Description
Technical field
The present invention relates to geologic model display technique field, be specially a kind of image panorama methods of exhibiting based on internet.
Background technology
At present, along with the arrival of the network media, Internet technology ranks among traditional media gradually, and the position occupied wherein is progressively expanding.Web, as the new stage of development of the network media, brings new opportunity to develop to the network media.Web utilizes collective wisdom, sets up the network that a Global interactive is shared.Effectively make use of the data management on network user's collective wisdom and algorithm, anyone can be participated in the middle of network.In the web network platform, by AJAX technology, use the mode of multidimensional, by information integration together, person easy to use goes management and calls.In an AJAX architectural framework, data are always in a kind of state of flowing, the state of namely this flowing, are that originally dull web page contents is lived.Web provides better Consumer's Experience, build Web framework, utilize WSGI (Web service gateway interface) and AJAX (asynchronous JavaScript and XML), easily use and learn, very flexible, and can dynamic load and do not need to restart server service (this greatly reduces the development& testing time).Ajax is current most widely used RIA, and its full name is " AsynchronousJavaScriptandXML " (asynchronous JavaScript and XML), is a kind of web development technologies creating interaction network page application.Ajax is not new technology, and it is the fusion to a series of old technology in the past, but the rise of Ajax, bring huge change and far-reaching influence to traditional internet, applications, the development for internet is filled with new strength.
Panorama display systems comprises panoramic view and panorama system analyzes two parts.Panoramic view is a kind of important scene method for expressing in virtual reality and computer vision, it refers in fixing viewpoint, the image views of 180 ° and horizontal direction 360 ° in the vertical direction, simple form can be 360 ° of views [1] on fixing view plane.Systematic analysis utilizes real panoramic picture as storage mode, improves the loading velocity of virtual system scenic picture, provides new opportunity for building virtual field geology infosystem.Panorama display systems can make user freely walk about in scene, and can the scenes of 360 ° of any viewing all directions, it obtains completely real scene by outdoor scene collection, what user saw is all real scene, instead of Dummy modeling, in addition, map is combined the sense of reality bringing 3D modeling and cannot realize with the interaction of reality scene.Many hot spot technologies that panorama display systems provides, can allow user while the completely real scene of acquisition, inquire about and watch the various information of panoramic picture position more easily.
The visuality of existing geology Information System is poor, and data mainly carry out storing and showing in the mode of word and picture.Virtual reality display technology is the comprehensive information technology that development in recent years one of getting up is brand-new, this technology utilizes hardware device and the Software tool of various advanced person, design rational hardware, software and interactive interface, user can be observed and handle virtual world by interactively, and its essential characteristic is real-time, feeling of immersion, interactivity and imagination.At present, virtual reality technology is own through obtaining preliminary application at numerous areas such as Aero-Space, military training, Machine Design, visualization in scientific computing, 3D video display, such as, along with " the proposition of digital earth theory; virtual reality technology has had certain development at geology, three-dimensional geological modeling, visualization of spatial information etc.Realize virtual reality and mainly contain two kinds of methods: one is the method for drawing based on geometry, also the method (Model-BasedMethod) based on model is called, two is the method (Image-BasedRendering based on image, be called for short IBR), at present, the method of drawing based on geometry has had a lot of application, the application of virtual reality in ground field also all realizes based on geometry rendering technique, the method is owing to relating to complicated Geometric Modeling process, if issued by web, its real-time cannot ensure.And based on the rendering technique of panoramic picture, owing to utilizing real panoramic picture as storage mode, improve the loading velocity of virtual system scenic picture, providing new opportunity for building virtual field geology infosystem.Panoramic virtual reality technology can make user freely walk about in scene, and can the scenes of 360 ° of any viewing all directions, it obtains completely real scene by outdoor scene collection, what user saw is all real scene, instead of Dummy modeling, in addition, map is combined the sense of reality bringing 3D modeling and cannot realize with the interaction of reality scene.If this technology is applied in field geology data sharing, not only greatly can strengthens the visuality of geologic data, and operand can be reduced to a certain extent, the real time problems brought when improvement system is issued by web.
