摘要
近年来,地铁以其车速快、行车密度大、客流量大等特点成为解决交通拥堵的重要措施之一,与此同时,地铁由建设期转入养护期,给线路安全检测带来了巨大的挑战。本文通过摄影测量的方法,采用光束法平差等方法对影像进行拼接,进行管理图展开图的制作,方便对地铁进行维护以及入库管理等。
In recent years,subways have become one of the important measures to solve traffic congestion due to their fast speed,high traffic density and large passenger flow.However,at the same time,subways have moved from the construction period to the conservation period.It has brought great challenges to the safety inspection of the line.In this paper,through the method of photogrammetry,the method of bundle adjustment is used to splicing the images,and the unfolded-drawings is made to facilitate the maintenance of the subway and the management of the warehouse.
