摘要
起伏地表(黄土塬、沙漠和山地)进行三维地震勘探资料采集,不但要避开地表障碍,还要避开峰顶和陡坡(即:避高、避陡)。论述了适用于地震勘探采集设计的数字高程模型地形属性分析计算和特征提取的数字信息处理技术和方法,研究起伏地表三维地震资料采集观测设计中的数字地形应用原理,实现三维地震资料采集观测设计的避高、避陡自动优化设计,为三维地震勘探采集设计数字高程模型的应用提供了研究基础。
The three-dimensional seismic exploration data collection from undulating surface( loess plateau,desert and mountain) not only avoids surface obstacle,but also avoid peak and steep slope( ie,avoid high and avoid steep). This paper mainly discussed the digital information processing technology and method of terrain attribute analysis and feature extraction for digital elevation model which is suitable for seismic exploration and design,and studied the application principle of digital terrain in 3 D seismic data acquisition and observation of undulating surface to realize 3 D seismic data acquisition,the design of the observation design avoids and avoids the automatic optimization design,which provides the research foundation for the application of the digital elevation model for the 3 D seismic exploration acquisition design.
