Embodiment Construction

[0030] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0031] For example, an image acquisition device such as a panoramic camera can simultaneously capture multiple images with overlapping areas for a certain scene point, and stitch together a series of image processing methods to obtain a 360-degree omnidirectional real-scene image. Traditional splicing methods can be divided into dynamic splicing and static splicing. Among th...

Abstract

The embodiment of the invention discloses an image stitching method and an image stitching system. The method comprises the following steps: acquiring a plurality of images corresponding to a plurality of scene points through a plurality of sets of image acquisition equipment respectively, wherein the images corresponding to each scene point comprise a reference image and an image to be stitched, and the reference image and the image to be stitched have an overlapped region; carrying out first remapping on the reference image and the image to be stitched respectively; extracting a rough matching characteristic point pair between the remapped reference image and the remapped image to be stitched; acquiring a fine matching characteristic point pair from the rough matching characteristic point pair by utilizing second remapping; estimating a rotary matrix and a deviation matrix between the plurality of sets of image acquisition equipment by utilizing the fine matching characteristic point pair; and stitching the images corresponding to the scene points respectively according to the rotary matrix and the deviation matrix, so as to obtain a stitched image.

Description

Technical field [0001] The embodiment of the present invention relates to the field of image processing, in particular to an image splicing system and an image splicing method. Background technique [0002] Panoramic images have more and more extensive application scenarios. Traditionally, multiple images collected by multiple image acquisition devices need to be stitched together to form a panoramic image. The usual stitching method includes selecting a specific scene point from the collected images, extracting image features for multiple images corresponding to the scene point, and using the extracted image features to perform image registration and image fusion steps, and finally obtain a panoramic image . The traditional splicing method corrects the internal and external parameters of multiple acquisition devices by extracting the feature points of the overlapping part of the image, and stores the data in a template for remapping the image and then fusing it into a panorami...
