Image stitching method and apparatus

Abstract

The embodiment of the invention provides an image stitching method and apparatus. The method includes the following steps: obtaining multiple frames of images to be stitched; determining moving targets of the multiple frames of images to be stitched and background areas except the moving targets; determining background models of all the images to be stitched on the basis of each background area; calculating a proportion value of an overlapped area of every two adjacent moving targets, and selecting the moving targets whose proportion value of the overlapped area meets a preset condition as target moving areas; and enabling all the target moving areas and the background models to be stitched into a target image. The stitched image obtained through the embodiment can clearly present a full moving view of the moving targets, and the image stitching effect and the actual user experience are improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image splicing method and device. Background technique [0002] With the popularization of mobile terminal cameras, people are more and more fond of sharing pictures on social networking sites to increase fun. Various camera functions of mobile terminal cameras emerge in an endless stream. Sometimes users want to use a picture to record the process of an action or instant, such as figure 1 as shown, figure 1 Recorded the process of athletes skiing, in order to get how figure 1 The picture shown requires the use of image stitching technology. [0003] As an important branch of image processing technology, image mosaic technology refers to the matching and alignment of a series of multiple images with partial overlapping areas captured by the camera on the same scene, according to the characteristics of different images, using different processing algorithms....

Problems solved by technology

[0005] When the existing image stitching technology stitches these images taken in the same scene into one picture, when the object moves slowly, the overlap between adjacent images is relatively large, and the object displayed in the image is blurred. When selecting the method, although the obtained spliced ​​image can record the whole picture of the moving target and expand the viewing angle of the picture, the overlapping parts between multiple frames of moving targets will also appear on the picture, and it is impossible to get a clear splicing of the moving target image, poor stitching of images
