Description
技术领域 technical field
本发明属于地理信息系统技术领域,涉及以航拍图为对象的数字地图制作方法。 The invention belongs to the technical field of geographic information systems, and relates to a method for making digital maps with aerial photographs as objects.
背景技术 Background technique
数字地图是通过数字化的方法,把城市地理信息以计算机可识别的格式存储起来,并能以连续地图的形式呈现出来,本质上是一个城市地理数据库。 A digital map stores urban geographic information in a computer-recognizable format through digitization and presents it in the form of a continuous map. It is essentially an urban geographic database.
数字地图为人们的生活带来了极大的便利,可提供丰富的基于位置的服务,如查找各种位置,各种场所,查找出行路线。数字地图与电子商务系统相结合,可动态显示连锁店位置、配送目的地分布,计算最短路径,优化配送方案,实现优化管理等等。与GPS相结合,可实时监控移动物体及车辆运行情况,实现远程管理。与电子政务相结合,可广泛应用于能源、交通、农林、土地、城建、旅游和军事等各个领域,直接服务于政府管理和决策分析,为国经济建设和社会发展提供支撑。 Digital maps have brought great convenience to people's lives, and can provide a wealth of location-based services, such as finding various locations, various places, and finding travel routes. The combination of digital map and e-commerce system can dynamically display the location of chain stores, the distribution of delivery destinations, calculate the shortest path, optimize the delivery plan, and realize optimized management, etc. Combined with GPS, it can monitor moving objects and vehicle operation in real time, and realize remote management. Combined with e-government, it can be widely used in various fields such as energy, transportation, agriculture, forestry, land, urban construction, tourism, and military affairs, directly serving government management and decision-making analysis, and providing support for national economic construction and social development.
然而数字地图的制作是很困难的,在知识上需要掌握空间变换类型、几何变换算法、矢量与栅格数据模型特点、数字地图数据结构等知识,在制作流程上需要经过八步:图像几何矫正、数字化地图、地图数据拓扑处理、数据转换、地图配色处理、添加地图标注、使用GPS控制点对地图进行验证、对地图进行重新矫正,在软件使用上需要涉及到AutoCAD、MapInfo、ArcInfo、PhotoShop、ErDas Imagine等等。这么多的知识点、制作流程和软件的使用使得地图的制作不仅专业性很高,而且成本也很高。 However, the production of digital maps is very difficult. In terms of knowledge, it is necessary to master the knowledge of spatial transformation types, geometric transformation algorithms, characteristics of vector and raster data models, and digital map data structures. Eight steps are required in the production process: image geometric correction , digital map, map data topology processing, data conversion, map color processing, adding map annotations, using GPS control points to verify the map, and re-correcting the map. The software needs to involve AutoCAD, MapInfo, ArcInfo, PhotoShop, ErDas Imagine and more. The use of so many knowledge points, production processes and software makes the production of maps not only highly professional, but also very costly.
除了对专业性和制作成本有很高的要求,数字地图制作的很多工作需要手工完成,因此工作量非常巨大,这造成目前用户使用的数字地图除了河流,桥梁等必须标出的物体外,很少涉及居民楼等非典型建筑物体的标识,从而使得数字地图可容纳的信息很少。现有数字地图制作技术存在的专业性强,制作成本高,手工工作量大等缺陷。 In addition to the high requirements on professionalism and production cost, many works of digital map production need to be done manually, so the workload is very huge. The identification of atypical building objects such as residential buildings is seldom involved, so that the digital map can hold very little information. Existing digital map production technology has defects such as strong specialization, high production cost, and heavy manual workload.
