Research And Implementation Of 3D Registration Technology Based On Augmented Reality

Augmented reality technology is a frontier research branch of virtual reality technology.Augmented reality technology combines the 2D and 3D virtual objects into the real scene,and build a virtual world and real world fusion space.Augmented reality technology has been gradually applied to every aspect of daily life,and begins to change people's style of life.In recent years,augmented reality technology is becoming more and more widely used in education.The interactive book is one of the representatives.With the help of smart phones,it combines the characteristics of the traditional paper-based books and digital information,and it can bring readers a multidimensional interaction and wonderful experience of combining virtual and real world.This paper focuses on the problem of 3D registration time delay and image recognition is not good enough in the system.Firstly,analyzes the key technologies of augmented reality.Then,introduces the feature detection algorithm and feature points matching algorithm in 3D registration in detail,and proposes an optimized algorithm to solve the existing problems.The optimized algorithm improves the robustness and reduces the time consumption of the algorithm.Finally,designs and implements an augmented reality interactive book system based on the optimized algorithm.1)Firstly,this paper expounds the technical framework of augmented reality,and analyzes the key technologies of augmented reality such as display,3D registration and computer graphics technology.2)Secondly,in order to further enhance the real-time and robustness of feature detection and feature matching algorithms in 3D registration,a SURF-ORB feature detection algorithm based on SURF and ORB is proposed.This algorithm has the characteristics of strong adaptability and high precision.In the feature matching stage,the Hamming distance is used to match the feature points,and the RANSAC algorithm is used to eliminate false match.3)Finally,this paper analyzes the development pattern and development prospect of the augmented reality technology in the education industry,and designs an augmented reality interactive book system for teaching.
