| Rely on the project of of Seismic Acquisition System Key Module SoftwareResearch and Development.In-depth analysis of seismic acquisition3D observingsystem research, based on the seismic acquisition areas for complex surfaceconditions based on how the presence of3D observation system design, optimizationand other problems, proposed seismic acquisition survey design methods based on3DGIS, and in the northeastern Sichuan for3D observation system case study.The resultsobtained are as follows:â‘ For the complex surface conditions on the assumption that surface conditionslevel of seismic acquisition3D survey design does not meet the requirements of theconstruction design problem, proposed a seismic acquisition survey design based on3D GIS terrain visualization technology, and achieved good results;â‘¡For the seismic acquisition for the current domestic and international datashow that3D visualization system efficiency is not high, lack of perspective view ofthe level of detail issues, using data paging management and display, solve theproblem of the original data visualization system efficiency is not high;â‘¢For the original seismic acquisition3D observation system variable means asingle view problem,varied based on3D GIS to solve3D seismic acquisitionobservation system variable concept means a single issues;â‘£For the original seismic acquisition3D observation system supports onlyWindows platform, proposed based on Qt and OSG cross-platform graphics and3Dengine technology, making seismic acquisition observation system to support multipleoperating systems (such as Windows, Linux etc.).In the northeastern Sichuan dimensional seismic acquisition survey design on theapplication results show that3D GIS visualization technology, making the designmore scientific seismic acquisition will help improve surface conditions in complex3D observation system accuracy, thereby reducing construction costs. |
