| 摘 要： | 本文以广西兴安某测区为研究区,借助无人机和GNSS RTK分别获取1031张倾斜影像和3361个地面离散点,采用ContextCapture软件构建测区三维模型,利用EPS提取的测区三维模型高程点和GNSS RTK实测离散点分别进行DTM土方量计算。假定实测离散点的计算结果为真值,结果表明,无人机土方量测算结果与真值之差为1 050.9 m3,误差比例为0.9%。无人机倾斜摄影测量技术可快速、低成本、高质量地完成测区土方量测算,为工程项目提供精确的结果和科学的数据支撑。

| Abstract: | In this article, Guangxi Xing’an survey area is taken as the study area, and 1031 tilt images and 3361 ground discrete points were obtained with unmanned aerial vehicle(UAV) and GNSS-RTK respectively. The ContextCapture software is used to construct the 3D model of the survey area. The elevation points of the 3D model of the survey area and the measured discrete points of GNSS-RTK are extracted by EPS to calculate the DTM earthwork volume. Assuming that the calculated results of the measured discrete points are the true values, the results show that the difference between the measured results and the true values of the UAV earthwork volume is 1050.9m3, and the error percentage is 0.9%. UAV oblique photogrammetry technology can quickly, low cost, high quality to complete the measurement of earthwork and provide accurate results and scientific data support for engineering projects. |
