Zusammenfassung:The invention provides a surface wave frequency dispersion curve pickup method and device. The method comprises the following steps: generating a surface wave frequency dispersion spectrum according to collected seismic data; acquiring preset pickup parameters, wherein the pickup parameters comprise an initial speed range and an initial search frequency; determining an initial frequency dispersion point according to the initial search frequency, the initial speed range and the value of the surface wave frequency dispersion spectrum; and picking up a surface wave frequency dispersion curve of the surface wave frequency dispersion spectrum according to the determined starting frequency dispersion point and preset picking parameters. According to the invention, automatic pickup of the surface wave discrete frequency dispersion curve is realized, the pickup time is saved, and the working efficiency is improved. 本发明提供了面波频散曲线拾取方法及装置,方法包括:根据采集的地震数据生成面波频散谱;获取预先设定的拾取参数,所述的拾取参数包括:起始速度范围、起始搜索频率;根据起始搜索频率、起始速度范围以及面波频散谱的值确
