具体实施方式
下面结合附图对本发明的技术方案进行说明。
实施例一
如图1所示，本发明提供一种用于空鼠设备的控制组件100，可包括：
一用于光标坐标检测的MCU(Microcontroller Unit，微控制单元)101和一用于图像拍摄显示设备的显示图像的摄像头102；
所述摄像头设于空鼠设备的前部位置，所述MCU101的信号输入端与所述摄像头102相连接；
所述MCU101的信号输出端连接空鼠设备的信号发射装置103，所述MCU通过该信号发射装置103与显示设备进行通信；
所述摄像头102用于拍摄显示设备的显示图像，所述MCU101接收所述显示图像，检测所述显示图像中红外光源的光源坐标，并通过所述信号发射装置103将光源坐标输出至显示设备，显示设备将光源坐标转换为光标坐标后，在对应的光标坐标处显示空鼠设备的光标。
摄像头102可设于空鼠设备的前部位置，该前部位置一般是指空鼠设备上朝向显示设备屏幕的那一端，从而便于拍摄显示设备的显示图像。在实际应用中，对于本身自带处理器的空鼠设备，MCU101还可由空鼠设备自带的处理器代替，或者，MCU101的输出端可以与处理器的输入端相连接，MCU101的输出数据可以进一步由处理器进行处理后，再经信号发射装置103发送到显示设备。
在一个实施例中，信号发射装置103可以采用射频信号发射装置。在另一个实施例中，显示设备可以包括但不限于智能交互平板、拼接墙、液晶电视等。为了便于控制组件100进行坐标转换，显示设备上可预先安装红外光源。由于红外光源的存在，显示图像上会存在红外像素点。摄像头102拍摄显示设备的 显示图像时，可以检测红外像素点在显示图像上的坐标，从而获取红外光源的光源坐标，并进行坐标转换，得到空鼠设备的光标坐标，然后通过信号发射装置103将光标坐标发送到显示设备。显示设备接收到光标坐标之后，可以在对应的光标坐标处显示光标图标。通过这种方式，可以实现对空鼠设备的光标的绝对定位。其中，从显示图像上检测红外像素点以及进行坐标转换均可采用现有的手段，本发明对此不做限定。
在进一步的实施例中，本发明的用于空鼠设备的控制组件100还可包括用于对信号发射装置103和MCU101进行供电的电源104；所述电源104连接在信号发射装置103和MCU101之间。该电源可以采用蓄电池、纽扣电池等体积较小的电源，以便减小整个控制组件100的体积。进一步地，上述蓄电池可采用充电电池，上述纽扣电池可采用可充电纽扣电池，从而进一步提高控制组件100的续航能力。
为了便于维修和更换，上述控制组件100可以可拆卸的形式安装在空鼠设备内部。
上述用于空鼠设备的控制组件100，利用摄像头拍摄显示图像，利用MCU检测显示设备的光源在显示设备的显示图像上的光源坐标，并通过信号发射装置将光源坐标发送至显示设备，由显示设备进行坐标转换后得到光标坐标，从而能够实现在显示设备上对空鼠设备的光标进行绝对定位，提高了定位效果。
实施例二
如图2所示，本发明还提供一种空鼠设备，可包括：用于空鼠设备的控制组件100；以及与所述控制组件的MCU相连接的信号发射装置103。
在一个具体的实施例中，空鼠设备可以是激光笔，但本发明不限于此。

进一步地，本发明的空鼠设备还可包括一用于容纳控制组件的外壳，外壳上可设置一通孔，用于安装摄像头102，控制组件100的其他部分可以安装在外壳内部。
上述空鼠设备，利用摄像头102拍摄显示图像，利用MCU101检测显示设备的光源在显示设备的显示图像上的光源坐标，并通过信号发射装置103将光 源坐标发送至显示设备，由显示设备进行坐标转换后得到光标坐标，从而能够实现在显示设备上对空鼠设备的光标进行绝对定位，提高了定位效果。
实施例三
如图3所示，本发明还提供一种与实施例二的空鼠设备配套使用的显示设备200，采用实施例二的空鼠设备进行控制；该显示设备200可包括：
液晶面板201和红外光源202；所述红外光源202设置在液晶面板201的后面或侧边；
所述液晶面板201接收空鼠设备发送的坐标数据，并在对应的坐标处显示空鼠设备的光标；其中，所述空鼠设备捕获液晶面板201上的红外光源，并发送坐标数据至液晶面板201。
其中，红外光源202可以设置在液晶面板201的后面，也可以设置在液晶面板201的侧边，通过导光柱进行光线角度改变。
上述红外光源202可采用红外LED(Light Emitting Diode，发光二极管)。由于红外LED发出的光线人眼不可见，因此，不会影响显示效果。红外光源202的数量可以是多个，其中，可在与液晶面板正中心对应的位置处设置一个红外光源，作为主红外光源，并在主光源周围设置若干个从红外光源。
在一个实施例中，本发明的显示设备还包括设置在所述液晶面板下方的红外滤光单元203，用于对所述红外光源进行滤光。在另一个实施例中，液晶面板201上可设有多个RGB显示单元，各个RGB显示单元分别用于进行图像显示。在另一个实施例中，所述红外光源202设置在液晶面板201的后面，红外光源202周围可均匀排布多个可见光光源204，用于发光，通过液晶面板201后产生不同的图案。在一些实施例中，液晶面板201与所述红外光源202之间还可设置一膜材205，用于扩散可见光，使光均匀的穿透液晶面板201。可选地，膜材205可以是扩散板、增光片或者扩散片。可选地，膜材205可以是光学参数可调的膜材。膜材205的光学参数可调，使红外光源202所发出的光穿透液晶面板201，具有一定的显示角度和大小，便于被摄像头捕获。
上述显示设备，利用摄像头拍摄显示图像，利用MCU检测显示设备的光源在显示设备的显示图像上的光源坐标，并通过信号发射装置将光源坐标发送至 显示设备，由显示设备进行坐标转换后得到光标坐标，从而能够实现在显示设备上对空鼠设备的光标进行绝对定位，提高了定位效果。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
作为其中一个应用实施例，如图4所示，本发明的用于空鼠设备的控制组件、空鼠设备和显示设备可采用以下定位方式进行定位：
在进入定位功能模式之后，首先通过摄像头捕获显示图像，然后由MCU在显示图像中检测主红外光源。若检测到，则记录主红外光源在显示图像中的光源坐标(x0，y0)，将光源坐标(x0，y0)发送到显示设备；若未检测到，可记录其中两个从红外光源在显示图像中的光源坐标(x1，y1)和(x2，y2)，将光源坐标(x1，y1)和(x2，y2)发送到显示设备。显示设备获取到光源坐标后，计算光标坐标(x，y)。
应当说明的是，摄像头可以识别不同波段红外，优先把中心主光源做参考。
多点红外光源定位示意图如图5所示，图中示出了一个分辨率为W1×H1＝1920×1280的显示图像，假设主红外光源为940nm波段的光源，从红外光源包括900nm波段的光源以及850nm波段的光源，则当捕获到940nm波段的光源时，认为捕获到主红外光源，记录该主红外光源的光源坐标(x0，y0)；假设仅捕获到900nm波段的光源以及850nm波段的光源，则认为仅捕获到从红外光源，记录这两个从红外光源的光源坐标(x1，y1)和(x2，y2)。中心的红外光源为主红外光源，当在显示图像上捕获到主红外光源时，优先处理，计算在画面中的坐标(x0，y0)。因摄像头角度问题，当只采集到从红外光源时，以当前 采集到的从红外光源做参考点，计算参考点在显示图像中的坐标。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
