Embodiment Construction

[0022] The method of stitching two images is the most studied case in image stitching, and its algorithm can often be extended to multiple image stitching. Therefore, in the following, the traditional image stitching method and the image stitching method of the present invention will be described by taking the stitching of two images as an example.

[0023] The first condition of image stitching is that two images have common image content, that is, the overlapping area. That is to say, part of the content in the two images is part of the content in the same scene. It is precisely because of the existence of overlapping areas that two images can be merged according to the overlapping areas, and finally the two images are stitched into one image. Therefore, the image stitching algorithm is to determine the overlapping area between the two images, and determine the position of the two images in a unified coordinate system according to the position of the overlapping area.

Abstract

The invention provides a method for splicing images and a device thereof. A first image I1 corresponds to a first view point V1, and a second image I2 corresponds to a second view point V2. The splicing method includes: a determining step of selecting a starting point O1 in the first image I1 and a terminal point O2 in the second image I2 to determine a view point transitional area between the first image I1 and the second image I2; a generating step of inserting a pseudo view point transiting from the view point V1 to the view point V2 between the starting point O1 and the terminal point O2, then transforming a pixel in the view point transitional area into a pixel corresponding to the pseudo view point to generate a transitional pixel; and a splicing step of splicing the pixel in the non view point transitional area corresponding to the view point V1 in the first image I1, the transitional pixel, and the pixel in the non view point transitional area corresponding to the view point V2 in the second image I2 to form a spliced image.

Description

technical field [0001] The present invention generally relates to computer vision technology, and more particularly, the present invention relates to methods and devices for image stitching and video stitching. Background technique [0002] The technology of stitching images taken at different angles or positions seamlessly according to their spatial position relationship to form a high-resolution panorama is called image stitching. Image stitching technology is an important field of computer vision research. This technology has a wide range of uses, such as the synthesis of satellite images or aerial images, the establishment of panoramic virtual scenes, photo editing, etc. With the advancement of technology in this field, image stitching has entered people's daily life. For example, in a digital camera, panorama composition has become a function of the digital camera. [0003] Video stitching is a special image stitching technology. The purpose of video stitching is to...
