摘　　要：在全国土地调查过程中,土地确权的地块边界选取需要手动点取标定,工作量较大。针对目前栅格影像权属标记存在的效率问题,研究一种栅格图像矢量化技术,提高了土地边界标记的效率。矢量化技术主要包括图像预处理、形态学处理、图像分割、图像矢量化和图像融合过程。栅格矢量化技术在土地调查软件的集成融合,实现栅格矢量化技术的应用转化,可大幅度提高土地影像栅格矢量化工作效率。In the process of national land survey,manual point demarcation is needed in the process of land boundary selection,which is a heavy workload. Aiming at the problem of the efficiency of the ownership labeling of raster image,a raster image vectorization technology is studied to improve the efficiency of land boundary labeling. The vectorization technology mainly includes image preprocessing,morphological processing,image segmentation,image vectorization and image fusion. The integration of raster vectorization technology in land survey software and the application transformation of raster vectorization technology can greatly improve the efficiency of raster vectorization of land image.
