Research On Tracking Registration Technology Based On Augmented Reality

As a research hotspot in the field of computer vision in recent years,augmented reality technology has attracted more and more attention from society and is applied in many fields.The so-called augmented reality is to accurately overlay computer-generated virtual information in real scenes,which enhances people's perception of the real world.Among them,the tracking and registration technology of augmented reality directly affects the accuracy and real-time of the fusion of reality and reality.Therefore,improving the accuracy of tracking and registration is an important factor for the consideration of augmented reality technology.In the 5,000-year-long history of China,Majiayao painted pottery in Gansu is an indispensable part of witnessing the late Neolithic culture in the upper Yellow River.However,the traditional way of understanding the Majiayao painted pottery can only be viewed through the glass in the museum,which is simple and tedious and provides less information.The use of augmented reality technology in Majiayao painted pottery culture can make Majiayao painted pottery presentation more diversified,allowing users to understand the Majiayao painted pottery culture in more detail and vividly.The main research contents of this article are as follows:(1)Investigate feature detection and matching.Firstly,the traditional ORB algorithm does not solve the problem of scale invariance.In the feature detection process,the image pyramid is constructed so that it has scale invariance.Second,when the features are matched,the matching points are purified using the RANSAC algorithm,and no matching points are filtered.Ensure the accuracy and robustness of the algorithm.(2)The problem of target tracking registration was studied.Aiming at the deficiency of the median stream algorithm in the TLD algorithm tracking module,which leads to false positives during the target tracking process,the KLD algorithm with better speed and accuracy in the target tracking process is used instead of the TLD algorithm tracking module to improve It improves the accuracy and robustness of target tracking.(3)From the perspective of promoting the culture of Majiayao pottery,combined with augmented reality technology,the design and implementation of the Majiayao pottery's augmented reality system.The Majiayao pottery was identified through the camera.After the recognition,the 3D Virtual information such as models,videos,and audio are accurately superimposed in real scenes,and users can interact with it to increase the interest and spread the Majiayao pottery culture.
