Embodiment Construction

[0078] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0079] In order to solve the technical problem that those skilled in the art have been trying to solve but have not completely solved, the problem is that video splicing is prone to ghosting when the overlapping area contains moving objects. The invention provides a video splicing method based on dynamic optimal stitching. This method eliminates the ghost phenomenon after video splicing. Such as figure 1 As show...

Abstract

A video stitching method based on a dynamic optimal stitching line belongs to the technical field of video information processing. The method comprises the following steps: S1, calculating the overlap region of spatially adjacent images; S2, separating the foreground and background images of the overlap region; S3, calculating out an optimal initial stitching line; S4, determining whether each pixel on the stitching line of frames in front and behind is a moving pixel through calculation; S5, judging whether to update the optimal stitching line; S61, updating the optimal stitching line, or S62, maintaining the current optimal stitching line; and S7, fusing the images according to the optimal stitching line to get a panoramic image after stitching. The problem that ghosting is likely to occur during video stitching under the condition that the overlap region contains a moving object is solved. A good video image stitching effect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of video information processing, and relates to video splicing technology, in particular to a video splicing method based on a dynamic optimal stitching line. Background technique [0002] Video splicing refers to the technology of splicing multiple image sequences taken by multiple cameras from different perspectives into panoramic video, which is widely used in large-scene surveillance systems and unmanned driving systems. [0003] A core problem of video splicing is how to eliminate ghosting caused by parallax, especially in scenes where the overlapping area contains moving objects. In order to reduce splicing ghosting caused by parallax in video splicing, also known as "ghosting", one type of method is to use advanced image synthesis technology, such as seam cutting (cut seam) method, but when a moving target passes through the stitching line, apply In this kind of method, the moving target will be broken in t...
