Other Abstract

Due to tunnel digging and path flattening, railway construction in mountainous region will produce a large amount of abandoned dregs, so it is necessary to build enough dreg deposition fields along the railway. The task of the department of soil and water conservation is to monitor the construction and usage of abandoned dreg fields according to the design in the whole process of railway construction. As long linear construction projects, railways in mountainous region will go through areas of complex terrain, which poses great difficulties to monitoring current status of abandoned dreg fields. With the advantages of low cost, flexible launch and landing, safety, under-cloud-flying, hyperspatial image resolution, Unmanned Aerial Vehicles (UAVs) are very
suitable for obtaining remote sensing imagery along the railway. One segment of the railway from Chongqing to Wanzhou and its neighborhood was chosen as the study area to demonstrate key technologies and specific procedures of monitoring abandoned dreg fields using the UAV remote sensing system. The process of investigating abandoned dreg fields of railway in mountainous region with UAV remote sensing system has the steps including flight trajectory planning, acquirement of imagery and attitude data, image preprocessing, and generation of DEM and DOM. Abandoned dreg field status investigation was done after the assessment of image-based measurement accuracy on the resulting DOM and DEM. Results prove that the image-based measurement accuracy fully satisfied the requirement and the fixed-wing UAV system was feasible and effective for rapidly investigate of the construction and usage of abandoned dreg ields of railway in mountainous region.
