Research On Image Mosaic Method Based On Homography Matrix

The Image Mosaic Technology solves the problem that high resolution cannot coexist with a large scene which is caused by the limitation of the imaging equipment.Therefore,Image Mosaic Technology becomes an important research content in the field of computer vision,its output cover the entire mosaic scene information and panoramic image with both high resolution and wide viewing angle.This technology has been widely used in the field of virtual reality,aviation,remote sensing,biological image processing and military.Although its basic theory has been improved.There are still some problems in the traditional Image mosaic technology in some specific situations,because of the complex environment.It cannot get the best result,also reduce the quality of the panoramic image.So this article studying on the Image Mosaic Technology based on the questions above.The research content of this object has three following aspects:1.In-depth studying and analysis of the basic concepts and related methods of the traditional panoramic Image Mosaic Technology.Specifically introduced the basic theoretical knowledge of image acquisition,image preprocessing techniques,image registration methods,image transformation and image fusion.Combining with the research points of the paper,determined the most suitable method for this paper in each process,and established a complete panoramic image mosaic method on the basis of the method.2.Introduced an image mosaic method based on homography matrix which solved the phenomenon of distortion and deformation after image mosaic.First,this method uses the homography matrix transformation model to roughly align the frame of the target image and the image to be registered.Then use the image fusion method to synthesize a large scene image with no distortion and good mosaic effect.3.Proposed an image mosaic based on homography matrix and content protection deformation.It effectively on solving the problem of different brightness caused by the intensity light,and changed image content after the mosaic.This method chooses the homography matrix model to align the frames of the input image,and evaluates the best alignment performance.The problem of content changes when the images are stitched is processed by the content protection deformation method to achieve the best effect of image mosaic.
