本发明实施例提供了一种应用于多屏共享的分屏显示方法, 下面 将结合附图, 对本发明实施例进行详细描述。 该方法中包括主显示设 备和至少一个共享显示设备组成 "显示墙" 。 如图 1示出的应用于多 屏共享的分屏显示方法的流程, 包括以下步骤: The embodiment of the present invention provides a split screen display method applied to multi-screen sharing. The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

步骤 S102: 主显示设备接收分屏共享请求信息, 根据分屏共享请 求信息所传输的时间计算出主显示设备与共享显示设备之间的距离, 并依据所述距离判断是否可接受分屏共享请求, 并据此反馈相应的信 台
主显示设备记录接收到所述分屏共享请求信息的时间 T2, 并读取 发送该分屏共享请求信息的时间 Τ1 依据分屏共享请求信息所传输的 时间判断出主显示设备与共享显示设备之间的距离 S。 依据距离测算 公式: S=V ( Τ2 -Τ! ) , 其中 V表示分屏共享请求信息的传输速率, 即无线传输速率。 Step S102: The main display device receives the split screen sharing request information, calculates the distance between the main display device and the shared display device according to the time transmitted by the split screen sharing request information, and determines whether the split screen sharing request is acceptable according to the distance. And based on this feedback to the corresponding letter desk Recording the received main display device to the screen sharing request divided time information T 2, and transmits the read-screen sharing request time information Τ 1 split screen sharing request based on time information transmitted is determined that the main display device and the shared display The distance S between the devices.

The display proceeds to step S104.
步骤 S 103 :主显示设备向共享显示设备发送反馈拒绝分屏共享请 求的信息, 结束本流程。 Step S103: The main display device sends feedback to the shared display device to reject the split screen sharing request, and the process ends.

The feedback information may also include screen parameter information of the main display device.
由上, 主显示设备与共享显示设备完成分屏共享连接的建立。 步骤 S20: 确定出主显示设备与共享显示设备的空间坐标。 From above, the main display device and the shared display device complete the establishment of the split-screen shared connection. Step S20: Determine the spatial coordinates of the main display device and the shared display device.
本实施例中还包括定点设备, 定点设备与主显示设备以及共享显 示设备处于同一无线网络内, 用于根据定点设备测算主显示设备以及 共享显示设备的空间坐标。 In this embodiment, the pointing device is further included, and the pointing device is in the same wireless network as the main display device and the shared display device, and is configured to measure the spatial coordinates of the main display device and the shared display device according to the pointing device.
定点设备的坐标相对固定, 故以定点设备为基准进行该共享显示 设备空间坐标的测算。 如图 3所示, 其空间坐标的测算步骤包括: 步骤 S201 : 计算至少三个定点设备到该主显示设备的距离。 The coordinates of the pointing device are relatively fixed, so the space coordinate of the shared display device is measured based on the pointing device. As shown in FIG. 3, the measuring steps of the spatial coordinates include: Step S201: Calculate the distance of at least three pointing devices to the main display device.
如图 3所示该主显示设备与定点设备的位置示意图, 在本实施例 中, 三个定点设备的空间坐标分别为 a ( Xa,Ya,Za ) 、 b ( Xb,Yb,Zb ) 和 c ( Xc,Yc,Zc ) , 在该三个定点设备上安装有红外、 蓝牙、 WIFI或 超声波等无线收发模块。 相应的, 在所述主显示设备中同样安装有对 应的无线收发模块。 可依据无线信号传输的衰减程度计算出信号传输
的距离, 例如依据接收信号的强度指示 ( RSSI, Received Signal Strength Indicator )公式 PR=PT/Sn, 可分别计算出上述三个定点设备与 该主显示设备的距离 Sa、 Sb和 Sc。 其中, ?!^表示接收方无线信号的 接收功率, Ρτ表示发送方无线信号的发射功率, S表示无线信号收发 装置之间的距离, η为传播因数, 空气中 η取值可为 3。 FIG. 3 is a schematic diagram showing the position of the main display device and the pointing device. In this embodiment, the spatial coordinates of the three pointing devices are a ( Xa, Ya, Za), b ( Xb, Yb, Zb ) and c, respectively. (Xc, Yc, Zc), wireless transceiver modules such as infrared, Bluetooth, WIFI or ultrasonic are installed on the three fixed point devices. Correspondingly, a corresponding wireless transceiver module is also installed in the main display device. Signal transmission can be calculated according to the degree of attenuation of wireless signal transmission The distance, for example, according to the received signal strength indicator (RSI, Received Signal Strength Indicator) formula P R = P T /S n , the distances S a , S b of the above three pointing devices and the main display device can be respectively calculated. S c . among them, ? ! ^ denotes the received power of the receiver's wireless signal, Ρ τ denotes the transmit power of the sender's wireless signal, S denotes the distance between the wireless signal transceivers, η is the propagation factor, and η in the air may take 3.
