水陆三维地形地貌融合应用研究

针对海量遥感数据和海洋测量数据的特点,采用Kriging插值算法和三角网构建高精度水下DEM数据,应用标准偏差算法和侧扫声纳镶嵌技术制作水下地貌影像,实现多元数据处理、融合和三维显示的技术流程.应用像素级数据融合技术实现海量水陆数据的连续、准确无缝拼接,解决海洋测绘信息空间一体化表达的技术难题.

Research on the Application of Fusion of Underwater Three-dimensional Terrain and Relief

In this article it aims at the characteristic of great capacity remote data,hih resolution underwater DEM is constructed applying Kriging algorithm and triangle network.And it is used the standard warp algorithm and side-sonar mosaic technology to product underwater relief image.Therefore it is the technology flow to be summarized that the multi-data is processed,fused and displayed three-dimensionally.Applying the pixel level fusion technology realizes the continuous correct seamless mosaic of great capaci...
