Description

可同时用于瞄准及照明的摄像装置 技术领域
本发明涉及一种可同时用于瞄准及照明的摄像装置， 尤其是仅通过一个光 源同时实现瞄准和照明的摄像装置。 背景技术
现在二维码的应用大多为用摄像头照相的方式取像。 为适应不同的环境光 线， 用摄像头照相的方式取像必须用一种光源将被取像的物件照明以得到清晰 的图像， 而目前这种面阵的照明光源一般都为发光二极管 （LED )。 发光二极管 的照明为一个模糊的光晕， 无法准确的将被照物对准， 故而经常需要再用一个 补助的瞄准光线来瞄准将被取像的物件。 目前常用的瞄准器一般可用发光二极 管或用激光通过透镜做成一个瞄准光线。 采用这两种取像方式均有其各自的先 天缺陷： 一是发光二极管的照明清晰度及均匀度很差 ,以致难以准确取像及成像 品质不好； 二是由于有三条光路一一摄像头成像光路、 发光二极管照明光路和 瞄准线光路， 对在景深范围内的被取像的物件难以达到一致的效果。

以下将结合本发明的不同实施实例对其进行描述。 本领域技术人员不通过 创造性劳动便可知悉可以通过多种不同的替代技术方案实现本发明的技术特征 和发明目的， 因此， 以下所描述的实施例仅仅是描述性的而非限制性的。
现有技术的摄像装置， 通常有两组光源： 一是照明光源； 二是瞄准光源， 照明光源和瞄准光源分别由一个或多个发光体组成。 图 1 是现有技术的摄像装 置结构示意图， 展示了现有常用的摄像装置中的一种。 如图所示， 摄像装置包 括第一发光单元 100、第二发光单元 200和摄像单元 300。其中第一发光单元 100 为照明光源， 将光照射在被拍摄物上， 第二发光单元为瞄准光源， 可发光形成 一瞄准线。 根据现有技术的摄像装置采用二个光源， 其中第一发光单元 100 为 单独专用的照明光源， 由四个发光体组成； 第二发光单元 200 为单独专用的瞄 准光源， 由二个发光体组成。 这种现有技术的摄像装置采用单独的照明光源和 单独的瞄准光源， 其发光单元的结构是比较复杂的， 需要的发光体是较多的， 由此整个产品的设计上也会变得更为复杂一些， 造成体积更大， 成本更高， 且 其对在景深范围内的被取像的物件难以达到一致的效果。
图 2是本发明摄像装置的结构视意图。 如图所示， 根据本发明的摄像装置， 包括发光单元 100和摄像单元 300。 发光单元 100发光形成明确轮虞的光照区， 用于将光瞄准并照射被拍摄物。 摄像单元 300获取光在被拍摄物的反射光像。 摄像单元 300的摄像区覆盖了发光单元 100发光形成的光照区。 这样， 在拍摄 时， 只要将光照区对准被拍摄物， 因为被拍摄物完全被光照区覆盖， 便可筒单 地获取被拍摄物的图像。 由于发光单元 100形成了明显轮廓的光照区， 在拍照 时， 要瞄准被拍摄物是十分容易的， 使用起来便十分便利， 尤其对被拍攝面较 小的被拍摄目标或者体积比较小的被拍摄物时， 使用本发明的摄像装置更是能 很好地实现了瞄准这一目的， 对提高的摄像效果和效率有很大的帮助。 如图所 示， 根据本发明， 使用一个发光单元便可同时实现照明和瞄准功能， 大大地筒 易和产品的结构， 及降低产品成本。
图 3是本发明一个优选实施例的发光单元的结构分解图。 如图所示， 发光 单元 100包括激光光源 101、 准直镜 102和复眼透镜 103。 复眼透镜 103、 准直 镜 102和激光光源 101 自被拍摄物往摄像装置方向依次排列。 激光光源 101发 出的激光束经由准直镜 102,由准直镜 102将激光光源 101所发出的单一波长光 平行并聚焦到复眼透镜 103。由准直镜 102和复眼透镜 103组成的透镜组将聚焦 的平行光扩展为一个方形的面光。 本发明的摄像装置选用的复眼透镜一般可以 选择苍蝇眼， 当然也可选用其他的复眼透镜。 通过苍蝇眼透镜可将激光扩展为 一个配合摄像单元 300的摄像头成像大小的矩形光投射在要被取像的物件上,一 方面可作为照明,并可清楚地显示光照区的位置， 同时有效地实现瞄准。 而苍蝇 眼透镜同时可消除由激光所产生的光斑。 由于激光所发出的为单一波长光， 极 易成型为形体分明的方形的面光， 故而不但可做照明之用， 且其形成明确的轮 廓， 亦可同时兼作瞄准,定位光源之用， 从而可以实现 "看到什么便捕捉到什么 图像！" 本发明选用准直镜， 这样有一定发散角的光线通过准直镜出来发散角很 小， 接近平行光。 复眼透镜是平行光通过很多个微型透镜变为有一定发散角的 方形光斑， 许多方形光斑组合成光照区， 实现了均勾照明。
