Description

一种广角摄像机
本申请要求于2015年7月14日提交中国专利局、申请号为201520510596.X、发明名称为“广角摄像机”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及安防设备，特别是涉及一种广角摄像机。
背景技术
随着电子通讯技术的飞速发展，监视摄像机及配套系统已经在各个行业上有了广泛的应用，能够为场景提供实时监控以及录像，为后续的场景再现需求提供实现基础。如安装在火车站等人流杂乱的地方，能在一定程度上遏制盗窃案的发生；安装在住宅区、超市的道路口可以提高此类区域的安全；安装在生产线上，可对产品质量进行监控；应用于交通路口可以实时监控车辆的运行情况。随着应用的普及和深入，现在人们对监控采集视频信息的要求也不断提高。
本申请的发明人经过长期的观察和研究后发现，受目前加工制造等工艺的限制，球型摄像机使用的透明罩只能加工半个完整的球面，往上只能用柱面衔接。摄像机安装在这样的透明罩中，其水平方向可360度无限制转动，垂直方向只能0度至90度转动。当摄像机的视场角位于球形区域时，其成像清晰，而当摄像机的视场角位于柱面时，将无法获得清晰的图像。当摄像机旋转到0度附近时，其部分图像需经过柱面来成像，像质不能满足要求，因此摄像机垂直方向的旋转角度受限于5度至90度，在实际应用中，用户希望摄像机能有更大的监控范围，但透明罩限制了摄像机功能的充分发挥。
发明内容
本申请所要解决的技术问题是为了克服现有技术中摄像机旋转到0度附近时，其部分图像需经过柱面来成像，像质不能满足要求的不足。
针对上述问题，本申请提出了一种广角摄像机，包括内壳体，还包括： 透明罩，包括半球壳以及与所述内壳体相连接的截球壳；摄像机，设置在所述透明罩内，所述半球壳位于所述摄像机的镜头的前方，以使所述摄像机的转动范围内，所述摄像机的镜头的视场角指向所述半球壳。
根据本申请的广角摄像机，在将摄像机安装到透明罩中的预定位置时，摄像机在0度至90度范围内的垂直转动过程中，镜头的视场角始终指向透明罩的半球壳，从而保证外部光线全部从透明罩的半球壳穿过并进入摄像机的镜头。这样，在摄像机随着内壳体一起水平转动和/或自身垂直转动的过程中，摄像机采集到的图像清晰度高，品质好。
在本申请的一种具体实现方式中，所述内壳体的端口为台肩，所述截球壳包括压在所述台肩的下表面上的环形凸缘。环形凸缘与台肩接触时，能够对透明罩进行定位，保证了透明罩安装位置的准确性。
在本申请的一种具体实现方式中，所述内壳体上设置有与所述环形凸缘相配合的环形槽，在所述透明罩与所述内壳体配合安装时，所述环形凸缘插入在所述内壳体上的环形槽内。环形凸缘插入在环形槽内，可以较好地实现透明罩和内壳体的连接。
在本申请的一种具体实现方式中，所述广角摄像机还包括压在所述环形凸缘的下表面上的环形板。环形板对环形凸缘形成限位，增加了透明罩与内壳体的连接的可靠性。
在本申请的一种具体实现方式中，所述摄像机水平转动的轴线与垂直转动的轴线有一交点，该交点距离所述半球壳的内表面的所有点的距离相等。摄像机转动到任一位置时，穿过半球壳的光线抵达摄像机的距离相同，保证摄像机采集到的图像清晰度高，品质好。
在本申请的一种具体实现方式中，所述广角摄像机还包括外壳体，所述内壳体设置在所述外壳体内部。外壳体对内壳体具有保护作用，防止内壳体受到外力冲击而发生损坏。
在本申请的一种具体实现方式中，所述截球壳的曲率与所述半球壳的曲率相等。截球壳的曲率与半球壳的曲率相等透明罩方便加工制造。
在本申请的一种具体实现方式中，所述截球壳的球心与所述半球壳的球 心重合。摄像机的水平转动与垂直转动的交点与该球心重合，便于将摄像机在透明罩内进行定位安装。
在本申请的一种具体实现方式中，所述半球壳包括第一环形端，所述截球壳包括第二环形端和第三环形端，所述第二环形端的端面与所述第三环形端的端面之间形成有夹角，所述第三环形端形成有所述透明罩的开口，以使所述摄像机穿过该开口而装入所述透明罩内。第三环形端形成有透明罩的开口，便于将摄像机穿过该开口装入透明罩内。
