Research On Realistic Reappearance Of Image Contours For Real Sense Augmented Reality

Real sense augmented reality is an augmented reality technology that uses real sense images.Real sense images can better represent the reality of objects and apply real sense images to augmented reality.This makes up for the traditional augmented reality technology that uses three-dimensional modeling of virtual objects generated when implanted lack of realism,rendering a long time,large amount of computation.However,there are many problems that need to be researched in how to integrate the real images into the real environment.Therefore,the thesis has been studied on the realistic reproduction of the registration contour in the augmented reality environment.The research contents of this thesis are as follows:(1)Using the self-designed experiment platform to collect the real images of objects needed in augmented reality,a real sense image database was established.(2)Proposed the image matting technology commonly used trimap generation algorithm.Based on the background difference method and saliency detection algorithm,the trimap was generated for the original image,and the effects of the two algorithms were compared.Finally,trimap generation algorithm based on saliency detection is chosen as the trimap generation algorithm in this thesis.The algorithm can better achieve the generation of trimap.(3)Proposed an algorithm based on shared sampling about realistic contour of the image.This thesis analyzes the algorithm of image matting based on shared sampling in detail,and realizes the extraction of the target object in the real image by this algorithm.According to the principle of the algorithm,the basis of the algorithm of image contour reality fusion is proposed.Realizing the realistic contour of the image when the target object is implanted into the real environment by shared sample image contour reality fusion algorithm.(4)All the algorithms are integrated to realize the realistic rendering of the contour realistic scene.In summary,the thesis through the establishment of real image database,the use of the proposed trimap generation algorithm to generate the trimap of real image,the use of the generated trimap with the image matting algorithm to accurately extract the target object,and then the target object using the shared sampling image contour realistic fusion algorithms for image contour fusion,and finally realizes realistic rendering of image contour for real-scene augmented reality system.
