Embodiment Construction

[0042] In order to solve the problems existing in the prior art, the present invention can respectively obtain the picture taken by the reference camera as the reference picture and the picture taken by the target camera as the reference picture, and set the first prediction overlapping area and the second prediction overlap area on the reference picture and the reference picture respectively. 2. Predicted overlapping areas: judging whether the first predicted overlapping area and the second predicted overlapping area completely overlap; if they do not completely overlap, determine the adjustment direction of the target camera according to the actual overlapping situation. Therefore, the stitching effect can be improved, the adjustment process can be simplified, the calibration and adjustment times can be reduced, the waste of manpower and material resources can be avoided, and the image stitching speed of the camera can be improved.

[0043] Please refer to figure 1 , is a pr...

Abstract

The invention provides a method and a device for quickly splicing camera images. The method comprises steps: an image photographed by a standard camera is acquired as a standard image, and an image photographed by a target camera is acquired as a reference image; according to the position relationship between the standard camera and the target camera, a first predicted overlapped area is set on the standard image, and a second predicted overlapped area is set on the reference image; whether the first predicted overlapped area and the second predicted overlapped area are overlapped completely is judged; and when the first predicted overlapped area and the second predicted overlapped area are not overlapped completely, according to the actual overlapped condition between the first predicted overlapped area and the second predicted overlapped area, the adjustment direction of the target camera is determined. Thus, the splicing effects can be improved, the adjustment process is simplified, the adjustment times are reduced, and waste of manpower and material resources is avoided.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a method and device for quickly splicing camera images. Background technique [0002] At present, when using the image stitching business of surveillance cameras, the ideal stitching effect is often not achieved due to the inappropriate placement angle or position of the camera used for image stitching. Therefore, it is necessary to adjust the camera according to the on-site guidance of professionals in the later stage. . Since the camera is usually arranged at a relatively high position such as the roof of a building or the top of a pole, it is very difficult for construction personnel to adjust the position of the camera. And because cumbersome calibration configuration is required to realize the image stitching business, unskilled business operators may not be able to accurately select the calibration points, resulting in extremely poor image effects after stitchin...
