技术领域
本发明涉及计算机技术领域, 特别是涉及人机交互系统及红外影像捕捉装 置。
背景技术
随着科技的发展, 计算机已经被广泛地应用在人们日常的工作和生活中。 在基于计算机视觉的人机交互技术中, 需要藉由摄像头来捕捉辨认用户的动作, 从而实现人机交互。 但是, 由于用户的动作一般比较复杂, 而且进行辨认的成 本较高, 因此典型的、 易于应用的人机交互技术包括让用户持有一个能够易于 供摄像头辨识的指示装置(例如红外点触笔等等), 通过辨认红外点触笔所输入 的红外光指示信号, 从而实现人机交互。 目前常用的基于投影的大型交互白板 就是这种典型的人机交互技术的一种实现方式, 其可以利用红外摄像头和红外 光发生器的配合以实现人机交互; 或者釆用经过处理的、 去除了红外滤光镜的 普通摄像头来捕捉红外光发生器所输入的红外光指示信号从 实现人机交互。
但是, 对于采用红外摄像头的人机交互系统来说, 由于红外摄像头价格昂 贵, 因此整个人机交互系统的成本较高, 不利于大范围的推广。
而对于采用改装的普通摄像头的人机交互系统来说, 由于采用成像器件-数 字微透镜装置 (Digital Micromirror Device, DMD)的数字光处理 (Di gitai Light Procession, DLP)模式的投影仪是通过逐个点扫描而成像的, 并且摄像头每秒 30 帧的快门只能拍摄到残缺的尚未扫描完整的画面, 因此经过改装的普通摄像头 无法正常捕捉 DLP模式的投影仪所投射的画面, 即摄像头和投影仪的帧率不一 致容易引发帧影像残缺的缺陷。 此外, 在强光环境下, 由于经过改装的普通摄 像头捕捉到的影像中红外光信号和可见光信号难以区分, 因此计算机难以分析 出红外光信号的所在位置, 从 ,¾导致人机交互的失效。
发明内容
本发明的目的在于, 克服现有的人机交互系统所存在的缺陷, 而提供一种 新的人机交互系统及红外影像捕捉装置, 该装置成本较低, 而且能够可靠准确 地捕捉影像中的红外光信号。
本发明的目的及解决其技术问题是采用以下技术方案来实现的。
本发明提供一种人机交互系统中的红外影像捕捉装置, 其包括影像捕捉装 置和可见光滤镜。 其中所述影像捕捉装置用于捕捉可见光信号和红外光信号。 所述可见光滤镜设置在所述影像捕捉装置之前, 以用于在影像进入所述影像捕 捉装置之前滤除所述投影影像中的可见光信号, 从而使所述影像捕捉装置捕捉 到所述影像中的所述红外光信号。
本发明还提供一种人机交互系统, 其包括计算处理装置、 投影装置、 红外 光发生器和红外影像捕捉装置。 所述投影装置与所述计算处理装置连接, 以将 所述计算机处理装置中的影像投射至投影区域从而产生投影影像。 所述红外光 发生器用于在所述投影影像上输出红外光指示信号。 所述红外影像捕捉装置用 于捕捉所述.投影影像中的所述红外光指示信号。 其中, 所述红外影像捕捉装置 包括影像捕捉装置和可见光滤镜。 所述影像捕捉装置用于捕捉可见光信号和红 外光信号。 所述可见光滤镜设置在所述影像捕捉装置之前, 以用于在所述投影 影像进入所述影像捕捉装置之前滤除所述投影影像中的可见光信号, 从而使所 述影像捕捉装置捕捉到所述投影影像中的所述红外光指示信号, 则所述计算机 处理装置根据所述红外光指示信号来执行湘应的操作。
本发明所提供的人机交互系统及红外影像捕捉装置是在影像捕捉装置前设 置可见光滤镜, 从而过滤掉可见光信号, 而让红外光信号通过, 达到并不需要 采用价格昂贵的红外光摄像头的目的, 因此其成本较低, 利于大范围的推广。 而且由于本发明所提供的红外影像捕捉装置只需要捕捉红外光指示信号, 其不 会和可见光信号相互混杂, 因此计算处理装置可易于准确地分析出红外光指示 信号的所在位置, 不会导致人机交互的失效, 并且该计算机处理装置也可以避 免由于光源、 投影仪、 影像捕捉装置不同帧率而造成的帧影像残缺的缺陷。
