When the remote control unit 20 In normal use, the motion sensor captures the vibration signal, and the infrared light power supply system is turned on. At this time, the infrared emission module 21 is controlled to emit infrared light by using the illumination control button 25; when the remote control unit 20 After standing for a period of time, such as 30s~60s, the motion sensor does not capture the vibration signal during this time, and automatically cuts off the infrared light supply system of the remote control unit 20, so that the remote control unit 20 The infrared light cannot be emitted, so that the remote control unit 20 is more power-saving, and can be used for a longer period of time without replacing the battery or charging; and when the person picks up the remote control unit 20 After that, the motion sensor immediately captures the vibration signal, turns on the infrared light supply system, and returns the remote control unit 20 to normal operation. To ensure infrared spot 26 With sufficient brightness and suitable size, it is preferable to use an infrared laser that emits collimated light or an exit light angle of less than 2 degrees as the infrared light emitting module 21 .

The touch sensing chip on the outer casing detects the touch signal by the touch sensing sensor connected to the touch sensing chip, and transmits the touch signal to the micro processing chip, and the micro processing chip controls the remote control signal transmitting component to emit infrared light after receiving the touch signal, so that the remote control The indicator lights up to show the remote unit The infrared light source of 20 is turned on, and the infrared light emitting module 21 can emit infrared light. When the user temporarily uses the remote control unit 20 The touch sensing sensor does not receive the touch signal, the micro processing chip controls the remote control signal transmitting component to enter the standby state, the remote control indicator is turned off, the infrared light source of the remote control unit 20 is disconnected, and the infrared light emitting module is turned off. 21 Unable to emit infrared light; when the user has not used the remote control unit for more than 30 minutes 20 The touch sensing sensor does not detect the touch signal, so that the micro processing chip controls the remote control signal transmitting component to be turned off, the remote control indicator is turned off, and the micro processing chip is in a power down state. Control the remote control unit in time with the touch sensing control unit 20 The infrared light source is turned on and off, and when the remote control unit 20 is suspended or used for a long time, the infrared light source is automatically turned off, and the remote indicator light is turned off to achieve the purpose of power saving.
图 1 中，红外摄像单元 40 设置在显示单元 10 显示面的正对面，捕获显示面上的红外光斑 26 的光斑图像信息。图 1 中红外摄像单元 40 可以是带红外线滤光片或带红外镜头的摄像机 / 摄像头，由于红外摄像单元 40 滤除了可见光，其捕获的图像信息中包含的数据量大为减少，有利于在主控单元 30 中快速而高效地识别该红外光斑 26 的图像。主控单元 30 根据来自红外摄像单元 40 捕获的图像信息进行信息处理后在显示单元 10 的显示画面上的 红外光斑 26 相应的位置上显示图标 11 。主控单元 30 内置有 图像处理芯片和显示芯片。图像处理芯片对接收到的光斑图像信息进行图像预处理、灰度化、边缘检测、位置识别等操作，获取红外光斑 26 在显示画面中的位置坐标数据。显示芯片根据位置坐标数据产生显示信息以控制显示单元 10 在其显示画面中红外光斑 26 相应的位置外显示图标 11 。主控单元 30 可以根据不同的应用选择不同的实现形式，如在空间充裕的场合可使用如 PC 主机作为主控单元 30 ；在空间狭小的场合，也可使用如嵌入式***作为主控单元 30 。 In Fig. 1, the infrared camera unit 40 is disposed directly opposite the display surface of the display unit 10, and captures the infrared spot on the display surface. Spot image information. Figure 1 The infrared camera unit 40 can be an infrared filter or a camera/camera with an infrared lens, due to the infrared camera unit 40 By filtering out visible light, the amount of data contained in the captured image information is greatly reduced, which facilitates rapid and efficient recognition of the image of the infrared spot 26 in the main control unit 30. Main control unit 30 according to the infrared camera unit 40 The captured image information is subjected to information processing and the icon 11 is displayed at the corresponding position of the infrared spot 26 on the display screen of the display unit 10. Main control unit 30 has built-in Image processing chip and display chip. The image processing chip performs image preprocessing, grayscale, edge detection, position recognition, etc. on the received spot image information to obtain an infrared spot.

The display chip generates display information based on the position coordinate data to control the display unit 10 to display the icon 11 outside the corresponding position of the infrared spot 26 in its display screen. Master unit 30 Different implementations can be selected according to different applications. For example, in a space-rich occasion, a PC host can be used as the main control unit 30. In a small space, an embedded system can also be used as the main control unit. 30.
