Description

Technical Field

[0001] The present invention relates to the technical field of projectors, and in particular to a projector with a fusion function. Background Art

[0002] In the current industry, large-scale projection display fusion solutions usually use an independent fusion box and a projector. The video data needs to be processed by the fusion box and then transmitted to the projector via an HDMI cable to display the picture. However, as the display area continues to expand, the number of fusion devices and projection devices increases accordingly, which brings great troubles to the installation and construction. The numerous external devices not only increase the failure rate, but also make the maintenance work extremely cumbersome. The existing technical solutions can no longer meet the market demand. Therefore, it is necessary to design a projector with fusion function that simplifies the layout, optimizes the construction and improves the maintainability of the product. Summary of the invention

[0003] The object of the present invention is to provide a projector with a fusion function.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A projector with fusion function, multiple projectors form a display system, and the images projected by each projector form a complete picture, including a fusion module and a display module;

[0006] The fusion module includes a switch and a fusion server, which are connected to each projector through the switch and the network cable. The fusion server receives image or video data from multiple signal sources, performs geometric correction on the data, obtains the position, angle and lens data of each projector through the switch, splices the corrected images or videos into a picture, performs edge fusion on the edges of the spliced ​​images or videos, and finally obtains and adjusts the brightness, color and contrast data of the edges, and fuses them to obtain a seamless and color-consistent complete picture;

[0007] The fused image or video to be displayed is projected through the display module.

[0008] Furthermore, the fusion module is connected to the display module via a built-in display interface.

[0009] Furthermore, each of the projectors is respectively provided with an identification and a number, and is uploaded to the back-end console, and is connected to the fusion server through the back-end console, and sends image or video data, and the back-end console determines the position of the corresponding projector through the identification and number.

[0010] Furthermore, the image or video data is provided with an identification code or a mark. When the back-end console identifies that the display of the current display module is abnormal, the signal path is traced through the identification code or the mark to locate the projector with the abnormal signal.

[0011] After adopting the above technical solution, the present invention has the following advantages compared with the background technology:

[0012] 1. The present invention integrates the fusion function inside the projector, eliminating the need for external fusion equipment, reducing the number of devices and connection complexity, lowering costs, and saving installation space.

[0013] 2. The present invention ensures the high efficiency of signal transmission, reduces signal delay, and improves the real-time and smoothness of display through the internal connection mode of internally integrating multiple modules.

[0014] 3. The present invention reduces the number of devices and the complexity of connection, thereby reducing the points of device failure. Through the corresponding marks or identification codes, once a problem occurs, the corresponding faulty device can be quickly found. Only the projector needs to be maintained, and there is no need to check multiple external devices one by one, saving maintenance time and cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] It should be noted that in the present invention, the terms "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element of the present invention must have a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] Example

[0019] refer to Figure 1 As shown, the present invention discloses a projector with a fusion function, wherein a plurality of projectors form a display system, and images projected by the projectors form a complete picture, including a fusion module and a display module.

[0020] The fusion module includes a switch and a fusion server, which are connected to each projector through the switch and the network cable. The fusion server receives image or video data from multiple signal sources and performs geometric correction on the data. The position, angle and lens data of each projector are obtained through the switch, and the corrected images or videos are spliced ​​into a picture. The edges of the spliced ​​images or videos are edge-fused, and finally the brightness, color and contrast data of the edges are obtained and adjusted to obtain a seamless and color-consistent complete picture. The fusion function is integrated inside the projector, and no external fusion device is required, which reduces the number of devices and connection complexity, reduces costs, and saves installation space.

[0021] The internal connection method of internally integrating multiple modules ensures the high efficiency of signal transmission, reduces signal delay, improves the real-time and smoothness of display, reduces interference factors from external devices, and improves the stability and reliability of the entire projection system.

[0022] The fused image or video to be displayed is projected through the display module, thereby avoiding the complex wiring and installation problems caused by connecting multiple external devices and reducing the difficulty of construction.

[0023] The fusion module is connected to the display module via a built-in display interface.

[0024] Each of the projectors is respectively provided with an identification and a number, and is uploaded to the back-end console, through which it communicates with the fusion server and sends image or video data, and the back-end console determines the position of the corresponding projector through the identification and number.

[0025] The image or video data is provided with an identification code or a mark. When the back-end console identifies that the display of the current display module is abnormal, the signal path is traced through the identification code or the mark to locate the projector with the abnormal signal.

[0026] This embodiment reduces the number of devices and the complexity of connections, thereby reducing the points of device failure. Once a problem occurs, the corresponding faulty device can be quickly found through the corresponding marks or identification codes. Only the projector needs to be maintained, and there is no need to check multiple external devices one by one, saving maintenance time and cost.

[0027] In actual applications, multiple projectors with fusion functions are connected through switches and network cables to form a projection display system. The fusion module of the projector receives images or video signals from multiple signal sources, performs geometric correction on the image of each projector, eliminates image distortion caused by factors such as projector position, angle, lens distortion, etc., and splices multiple corrected images together to form a larger image.

[0028] Then, through advanced algorithms and image processing technology, the position and size of each image are automatically adjusted so that they can be closely spliced ​​together, and the edges of the spliced ​​images are specially processed, that is, edge fusion. The brightness, color and other parameters of the image edges are finely adjusted to ensure that the images projected by different projectors can transition smoothly at the edges. The fused images are output to the projection screen for display, presenting a seamless, color-consistent, ultra-large-size and high-resolution complete picture.

[0029] In this way, the video data is completely transmitted through the network cable to the fusion module and display module inside the projector for processing, and then the display image is directly projected. For example, in the fields of exhibitions or outdoor cultural tourism, the number of projectors can be flexibly arranged according to display requirements to achieve large-size, high-definition fusion display effects. At the same time, during the installation process, only simple network cable connection and projector position adjustment are required, without the need for complicated fusion box installation and debugging.

[0030] When installing the projector, set a clearly visible unique identification and number for each projector, and record its corresponding location information in the control system. Once a problem occurs, the operator can quickly find the corresponding projector based on the identification and number. In addition, a special identification code or mark is added during the video signal transmission process. When a display problem occurs, the source of the projector with abnormal signal can be quickly located by tracing the signal path. Therefore, during maintenance, if a display problem occurs, the specific projector can be quickly located for repair or the fusion module display module can be replaced, which greatly improves maintenance efficiency.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
