The display direction is the display direction of the display device. At this time, the direction of the electronic device 20 can be determined by the angle detecting unit 208 in the electronic device 20 to determine the direction information of each of the display devices 11-14. Further, according to the unique pattern displayed by each of the display devices 11 to 14 in the first image, the spatial position information of each of the display devices 11 to 14 is obtained (step S112). After obtaining the direction information and the spatial location information, it can be known which parts of the image should be displayed by the display devices 11~14, and whether the individual display devices need to invert the image and how the image should be segmented near the screen frame. Therefore, the processing unit 204 can calculate a plurality of display parameters corresponding to the plurality of display devices 11 to 14 based on the direction information and the spatial position information of the plurality of display devices 11 to 14 (step S114). The processing unit 204 can perform the above operations by loading the program. For example, in the mobile phone, the application can be installed on the mobile phone to enable the processing unit 204 to have the capability to perform the above steps.

For example, each of the display devices 11-14 can include a processor and an image scaler, and can receive display parameters from the electronic device 20 to know which part of the image to display, such as in an image. The coordinate position range is displayed, and the corresponding area screen is displayed. In an implementation, the example of transmitting the display parameter may include: dividing the image frame by the electronic device 20 and transmitting the image to the display device 11-14, for example, the Miracast wireless display standard transmission based on Wi-Fi Direct connection The display screen or the display devices 11-14 receive a single image source, and the electronic device 20 transmits the displayed block information to each of the display devices 11-14, and the display devices 11~14 divide the image or display device 11~ 14 is connected in series, and the electronic device 20 transmits the split information to the first display device 11. After the first display device 11 obtains the divided screen, the remaining screen information is transmitted to the second display device 12, and then sequentially divided. The screen is transmitted to the connected third display device 13 and the fourth display device 14.

Communication process.

Referring to step S108, FIG. 7 is a schematic diagram showing a unique pattern displayed on each display device according to an embodiment of the invention. Since each display device displays a different pattern, after the first image is captured, different display devices can be clearly identified, and the position of each display device can be recognized by image processing. There are various embodiments for displaying the unique pattern. As shown in FIG. 7, each of the display devices 11 to 18 can display different recognizable patterns. The type and style of the displayed pattern are not limited, and the pattern can occupy the full screen of the display device. This makes it possible to know the range that each of the display devices 11 to 18 can actually display based on the first image captured. One of the embodiments in which each display device displays a unique pattern is to display a solid color screen on the full screen of each display device 11-18, for example, the display device 11 displays full screen red, the display device 12 displays full screen yellow, and the display device 13 displays full screen. Green, display device 14 full screen display blue, etc., Figure 7 shows different diagonal lines shown by display devices 11~18 The bottom of the net can be seen as a different solid color picture.

Since the number of display devices included in the splicing screen display system 1 is large, all the display devices may have doubts that the colors are not easily recognized by the solid color screen, or may be difficult to identify the specific color due to the naturally occurring ambient light source. . Therefore, in another embodiment, the recognizable graphic can be displayed on the solid color screen of at least one of the display devices 11 to 18. The type of the recognizable graphic is not limited, and may be, for example, a simple geometric figure. FIG. 8 is a schematic diagram showing a unique pattern displayed on each display device according to an embodiment of the present invention. In this example, the display devices 11 to 14 display a solid color screen on a full screen, and the display devices 15 to 18 display another on the solid color screen. The recognition pattern is, for example, a triangle, so that only four colors can be used (the same diagonal line bottom indicates the same background color, for example, the display device 15 is the same as the bottom color displayed by the display device 11, and the display device 16 and the display device 13 display the ground color. The same), and eight display devices are identified. In an embodiment, different display devices can also display different recognizable graphics, including, for example, triangles, circles, rectangles, etc., so that the number of identifiable display devices can be increased.

The unique pattern displayed by each display device 11-18 can be determined by the display device 11-18, or in one embodiment, the unique pattern displayed by each display device 11-18 can be determined by the electronic device 20. For example, after performing step S104, the electronic device 20 can obtain the display device identification codes of the display devices 11-18, know how many unique patterns are needed, and can assign the unique patterns displayed by the display devices 11-18, for example, What is the solid color of the color, or what identifiable graphics are included. The electronic device 20 can transmit related information of the determined unique pattern The corresponding display devices 11-18 are transmitted, for example, by wireless communication.

With regard to step S110, FIG. 9 is a schematic diagram of capturing an overall screen combination to generate a first image according to an embodiment of the invention. In the first image, since the display devices 11 to 18 display the unique pattern, the spatial position information of each of the display devices 11 to 18 can be obtained (step S112), and the spatial position information of each of the display devices 11 to 18 includes, for example, the display device. At least one of a display range and a display device vertex coordinate position. As shown in the previous embodiment, the display devices 11 to 18 can display a solid color screen on a full screen. Therefore, by using a filter color block or similar image processing technology, the range of display of each display device can be clearly recognized from the first image and The position of the end point, if there is a gap or overlap between the display devices 11~18, or the display devices 11~18 include screens of different sizes or different shapes, can also be clearly interpreted from the first image. Therefore, by the step of capturing the first image, the position information of each of the display devices 11 to 18 in the space can be obtained, and the boundary of the display range of each of the display devices 11 to 18 can be known, and each display device can be determined. 11~18 image display to be displayed.

With regard to step S114, FIG. 10 is a schematic diagram of calculating display parameters according to an embodiment of the present invention. After the step S106 is performed to obtain the direction information of the display device, the four original endpoints P ₀ to P _{3 of} each display device may be given according to the direction information, respectively corresponding to the lower left corner, the upper left corner, the upper right corner, and the lower right corner of the screen itself, for example, the original The end point P ₀ corresponds to the positioning mark P _C , the original end point P ₁ corresponds to the positioning mark P _A , and the original end point P ₂ corresponds to the positioning mark P _B , as shown in FIG. 10 , the original end point P ₀ and the original The edge between endpoints P ₃ represents the bottom edge of the screen itself (shown in thicker lines). After the spatial position information of the display device is obtained in step S112, the four spatial endpoints of each display device are sequentially designated clockwise from the bottommost vertex to p[0]~p. [3].

According to the above-described correspondence relationship, after the first video is captured, the screen content to be given to each display device can be known, so that corresponding display parameters can be obtained and can be transmitted to each display device to display the corresponding region screen.

According to the splicing screen display method and system of the present invention, only one electronic device is used for scanning or shooting, that is, the direction information and spatial position information of the display device can be obtained, and the image can be correctly displayed on the splicing screen. In addition, since the rotation angle is calculated by the directional bar code, the problem of image reversal can be effectively avoided. Therefore, when splicing the screen, each display device can be arbitrarily placed without restricting the position of the bottom edge even if the rotation of the plurality of display devices Different angles exist, and there are opposite cases. The splicing screen can also display images correctly, simplifying the process of placing the display device. In this way, the problem of screen steering can be solved by the directional bar code, and the gravity sensor can be prevented from being installed inside the display device, thereby reducing the hardware cost.

In addition, by displaying a unique pattern on the full screen, the exact display range of each display device can be effectively grasped. Therefore, even if the sizes of the plurality of display devices are different, or even if they are spaced apart from each other or overlap each other, the photographing can still be grasped. Where the boundary positions that can be actually displayed by each display device are located, and corresponding display parameters are calculated. Therefore, according to the splicing screen display method and system of the present invention, the screen segmentation of the current splicing screen placement mode is automatically completed by the electronic device, and the user not only has a higher degree of freedom in placing the display device, but also after the placement is completed. The operation is simpler and faster.