当用户改变遥控单元 20 的指向使红外光斑 26 移动后，***需要经过一个时间间隔才能完成上述摄像、图像处理和显示图标的处理过程，在红外光斑 26 的当前位置重新显示图标 11 。这一时间间隔为***响应时间，为避免***响应时间过长，产生显示滞后的问题，整个处理过程的执行频率与显示画面的刷新频率（ 60HZ 以上）一致，使用户感觉到图标 11 随着遥控单元 20 的指向的改变而实时地移动，以模拟鼠标控制图标 11 移动，实现用户与显示画面的交互。相比于鼠标，遥控单元 20 具有突出的移动性，所以使用起来更加方便。 在演示过程中，仅仅控制图标移动是不够的，用户还常常需要与显示画面进行其他交互操作，比如单击、拖动等操作，以完成演示。 When the user changes the pointing of the remote control unit 20 to make the infrared spot 26 After moving, the system needs to go through a time interval to complete the above process of camera, image processing and display icons, and redisplay the icon at the current position of the infrared spot 26 . This time interval is the system response time. In order to avoid the system response time is too long, the display lag is generated. The execution frequency of the whole process is consistent with the refresh rate of the display screen (above 60HZ), so that the user feels the icon. 11 Moves in real time as the pointing of the remote control unit 20 changes to simulate the movement of the mouse control icon 11 to effect user interaction with the display screen. Remote control unit 20 compared to mouse It has outstanding mobility, so it is more convenient to use. In the demonstration process, it is not enough to control the movement of the icon. Users often need to perform other interactions with the display screen, such as clicking and dragging, to complete the demonstration.

Compared with the embodiment 1, the main control unit 30, the infrared imaging unit 40 and the projection unit are disposed in the same housing 15 The power supply of the main control unit 30, the infrared camera unit 40 and the projection unit can be further integrated to streamline the first switch circuit, the second signal receiving module 13 and the second switch circuit, and the main control unit 30 The first signal receiving module 31 receives the power remote control signal and is controlled by the main control unit 30 to turn the system on and off.
投影单元内置有投影物镜，投影物镜包括分光元件 124 和可移动的第一镜片组 121 以及用以驱动第一镜片组 121 进行移动的调焦组件 122 ；红外发光模块 21 发射的红外光束经过第一镜片组 121 、分光元件 124 后传送至红外摄像单元 40 。红外摄像单元 40 包括摄像物镜 41 和感应芯片 42 ，经过分光元件 124 的红外光束经摄像物镜 41 后通过感应芯片进行摄像。本实施例中，将投影单元的投影物镜 12 与红外摄像单元 40 的摄像物镜 41 集成于一体，共用一组镜片进行出光。投影单元的投影物镜 12 还包括可选的第二镜片组 125 ，分光元件 124 和第二镜片组 125 为固定结构 。在投影过程中，可见光线（由图 5 中的 A 表示）直接通过分光元件 124 和第一镜片组 121 投射到投影面上，而遥控单元 20 中的红外发光模块 21 发出的红外光束经过投影面的反射（由图 5 中的 B 表示），经过第一镜片组 121 到达分光元件 124 时，红外光被反射到红外摄像单元 40 内。这样使得红外摄像单元 40 的摄像物镜 41 与投影物镜 12 的光轴为同轴（如图 5 所示），投影物镜 12 和摄像物镜 41 的光轴同轴可确保调焦组件 122 在驱动第一镜片组 121 移动使得投影物镜 12 实现聚焦清晰时感应芯片 42 捕获的红外摄像画面也同步地满足摄像要求。分光元件 124 可以 为分光棱镜，该分光棱镜进一步包括两块相互粘接的直角棱镜（如图 5 所示），两直角棱镜的粘接面上设有分光膜 123 。 The projection unit has a projection objective lens, and the projection objective lens includes a beam splitting component 124 and a movable first lens group 121 and a driving lens group 121 The moving focusing component 122; the infrared light beam emitted by the infrared light emitting module 21 is transmitted to the infrared imaging unit 40 through the first lens group 121 and the beam splitting component 124. Infrared camera unit 40 includes a camera objective 41 and a sensor chip 42. The infrared beam passing through the beam splitter 124 passes through the objective lens 41 and is imaged through the sensor chip. In this embodiment, the projection objective of the projection unit is 12 The camera lens 41 of the infrared camera unit 40 is integrated and integrated with a set of lenses for light extraction. The projection objective 12 of the projection unit also includes an optional second lens set 125, the beam splitting element 124 And the second lens group 125 is a fixed structure. During projection, visible light (represented by A in Figure 5) passes directly through beam splitting element 124 and first lens group 121. Projected onto the projection surface, and the infrared beam emitted by the infrared illumination module 21 in the remote control unit 20 is reflected by the projection surface (represented by B in FIG. 5), passes through the first lens group 121, and reaches the beam splitting element. At 124, infrared light is reflected into the infrared camera unit 40. Thus, the imaging objective lens 41 of the infrared imaging unit 40 is coaxial with the optical axis of the projection objective lens 12 (as shown in FIG. 5), and the projection objective lens 12 is coaxial with the optical axis of the objective lens 41 to ensure that the focusing component 122 senses the chip 42 when the first lens group 121 is driven to move so that the projection objective 12 is sharply focused. The captured infrared camera image also satisfies the imaging requirements simultaneously. The beam splitting element 124 may be a beam splitting prism, and the beam splitting prism further comprises two right angle prisms bonded to each other (Fig. 5). As shown in the figure, a prismatic film 123 is provided on the bonding surface of the two right-angle prisms.