Existing geological information shared system interactivity is poor.Along with the arrival in Web epoch, Consumer's Experience obtains brand-new concern.The part of Consumer's Experience is exactly provide information with user interactions and for user in a novel way.Traditional geology Information System is almost blank out in interactivity.Live-action panorama is applied to GIS field by existing example both at home and abroad, not only increases the visuality of data, and enhances the interactivity of website.In May, 2007, three-dimensional live is innovatively combined with electronic chart by the streetviewmap that Google releases, live-action map search service is provided, in the live-action map of Google, building in reality and road have been not only Points And lines abstract on map, but on the spot in person, lifelike 360 ° of outdoor scenes are experienced; Zheng Jiangyu route panorama composition road net also incorporates existing GIS, have studied the scanning system obtaining streetscape, one drive is scanned completely, and information retrieval is carried out to route panorama, can transmit in real time on the internet, and in large regions, make continuous print visual navigation, by the scenery of simultaneous display map and both sides on the way, the spatial perception improving viewer is experienced; 2006, first virtual panoramic map web site " city " domestic was by the independent research success of Jie Tu software company, and this application allows user original place 360o to look around.In April, 2008, " city " is located and is extended in " outdoor scene city " from " live-action map ", take live-action map as entry, introduce the concept in real " city ", businessman's indoor setting is extended to from street outdoor scene, being merged by the elements such as three-dimensional live, electronic chart, life information, ecommerce, is the numerous netizens localized life information search service that to provide with " outdoor scene " be characteristic.If this technology can be applied to geological information shared system, greatly will strengthen the interaction of existing geological information shared system, promote Consumer's Experience.In fact, make full use of image carry out geological research receive very early people pay close attention to, within 1999, international mathematics geology federation has just held GeoVision conference, different geologic image is emphasized in this meeting, the great function that such as remote sensing, MIcrosope image and other types image play in geological research.
Due to panoramic picture, to have resolution high, the feature strong to the expressive force of actual environment, and geological research mainly carries out survey of territorial resources and geological research by geological observation, panoramic picture meets the feature of geological research completely, and therefore panoramic picture must become the basic data of geological research.Bibliographical information at present about this aspect is little, and domestic research mainly concentrates on the GEOLOGICAL APPLICATION of remote sensing images, carries out research work also not relevant in geological research in collection and application panoramic picture.
That field geology information is also in dispersion substantially, non-dynamic management status, greatly constrains giving full play to of the economic results in society of geological information resource.Being stored from geological informations such as the images that field acquisition obtains by webserver unification, managed is realize one of shared optimal selection of geologic data, but the information category involved by geological information is many, content is complicated, contain much information, if will be issued by Internet, huge network traffic data must be brought, in addition existing network limited bandwidth, the wait phenomenon of user will be particularly outstanding.The speed promoting server and network simply is not only unrealistic but also uneconomical.No matter adopt CGI (CommonGatewayInterfac), WebAPI, ActiveX technology, or ASP (ActiveServerPages) technology, all higher to the requirement of server, the all instructions sent due to user have finally all been come by Server, user side is actually the effect playing a graphic terminal, over-burden to cause server end, and require that the hardware speed of server end is fast, memory size is large.When number of users is many, easily forms bottleneck at server end, and then affect the efficiency of whole system.The Web technology occurred in recent years is address this problem to provide new opportunity, the map web site of sing on web technology releases one after another, along with some major companies in the world and research institution drop into increasing strength exploitation Web technology, Web technology is progressively tending towards ripe.RIA is one of core technology of Web, and it is just in order to fill up a kind of brand-new Web application solution designed by " wide gap " between server end and client.It combines the spread scope characteristic that is wide and that easily propagate of the advantage that reaction is fast, interactivity is strong of multipad and web application, simplify and improve the user interactions of web application.Like this, the application program of exploitation can provide abundanter, have more the Consumer's Experience of interactivity and response.It is contemplated that, if RIA is applied to geological information share field, existing geology Information System will lower the requirement to everyway such as exploitation workload, the network bandwidth, computer hardware etc., the networking of geology Information System will inevitably be pushed to a new height.