上述说明仅是本发明技术方案的概述, 为了能够更清楚了解本发明的技术 手段., 可以依照说明书的内容予以实施, 并且为了让本发明的上述和其他目的、 特征和优点能够更明显易懂, 以下特举较佳实施例, 并配合附图,详细说明如下。

图 2为图 1所示的红外影像捕捉装置 140的示意图。
具体实施方式

有关本发明的前述及其他技术内容、 特点及功效, 在以下配合参考图式的 较佳实施例的详细说明中将可被清楚呈现。 通过对具体实施方式的说明,可以更 加深入且具体的了解本发明为了达成预定目的所采取的技术手段及功效, 然而 所附图式仅是提供参考与说明之用 , 并非用来对本发明加以限制。
图 1 为本发明实施倒的人机交互系统的示意图。 如图 1所示, 本发明实施 例中的人机交互系统】00包括计算处理装置 110、 投影装置 120、 红外光发生器 】30、 以及红外影像捕捉装置 140。
计算处理装置 110 是指具有计算处理能力的计算系统, 例如具有中央处理 器 (Central Processing Unit, CPU)、 内存等电子器件, 并且还指具有操作系统能够 提供程序运行环境的计算系统。 具体地, 计算处理装置 110 可以利用各类电脑 设备来实现, 例如桌面电脑、 笔记本电脑、 平板电脑等等; 或者利用具有计算 处理能力的手持设备来实现, 例如智能手机等等; 或者利用其他具有计算处理 能力的机器人设备等等来实现。
投影装置 120与计算处理装置 110连接, 以用于将计算处理装置】10中的 影像投影至投影区域 190从而产生相应的投影影像。 其中, 投影装置 120可以 通过.投影装置接口 121 而与计算处理装置 110相连接, 而投影装置接口 〗21可 以包括视频图形阵列 (Video Graphic Array, VGA)接口、 复合视频输出接口。 高清 晰度多媒体接口(High Definition Muitimedm Interfeee, HDMI)等等。 当然,投影装 置 120也可以通过其他的有线或者无线连接方式来与升算处理装置 110相连接。
红外光发生器 130用于输出红外光信号, 以在投影区域 190上的投影影像 上产生红外光指示信号。 其中, 红外光发生器 130可以采用红外光激光器来实 现, 发射出的红外光激光束打在投影区域 190上从而形成红外光指示信号, 在 此, 红外光指示信号可以为红外光激光束光点。
红外影像捕捉装置 140与计算处理装置 110连接, 以用于捕捉.投影影像中 的红外光指示信号并将捕捉到的红外光指示信号输入至计算机处理装置 110,则 计算处理装置 110 可以确定红外光指示信号在投影影像中的所在位置, 从而实 现人机交互。
红外影像捕捉装置 140可以通过影像捕捉接口 14】 而与计算处理装置 1】0 相连接, 例如, 红外影像捕捉装置 140可以为 USB摄像装置, 其通过 USB接口 而与计算处理装置 110相连.接; 或者, 红外影像捕捉装置 140可以内置在计算 处理装置 110 内, 从而与计算处理装置 〗10相连接; 或者, 红外影像捕捉装置 140通过无线连接方式(例如 Wffi等方式)来与计算机处理装置 110相连接。 此外, 计算处理装置 110 中可以安装有控制软件, 以用于控制红外影像捕捉装 置 140进行工作, 从而捕捉投影影像中的红外光指示信号。
