1、 Augmented reality(Reality Augmented,referred to as AR),is a new technology developed on the basis of virtual reality,also known as mixed reality.Is provided by the computer system information technology increases the users perception of the real world,the application of the virtual information into
2、 the real world,and computer-generated virtual objects,scene or system information superimposed on the real scene,so as to realize the enhancement of reality.AR A perfect AR system includes a number of disciplines,including the technology of system display and positioning technology,virtual reality
3、fusion technology and user interaction technology is the basic support technology to achieve a AR system.Head mounted displayProjection type(display technology)Handheld displayCommon liquid crystal displayDisplay technology of AR systemTracking and positioning technology Due to the perfect combinati
4、on of virtual and real objects,it is necessary to combine the virtual objects into the real world.This process is called registration(Registration).Therefore,tracking and positioning system AR must be capable of detecting the observer location in the scene,from the perspective of the direction of mo
5、vement,even the situation,in order to help the system determine what virtual objects,and in accordance with the observers field of view coordinate reconstruction.Industrial maintenance field This is likely to be applied to enhance the reality of the first industry.The marker can be connected to a sp
6、ecific object that is being constructed,and the augmented reality system can describe the image on it.This is a relatively simple form of augmented reality,because the system only need to know the user relative to the location of the object he saw,and do not have to track the exact physical location
7、 of the person.Tourism domain People in the browse,visit at the same time,through the augmented reality technology will receive through the construction of relevant information,to watch the exhibits related data.Military field Augmented reality systems can provide the army with important information
8、 about the surrounding environment,such as the entrance to the other side of the building,which is a bit like X ray vision.Augmented reality display can also highlight the armys mobile,so that soldiers can be transferred to the enemy can not see the place.Domestic present situationOur country in the
9、 field of AR research started late,research institutions are mainly concentrated in the scientific research units.From the domestic published papers,mainly focused on the system application and registration technology,the study of the problem is relatively simple,involving a relatively narrow face.北
10、京理工大学北京航空航天大学国防大学浙江大学上海大学 Some high-tech companies are by constructing augmented reality platform,to achieve more extensive application form,such as Wikitude and Layar,they have an open SDK,Android,blackberry,let iOS 10 and Web(HTML5,JavaScript and developer support CSS)augmented reality module can
11、create cross platform based on geographic location,image recognition,3D animation.Sounds complicated,in fact,very simple.Whether iPhone,Android or other mobile phone platform,can through the application and a camera to scan the real scene of rich information,you can know about this hotel,the restaur
12、ant can see the score,the official information and so on.Of course,creating a huge database is a time-consuming and laborious thing,but we believe that this application will eventually become a reality.We have recently seen a new concept of application.Samsung recently applied for a game based on Au
13、gmented Reality keyboard technology,from the side also confirms the existence of Samsung smart glasses.This technology allows users to wear glasses to see their own hands on the virtual keyboard,as long as the thumb can be used to complete the text input.Of course,the application of virtual reality
14、on the smart glasses will have some worrying places,such as decentralized our attention or network security risks,so that hackers through this technology to attack users.But we dont have to worry about it for the time being,because people will only use the augmented reality to see things that they are interested in.
