组12的稳固。
进一步地，所述横向连接轴14上设置有多个安装孔(未示出)，多个所述连接杆13一一对应地穿设在多个所述安装孔中，并且每个所述安装孔的内表面和与之相连接的连接杆13的每个所述连接杆13的外表面间隙配合。由于固定有摄像头11的齿轮组12在拍摄图像时，需要根据具体图像的方位或者具体图像的大小，旋转齿轮121以调整所述摄像头11的角度以及相邻摄像头的夹角，由于所述连接杆13与所述齿轮121为固定连接，所述齿轮121发生转动时，所述连接杆13亦随之发生转动，为了保证与所述连接杆13的另一端连接的横向连接轴14在齿轮121旋转时，不会随之发生转动，多个所述连接杆13一一对应地穿设在多个所述安装孔中后，将横向连接轴14上与所述连接杆13连接的安装孔的内表面设置为和与之相连接的连接杆13的外表面间隙配合。在齿轮121发生转动时，齿轮121仅带动连接杆13转动，而不会对横向连接轴14的位置产生影响。
进一步地，本申请实施例提供的立体摄像机1还包括支杆15，所述支杆15与所述横向连接轴14可转动地连接，所述支杆15与所述横向连接轴14之间的相对转动轴线与所述横向连接轴14的中心轴线重合。将所述支杆15设置为与所述横向连接轴14旋转连接，可进一步增加所述摄像头11在竖直方向角度调节的灵活性，直接通过所述支杆15与所述横向连接轴14之间在竖直方向上的角度，便可以调整所述摄像头11在竖直方向上的拍摄角度，具有调节快捷灵巧，调节角度范围广的优点。
在上述实施例的基础上，所述横向连接轴14上延伸出两个连接片(未示出)，所述两个连接片相对设置，所述两个连接片上分别开设有第一连接孔(未示出)和第二连接孔(未示出)，所述第一连接孔和所述第二连接孔轴向对齐，所述支杆15设置在两个连接片之间，所述支杆15在与所述第一连接孔和所述第二连接孔轴向对齐的方向上开设有第三连接孔(未示出)。螺栓依次穿过所述第一连接孔、第三连接孔和第二连接孔后紧固。上述连接方式在需要调节角度时，可将螺栓上的紧固螺母拆下，根据摄像头11所需的角度重新调整所述支杆15与所述横向连接轴14之间的角度，调节好后，重新将螺栓上的螺母安装在螺栓上，拧紧螺母，保证支杆15不会发生转动即可。采用螺接的方式是一种较为简单易行，低成本且便于调节角度的方式。本技术领域人员可以理解的是，所述支杆15和所述横向连接轴14之间的连接方式并不仅限于此，能保证所述横向连接轴14和所述支杆15之间的角度灵活可调，同时在角度调节好后，可以稳固定位即可。
优选的是，所述支杆15的外表面与两个所述连接片的内表面间隙配合。经所述支杆15的外表面设置为与两个所述连接片内表面之间的间隔间隙配合，既可以保证在拆卸过程中，支杆15可以灵活地从所述横向连接轴14的两个连接片之间的间隙中抽出，同时保证了在支杆15与两个连接片紧固的过程中，所述支杆15的外表面在螺母轻微的挤压下，便可以与所述两个连接片的内表面相接处，减少了两个连接片在紧固时的弯曲程度，提高了两个连接片的使用寿命。
在上述实施例的基础上，所述连接杆13焊接在所述齿轮121的中心位置处。将连接杆13焊接在所述齿轮121的中心位置处，有利于所述齿轮121在与所述连接杆13固定连接后，在水平方向上不发生倾斜，提高了齿轮组12中齿轮121的啮合程度，以及齿轮组12在调节过程中工作的平稳性。
进一步地，所述摄像头11固定在所述齿轮121的中心位置处，由于所述摄像头11具有一定的重量，因此，摄像头11的位置设置在所述齿轮121的中心位置处，可保证齿轮121不会在不均匀受力的状况下发生倾斜，提高了齿轮121之间的啮合程度。
所述齿轮组12中齿轮121的半径以及齿数有多种设置方式，可以根据齿轮121上所固定的摄像头11的拍摄视角进行灵活设置。优选的是，所述多个齿轮121的半径相同，齿轮121也相同。如此设置，可以保证在控制单个齿轮121旋转一定的角度后，齿轮组12中的其他齿轮121同时可以旋转同样的角度，便于对齿轮组12的整体的操控，提高了调节效率。
此外，本申请实施例提供的立体摄像机1中的每个所述摄像头11上均延伸出用于传输数据的数据线16和用于给所述摄像头11提供电能的电源线17，本技术领域人员可以理解的是，所述摄像头11上也可以设置有其他的采集传输方式，如内存卡等；同样地，所述摄像头11上也可以设置有其他的电能供应方式，如电池等。
本申请实施例提供的立体摄像机1，其中包括的多个摄像头11用于获取图像，将多个所述摄像头11固定在齿轮组12中相互啮合的齿轮121上，通过齿轮121之间的相互转动，可以使与齿轮121固定的摄像头11随之发生转动，使摄像头11的摄像角度在水平方向可调，本申请实施例提供的立体摄像机1中还包括连接杆13，通过将连接杆13的另一端可拆卸地固定在其他设备上，可使与连接杆13固定的齿轮121的位置得以固定，进而保证了齿轮组12中的多个齿轮121的相对位置的固定。此外，还可以通过设置连接杆13的另一端固定时在竖直方向上具有一定的倾角，使所述立体摄像机1的摄像头11在竖直方向上具有一定的倾角，通过改变所述连接杆13的另一端的倾斜角度，从而达到使所述立体摄像机1的摄像角度在竖直方向上可调的效果。本申请实施例提供的立体摄像机1，可以灵活调节摄像头11的夹角和水平、竖直方向上的视角，增加了所述立体摄像机1与其他设备的关联性。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
