Problems solved by technology

Although this method is simple, it does not consider the parallax problem of images collected from different viewpoints. The direct result is that objects in the overlapping area of ​​the two images before merging will appear blurred or ghosted in the merged image.

Embodiment Construction

[0039] For convenience and brevity of description, the method in the embodiment of the present invention takes the merging process of two images as an example. Obviously, the method in the embodiment of the present invention can also be applied to an image fusion system that combines multiple images, and can also be applied to Image fusion system in the video field.

[0040] It should be understood that, in general, the images to be merged may be acquired by a camera array or other image acquisition devices. For example, the two images to be merged in the embodiment of the present invention may be two adjacent ones in the camera array. Two images captured by the camera in the same scene. The images to be merged can be acquired from different viewpoints, that is, different angles. Since these images are collected from different viewpoints, when the images are merged, the overlapping areas of the images will be blurred or ghosted due to parallax. Parallax refers to the difference...

Abstract

The embodiments of the invention disclose an image merging method and apparatus. The method includes the following steps: acquiring two images to be merged, the two images have an overlapped region which is divided into at least two candidate merging regions; based on light stream vector between the two images, determining the light stream vector mapping difference corresponding to each candidate merging region of the two candidate merging regions; on the basis of the light stream vector mapping difference corresponding to each one of the at least two respective candidate merging regions, selecting an object merging region of the two images from the at least two candidate merging regions; and merging the two images in the object merging region so as to obtain a merged image of the two images. According to the embodiments of the invention, the image merging method and apparatus can reduce fuzziness or double images caused by optical parallax.

Description

Technical field [0001] The present invention relates to the field of image processing, and in particular to a method and device for merging images. Background technique [0002] With the development of the electronic information industry and social needs, various image acquisition devices and large-size displays have quickly entered people's daily lives. The ensuing question is how to obtain wide-view, high-resolution image or video data. For example, the panoramic shooting of daily life images, the merging of satellite images and aerial images, etc., all need to seamlessly stitch together images taken from different viewpoints and merge them into a wide-field, high-resolution panoramic stitched image. In the prior art, ordinary camera arrays are generally used to collect a set of low-resolution or small-view images with overlapping areas, and then merge the images from multiple viewpoints, and combine them into a new high-resolution, wide-view image through splicing and fusion....