图 2为图 1所示的红外影像捕捉装置 140的示意图。 如图 2所示, 本发明 的红外影像捕捉装置 140包括影像捕捉装置 141和可见光滤镜 142。
其中, 影像捕捉装置 141 具有捕捉可见光信号和红外光信号的能力, 在本 发明中, 影像捕捉装置 141 可以采用不包括红外光滤镜的普通摄像头。 现有的 普通摄像头一般含有红外光滤镜, 本发明中的摄像头可以是经改装的将红外光 滤镜去除后的普通摄像头, 因此其可以在不增加成本的基础上, 使普通摄像头 具有捕捉可见光信号和红外光信号的能力。 当然, 本发明中的普通摄像头也可 以是在制作时就没有安装红外光滤镜的摄像头。
影像捕捉装置 141包括镜头 1411和设置在镜头 1411之后的感光元件 1412。 其中, 感光元件 1412可以采用电荷耦合元件 (Charge Coupled Device, CCD)或者 互补性氧化金属半导体 (Complementary Metal-Oxide Semiconductor)等等来实现。 当然, 本领域技术人员可以理解的是, 影像捕捉装置 141中的镜头 1411的数量 及类型可以根据需要而进行更换。
可见光滤镜 142设置在影像捕捉装置 141之前, 因此投影影像在进入影像 捕捉装置 141之前, 可见光滤鏡 142会过滤掉投影影像中的可见光信号, 而让 红外光指示信号通过, 则影像捕捉装置 141 只会捕捉到投影影像中的红外光指 示信号, 然后再将红外光指示信号输入至计算机处理装置 110, 最后 i 算机处理 装置 110 可以辨认确定出红外光指示信号在投影影像中的所在位置, 并根据红 外光指示信号来执行相关的操作, 从而实现人机交互。
此外, 如图 2 所示, 在本发明中, 红外影像捕捉装置 140还可以进一步包 括切换元件 143,其与可见光滤镜】42连接从而控制可见光滤镜 142收^或者放 下, 以实现使可见光滤镜 142能够选择性地设置在影像捕捉装置 140之前的目 的。 例如, 当人机交互系统 100 需要同时捕捉投影影像和投影影像中的红外光 指示信号时, 則可操控切换元件〗43将可见光滤镜 141收起, 那么影像捕捉装 置 140可同时捕捉可见光信号及红外光信号。 而当只需要捕捉投影影像中的红 外光指示信号时, 则可操控切换元件 143将可见光滤镜 141放下, 从而过滤掉 可见光信号, 以使影像捕捉装置 140只捕捉红外光信号。
因此, 本发明提供的人机交互系统及红外影像捕捉装置是在影像捕捉装置 前设置可见光滤镜, 从而过滤掉可见光信号, 以让红外光信号通过, 而并不需 要采用价格昂贵的红外光摄像头, 因此本发明提供的人机交互系统及红外影像 捕捉装置成本较低, 且由于本发明的红外影像捕捉装置只需要捕捉红外光指示 信号, 不会和其他的可见光信号发生相互混杂, 因此计算处理装置易于准确地 分析出红外光指示信号的所在位置, 不会导致人机交互的失效, 而且其也可以 避免光源、 投影仪、 影像捕捉装置不同帧率所引起的帧影像残缺的缺陷。
以上所述, 仅是本发明的较佳实施例而已, 并非对本发明作任何形式上的 限制, 虽然本发明已以较佳实施例揭露如上, 然而并非用以限定本发明,任何熟 悉本专业的技术人员, 在不脱离本发明技术方案范围内,当可利用上述揭示的技 术内容作出些许更动或修饰而形成等同变化的等效实施例,但凡是未脱离本发明 技术方案内容, 依据本发明的技术实质对以上实施例所作的任何简单修改、 等 同变化与修饰, 均仍属于本发明技术方案的范围内。