步骤 S202:根据上述结果及上述三个定点设备的空间坐标计算该 主显示设备的空间坐标。 Step S202: Calculate the spatial coordinates of the main display device according to the above result and the spatial coordinates of the three pointing devices.
假设该主显示设备的空间坐标为 (Χ,Υ,Ζ) , 那么依据投影以及 勾股定理可得出下列计算式: Assuming that the spatial coordinates of the main display device are (Χ, Υ, Ζ), then according to the projection and the Pythagorean theorem, the following formula can be derived:
Sh=^(X-Xb)2+(Y-Yb)2 +(Z-Zb)2、 和S h =^(XX b ) 2 +(YY b ) 2 +(ZZ b ) 2 , and
由上述三组计算式便可推导出该主显示设备的空间坐标 ( Χ,Υ,Ζ ) 。 The spatial coordinates (Χ, Υ, Ζ) of the main display device can be derived from the above three sets of calculation formulas.
该步骤的计算可由主显示设备计算, 也可由定点设备进行计算, 上述计算信号传输距离所需要的参数及计算主显示设备空间坐标所 需要的参数可通过之前建立的无线连接交互。 The calculation of this step can be calculated by the main display device or by the pointing device. The parameters required for calculating the signal transmission distance and the parameters required for calculating the spatial coordinates of the main display device can be exchanged through the previously established wireless connection.
关于该主显示设备坐标的计算, 还可以由其他定位技术实现, 如 设置于屋顶或较高位置上的摄像头获取包括定点设备和该主显示设 备的全局图像, 通过图像分析该主显示设备的位置进行定位。 另外, 通过一个摄像头获取的图片可获得水平投影的各个共享设备的投影, 通过两个及两个以上的摄像头, 则可计算出该主显示设备的空间坐 标。 The calculation of the coordinates of the main display device can also be implemented by other positioning technologies, such as a camera set on a roof or a higher position to acquire a global image including the pointing device and the main display device, and analyze the position of the main display device through images. Positioning. In addition, the picture acquired by one camera can obtain the projection of each shared device of the horizontal projection, and the spatial coordinates of the main display device can be calculated by two or more cameras.
同理, 采用上述方法测算出各个共享显示设备的空间坐标 Similarly, using the above method to calculate the spatial coordinates of each shared display device
(Χ',Υ',Ζ' ) , 不再赘述。 (Χ',Υ',Ζ'), no longer repeat.
步骤 S30: 根据所计算出的主显示设备与共享显示设备的空间坐 标, 初步判断共享显示设备相对主显示设备屏幕的位置是否进入设定 距离, 并在进入设定距离后才 据所述空间坐标判断出相对于主显示设 备屏幕的方向。
其中, 依据上述主显示设备和共享显示设备的空间坐标, 确定出 共享显示设备相对主显示设备的方向。 所述位置用来判断共享显示设 备是否进入主显示设备的设定距离内, 即是否靠近主显示器, 所述方 向用来判断共享显示设备位于主显示设备的上下左右哪个方向上。 Step S30: According to the calculated spatial coordinates of the main display device and the shared display device, initially determine whether the position of the shared display device relative to the main display device screen enters the set distance, and according to the space coordinate after entering the set distance The direction relative to the main display device screen is determined. The direction of the shared display device relative to the main display device is determined according to the spatial coordinates of the primary display device and the shared display device. The location is used to determine whether the shared display device enters the set distance of the main display device, that is, whether it is close to the main display, and the direction is used to determine which direction the shared display device is located in the up, down, left, and right directions of the main display device.
