Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and unnecessary details and functions for the present invention will be omitted during the description to avoid confusing the understanding of the present invention.

[0022] According to an embodiment of the present invention, a new method for image stitching and video stitching based on foreground object information is proposed. In the process of stitching images, the stitching line is adaptively optimized according to the content of the foreground object; based on the adjusted stitching line, the foreground object and the background area are smoothly blended into the panoramic image.

[0023] In this way, images or videos from different viewing angles can be merged into a large-scale panoramic image or video, and in a dynamic scene, defects in panoramic image quality caused by foreground objects can be eliminated.

Abstract

The invention discloses an image mosaic device and method. The image mosaic process comprises the following steps: adaptively optimizing splicing lines according to the content of a foreground object; and smoothly blending the foreground object and a background area into a panoramic image on the basis of the adjusted splicing lines. Thus, images or videos in different viewpoint and angles can be combined into a large-scale panoramic image or video, and quality defects of the panoramic image caused by the foreground object can be eliminated in the dynamic scene.

Description

technical field [0001] The present invention relates to image splicing, in particular to an image splicing device and method, which are used in still image splicing or video splicing. Background technique [0002] With the development of social needs and the advancement of electronic information technology, people are using various image acquisition devices more and more commonly in their daily life, such as surveillance cameras, digital cameras, digital cameras, network cameras, mobile phone cameras and so on. The popularity of these image acquisition devices has brought convenience to people in terms of life, entertainment and safety, and has also brought new requirements: that is, how people can use the growing digital multimedia information in an effective manner. Image stitching and video stitching technologies provide a technical solution to meet new needs, which can generate clear large-scale panoramic images or videos, and bring people an unobstructed visual experien...
