摘要: 2008年6月以来青岛近海出现的大面积浒苔对青岛奥帆赛场造成严重影响。如何快速、准确地发现浒苔,对治理浒苔具有显著的指导作用。采用卫星遥感数据,尤其是SAR数据对浒苔进行监测,运用一种基于区域增长面向对象的影像尺度分割方法,调整影像的分割尺度,快速提取浒苔信息,在浒苔遥感监测中效果显著。Abstract: Entermorpha prolifera blooming of a large area in Qingdao sea since June 2008 has seriously impacted Olympic sailing venue.How to fast and correctly monitor Entermorpha prolifera candirect to deal with Entermorpha prolifera cleaning.By using SAR data, a segmentation method is proposed based on object-oriented region growth, which can adjust image segmentation scale.Entermorpha prolifera information can beea extracted thus.The results show that this method is useful for Entermorpha prolifera monitoring.