由于红外摄像单元 40 与投影单元共用一套成像***，投影画面聚焦清晰后，无论在任何工作距离，其在感应芯片 42 上对应形成的感应画面位置和尺寸是固定的。具体来说，投影单元与红外摄像单元 40 之间应满足以下关系： Since the infrared camera unit 40 shares a set of imaging systems with the projection unit, the projection picture is sharply focused, and at any working distance, it is in the sensing chip. The position and size of the sensing screen formed on the 42 is fixed. Specifically, the following relationship should be satisfied between the projection unit and the infrared camera unit 40:
（ 1 ）、当投影单元中显示芯片（未在附图中绘出）的有效面积大于投影画面在感应芯片 42 上可对应形成的红外摄像画面的面积时，摄像物镜 41 的光学放大倍率大于从分光元件 124 到显示芯片的光学***的放大倍率。 (1) When the effective area of the display chip (not shown in the drawing) in the projection unit is larger than the projection picture on the sensing chip 42 When the area of the infrared imaging screen formed is corresponding to the upper surface, the optical magnification of the imaging objective 41 is larger than the magnification of the optical system from the spectral element 124 to the display chip.
（ 2 ）、当投影单元中显示芯片的有效面积小于投影画面在感应芯片 42 上可对应形成的红外摄像画面的面积时，摄像物镜 41 的光学放大倍率小于从分光元件 124 到显示芯片的光学***的放大倍率。 (2) when the effective area of the display chip in the projection unit is smaller than the projection picture on the sensing chip 42 When the area of the infrared imaging screen formed is corresponding to the upper surface, the optical magnification of the imaging objective 41 is smaller than the magnification of the optical system from the spectral element 124 to the display chip.
（ 3 ）、当投影单元中显示芯片的有效面积等于投影画面在感应芯片 42 上可对应形成的红外摄像画面的面积时，摄像物镜 41 的光学放大倍率等于从分光元件 124 到显示芯片的光学***的放大倍率。 (3) when the effective area of the display chip in the projection unit is equal to the projection picture on the sensing chip 42 When the area of the infrared imaging screen formed is corresponding to the upper surface, the optical magnification of the imaging objective 41 is equal to the magnification of the optical system from the spectral element 124 to the display chip.
另外，为了保证红外摄像单元 40 没有死角，从投影平面反射回来进入感应芯片 42 形成红外摄像画面的红外光的光路在第一镜片组 121 上的第一透镜表面处的光线角度，应大于或等于投影光在第一透镜表面处的出射光线角度。 In addition, in order to ensure that the infrared camera unit 40 has no dead angle, it is reflected from the projection plane and enters the sensing chip 42. The angle of the ray at the first lens surface on the first lens group 121 forming the optical path of the infrared light of the infrared imaging picture should be greater than or equal to the angle of the outgoing light of the projected light at the first lens surface.
将红外摄像单元 40 的摄像物镜 41 与投影单元的投影物镜 12 集成为一体的优点是：投影单元的投影画面和红外摄像单元的摄像物镜 41 的聚焦平面重合一致，使得红外摄像单元 40 上的感应区域可以尽可能的大，使图像分辨率更高，亮度均匀性更好，图像失真小。由于第一镜片组 121 同时满足投影物镜与摄像物镜 41 的调焦需求，所以当投影画面聚焦清晰时，红外光斑 11 在感应芯片 42 上的成像也满足主控单元 30 对图像处理的要求，从而可极大的方便用户使用。由于红外摄像单元 40 与投影单元共用一套成像***，在投影画面聚焦清晰时，摄像画面在感应芯片 42 上的对应感应区域位置和尺寸都是固定的，不会随着投影画面的大小变化而变化。 The objective lens 41 of the infrared imaging unit 40 and the projection objective of the projection unit 12 The integration is integrated as follows: the projection picture of the projection unit and the focus plane of the imaging objective lens 41 of the infrared camera unit coincide with each other, so that the infrared camera unit 40 The sensing area on the surface can be as large as possible, resulting in higher image resolution, better brightness uniformity, and less image distortion. Since the first lens group 121 satisfies both the projection objective and the imaging objective 41 The focus adjustment needs, so when the projection picture is sharply focused, the imaging of the infrared spot 11 on the sensor chip 42 also satisfies the main control unit 30 The requirements for image processing can be greatly facilitated by users. Since the infrared imaging unit 40 shares a set of imaging systems with the projection unit, when the projection picture is sharply focused, the imaging picture is on the sensing chip 42. The position and size of the corresponding sensing area on the top are fixed and do not change as the size of the projected picture changes.
