Research On Componentization Of Augmented Reality On Mobile Terminals And Related Technologies

In recent years,with the improvement of computing power of mobile devices and the upgrading of data access efficiency of wireless communication technology,augmented reality technology based on mobile terminals has a stable technical support.With the help of the combination of virtual reality and real-time interaction,mobile augmented reality has achieved outstanding performance in many fields,such as life and entertainment,education and health care,travel display,but its application is still limited by the engineering needs.A set of system only adapts to one scene,lacking systematic standards and summary.In addition,in the actual augmented reality target detection stage,there are some problems,such as over fitting recognition,unrecognized,detection time is too long and so on.Based on the augmented reality project,this paper uses the point cloud filtering to remove the outliers in the augmented reality point cloud,and uses the collaborative recognition method to improve the recognition efficiency of the augmented reality system.Then,based on the optimized augmented reality system,this paper summarizes the functional modules and information carriers of augmented reality,and constructs the component library of the mobile augmented reality.This paper mainly consists of three parts.1.Research on the stability of mobile augmented reality system and target detection algorithm,from the aspects of marker recognition,feature point description,world tracking and three-dimensional rendering.Through theoretical research and experimental testing,ARKIT is selected as the basic platform of component library.Innovative point cloud space segmentation,radius filtering simplify invalid point cloud data,realize the efficiency improvement in dense point cloud scene.In addition,a method of collaborative recognition of two-dimensional features and three-dimensional features is proposed to realize the detection of registered objects.2.Research on component content of augmented reality on mobile terminal.Through literature research and engineering practice,a set of augmented reality application components for mobile terminal is summarized.For each component,the preset information of location,posture,material and other components is analyzed.The pre Fab method is used to preprocess the preset body,abstract the data and relationship,and develop the component interface of augmented reality on the mobile terminal to form the component library of augmented reality on the mobile terminal.3.Combined with the above technical basis,experimental results and component library research results,an application example of "memory gymnastics" based on component library model is constructed,which is superior to the native component in development efficiency and user experience.
