Description
Technical Field
The utility model relates to the field of image processing, in particular to a system for realizing multi-screen projection picture fusion by utilizing an intelligent display card.
Background
In the field of modern multimedia display, projection technology is widely applied, projectors are standard equipment of modern conference rooms, and in large-scale activities, performances or exhibitions and other occasions, a multi-screen combined display scheme is widely applied, but the problem of picture fusion in the scheme is still a difficult point, the display effect and the impression experience are directly influenced, the existing multi-screen combined display scheme mainly comprises a display wall hard splicing technology and an edge fusion technology, most multi-screen combined display schemes in the market adopt the edge fusion technology, the camera-based correction technology generally adopts a centralized structure, the centralized structure cannot be expanded, the shape and resolution cannot be automatically adjusted, the fault tolerance is poor, the use cost and the technical threshold are greatly increased, various problems exist in the use process, the fussy software and hardware configuration is required to be carried out in the use of the fusion equipment, and the deployment difficulty and time are increased.
In recent years, with the development of computer technology, a video card has become one of the most important devices in a computer, and the function of a smart video card is far from being limited to outputting images. Their computing and information processing capabilities are also continually expanding and increasing. The intelligent display card is utilized to fuse the overlapped pictures projected by the projectors, so that seamless connection of the pictures can be realized more flexibly, and the use of additional fusion equipment is reduced, thereby having great advantages. As shown in fig. 1, the multi-screen projection fusion is to perform edge overlapping on the images projected by a group of projectors, and display a brighter, oversized and ultra-high resolution whole image without gaps through fusion technology, and when two or more projectors are combined to project a single image, the scheme has the disadvantage that an excessively bright area appears due to brightness superposition, so that the brightness of the whole image is consistent, and the overlapping part needs to be processed; in this embodiment, the processing manner of the left projector and the right projector at the overlapping portion of the frames is different, compared with the simple overlapping method, the brightness of the overlapping portion of the left projector in the edge blending technology is linearly attenuated, the brightness of the overlapping portion of the left projector in the right projector is linearly increased, the purpose of the processing manner is to make the brightness of the whole frame completely uniform, and the problems of discontinuous and uneven frames in the simple overlapping method are solved; specifically, the brightness of the overlapping portion on the right side of the left projector needs to be attenuated to counteract the excessive brightness caused by the brightness enhancement of the overlapping portion of the right projector, so that the left projector needs to gradually weaken the light intensity so as to make the brightness of the whole picture smoothly transition; the left overlapping part of the right projector needs to increase brightness to compensate the too low brightness caused by the distortion of the left overlapping part, so that the right projector needs to gradually increase the light intensity to ensure the consistency of the brightness of the whole picture; therefore, the brightness of the whole picture can be consistent through the comprehensive adjustment of the left projector and the right projector, the processing mode can solve the problems of discontinuous and uneven projection pictures, the brightness and the definition of the whole image can be improved, and a more real and lifelike visual effect is presented for users.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 and fig. 2 in combination, an embodiment of the present utility model provides a multi-screen projection screen fusion system based on a smart graphic card, including a projector, a video source, and a projection screen; the number of the projectors is at least two, the projectors are in communication connection with each other and the video sources, and an intelligent display card is arranged in the projectors and used for realizing picture fusion of multi-screen projection.
The video source is a computer device, and is used for providing an input picture for the projector, and the working procedure of the embodiment of the utility model is as follows:
firstly, transmitting the whole image to be projected to the projectors by the video source through an input interface, wherein the projectors are in communication connection with each other and the video source, so that the traditional HDMI input split-screen fusion is supported, and the distributed fusion of pure network cable arrangement is also supported;
the video source controls the intelligent display card to cut the whole image input by the video source into a plurality of small pictures which are adaptive to the number of projectors through DisplayFusion software, and each projector displays the corresponding small picture respectively;
the display card chip is a professional image processing chip i-Chips chip and supports the functions of image geometric correction, edge fusion and color correction; because the projector can only obtain rectangular patterns when being perpendicular to the projection screen, when the projector is inclined to the projection screen, the projected image can generate serious trapezoidal distortion, in the practical application environment, the factors such as the placement position and angle of the projector can cause certain deformation of pictures spliced by the projectors, and at the moment, the trapezoidal distortion of the pictures of the projectors in the multi-screen projection is needed to be solved through geometric correction;
after geometric correction, matching a plurality of projection pictures to obtain non-distorted integral large-screen projection, wherein the boundaries of the pictures are blurred after the geometric correction, and the overlapping parts of adjacent images are not subjected to fade-in and fade-out treatment, so that an over-bright area exists, and therefore, edge fusion is needed, and the brightness, contrast and saturation of each picture are adjusted to obtain a natural, smooth and ghost-free unified large-picture effect;
after correction of the projection overlapping part, the highlight display area of the original overlapping part disappears, but the edge fusion method only eliminates the color difference of the overlapping area, and does not consider the problem of nonuniform color of the whole display picture formed by the color difference among the projectors, so that the picture needs to be subjected to color correction to achieve the uniform color effect of a plurality of pictures;
after the adjustment is completed, the processed picture is output to a projection screen, so that a bright, oversized and ultrahigh-resolution whole picture without gaps can be obtained.
