常州市焦溪古桥精细测绘
|
摘要
以常州市焦溪古桥中的青龙桥测绘为例,对比多种常规测绘方法,结合焦溪古桥特点,发掘适合该类建筑的测绘方法。采用近景摄影测绘,通过现场拍摄的古桥照片快速生成三维模型,结合传统测绘方法控制模型尺寸,并对古桥的细部数据进行手工记录,最终通过计算机辅助制图形成完整的古桥平面、立面、剖面及大样图,导出多种软件支持的模型以及正投形图片,为古桥的的保护和修缮打下基础。
This paper takes the surveying and mapping of Qinglong Bridge,one of the ancient bridges in Jiaoxi Town of Changzhou,as an example. By comparing various conventional methods,this paper explores the surveying and mapping method suitable for ancient bridges of this kind based on the characteristics of ancient bridges in Jiaoxi. Close-up photogrammetry,together with photos taken on the scene can quickly generate the three-dimensional model. Traditional surveying and mapping methods can help control the size of the model. The detailed data of the ancient bridge are recorded manually. Finally,through computeraided mapping,a whole set of plan,elevation,section and detailed drawing of the ancient bridge is formed,and the model applicable for a variety of software can be derived. It lays the foundation for the protection and repairs of ancient bridges.