另外, 考虑到在步骤 30中的定位精度, 当执行完步骤 S30后, 还可进一步执行主显示设备与共享显示设备的近距离定位, 作为辅助 定位, 下面进行详细介绍。 In addition, in consideration of the positioning accuracy in the step 30, after the step S30 is performed, the close positioning of the main display device and the shared display device can be further performed as the auxiliary positioning, which will be described in detail below.
如图 4〜图 7所示,在主显示设备的屏幕四边的边框内,设置若干 微型电磁铁 51 (其中仅显示了共享显示设备与主显示设备相邻边框的 部分微型电磁铁) , 在共享显示设备屏幕四边的边框内匹配的若干位 置也设置若干微型电磁铁 51,。 微型电磁铁的磁极方向垂直屏幕四边 的设置, 通过一切换开关控制对该微型电磁铁的供电以及供电的电流 方向, 来控制磁极方向。 当共享显示设备与主显示设备相贴放置时, 通过改变共享显示设备和主显示设备的电流方向, 使其产生的磁极异 性相对, 由此, 通过磁力, 使得主显示设备与共享显示设备相吸合, 由此可减小二者间的缝隙, 从而提供更好的分屏显示效果。 As shown in FIG. 4 to FIG. 7, in the frame on the four sides of the screen of the main display device, a plurality of micro electromagnets 51 (in which only a part of the micro electromagnets sharing the display device adjacent to the main display device) are displayed, in sharing A number of miniature electromagnets 51 are also provided at a number of locations within the bezel of the four sides of the display device screen. The magnetic pole direction of the micro electromagnet is arranged on the four sides of the vertical screen, and the direction of the magnetic pole is controlled by controlling the direction of the power supply to the micro electromagnet and the current supplied by a switch. When the shared display device is placed in contact with the main display device, by changing the current direction of the shared display device and the main display device, the generated magnetic poles are opposite to each other, thereby causing the main display device to attract the shared display device by magnetic force. Thus, the gap between the two can be reduced, thereby providing a better split screen display effect.
当共享显示设备与主显示设备之一设置上述微型电磁铁时, 只需 要控制进行供电即可对另一设备屏幕边框的吸合(前提是未安装电磁 铁的屏幕边框采用铁材质) , 而当共享显示设备与主显示设备均设置 有上述微型电磁铁时, 则需要控制供电及供电的电流方向, 以保证两 显示设备相贴的屏幕边框的磁极相异以吸合。 When one of the shared display device and the main display device is provided with the above-mentioned micro electromagnet, it is only necessary to control the power supply to pull the screen frame of the other device (provided that the screen frame without the electromagnet is made of iron), and When the shared display device and the main display device are both provided with the above-mentioned micro electromagnets, it is necessary to control the current direction of the power supply and the power supply to ensure that the magnetic poles of the screen frames attached to the two display devices are different to attract.
另外, 为检测共享显示设备与主显示设备贴合位置, 以确定扩展 图像的播放窗口, 还可在上述微型电磁铁位置设置磁感应装置, 当所 述微型电磁铁被吸合时, 则可由对应该位置的磁感应装置检测出来, 例如根据磁通量大小、 磁力大小进行检测, 这样, 根据所述边框内的 若干微型电磁铁被分别对应各自位置的磁感应装置检测被吸合时, 所 述装置便可由上报信息的磁感应装置, 确定出哪些位置的微型电磁铁 被吸合, 从而确定出共享显示设备位于主显示设备具体的相对位置。
如图 4对应的电磁铁 R01〜R07的磁感应装置都可检测到磁力或 磁通为最大时, 则表示电磁铁 L01〜L07恰分别与电磁铁 R01〜R07位 置——对应, 从而根据确定出的相贴合的位置, 确定扩展图像部分的 播放, 对于本例, 即检测出相贴合高度恰与共享显示设备高度相同。 In addition, in order to detect the position where the shared display device is attached to the main display device to determine the play window of the extended image, the magnetic induction device may be disposed at the position of the micro electromagnet, and when the micro electromagnet is attracted, it may be correspondingly The magnetic induction device of the position detects, for example, the detection according to the magnitude of the magnetic flux and the magnitude of the magnetic force. Thus, when the micro-electromagnets in the frame are respectively detected by the magnetic induction devices corresponding to the respective positions, the device can report the information. The magnetic sensing device determines which positions of the miniature electromagnets are attracted, thereby determining that the shared display device is located at a specific relative position of the main display device. When the magnetic induction devices of the electromagnets R01 to R07 corresponding to FIG. 4 can detect that the magnetic force or the magnetic flux is maximum, the electromagnets L01 to L07 correspond to the positions of the electromagnets R01 to R07, respectively, so as to be determined according to the determined The position of the fit is determined to determine the playback of the extended image portion. For this example, it is detected that the fit height is exactly the same as the height of the shared display device.
