Research And Implementation Of Visualization System Based On SKYLINE In Shanghai Expo 2010

Visualization command system in shanghai expo 2010 is based on GIS, relying on video surveillance, GPS positioning and other advanced technology, through the visualization conductor management business, comprehensive major matters, the emergency plan and related information on operations, the show, analysis, aided decision-making.It can become a strong command tool of site operation command center.This paper expounded part of typical functions at the visualization command system.including in interaction tecnology of 2-D and 3-D, real-time monitoring remove object and 3d roaming. This system is in combination with user needs and with a thorough investigation and research, finally shows these functions in the application.Two 3d linkage function is realized through each other response mechanism of two-dimensional vector map and 3d GIS, both the combination of mutual response premise is realizing 2-d maps and 3d scene one-to-one mapping between, must establish the only correspondence between coordinate system or corresponding geophysics name one-to-one; Moving target real-time monitoring function is through the GPS to locate a moving target, again through GIS map control of intelligent analysis video monitoring resources around anchor point, thus by optimal Angle and vision for real-time monitoring; 3d roaming is through the Skyline own series software, through the large areas of modeling. Very easy to realize comprehensive, multi-angle roaming browsing, 3d display inquiry, model application, analysis and decision-making functions.This paper studies's meaning is getting the realization method of interaction tecnology of 2-D and 3-D, real-time monitoring remove object and 3-D roaming.It has greatly increased the "visual" function and effect. Meanwhile, the optimization of these three functions provides the help for the scheduling at expo 2010.The research results of this paper can simplify the switching operation of 2-D and 3-D, intelligent search for moving target and real-time monitoring though the surrounding monitor,and also increased browsing effect, become the lightspot for the visualization command in 2010 world expo.