在本申请的一种具体实现方式中，所述第一环形端与所述第二环形端连接处形成有环形凸起，所述环形凸起围绕所述第一环形端的轴线周向延伸，并凸出所述透明罩内表面。该环形凸起具有标识和引导作用。
在本申请的一种具体实现方式中，所述截球壳被划分成多个区域，各相邻的所述区域之间形成有分界凸起。对截球壳进行区域划分便于使用相应模具来加工制造一体化的透明罩，从而克服现有加工制造技术只可以加工完整的半球壳透明罩的限制。

具体实施方式
下面将结合附图对本申请作进一步说明。
如图1所示，本实施例的广角摄像机10，可以包括具有防护功能的外壳体11。在外壳体11的空腔里设置有内壳体12。内壳体12的下端安装有球形透明罩13(即透明罩)。摄像机14位于该球形透明罩13内。内壳体12可以在外壳体11内围绕自身轴线进行水平转动，以带动球形透明罩13和摄像机14同步地水平转动98，从而摄像机14可以进行360度水平旋转拍摄。同时，如图4所示，摄像机14也可以围绕自身的旋转轴线在0度到90度之间的范围内垂直转动99。这样，随同内壳体12的水平转动98以及自身的垂直转动99的摄像机14，具有大范围的拍摄和监视能力。
需要说明的是，图1中仅仅示意出了广角摄像机10的一种具体实施方式，广角摄像机10的具体结构并不限于图1中所示的情况，举例而言，广角摄像机10也可以不具有外壳体11，这也是可行的。
如图3所示，本实施例的球形透明罩13包括半球壳131和与半球壳131曲率相同的截球壳132，且截球壳132的球心与半球壳131的球心重合。摄像机14包括有物镜。该物镜为摄像机14的镜头中的重要组成部分。物镜通过半球壳131对外部环境进行拍摄。外部同一点(广角摄像机10的拍摄范围内的点)的光线穿过球形透明罩13的半球壳131后进入物镜，从而在物镜中的成像重合，不会出现虚影，拍摄图像清晰，质量高。
需要说明的是，图3中仅仅示意出了广角摄像机10的一种具体实施方式，广角摄像机10的具体结构并不限于图3中所示的情况。举例而言，半球壳131的曲率与截球壳132的曲率也可以不相同，或者，截球壳132的球心与半球壳131的球心也可以不重合，只需保证在实际拍摄时，摄像机14的转动范围内，摄像机14的镜头的视场角指向半球壳131，这样外部同一点的光线能穿过球形透明罩13的半球壳131后进入物镜。
如图4所示，本实施例中，当摄像机14围绕自身的旋转轴线在0度至90度之间的范围内垂直转动时，摄像机14的转动范围内，摄像机14的镜头的视场角指向半球壳131，即使摄像机14自身的旋转轴线为0度，摄像机14的 镜头视场角在球形透明罩13上的辐射区域也均属于半球壳131，由于半球壳131各处的曲率半径均相同，故外部同一点的光线全部通过半球壳131进入物镜后，物镜中的成像会互相重合，这样可以较好地解决摄像机旋转到0度附近时，其部分图像需经过柱面来成像，像质不能满足要求的不足。
本实施例的球形透明罩13可以是一体成型结构。这样，下述的第一环形端1311与第二环形端1321仅是为了方便理解和描述。如图3所示，半球壳131包括第一环形端1311。截球壳132包括第二环形端1321和第三环形端1322。第二环形端1321的端面与第三环形端1322的端面之间形成有夹角。第三环形端1322形成有球形透明罩13的开口。摄像机14可以穿过该开口而装入球形透明罩13内。
如图3所示，第一环形端1311与第二环形端1321连接处形成有环形凸起15。该环形凸起15围绕第一环形端1311的轴线周向延伸，并凸出球形透明罩13内表面。该环形凸起15的球心与半球壳131的球心重合。该环形凸起15具有标识和引导作用，方便安装人员根据环形凸起15的位置准确调整球形透明罩13与物镜的相对位置，保证完成安装好的物镜在0度至90度范围内进行垂直转动99拍摄时，始终指向球形透明罩13上的半球壳131。物镜转动过程中不会扫过该环形凸起15，从而环形凸起15不会对物镜的图像采集造成影响。
具体地，物镜始终指向球形透明罩13上的半球壳131是指物镜的镜头视场角在球形透明罩13上的辐射区域始终属于半球壳131，而不属于截球壳132。
