Indoor Unmarked Augmented Reality Furniture System

In recent years,the boom in the real estate market has led to the rapid development of the furniture industry.Because there is no intuitive experience,the furniture did not achieve the desired results when it arrives at home.There also will be problems such as the size need to be measured in advance.Sometimes it's not compatible with other furniture.With the development of augmented reality technology,the above problems can be solved perfectly.Augmented Reality is a technology that integrates real-world and virtual-world information.Virtual information and the real world are cleverly fused,and the computer-generated text,image model,music and other information are integrated with the real world.The two kinds of information complement each other to enhance the real world.At the same time,users can interact with virtual objects through action,gesture,voice,eye movement,body feeling and other ways to get sensory experience that is not available in the real world.Unmarked AR furniture system refers to the application of unmarked augmented reality technology in the field of furniture.By placing the virtual furniture model in the indoor environment,the users could verify whether the furniture placement meets the size requirements and aesthetics.This system could further improve the user's shopping experience.This paper presents an unmarked AR furniture system which takes density clustering as the "tie" of virtual and real integration module.It can effectively get rid of the limitation of traditional artificial markers,and integrate virtual furniture and real indoor environment seamlessly.The contents of the study are as follows:1.Determining the display position of the virtual object when there is no marker.At present,the mainstream uses calibrators to determine the coordinates of virtual objects,but this can lead to problems such as pre-design markers,placement markers and occlusion.In this paper,DBSCAN density clustering algorithm is used to classify and select indoor feature points,and the display plane is established by using the selected feature points,so as to get rid of the limitation of calibration objects.2.Virtual objects must be tracked in real time,3D reconstruction technology is used to track and register virtual objects when there is no calibration object.Combined with computer graphics technology,3D Max is used to build the virtual furniture model,and Open GL is used to display the virtual furniture model.3.In order to verify the feasibility of this paper,an indoor furniture system combining DBSCAN and AR technology was designed.at the same time,the performance is optimized to improve the running efficiency.Comparing with the popular augmented reality algorithm,the system in this paper has the characteristics of virtual reality fusion,good human-computer interaction and no need to set the calibration object in advance,which has good practical value.
