| 摘 要： | 在嵌入式系统中，由于内存资源有限，若将大数据量像素地图一次性读入内存进行处理是不切实际的。该文通过构建图像金字塔模型，将像素地图分块、分层处理，对分块后的各标准块图像进行配准，利用其地理坐标与像素坐标之间的映射关系实现了标准块的无缝拼接，并通过实验验证了其有效性。

| Abstract: | Because of limited memory in embedded system, it is always impractical to read into and deal with the raster map with macro data into memory as a whole. So, this paper disposes the raster map with tile and hierarchy through building the image-pyramid model, and aligns each standard block image. It accomplishes the seamless splice of standard block using the mapping relation between geographic coordinate and image coordinate and proves its validity.through the practice. |
