资源简介

摘要: 近海养殖区是重要的海洋灾害承灾体,开展基于遥感技术的近海养殖区提取研究,对快速掌握沿海地区基础信息、减轻与防御海洋灾害有重要意义。利用国产高分系列遥感卫星图像,以福建省东山岛海域为实验区,在分析近海养殖区光谱特征的基础上,构建特征指数提取光谱特征,利用灰度共生矩阵的方法提取养殖区纹理特征,经过特征选择后融合养殖区的光谱与纹理特征,实现特征降维生成新特征,最后利用Otsu阈值法分别提取筏式养殖区与渔排网箱养殖区两种近海养殖区,实现对近海养殖区的高精度提取与分类。最终筏式养殖区的提取精度在80%以上,鱼排网箱养殖区的提取精度在90%以上,养殖区整体提取精度可达87%。  关键词: 近海养殖区;  目标识别;  特征融合;  比值指数;  高分遥感     Abstract: Coastal aquaculture areas are the important marine disaster bearing body,it is of great significance to carry out the research about automatically extraction aquaculture areas based on remote sensing for master basic information of coastal areas,mitigation and prevention of marine disasters.Used Gaofen-2 images for experimental data,and chose Dongshan Island sea in Fujian province as the experimental area,on the basis of analyzed the spectral characteristics of the aquaculture areas,construct feature index to extract spectral feature,used gray-level co-occurrence matrix method to extract the texture feature of the aquaculture areas,fused spectral features and texture features after feature selection,then used Otsu method to determine the threshold for raft culture area and fishing cage culture area,to achieve high precision intelligent extraction and classification for coastal aquaculture areas.The extraction accuracy of the raft culture area is more than 80%,and the extraction precision of the fish cage culture area is above 90%,and the overall extraction precision of the culture area is up to 87%.
