Design And Implementation Of Virtual Home Furnishing Layout System Based On Marker-less

Augmented reality technology can fuse virtual information with real scenes and give people immersive feelings.In the field of home decoration,physical furniture can be converted into models and the placement of furniture can be completed through the screen by using augmented reality technology.This approach improves the efficiency of home decoration and enables users to feel the true home furnishing process.At present,there are few augmented reality applications for home furnishings in the market,and the applications are generally applied by the furniture companies.There is a problem of low degree of fusion and poor stability in these applications.As the core of augmented reality technology,tracking registration algorithm determines the final mixing effect.The commonly used tracking registration algorithm is time-consuming and causes the accuracy to decrease due to image blurring during the movement.Based on this,this paper studies the tracking registration algorithm,applies the improved algorithm to the augmented reality system,and designs and implements a non-marker-based virtual home layout system.First of all,this thesis investigates the development status of augmented reality technology at home and abroad,and analyzes its application fields.Through the analysis of various tracking registration methods,combined with the application scenario of home layout,the overall system design was designed.According to requirements,the system is divided into three layers,including user layer,business logic layer,and network layer.The key tracking matching module and virtual reality fusion module in augmented reality are processed at the business logic layer.Then,this thesis analyzes and studies the tracking registration algorithm.In order to solve the problem of image edge information loss in the establishment of linear scale space,KAZE algorithm is analyzed in this thesis.Through the improvement of the algorithm,it solves the complex and time-consuming problems of the algorithm.At the same time,corresponding optimizations are made for mobile devices to improve the operating efficiency of the software.Through the research of camera posture calculation method,the accurate fusion of virtual information and real scenes is achieved.Finally,the design and implementation of various parts of the system.A detailed description of the platform construction was given.The detailed design and implementation of various functional modules were carried out,including the tracking and matching module,the virtual reality integration module,the user management module,the community sharing module,the interactive communication module and the data storage module.In order to verify the performance of the home furnishing system,a reasonable test plan was designed and the system was tested and analyzed.The test results show that the work done in this thesis satisfies the expected requirements.