图 4是本发明的摄像装置立体分解图。 如图所示， 发光单元 100在摄像单 元 300—侧， 发光单元 100的中轴线 100b与摄像单元 300的中轴线 300b相交， 形成夹角 tan。 此夹角大小可以根据实际设计需要而定， 一般可选为 1至 10度， 其中比较理想的夹角大小约为 5度。 根据本发明对夹角的设计， 发光单元 100 的中轴线 100a与摄像单元 300的中轴线 200不是平行的， 因此两者将会相交， 并形成一定的夹角， 这样才可成功且十分有效地实现摄像区覆盖光照区， 从而 实用发光单元 100的瞄准和照明的功能。
图 5是本明发又一个优选实施例的结构方框图。 如图所示， 根据本发明的 摄像装置， 包括激光发光单元 100, 激光驱动器 200, 摄像单元 300和数字信号 处理器 400。 激光发光单元 100形成明确轮虞的光照区 100a, 用于将光瞄准并 照射被拍摄物。 摄像单元 300获取激光发光单元 100发出的光在被拍摄物的反 射光像， 其摄像区 300a覆盖被光照区 100a。 数字信号处理器 400向激光驱动器 200发出照明信号和向摄像单元 300发出摄像信号。激光驱动器 200接收来自数 字信号处理器 400的照明信号后，驱动激光发光单元 100发光。进一步参考图 6, 发光单元 100包括激光光源 101、准直镜 102和复眼透镜 103。摄像单元 300 (二 维摄像头）与数字信号处理器 400电连接， 接受来自数字信号处理器 400 的拍 摄信号。 复眼透镜 103、 准直镜 102和激光光源 101 自被拍摄物往摄像装置方向 依次排列。 激光光源 101发出的激光束经由准直镜 102,由准直镜 102将激光光 源 101所发出的单一波长光平行并聚焦到复眼透镜 103。由准直镜 102和复眼透 镜 103组成的透镜组将聚焦的平行光扩展为一个方形的面光。 优选的， 发光单 元 100在摄像单元 300一侧， 发光单元 100的中轴线 100b与摄像单元 300的中 轴线 300b相交， 形成夹角 tan。 此夹角大小可以根据实际设计需要而定， 一般 为 1至 10度， 较为理想的夹角大小是约为 5度。 根据本发明对夹角的设计， 可 成功有效地实现摄像区覆盖光照区， 从而实用发光单元 100 的瞄准和照明的功 能。 根据本发明， 在摄像装置内设置有一个数字信号处理器 (DSP)400, 将经过 ADC数模转换器 401生成的数字信号处理,可以实用对各种图像比例的格式， 照 相快门的控制， 曝光控制， 信号输出格式， 图框大小设定， 像素整合处理， 自 动曝光， 自动白平衡， 自动增益控制等， 并可再经由接口端 500将数字化的影 像信号输出。 通过数字信号处理器 (DSP)400还可对摄像单元 300进行控制， 以 控制图像的桢率， 曝光， 快门， 对比度， 亮度， 像素， 噪声。 根据本发明的摄 像装置， 除了可以有效地实现瞄准被拍摄物和让摄像装置结构更筒单外， 还可 通过数字信号处理器 400对发光单元 100和摄像单元 300实现有效、 智能地调 节、 控制。
根据本发明的摄像装置， 可用于各种需求的影像捕获， 当然包括用于对条 形码图像的捕获， 尤其是像二维码这种被拍摄面较小的图像的捕获， 其效果是 非常好的， 快速便捷， 提高工作效率。 根据本发明的摄像装置， 筒化了摄像装 置的结构， 实现摄像装置体积更小， 从而也降低了成本， 并捕获更更真实的影 像。
在上述的描述中， 已充分公开了本发明的新的特性和优点。 然而， 这个公 开在许多方面仅仅是说明性的， 而不是限制性的。 在此公开的基础上， 本领域 的技术人员完全可以在不超出本发明范围的情况下， 在细节上或布置方面进行 变化， 包括对本发明的各种特征和优点的组合或分开使用。
