摘要
3维电子地图的打印输出是3维地理信息系统的基本功能之一,针对3维场景的大幅面、高质量输出问题,设计了大场景分块输出、序列图像自动拼接的打印输出算法。全面阐述了提高3维电子地图打印输出幅面和图像质量的方法和步骤,介绍了打印输出的3维电子地图图面整饰内容,解决了大范围多分辨率3维电子地图打印输出问题。
Printing out of 3D electronic map is a basic function for 3D geographic information system.To solve large high quality 3D scene printing out,the large image converting to serial small image was designed which was able to automatic merge.And the way and step of printing out large high quality 3D scene was described.Map beautifying for 3D electronic map was also introduced,which solved the printing out of large scale and multi-resolution 3D electronic map.
