[0007] 其中:1为计算机;2为投影仪;3为Wiimote摄像头;4为标记器;5为投影屏幕。 [0007] wherein: a computer; 2 is a projector; 3 Wiimote camera; marker 4; 5 is a projection screen. 具体实施方式 detailed description

[0008] 下面结合附图对本实用新型做进一步详细描述:参见图1,一种基于Wiimote的红外虚拟现实教学系统,该虚拟现实教学系统由投影仪、投影屏幕、计算机、Wiimote摄像头和标记器构成;所述投影仪、Wiimote摄像头和标记器位于投影屏幕同侧并朝向投影屏幕正面;所述计算机分别与投影仪和Wiimote摄像头连接;所述计算机上设置有视频采集卡。 [0008] DRAWINGS further detailed description of the present invention do: Referring to Figure 1, a kind of virtual reality Teaching System Based Wiimote infrared, the virtual reality teaching system constituted by a projector, a projection screen, a computer, Wiimote camera and marker ; the projector, the camera and marker Wiimote projection screen located on the same side and facing the front projection screen; the computer are connected to the projector and the camera Wiimote; is provided with a video capture card on the computer. 所述Wiimote摄像头上设置有红外滤镜。 The Wiimote camera head is provided with an infrared filter.

[0009] 所述标记器是红外激光笔,该红外激光笔包括笔罩、笔身、触摸板、开关和红外激光灯。 The [0009] marker is an infrared laser pointer, the laser pointer comprising infrared pen cap, pen body, a touchpad, switches, and infrared laser light. 该虚拟现实教学系统系统由微型投影仪(或普通投影仪)、投影屏幕、计算机、 Wiimote摄像头和标记器组成。 The virtual reality system teaching system by the micro projector (projector or normal), projection screen, a computer, a camera and the Wiimote marker composition. 在虚拟现实教学笔的笔尖安装红外激光发射器,红外激光照射在虚拟现实教学系统屏幕上形成光斑,被Wiimote摄像头所捕获,图像经采集卡传递给计算机,并由图像处理算法计算得出笔尖相对于屏幕的位置,从而实现了笔尖的定位。 Mounted on the tip of the stylus VR teaching infrared laser emitter, an infrared laser irradiation spot is formed on the virtual reality screen teaching system, Wiimote are captured by a camera, the image is transmitted to the computer via the acquisition card, calculated by the image processing algorithm nib relative the position of the screen, enabling positioning tip. 然后利用笔的定位信息根据用户需求实现相应操作并生成图像,利用投影机将图像内容投影到教学屏幕上,以此来构造出一个大屏幕、交互式的协作会议或教学环境。 Then use the pen location information corresponding operation achieved according to the needs of the user, and generates an image using a projector image projected onto the teaching screen content, in order to construct a large-screen, interactive collaborative meetings or teaching environment. 另外系统支持便携式投影仪,可以携带在身上,对任何反射平面都可执行操作。 Further support for the portable projector system, can be carried on the body, you can perform any operation on the reflection plane. 系统分两种,一种是使用大型固定投影仪,为大班授课而设计,还有一种是使用微型投影仪,不但可用于小班授课,还可用于老师办公,比如改作业时可以直接把参考答案投射在作业本上。 When the system is divided into two, one is the use of large fixed projectors, designed to teach large classes, there is a projector using a micro, not only for small classes, the teacher can also be used for work, such work can be changed directly Answer projected on the present job.

[0010] 由于通常投影仪的投影镜头上装有红外截止滤镜,所以,投影出的光线中红外成分非常少。 [0010] Since the IR cut filter with the usual projector projection lens, so that the light projected infrared component is very small. 因此,在教学笔上安装红外激光发射器和激光控制开关,激光束打在屏幕上形成红外光光斑,可以被能够感应红外光的摄像头清晰的捕获。 Thus, mounting the infrared laser transmitter and a laser control switch, the laser beam hit the screen the infrared light spots are formed may be capable of sensing the infrared light camera capture clear teaching in the pen. 所得图像传给电脑,通过处理计算得到笔的位置从而进行相应处理,生成图像,利用投影机将图像内容投影到虚拟现实屏幕上。 The resulting image is transmitted to the computer, obtained by the processing for calculating the pen position to be processed, generates an image using a projector image projected onto the virtual reality content screen. 同时,在教学笔上安装功能按钮并通过无线方式发出信号,用USB接口的无线模块进行接收,发送给计算机可以实现对操作功能的扩展,完成鼠标右击,上下翻页等操作。 Meanwhile, the pen mounted on the function button and the teaching signal sent by wireless, radio receiving USB interface module, sent to the computer to realize the extended functionality of the operation, right click complete page up and down operations.

[0011] 其中,850nm红外滤镜可去除光线(投影光线和日光)中波长小于850nm的成分对虚拟现实教学系统笔发出的红外光点的干扰,增强了系统的鲁棒性,大大简化了系统结构设计的难度。 [0011] wherein, 850nm IR filter removing light components (the projected light and daylight) of wavelength less than 850nm infrared interference light pen point VR emitted teaching system, improves the robustness of the system, greatly simplifies system structural design difficulty.

[0012] 以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明,不能认定本发明的具体实施方式仅限于此,对于本发明所属技术领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干简单的推演或替换,都应当视为属于本发明由所提交的权利要求书确定专利保护范围。 [0012] The above content with the specific preferred embodiments of the present invention is further made to the detailed description should not be considered specific embodiments of the present invention be limited thereto, the present invention belongs to the technical field of ordinary skill in the art, without departing from the present invention concept premise, can make various simple deduction or replacement, should be deemed to belong to the present invention as claimed in claims submitted to determine the scope of protection.
