Abstract

The invention discloses an image splicing and fusing method and system. The method comprises the following steps: acquiring an image to be spliced; establishing an image scale space to obtain an imageof each image in m different scale spaces; solving feature points of the image in all scale spaces, and solving an optimal feature point through a non-maximum suppression method; solving the direction of the optimal feature point; establishing a feature descriptor, and performing feature point matching by utilizing the feature descriptor; acquiring an image registration mapping matrix, and completing registration of the two images; and after the registration of the two images is completed, fusing the overlapping regions of the two images to complete image splicing. The feature point solving method and the feature point descriptor solving method are high in speed, small in calculated amount, good in robustness and insensitive to geometric deformation. The image registration method is highin precision, high in reliability and high in anti-interference performance. Based on wavelet fusion, two spliced images can be better transited, information is not lost, and detail information is restored to the maximum extent.

Description

Technical field [0001] The invention belongs to the technical field of image processing, and relates to an image mosaic fusion method and system. Background technique [0002] Image stitching refers to a series of images with overlapping parts, through finding feature points and matching feature points, the final image is fused into a large high-resolution image. It is currently used in many fields. The following is an example of capsule endoscopy . The capsule endoscope is a wireless endoscope. It is composed of a miniature camera, a digital processing system, and a wireless transceiver system. After the subject swallows the capsule endoscope, it can wirelessly transmit the image of the subject’s digestive tract to the outside of the body. Device. Compared with the insertion type gastrointestinal endoscopy, the biggest advantage of the capsule endoscopy is that it is painless, non-invasive, safe and convenient, especially for the examination of the small intestine. The capsul...