球形透明罩13的开口处设置有一圈环形凸缘1323。当环形凸起15与环形凸缘1323的下边沿相切时，环形凸缘1323完全设置在截球壳132的外周面上。当环形凸起15与环形凸缘1323的上边沿相切时，环形凸缘1323的一部分设置在半球壳131的外周面上。
内壳体12的端口为台肩，截球壳132包括压在台肩的下表面上的环形凸缘1323。具体地，如图2所示，该台肩可以为沿着内壳体12的下端口向外延伸的平台状结构，环形凸缘1323可以为沿着球形透明罩13的上端口向外延伸的平台状结构。这样，不管环形凸缘1323是完全设置在截球壳132的外周面上，还是部分设置在半球壳131的外周面上，在环形凸缘1323与该台肩接 触时，该台肩均能够对球形透明罩13进行定位，从而保证了球形透明罩13安装位置的准确性。
内壳体12上设置有与该环形凸缘1323相配合的环形槽。在球形透明罩13与内壳体12配合安装时，环形凸缘1323插入在内壳体12上的环形槽中，环形凸缘1323的外侧(即图2中所示的下表面)压有环形板97(如图2所示)。环形板97上设置有安装孔，螺钉穿过安装孔旋拧到内壳体12上的螺纹孔中以实现环形板97与内壳体12的固定连接，从而将环形凸缘1323压在环形槽中。
为了方便使用模具加工制造本实施例的一体成型的球形透明罩13，截球壳132被划分成多个区域。各相邻的所述区域之间形成有分界凸起16。可选地，分界凸起16直线延伸且起始端与终止端分别位于第二环形端1321和第三环形端1322，方便脱模。根据实际需要，该分界凸起16也可以通过后续加工工艺去除。
如图3所示，本实施例的截球壳132划分为第一区域S1、第二区域S2、第三区域S3、第四区域(由于第二区域S2的遮挡未示出)以及第五区域(由于第一区域S1的遮挡未示出)。其中，第一区域与第五区域形状相同。第二区域与第四区域形状相同。如图3所示，各相邻的所述区域之间形成有分界凸起16。使用模具加工制造本实施例的球形透明罩13时，完成脱模后的球形透明罩13的表面就出现各区域之间的分界凸起16以及上述的环形凸起15。
对截球壳132进行区域划分主要是便于使用相应模具来加工制造本实施例一体化的球形透明罩13，从而克服现有加工制造技术只可以加工完整的半球壳透明罩的限制。
如图4所示，摄像机14水平转动98的轴线与自身垂直转动99的轴线有一交点M，该交点M距离半球壳131的内表面的所有点的距离相同。这样，在摄像机14转动过程中，物镜距离球形透明罩13的半球壳131的内表面的各点距离相同，从而外部的光线穿过球形透明罩13的半球壳131后可以沿与半球壳131的内表面大致垂直的方向进入物镜。这样，物镜采集到的图像不会存在变形，图像清晰度高，品质好。
安装固定在内壳体12上的一体成型的球形透明罩13，可以有效阻止外部 的水汽或者灰尘进入。一体成型的球形透明罩13自身强度和刚度好，防爆性能优异，提升了球形摄像机10的安全性和可靠性。
借助本申请的实施例的描述可以发现，包括有截球壳132与半球壳131的球形透明罩13可以被加工制造成较小的尺寸。这样，用于安装固定包括有截球壳132与半球壳131的球形透明罩13的壳体体积较小，便于实现小型化的球形摄像机10的设计和加工制造。体积较小的球形摄像机10的加工制造成本较低，占用空间较小，安装灵活度更高，适应范围更广。
如图4所示，在将摄像机14安装到球形透明罩13中的预定位置时，物镜在0度至90度范围内的垂直转动99过程中，始终指向透明罩的半球壳131，从而保证外部光线全部从透明罩的半球壳131穿过并进入物镜。这样，在摄像机14随着内壳体12一起水平转动98和/或自身垂直转动99的过程中，物镜采集到的图像清晰度高，品质好。该预定位置可以是摄像机14水平转动98的轴线与自身垂直转动99的轴线的交点M距离半球壳131的内表面的所有点的距离相同的位置。
虽然已经参考优选实施例对本申请进行了描述，但在不脱离本申请的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
