Abstract


With the development of computer technology , it is increasingly strong requirements for the construction of \But realistic restoration and reconstruction of objects original , inextricably linked with the accurate spatial data , so how to effectively collect data and information is one of the current problems to be solved . In this paper, the current domestic and international situation , design a cost-efficient ground-based visualization environment information acquisition and 3D reconstruction system , focus on solving the problem of space access to information , and access to a number of key technology in the process were analyzed . An effective pseudorange differential characteristics of differential GPS applications . Combined with GPRS communication using UDP , mobile data transmission . This key technology for camera calibration , in view of the application environment of our system , based on virtual panning camera calibration method .
