[Abstract]:Based on the project of "key module R & D of seismic acquisition software system", the research on the design of seismic acquisition and observation system based on 3D GIS terrain visualization is carried out. The design method of the observation system, optimization and so on, the design method of the seismic acquisition and observation system based on the 3D GIS is put forward, and the three dimensional observation system is carried out in the northeast of Sichuan Province. The results are as follows:
(1) the design of seismic acquisition and observation system based on GIS 3D terrain visualization technology is designed for the design of seismic acquisition 3D observation system based on the assumption of horizontal surface conditions, which can not meet the requirements of the construction design under the complex surface conditions.
(2) to solve the problem that the data display efficiency of the 3D visualization system at home and abroad is not high, and the perspective and stereoscopic sense of many details are lack, and the data paging management and display have been adopted to solve the problem that the data display efficiency of the original visualization system is not high.
(3) in view of the single problem of the original seismic acquisition 3D observation system, a change view based on three dimensional GIS is proposed, which solves the single problem of the three-dimensional observation system based on the horizontal surface.
(4) aiming at the problem that the original seismic acquisition 3D observation system only supports the Windows system platform, the cross platform graphics and 3D engine technology based on Qt and OSG are proposed, so that the seismic acquisition 3D observation system supports multiple operating systems (such as Windows, Linux, etc.).
The application of the 3D observation system for seismic acquisition in Northeast Sichuan shows that the use of GIS 3D visualization technology makes the seismic acquisition design more scientific, and helps to improve the precision of the three dimensional observation system under the complex surface conditions, thus reducing the construction cost.
