精品 本科毕业论文 论文题目： 1:1000航测数字化地形图技术设计 作者姓名： 学 号： 08201050108 专业班级： 08测绘（一） 指导老师： 完成时间： 2012-6-5 摘要 数字摄影测量是基于数字影像和摄影测量的基本原理，应用计算机技术、数字影像处理、影像匹配、模式识别等多学科的理论与方法，提取所摄对像以数字方式表达的几何与物理信息的摄影测量学的分支学科。在航空摄影测量学方面,地形图的成图方法已从模拟摄影测量、解析摄影测量发展到目前的数字摄影测量。本次设计的主要内容是：首先、先对本地区进行平面控制测量，将采用D级和E级静态GPS测量方法，高程控制测量采用四等水准测量方法。其次、通过飞机用航摄仪对测区进行航空摄影,获得该地区的航空摄影像片，然后通过全数字摄影测量系统和加密软件在室内进行像片控制点的加密，如果出现漏测和未能识别的地物和地貌就必须进行必要的补测；最后按照《图式》、《规范》的规定对采集的矢量数据进行编辑成正式地形图成果。最后上交整个过程中每一步的原始资料和成果资料。 关键词：数字摄影测量 航空摄影测量 ABSTRACT Digital photogrammetry is the basic principle of measurement based on digital imaging and photography, computer technology, digital image processing, image matching, pattern recognition and multi-disciplinary theories and methods to extract the photo on the geometrical and physical information as digital expression the photogrammetry learn subdiscipline. Aerial photography, surveying, mapping of the topographic map from analog photogrammetry, analytical photography measurements to the current digital photogrammetry. The design of the main elements are: first horizontal control measurements in this region, will use the D and E static GPS measurement methods, elevation control measure fourth-leveling. Followed by the aircraft The aerial survey area aerial photography, aerial photography photo for the region, and then by full digital photogrammetry the system and encryption software in the indoor photo control point encryption, if there is leakage measurement and failed to identify the surface features and landscapes must be necessary and supplementary; compiled into the official topographic maps of the outcome of vector data collected in accordance with the provisions of the schema, norms. Finally, to hand over the whole process every step of the raw data and results data. Keywords：Dig