又如图 6所示, 两显示设备贴合后, 才 据磁感应装置检测出贴合 部分后(贴合部分磁力或磁通为最大) , 则共享显示设备根据该贴合 部分确定出高度为该贴合部分高度对应的播放窗口, 即图 6共享显示 设备的屏幕虚线内构成的部分是用于播放扩展图像部分的播放窗口, 从而, 虽然两个显示设备贴合后, 呈非矩形, 但整体播放的画面 (即 主画面和扩展图像部分所组合的画面) 仍旧是矩形画面。 不难理解, 播放扩展图像时, 应保持原图像纵横比例, 且播放窗口一边如上贴近 屏幕边缘。 As shown in FIG. 6, after the two display devices are attached, after the magnetic sensing device detects the bonding portion (the magnetic or magnetic flux of the bonding portion is maximum), the shared display device determines the height according to the bonding portion. The playing window corresponding to the height of the fitting portion, that is, the portion formed by the dotted line of the screen of the shared display device of FIG. 6 is a playing window for playing the extended image portion, so that although the two display devices are non-rectangular after being attached, the whole The played picture (that is, the picture combined with the main picture and the extended picture part) is still a rectangular picture. It is not difficult to understand that when playing an extended image, the aspect ratio of the original image should be maintained, and the side of the playback window should be close to the edge of the screen as above.
又如图 5所示, 由上述步骤 S40分别确定出发送给第一、 二共享 显示设备的数据后, 第一、 二共享显示设备检测出相贴合高度和恰与 主显示设备高度相同, 从而使用相应播放区域播放相应的扩展图像部 分。 As shown in FIG. 5, after the data sent to the first and second shared display devices is determined by the above step S40, the first and second shared display devices detect the matching height and the height of the main display device, thereby Use the corresponding playback area to play the corresponding extended image portion.
又如图 7所示,确定出第一、二共享显示设备贴合部分的位置后, 则第一、二共享显示设备由分别确定出的贴合部分高度分别播放各自 所接收的所述扩展图像。 As shown in FIG. 7 , after determining the positions of the first and second shared display device bonding portions, the first and second shared display devices respectively play the respective extended images received by the respectively determined matching portion heights. .
其中, 上述主显示设备与共享显示设备的近距离定位的磁感应装 置用于检测两显示设备的位置, 另外, 上述磁感应装置可选择近距离 无线通信 ( NFC , Near Field Communication ) 芯片。 The magnetic induction device for closely positioning the main display device and the shared display device is configured to detect the positions of the two display devices, and the magnetic induction device may select a Near Field Communication (NFC) chip.
此外, 检测两显示设备的位置也可选择超声波定位, 插槽定位, 或红外检测定位等。其中,所述插槽定位通过金手指或触发开关实现。 其中, 通过插槽定位可使主显示设备与共享显示设备屏幕的边框相贴 合, 实现无缝连接且固定牢靠。 In addition, the position of the two display devices can be selected to select ultrasonic positioning, slot positioning, or infrared detection positioning. Wherein, the slot positioning is implemented by a gold finger or a trigger switch. The slot positioning allows the main display device to be attached to the border of the shared display device screen to achieve seamless connection and secure positioning.
另外, 上述提高位置检测的准确性的方法, 还可以采用图像处理 的方式实现, 即由摄像头采集包含主显示设备与共享显示设备的图 像, 图像分析判断主显示设备与共享显示设备的位置。
步骤 S40: 主显示设备依据共享显示设备的方向、 位置以及属性 参数将图像进行扩展和分割, 并对图像扩展部分进行编码后依据共享 显示设备的方向和位置发送至该共享显示设备, 由主显示设备与共享 显示设备进行分屏显示。 In addition, the method for improving the accuracy of the position detection may also be implemented by using an image processing method, that is, an image including the main display device and the shared display device is captured by the camera, and the image analysis determines the position of the main display device and the shared display device.
