Problems solved by technology
In practical applications, it is often necessary to splicing multiple channels of high-definition video. Taking the splicing of 5-channel 1080P HD video as an example, assuming that the splicing cameras are arranged in order from left to right, and there is an overlapping area of about 20% between the cameras, the splicing result The image resolution of the image is about 8100*1080, and the stitching result far exceeds the resolution limit of the current common hardware display, so the stitching result cannot be displayed at the original resolution

Embodiment Construction
[0011] Concrete implementation of the present invention is as follows:
[0012] (1) Arrange multiple monitors used for display in sequence up, down, left, and right. According to the resolution of the splicing results and the resolution of the monitors, and according to the principle of filling the screen first, the splicing results are segmented and displayed in sequence. On the corresponding screen, realize the multi-screen display of the splicing result;
[0013] (2) Taking the image center of the splicing result as a reference point, realize the zoom control of the splicing result according to the image interpolation algorithm, and update the multi-screen display of the image in real time according to the size of the zoomed image;
[0014] (3) When displaying the splicing result, take the center of the image as the reference point, respond to the mouse movement event after the user presses the left mouse button, and realize the dragging control of the splicing result, and ...

A multi-screen display and control method for video stitching results comprises the following steps: sequentially arranging multiple displays for displaying at top, bottom, left and right, and segmenting the stitching results and sequentially displaying the stitching results on the corresponding screens according to the resolution of the stitching results, the resolution of the displays and the principle of filling the screen with a previous order to achieve the multi-screen display of the stitching results; taking the image center of the stitching results as a reference point, implementing zoom control on the stitching results based on an image interpolation algorithm, and real-timely updating the multi-screen display of the image according to the size of the zoomed image; and when implementing method display on the stitching results, taking the image center as the reference point, responding to the mouse movement event after the user presses the left mouse button to achieve the drag control of the stitching results, and real-timely updating the multi-screen display of the image according to the position of the dragged image.
Description
technical field [0001] The invention relates to the technical field of digital audio and video, in particular to a multi-screen display and control method of video splicing results. Background technique [0002] The implementation process of video stitching is mainly divided into three processes: image registration, image fusion and result display. In practical applications, it is often necessary to splicing multiple channels of high-definition video. Taking the splicing of 5-channel 1080P HD video as an example, assuming that the splicing cameras are arranged in order from left to right, and there is an overlapping area of about 20% between the cameras, the splicing result The image resolution of the image is about 8100*1080, and the stitching result far exceeds the resolution limit of the current common hardware display, so the stitching result cannot be displayed at the original resolution. In addition, due to business needs, it is often necessary to control the splici...
